Module 7: Storage Space Management

In this module, I experiment with Space Guarantees and File Reservation, Configure Deduplication services for a Volume, and  Create a Quotas for all users of the qtree, and Create a Quota for an existing qtree and modifying an existing Quota.

Quotas provide a way to restrict or track the disk space and number of files used by a user, group, or qtree. Path of the quotes:  /etc/quotas file.

We use quotas in the Storage system to limit resource usage. It will give us notification when resources usage reached the specific level that we defined or also track usage of resources. Quotas working with users and group, and qtree. When a quota is created with a qtree, it is called tree quota.

The tasks for the module 7: 

  • Explore file space consumption
  • Configuring deduplication for a volume
  • Create and Manage quotas
  • Generate a quota report
  • Modify the /etc/quotas file and implement quota changes

Steps for the task: Explore file space consumption

In this task, I will discuss how to explore file space consumption. I will create a volume with space reserved for file and create fully provisioned and thin provision file with it

Step 1: Create a new volume with 30 MB in aggregate 1 for reserved space for the files FileVol

vol create Filevol -s file aggr1 30m

 

Step 2: Mount FileVol

#mkdir /mnt/dataontap/Filevol

#mount 192.168.1.15 (IP_Address) :/vol/FileVol/mnt/dataontap (system_name)/FileVol

Step 3: Create a fully provisioned 10 MB file in FileVol that is called FULLfile

#cd /mnt/dataontap/FileVol

#dd if=/dev/zero of =FULLfile bs =1000 count =100000

Step 4: Create 10MB file called SPARSEfile in FileVol

#dd if =/dev/zero of =/SPARSEfile bs=1 count = 0 seek = 100000

Step 5: add a overwrite  protection to FULLfile

file reservation /vol/FULLfile enable

Step 6: add overwrite protection to SPARSfile

file reservation /vol/FILEvol/SPARESfile enable

3

Steps for the task: Configure deduplication for a volume

In this task, I will configure deduplication on NASvol

Step 1: First you need to add license for the deduplication services on Storage System

The license of deduplication is A-SIS.It is integrated with Data ONTAP software and the WAFL file system.

For the deduplication, you need to enable the “nearstore option NetApp storage system”

options licensed_feature.nearstore_option.enable

If options licensed_feature.nearstore_option.enable is off,

turn it on

options licensed_feature.nearstore_option.enable on

options licensed_feature.nearstore_option.enable

1

Check your license list

2.jpg

Step 2: Now I will turn on and check the status of the deduplication services on NASvol by the following command

sis on /vol/NASvol

sis status /vol/NASvol

3.jpg

Step 3: In this step, I will configure the deduplication service on NASvol to run on the flexible volume with percentage level of fingerprints in the change log reached the default threshold 20% by the following command

sis config -s auto /vol/NASvol  [ This configuration only for the future data]

4.jpg

Step 4: Now I will start the deduplication process for the existing data by the following command

sis start -s /vol/NASvol

Press “Y” for confirmation

df -s /vol/NASvol                   [ for checking the space saving]

 

5.jpg

Steps for the task: Create and Manage Quotas

In this task, I will use NetApp OnCommand System manager to create and manage quotas.

Step 1: Click Storage -> Qtrees in the NetApp OnCommand System manager. Click Create for creating a new qtree for NASvol with enabling oplocks and NTFS Security

 

7.jpg

8.jpg

10.jpg

Step 2:  In this step, I will create a CIFS share for nas_tree1 in the NetApp OnCommand System manager.11.jpg13.jpg14.jpg15.jpg

Step 3: Before creating a new quota, I will check the current value in the /etc/quotas file by the following command line

rdfile /etc/quotas

12.jpg

The output: #auto-generate by setup means user setup the tight restriction intentionally.

Step 4:  Now I will create a Quota using NetApp OnCommand System manager.

