The steps below assume that you have an Analytics VM, which already have an additional storage disk attached to it and you want to increase capacity of additional disk.
New installation of Analytics 2.5-2520 or above version is required to increase additional storage disk size.

Resolution

Procedure:

At high level user must perform following procedure to increase additional storage disk size

Step 1: Deployment of Analytics virtual machine

Step 2: Attach storage disks to Analytics virtual machine

Step 3: Copy data from existing storage disk to new storage disk.

Step 4: Add firewalls in new Analytics virtual machine.

Detailed Procedure:

Follow below steps to expand additional storage disk size of existing Analytics virtual machine, say VM-A by deploying new Analytics virtual machine, say VM-B.
We are explaining this procedure considering Analytics is deployed on VMWare and please follow equivalent platform specific workflow if your Analytics VM is deployed on another platform.

Step 1: Deployment of Analytics virtual machine
Create new Analytics virtual machine (VM-B) running version 2.5-2520 or above by following Analytics installation guide of desire platform. We do not have to add any additional storage disk to Analytics at this point.

Step 2: Attach storage disks to Analytics virtual machine
Attach additional storage disk of existing Analytics virtual machine, VM-A to VM-B.

Remove additional storage association from old virtual machine, VM-A by editing virtual machine settings.
After this we do not have to perform any configuration on old Analytics VM-A.
Attach storage removed in last step with new Analytics virtual machine, VM-B by editing virtual machine settings
Power on new Analytics virtual machine VM-B, launch management console and move to ‘Storage’ menu item to mount disk that we added in previous step.

You will be prompted to enter a key. Enter a keypass of your choice and hit enter. VM will reboot to complete disk mount

NOTE: Save this key as you will need it for performing any actions on the disk. If you lose the key, you lose your data.

After rebooting Additional storage action status will be disk is Ready for use

Now attach new virtual disk to Analytics VM-B. If you want to increase additional storage disk size from previous installation of Analytics VM-A, please configure desired higher capacity disk.
Boot Analytic VM-B in safe mode, in management console go to Reboot | Shutdown and in Boot Analytics into safemode sub menu chose Enable
Add new additional disk of desired capacity to Analytics VM-B, by editing virtual machine configuration.
Now, in Management Console, storage menu, choose disk added in previous step in ‘Available Additional Storages’. In below figure new disk is displayed as Disk C.
In disk action, chose ‘Add storage’ and confirm deletion of data from newly added virtual Hard Disk and provide desired key. System will now start to encrypt and mount new virtual hard disk

You will be prompted to enter a key. Enter a keypass of your choice and hit enter. VM will reboot to complete disk mount

Once the disk is mounted, you will see a menu option Active Disk will show the Enable button.

Step 3: Copy data from existing storage disk to new storage disk.
Now you can either choose to Backup data to Disk C and then use it as live disk or use the Disk C without old data.

If you want to backup data, Choose the Backup Data option. You will see a confirmation dialog after approving that, you will be prompted to enter the key for the disk

After entering the key hit Enter. You will see a dialog with progress of data copied. You can close the dialog by pressing Escape-key once you see a completion message
To use the disk as live disk, select the Active Disk menu option. You will see a confirmation dialog stating that this operation will restart the VM.

Once you approve, you will be promoted for entering the key. This operation will set Disk C as your default live disk and will restart the VM into normal mode. The VM now onward will use Disk C as Extra disk for Analytics.

Step 4: Add firewalls in new Analytics virtual machine.
Log into Analytics VM-B and add firewall using same ‘Firewall Name’ as in old Analytics VM-A. Check existing analytics data is available for all firewalls.
