HP StoreOnce VSA Deployment and Configuration Guide (TC458-96024)

Storage addition problems
When adding storage to the StoreOnce VSA, the following guidelines apply:
• Always allow the StoreOnce CLI command, hardware discover storage, to complete
before running the command, hardware add storage.
NOTE: There are two StoreOnce CLI commands that perform the same function: hardware
discover storage and hardware prepare storage. The same comments apply to
both.
• If you add 1 TB data vdisks to the StoreOnce VSA and reboot it, the disks will be automatically
discovered by the StoreOnce VSA. This means there is no need to run the StoreOnce CLI
command, hardware discover storage. But you must still run the command, hardware
add storage.
• Do NOT remove any of the data vdisks from the StoreOnce VSA while or after executing the
StoreOnce CLI command, hardware add storage. This may lead to an unstable VSA and
even data loss.
Also note that:
◦ If you wish to re-configure the storage on the VSA, use the StoreOnce hardware delete
storage ALL command. This will delete all the data and the entire file system on the
VSA. To create a new file system, you may remove virtual disks, reboot the StoreOnce
VSA and present new virtual disks, and rerun the StoreOnce storage CLI commands. After
re-configuring the storage and file system on the VSA, wait for a maximum of one hour
to activate the license automatically back on the VSA.
◦ You should never remove or delete a VSA data vdisk that is already a part of the VSA
file system.
◦ The hardware delete storage node1_logicaldisk_1 command is not supported
on the VSA.
hardware discover storage / hardware prepare storage StoreOnce CLI command
fails
While adding new data vdisks to the StoreOnce VSA, the StoreOnce CLI command hardware
discover storage (or hardware prepare storage) may produce the following error:
Error: Storage provisioning was unable to complete the requested operation [Incorrect virtual disk size]
This command takes several minutes to complete execution.
Storage provisioning was unable to complete the requested operation [Incorrect virtual disk sizes]
Command Failed –
Cause
This can occur when data vdisks of incorrect size are added to the StoreOnce VSA. Virtual disks
added for user data must ALWAYS be 1 TB in size.
Solution
• Delete all data disks which are not 1 TB in size from the StoreOnce VSA using vSphere Client.
• Add the data vdisks again, making sure each is 1 TB.
• Reboot the StoreOnce VSA.
• Run the StoreOnce CLI command, hardware add storage.