Click Storage -> Quotas ->Create 16.jpg16.jpg

17.jpg

Click next and entry the quota limit for Space Usage and file count 18.jpg

Click Next and Review the Summary of the quota configure19.jpg20.jpg21.jpg

Step 5: Now I will show how to check quota status and current value in the /etc/quotas file by the Storage System CLI

quota status   [ checking quota status]

rdfile /etc/quotas [verify the current value of quotas file]

22.jpg

Step 6: Navigating the nas_tree1 as Map Network Drive

Computer -> Map Network Drive23

Enter the folder path \\IP of Storage System \nas_tree1

24.jpg

Give the domain\Administrator  and Administrator password to establish connection

25.jpg

26.jpg

Step 7: Add at least 8MB of data to the nas_tree1 to check the threshold

27.jpg

28.jpg29.jpg

Steps for the task: Create a Quota Report

In this task, I will create a quotas report using Storage System CLI  and NetApp OnCommand System manager.

Step 1:  View the Quota report by the following command on CLI

quota report

30.jpg

Step 2: In the NetApp OnCommand System manager: click Storage -> Quotas

Click Quota Report tab and compare the value with the CLI output

29.jpg

Steps for the task: Modify the /etc/quotas file and implement quota changes

In this task, I will show how to modify the /etc/quotas file and implement quota changes after threshold exceeded

Step 1: Click the User Defined Quotas tab in the NetApp OnCommand System manager31.jpg

Step 2: Change the hard space quota from 12 MB to 15 MB from Edit Setting -> Space Limit

32.jpg

33.jpg

34.jpg

Step 3: Now click on the Quota Status on Volume tab. You can see each volume is listed with its quota status

35

Step 4: Select the NASvol volume and click the resize button to cause changes to the hard space to take effect

36.jpg

Step 10: From the Storage System CLI, I will again check the values in the /etc/quotas file to monitor the effect of change

rdfile /etc/quotas

37.jpg

Step 11: Try to exceed the limit of the quota

38.jpg

Thank You 🙂

Lab 23: Configuring VMware vSphere Fault Tolerance

In this lab, I am going to discuss how to configure vSphere FT for Virtual Machine and how to verify that vSPhere FT is working with Virtual Machine.

vSphere FT provides a higher level of availability, enabling users to protect any Virtual machine from the host failure without any data loss or transaction interrupt or connection.

vSphere application is used for a mission-critical application system that can not tolerate any downtime or data loss. It is required for that business which has long-lasting client connections.

The tasks list for this lab 23:

  • Prepare the Virtual Machine
  • Enable the vSphere FT Logging
  • Activate the vSphere FT Protection
  • Test the vSphere FT Configuration
  • Disable and Turn off vSphere FT Protection

Prerequisites:

  • Log in the VMware vSphere web client portal: https://vCenter Server Appliance Name.domainname:9443/vshpere-client/# or VMware vSphere Client via root user and password.

Steps for the task: Prepare the Virtual Machine

In this task, I am going to prepare a VM that will be capable of using vSphere FT in a nested VMware ESXi environment.

Step1: Home ->vCenter ->VMs and Templates

Right-Click on the VM and Select Edit settings

1.jpg

Step 2: Click CD/DVD Drive 1 from the Hardware Section. Select “Client Device” and Device Mode ” Passthrough CDROM” from the Virtual Hardware section2.jpg

Step 3:  Go to the “VM Options tab and click the arrow next to Advanced.  Click “Edit Configuration”3

Step 4: In the Configuration Parameter

reply.supported = true  from false

4.jpg

Add two more new parameter

replay.allowFT = true

replay.allowBTOnly=true

5.jpg6.jpg

Steps for the task: Enable the vSphere FT Logging 

Before enabling vSphere FT Logging, you need to enable vSphere HA Cluster on each host, configure two VMKernel ports for ensuring that hosts are supported vSphere FT.

