HP Smart Array 6400 Series Controllers Support Guide, September 2007

NOTE: When RAID 1 is configured on two physical disks, the saconfig /dev/cissX
command output displays the RAID level as 1+0.
Deleting a Logical Drive
Use the command saconfig /dev/cissX -D <Logical drive #> to delete a logical drive
that has been configured on a Smart Array Controller
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 will be lost when the saconfig /dev/cissX -D <Logical drive #> command
is entered.
NOTE: Deleting a logical drive from an array that contains multiple drives can leave “gaps”
within the array. To prevent gaps, logical drives should be deleted from an array in the reverse
of the order in which they were created. For example, if LD#0, LD#1, and LD#2 were sequentially
created in an array, LD#2 should be deleted first, LD#1 should be deleted second, and LD#0
should be deleted last.
Clearing the Logical Drive Configuration
Use the saconfig /dev/cissX -D all command to clear all of the logical drives that have
been configured from the physical disks attached to a Smart Array Controller. For example:
# saconfig /dev/ciss7 -D all
Are you sure you want to clear configuration on
SmartArray RAID controller /dev/ciss7? (y/[n]): y
Logical drive 0 deleted
Logical drive 1 deleted
Configuration cleared
CAUTION: All of the data on the logical drives and the physical disks connected to the specified
Smart Array Controller will be lost when the saconfig /dev/cissX -D all command is
entered.
Adding a Spare Disk
Use the saconfig /dev/cissX -A <Logical drive #> -s <Channel:Target>
command to add a spare physical disk to an existing logical drive. For example:
# saconfig /dev/ciss7 -A 0 -s 1:3
Spare drive 1:3 added to Logical drive 0
You can add multiple spare physical disks to a logical drive, depending on the number of physical
disks in the array that are not in use.
Deleting a Spare Disk
Use the saconfig /dev/cissX -D <Logical Drive #> -s <Channel:Target>
command to delete a spare physical disk from an existing logical drive. For example:
# saconfig /dev/ciss7 -D 0 -s 1:3
Spare drive 1:3 deleted from Logical drive 0
