3. After the LUNs have been created, parity initialization starts. This can take up to 10 hours to
complete, see Planning for the Capacity Expansion (page 4). Log on to the StoreOnce User
Interface to check the status of this process. You need to check the Pools and Volumes
information for each storage cluster. There are up to 6 pools for each storage cluster. Expand
the Hardware tree to find the pool that is appropriate for this capacity expansion.
To check the progress of parity initialization, expand each degraded pool to check the status
of the Volumes. The following example shows the Hardware tree expanded to view the
information associated with the Volume in Pool C1_P2.
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.
6. Monitor the expansion using StoreOnce CLI commands.