Step 1:  Go to the Home -> vCenter -> Hosts and Clusters -> Summary

Verify the Host configuration for FT status = NO [current state]1.jpg

Step 2: Manage -> Networking -> VMkernel Adapters

Select vMotion from the Edit Setting 2.jpg

Enable the Fault Tolerance Logging. Click “OK”3.jpg4.jpg

You may see that ” Host Configuration FT = NO” after enabling vSphere FT Logging because, in this lab, I installed ESXi host on Virtual hardware. But it will not affect on the fault tolerance testing5.jpg

Step 3: Repeat Step 2 for the second host as well

Steps for the task: Activated the vSphere FT Protection

After enabling each host for vSphere FT in the Cluster, you can feature it on individual machines by turning on the fault tolerance.

Step 1: Select Home -> vCenter -> Hosts and Clusters

  • Select the VM that you prepared for fault tolerance activity in task 1
  • If the VM is powered on. Turn it Powered off before Turn on Fault Tolerance feature
  • Right-Click on the VM -> All vCenter Actions -> Fault Tolerance -> Turn On Fault Tolerance

6.jpg

Press “Yes” to give confirmation7.jpg

Step 2: In the summary tab of the VM, Find out the Primary VM location and the Secondary host Location

The Backup VM is called a Secondary Virtual Machine which is automatically created the corresponding host of the primary VM location.1.jpg2.jpg3.jpg4.jpg

Step 3: Powered on FT VM and noted the changes happened in the summary tab

5.jpg6.jpg7.jpg8.jpg9.jpgfinal VM 2.jpg

Steps for the task: Test the vSphere FT Configuration

In this task, I am going to test the FT configuration

Step 1: Log in the secondary location host of VM FT through the Vsphere Client. You can see here a secondary VM has been created automatically in the second location of FT VM which is host vesxi.momataj.local

1.jpg

Step 2: Check the Primary location of FT VM esxio02.momataj.local from Related Objects -> Virtual Machine and make sure that VM is powered On2

Step 3: Open Console of Primary VM and Secondary VM and Log in as Administrator user. Here “momo” is the administrator user for this FT VM3.jpg4.jpg5.jpg

Step 4: Go to the command Prompt and type ” ipconfig ”

Ping the Ip address from the primary FT VM, You will see secondary FT VM is starting to running ping command equally.

6.jpg

Step 5: Go to the vSphere web client of your primary FT VM. Right-click on FT VM -> All vCenter Actions -> Test failover. It will stimulate a Primary VM is failure7.jpg

Step 6: You can now both console windows have displayed the primary. 8.jpg

Step 8: after failover, the Primary FT VM location has changed. It now belongs to the Secondary host location: “vesxi01.momataj.local”.9.jpg

Steps for the task: Disable and Turn Off vSPhere FT Protection

After turning off vSphere FT for a virtual machine suspends its fault tolerance protection and release the secondary VM but preserving the configuration and history of fault tolerance activated the machine. If you disable the vSphere FT for a Virtual machine,  its fault tolerance protection by halting the secondary VM.

Step 1: Right-click Protected VM -> All vCenter Actions -> Fault Tolerance -> Turn off Fault Tolerance

Recommendation: Use an alternative virtual NIC e1000, VMXNET2 (Enhanced), Flexible or VMXNET3

Thank You 🙂

Lab 20: Using Alarms

In this lab, I am going to demonstrate the vCenter Server Alarm Feature

An Alarm is a notification that mainly occurs in response to selected events and conditions that happen with an object in the inventory.  The alarm is the important to monitor the vCenter inventory because it is very difficult to check each of inventory activities manually. It gives you acknowledge of the object’s activities in the vCenter Server inventory.

By default, VMware provides a set of predefined alarm for the objects in the vCenter Server inventory. But You can also define your own custom alarm for your resources in the vCenter Server inventory.

VMware predefined alarms are configurable. You can edit, modify it if it does not fulfil your requirement such as condition, state or event that you want to monitor.

The tasks for the lab 20:

  • Create a Virtual Machine Alarm that Monitor for a Condition
  • Create a Virtual Machine Alarm that Monitor for an Event
  • Trigger Virtual Machine Alarms and Acknowledge the Alarm
  • Disable the Virtual Machine Alarms

Prerequisites:

  • Log in the VMware vSphere web client portal: https://vCenter Server Appliance Name.domainname:9443/vshpere-client/# or VMware vSphere Client via root user and password.

