Re-deploy VDP with existing storage

Written by Suhas Savkoor



You will come across instances where your VDP appliance has gone corrupt or the appliance is not booting at all no matter what fix you have implemented, in this case the simple and easy resolution would be to redeploy the appliance. When you redeploy the appliance in VDP, you will have an option to attach an existing storage to the appliance.

So your VDP appliance comprises of X number of disks, with the hard disk 1 always being your OS disk, and the remaining ones created to store backup data. Now, when you re-deploy the appliance, the OS disk is replaced completely. This means, your backup jobs or email configuration for the VDP appliance is lost. So, once the appliance is redeployed you will have to recreate your backup jobs. However, the backup data will be intact as it resides on the storage disk.

What you need to do:

So, here before discarding my old appliance, you can see the backed up virtual machine available under Restore of VDP.


Make a note of the data disks for the VDP appliance from the Edit Settings of the virtual machine.


Here the Hard Disk 1 is the OS disk hosting the backup jobs and the SMTP settings for VDP and DIsk 2/3/4 are the storage disk where the backup data will be stored.

Power OFF the old VDP appliance and remove it from the inventory.

Follow the OVF deployment procedure to deploy the new VDP appliance. Once the virtual machine is deployed, power it on and wait for the boot to be complete. Then browse to the vdp-configure page:
https://<VDP_IP>:8543/vdp-configure

Go through the initial configuration step, until you come across Create Storage. In this wizard, select Attach Existing VDP Storage and click Next.


Browse the location where the existing data disk for VDP resides. Select each disk one by one and mount them. There is no option to select all VMDKs at a time and perform the mount. This has to be done for each disks. It's going to validate each disk.


Once all the disks are mounted, then proceed Next and it's going to validate the set of disks.


Proceed ahead to complete, and each disk is imported and attached to the new VDP appliance, and a mount point is created for each disk. Reboot the machine once completed, and it is going to run a VDP: Configure task for about 15-20 minutes.


Once the appliance is configured, login to Web Client and connect to the appliance. Go to the Restore tab and you can see the backed up data still available. 


You will have to just reconfigure your backup jobs for the virtual machines.
