HP StorageWorks 1510i Modular Smart Array - Manual (Page 60)

• Create new logical drives on the array. (For more information, see
“ Creating logical drives ” on page 41.)
• Migrate the RAID level or stripe size of existing logical drives on the array (For more information,
see“ Migrating to a different RAID level or stripe size (Migrate RAID/Stripe Size) ” on page 60.)
• Extend the storage capacity of an existing logical drive on the array. ((For more information, see
“ Extending a logical drive (Extend Logical Drive) ” on page 60.)
To expand the capacity of an array:
1. Ensure that a known, good backup of the array is available.
2. Verify that the Expand Priority is set to Medium or High. (For more information, see
“ Changing global settings (Storage System Settings) ” on page 61.)
3. Select Array > Expand Array.
NOTE:
The Expand Array task is available only if unassigned physical hard drives are present in
the storage system. To be added to an array, the hard drive must be of similar type (SATA
or SCSI), processing ability, and size as the hard drives already included in the array.
4. Select the physical hard drives to add to the array.
Extending a logical drive (Extend Logical Drive)
If unused space is available in an array, you can use this task to increase the storage capacity of an
existing logical drive on that array.
NOTE:
The Extend Logical Drive task is listed only if unused space is present in the logical drive's array. To
create unused, available space in the array:
• Expand the array. (For more information, see “ Expanding an array (Expand Array) ” on page 59.)
• Delete a different logical drive on that array to release that space for use. (For more information, see
“ Deleting a component (Delete) ” on page 63.)
To extend the capacity of a logical drive:
1. Ensure that a known, good backup of the array is available.
2. Verify that the Expand Priority is set to Medium or High. (For more information, see
“ Changing global settings (Storage System Settings) ” on page 61.)
3. Select Logical Drive > Extend Logical Drive.
4. Enter the new size of the logical drive.
Migrating to a different RAID level or stripe size (Migrate RAID/Stripe Size)
1. Ensure that a known, good backup of the logical drive is available.
2. Verify that the Rebuild Priority is set to Medium or High. (For more information, see
“ Changing global settings (Storage System Settings) ” on page 61.)
