HP StoreOnce 6500 (88TB) Capacity Expansion guide (BB897-90914, January 2014)

4. Wait for the LUN creation process to complete, then run the following StoreOnce CLI command
in order to format the storage LUN with file system segments:
hardware add storage
IMPORTANT: If you run the hardware add storage command before the LUN creation
process completes, the amount of time required to complete parity initialization cannot be
predicted because it depends upon the workload of the system. It may take several days to
complete and performance will be impaired.
5. This command will expand the filesystem to use the storage. The process can take up to four
hours to complete per file system on each couplet in the cluster.
6. Monitor the expansion using StoreOnce CLI commands.
