In this example, eight physical disks are attached to the Smart Array Controller (
/dev/ciss5
).
Configuring a logical drive
To configure a logical drive, use the following command:
saconfig /dev/cissX -R
<RAID level>
[-S
<Stripe size (KB)>
] -p
<physical
drive id>
[-p
<physical drive id>
... ]
[-s
<physical drive id>
] [-c
<capacity
(GB)>
]
Where:
-R
<RAID level>
The RAID level to be configured on the logical drive. For
information on the RAID levels supported by each Smart
Array controller, see
“Supported RAID modes, by
controller” (page 26)
.
[-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 is 128 KB if the
-S
option is not used.
For RAID 5, 50, ADG, and 60, the options are:
•
8 KB
•
16 KB
•
32 KB
•
64 KB
The default stripe size is 16 KB if the
-S
option is not used.
-p
<physical drive id>
[-p
<physical drive id>
...]
The physical disks included in the logical drive. Each
physical disk is identified by Connector/Enclosure/Bay or
WWID. Obtain this information from the output of the
saconfig
<dev_file>
command, as described in
52
