To create ESS logical unit numbers (LUN) and create Virtual logical unit numbers, you must use ICAT interfaces.
>>-repcli-- --lsvol-- --+----+-- --+-------------------+-- -----> +--s-+ '--devtype----ess---' '--l-' >--+--------------+-- --+------------------------+------------->< '--dev--dev_id-' '-volume_id--+---------+-' +-[. . .]-+ '---------'
You can use the lsvol command to display volume information and status to assist in choosing available volumes for groups and pools, and determining which volumes are in a suspend or error state
For each volume, the following information is listed:
Column Label | Details |
---|---|
ID | Volume ID |
Dev | The nickname or model-serial-manufacturer |
Dev Type | ESS |
LSS/IO Group | Displays LSS ID for ESS device type |
Vol Type | CKD or FB |
Size | Volume size |
Unit | Measure that the capacity is given in |
Status | Volume status |
An invocation example:
repcli lsvol -l -devtype ess
The resulting output:
ID Dev Dev Type LSS/Node Pair Vol Type Size Unit ================================================================================ ESS:2105.65312:VOL:202A 2105.65312 ESS 202A FB 20000 GB