Steps for the task: Create a Virtual Machine Alarm That Monitors for a Condition

In this task, I am going to create a VM alarm for monitoring VM activity with a condition.

Step1: Go to the Home -> vCenter -> Hosts and Clusters1.jpg

Step 2: Select the name of the VM in the inventory for setting alarm. In my case, I chose “momatajvmclient 1-2” for performing this task. Note: As I am creating this alarm for “momatajvmclient 1-2” specific Virtual machine, this alarm only monitors that   “momatajvmclient 1-2” VM. If you create the alarm on the vCenter Server object, the alarm will apply to all VMs in your system.

Select Manage -> Alarm Definitions Note: VM inherited alarms defined at the vCenter Server level

Click “Add” (+)2.jpg

Step 3: A new Alarm Definition wizard is displayed. Now you need to perform the following action that I showed on the Screenshot.

Option 1: General tab:

Alarm name: Give an appropriate name. I gave VM CPU Usage-Momataj

Description: Blank

Alarm type: Virtual Machine  from drop-down menu

Monitor for: Select Specific Conditions or State, for example, CPU Usage

Enable the alarm: Selected

3.jpg

Option 2: Trigger -> Click Add (+) 4.jpg

Perform the following action to set a trigger for the alarm.

Option: Trigger name: VM CPU Usage

Operator: Is above

Warning Condition: Double click the current value on the column and set it 25% for 30 Minutes. That means after 25% CPU usage in 30 minutes, the trigger condition must trigger a warning alarm.

Condition length: 30 seconds from the drop down menu. That means  Trigger will take 30 seconds to generate an alarm.

Critical Condition: 50% for 5 minutes. That means: Above 50% for 5 minutes will be considered as critical condition for CPU and trigger must generate an alarm

5.jpg

Option 3: Action.  Click add (+) icon. Note: An action specifies when the alarm is triggered. It is an operation that occurs in response to the trigger such as send an email notification to the administrator.6.jpg

Now you need to configure the following action settings for generating an alarm.

Action: Click ” Send a Notification email below the action header to activate the drop-down menu. Select Suspend VM from the list.

Configuration: leave it blank

Green to Yellow: Select “Once”

Leave rest of the setting by default.7.jpg

Step 4: Verify that newly created alarm from the list of the alarms8.jpg

Steps for the task: Create a Virtual Machine Alarm that Monitors for an Event

Event triggers use arguments, operators, and values to identify the triggering condition. It does not rely on the thresholds or durations.

Creating an alarm comprises setting up general alarm, triggers, triggers reporting and alarm actions.

Step 1: Select Home ->vCenter ->Hosts and Clusters -> datacenter in the inventory

Step 2: You need to perform the following configuration to set alarm action as I showed the following on the screenshot11.jpg12.jpg13.jpg

Step 3: Verify your newly created alarm from the alarm definition list: VM Suspended-Momataj [in my case]14.jpg

Steps for the task: Trigger Virtual Machine Alarms and Acknowledge the Alarms

The acknowledge alarm feature is used to track when triggered alarm is addressed. When you acknowledge an alarm, its alarm actions are discontinued and the

alarm is neither cleared nor reset.

Step 1: Click on the VM for that you configure the alarm [ momatajvmclient1-2] I configured alarm so I am going to select it and triggering an alarm on this specific VM.

Monitor -> Issues-> Triggered Alarms

Step 2: Right click on your VM and select Open console. Log in your VM as I did.

