Example 2
To assign multiple LUNs from a drive or group of drives, use the add unit command and include
the size= command option. Repeat the command using a unique LUN ID for each LUN, along with
the desired size parameter.
CLI> add unit 1 data=”disk111-disk114” raid_level=5 stripe_size=32 size=1000mb
First volume to be configured on these drives.
The logical unit size has been adjusted by 4MB for optimal performance.
Logical Unit size = 996 MB
RAID overhead = 498 MB
Total space occupied by new unit = 1494 MB
Free space left on this volume = 24533 MB
Unit 1 is created successfully.
CLI> add unit 2 data=”disk111-disk114” raid_level=5 stripe_size=32 size=2000mb
Logical Unit size = 2000 MB
RAID overhead = 1000 MB
Total space occupied by new unit = 3000 MB
Free space left on this volume = 21533 MB
Unit 2 is created successfully.
CLI> add unit 3 data=”disk111-disk114” raid_level=5 stripe_size=16 size=4000mb
Logical Unit size = 4000 MB
RAID overhead = 2000 MB
Total space occupied by new unit = 6000 MB
Free space left on this volume = 15533 MB
Unit 3 is created successfully.
Example 3
To create a LUN and assign a spare at the same time, use the add unit command and include the
spare= command option.
NOTE:
More than one spare can be assigned to the same LUN, and the same spare can be available to
multiple LUNs.
CLI> add unit 4 data=”disk211-disk212” raid_level=1 spare=”disk213”
First volume to be configured on these drives.
Logical Unit size = 69460 MB
RAID overhead = 69460 MB
Total space occupied by new unit = 138920 MB
Free space left on this volume = 0 MB
Unit 4 is created successfully.
