NBU appliance unallocated disk space

[rookie11]

I have an NBU appliance 5240. It has additional disk shelfs attached. One of disk shelf has unallocated disk space of 7 TB . How can I use it.

Although you can do that, I would strongly suggest to use that space to move all deduplication off the base unit as described here https://www.veritas.com/content/support/en_US/doc/89578623-126714613-0/v93783977-126714613

You may also find additional space you can use on expansion shelves in the process, but more important you will likely see better performance because you won't be using the slow base unit disks

I think the unallocated disk space that rookie11 is refering to is the space on the expansion shelf: B00B7AA020FF000048047A5E3B. It doesn't look like the base unit is being utilized at all.

It is quite easy to resize the MSDP partition by using the CLISH. You enter the following commands:

Manage --> Storage --> Resize [SIZE] [GB/TB/PB]

Important things to note:

• With this command, you need to look at how big the current MSDP partition is across the whole appliance, and then add the free space to that. 
• You cannot control where the appliance takes free space from, you may risk it utilizing the free space on your base unit which Mouse correctly points out is slower. A way to mitigate this is to move your MSDP catalog to the base, and resize that to use the space there before you go and resize the MSDP parition
• You are resposible for the changes you make, so if you feel uncomfortable making the changes I would suggest contacting support to ask if they will help you perform this task the first time.
