Deleting a logical drive To delete a logical drive that has been configured on a Smart Array Controller, use the command saconfig /dev/cissX -D . The following example deletes logical drive 0 from the Smart Array Controller with the device filename ciss7: # saconfig /dev/ciss7 -D 0 Are you sure you want to delete logical drive 0 on SmartArray RAID controller /dev/ciss7? (y/[n]): y Logical drive 0 deleted WARNING! All data on the specified logical drive and the physical disks included in that logical drive is lost when you enter the saconfig /dev/cissX -D command. Deleting logical drives when multiple logical drives share physical disks To avoid fragmentation when multiple logical drives share one or more physical disks, you must delete the drives in reverse order of the logical drive number, from highest to lowest. To determine the drive numbers, use the saconfig /dev/cissX command. Example 3-3 shows the saconfig /dev/cissX command output for three logical drives that share one physical disk: 54 Configuration

Deleting a logical drive
To delete a logical drive that has been configured on a Smart Array Controller, use the command
saconfig /dev/ciss
X
-D
<Logical drive #>
.
The following example deletes logical drive 0 from the Smart Array Controller with the device
filename
ciss7
:
#
saconfig /dev/ciss7 -D 0
Are you sure you want to delete logical drive 0 on
SmartArray RAID controller /dev/ciss7? (y/[n]):
y
Logical drive 0 deleted
WARNING!
All data on the specified logical drive and the physical disks included in that
logical drive is lost when you enter the
saconfig /dev/cissX -D
<Logical drive #>
command.
Deleting logical drives when multiple logical drives share physical disks
To avoid fragmentation when multiple logical drives share one or more physical disks, you must
delete the drives in reverse order of the logical drive number, from highest to lowest.
To determine the drive numbers, use the
saconfig /dev/ciss
X
command.
Example 3-3
shows the
saconfig /dev/ciss
X
command output for three logical drives that
share one physical disk:
