Expand a disk of StoreOnce VSA 3.x

[NKretschmar]

Hello community,

we noticed in a couple of a VSA 3.x deployments a low disk scenario, Those are running with a HA clustered VMware 6.5 environment, using a MSA 20x0 as a storage backend.

We were wondering, what needs to be done to increase the size of the available of the StoreOnce libraries and shares by adding disk space to the underlaying virtual disks on the VMware side.

I tried following already:

1. Increased the existing VM disk from 6 to 7 TB
2. Executed in the CLI : hardware discovery storage

This ended in this error

Storage provisioning was unable to complete the requested operation [ Incorrect virtual disk size. The system allows data disks of size in multiples of 1099511627776 bytes (1 TiB).. Please remove all incorrect size virtual disks and reboot the StoreOnce VSA before configuring additional storage. ]

Any suggestion to get the space extension done?

The expansion of VSA storage by increasing the VM disk size is not supported.

In order to add more capacity you will need to create new virtual disks (multiple of 1TB), assign them to the VSA VM then you can run the discovery and add commands.

You made my day!

Steps to success:

• Added a new disk to the VM with exact 1 TB size
• Rebooted the appliance
• Logged in to the CLI via SSH
• Executed hardware discover storage with this result

This command will take several minutes to complete, however it could take up to two hours depending on the amount of storage.