Run the “Cpubusy.vbs” script with “Open with Command prompt17.jpg

Step 3: Monitor the performance of your VM CPU Usage. Monitor -> Performace -> Advanced18.jpg

Step 4: After waiting 30 seconds, the alarm is triggered. You can monitor it from “Recent Task” Activity name is: Suspended Virtual Machine19.jpg20.jpg

Step 5: You can monitor it also from Monitor -> Tasks21.jpg

Step 6: Monitor -> Issues: Now you can see an issue there: VM Suspended-momataj22.jpg

In the triggered alarm, you can see critical trigger alarm with red warning sign

Verify the suspended alarm from the summary. You can see VM is showing “Suspended”25.jpg26.jpg

Step 8: Now Power on the Suspended Virtual Machine 27.jpg

Stop the CPU busy script by pressing Ctrl+C28.jpg

Step 9: Go to the ” Monitor -> Issues -> Triggered Alarm  and Click on Critical Severity and Select “Reset to Green29.jpg30.jpg

Steps for the task: Disable Virtual Machine Alarms

In this task, I am going to show how to disable the alarm for the object on which alarm was defined. Note that, You can enable the alarm again after disabling it.

Step 1:  The first task is to disable the VM CPU Usage Alarm

Select you VM on which you applied the alarm in the inventory.

Click Manage -> Alarm Definitions Tab . Righ-Click on your VM CPU Usages alarm and Select Edit.

Lab 19: Monitoring Virtual Machine Performance

In this lab, I am going to discuss how to system monitoring tools reflect CPU workload

The tasks list for the lab 19:

  • Create CPU Activity
  • Use vSphere web Client to Monitor CPU Utilisation
  • Undo Change Made to the Virtual Machines

Prerequisites:

  • Log in the VMware vSphere web client portal: https://vCenter Server Appliance Name.domainname:9443/vshpere-client/# or VMware vSphere Client via root user and password.

Steps for the task: Create CPU Activity

In this task, I am going to run a CPU busy scripts in each of the VMs for creating a heavy CPU load.

Step 1: Go to the Home -> vCenter ->VMs and Templates. Power On each of your VMs and Open it through console or VMRC. Log in as an Administrator user.1.jpg

Step 2: Run the CPU busy script “cpubusy.vbs”. Right-click on it and select “Open with Command Prompt”2.jpg

Steps for the task: Use vSphere Web Client to Monitor CPU Utilisation

In this task, I am going to show how to monitor CPU, memory, disk, Network, and Storage resources and how to use Resources metrics to follow up the performance by using performance charts

Step 1: Click your first VM in the inventory Note: Be sure that cpubusy.vbs script is running on that virtual machine.

Click the Monitor -> Performance tab. You will see “Overview view is displayed by default”

When I clicked on Performace tab, I got “Overview” view by default. 3.jpg4.jpg

Step 2: Click”Advanced” tab. You will see that Advanced tab is showing by default CPU usage in real time statistics.5.jpg

6.jpg7.jpg

Step 3: On the screen, You can see “Performace chart Legend” tab. Click on ” The name of VM”. The Chart Options link will be activated.  Note: You need to unpin the right column to make the like visible if you can not see it yet.

Click on Chart Options link:8.jpg

Step 4: The customise Performance Chart dialogue Wizard has appeared.

Select CPU. Select “Rea-time” from the “TimeSpan” drop-down menu. In the target object box: Deselect the check box with your Virtual Machine’s Name.

In the CounterPane: Click “None” to deselected counters. Only Select “Ready and Used”

Only Select “Ready and Used” counters. Then “OK”2.jpg

The Chart is displayed with graphical manner. You can now measure the real Time Performance of your VM CPU.3.jpg

Step 5: Repeat the Step 4 for the rest of the VMs. Compare the CPU busy “Ready” and “used ” chart performance with each other VMs.5.jpg6.jpg

Note: Performace chart update automatically every 20 seconds

Press Ctrl+C to stop the “cpubusy.vbs” in each VM after complete performance chart task.

Steps for the task: Undo Change Made to the Virtual Machines

Now I will show how to undo the change that happened to the VMs after performing the previous tasks. And I will delete the Scheduling affinity value from CPU setting that we put in previous labs.

Step 1: Close the CPU Performance Chart Options Web Browser window for each VMs

Close the VM Console for each VMs

Step 2: Right Click on VM, Select “Edit Setting”

In the Virtual Hardware, Click “CPU” and expand it. Delete the “1” from the text box in the Scheduling Affinity. Then Ok

Step 3: Repeat the Step 2 for the rest of the VMs in your environment.

Thank you 🙂
