HP Smart Array 6400 Series Controllers Support Guide, September 2007

Displaying the Smart Array 6400 Series Controller Configuration
To display the physical disks connected to a Smart Array Controller and any configured logical
drives and spare drives, use the saconfig /dev/cissX command, where X represents the
device file number for the Smart Array Controller.
The channel, SCSI ID, size, and status of each physical disk attached to the Smart Array Controller
is included in the saconfig /dev/cissX output. If any logical drives have been configured
on the Smart Array Controller, a detailed description of those drives will be displayed:
# saconfig /dev/ciss7
******************** SmartArray RAID Controller /dev/ciss7 ********************

External 2 1 18.2 GB UNASSIGNED
External 2 5 18.2 GB UNASSIGNED
External 2 8 18.2 GB UNASSIGNED
In this example, 15 physical disks are attached to the Smart Array Controller (/dev/ciss7). No
logical drives are configured and no spare drives are configured.
Configuring a Logical Drive
To configure a logical drive, use the command:
saconfig /dev/cissX -R <RAID level> [-S <Stripe size (KB)>] [-s
<Channel:Target>] -p <Channel:Target> [-p <Channel:Target> ... ]
Where:
-R <RAID level>
The RAID level to be configured on the logical drive.
[-S <Stripe size (KB)>]
The stripe size (KB) to be configured on the logical drive.
For RAID 0, 1, and 1+0, the options are:
• 8 KB
• 16 KB
• 32 KB
• 64 KB
• 128 KB
• 256 KB
The default stripe size is128 KB if the -S option is not used.
For RAID 5 and ADG, the options are:
• 8 KB
• 16 KB
• 32 KB
• 64 KB
The default stripe size will be 16 KB if the -S option is not
used.
