SmartArray RAID Controller.

With no other options,

saconfig displays size and status for all physical drives

and RAID level, size, and status for all logical drives.

With the

-N option, saconfig displays size and status for all physical drives and

RAID level, size, and status for all logical drives. But the persistent device ﬁles (see

intro (7)) will be displayed as against legacy device ﬁles in the absence of this

option.

-R <RAID_level> To create a logical drive with the speciﬁed RAID level. The supported RAID levels

are 0, 1, 1+0, 5, 50, 60, and ADG.

To determine the supported RAID level for the SmartArray RAID controller, use the

sautil -vpd command. The lowest logical drive number not already in use will

be given to the newly created logical drive, starting from 0.

To determine the hardware path and device ﬁle for the logical drive, use the

ios-

can -kfn command. The logical drives are displayed in the same order as in the

saconfig output.

RAID 1+0 logical drive requires even number of physical drives (minimum of 2). To

achieve optimal fault tolerance, it is best to specify the same number of physical

drives per channel if possible when creating a RAID 1+0 logical drive. This ensures

the physical drives in each mirrored pairs would be on different channels.

-S <stripe_size> To specify the stripe size for the logical drive to be created. The supported stripe

sizes are 8, 16, 32, 64, 128, and 256 (KB). 128 and 256 stripe sizes are not available

for RAID 5 or ADG logical drive. If this option is not used to specify the stripe size,

default stripe size will be used to create the logical drive. For RAID 0 and 1+0 logi-

cal drive, the default size is 128. For RAID 5 and ADG logical drive, the default

size is 16.

-p <physical_drive_id>

To specify the SCSI physical disk. It can be represented as

<channel_id> :<target_id> (e.g., 4:12). Valid channel numbers are between 1 and

4. Valid target numbers are between 0 and 15.

To specify the SAS/SATA physical disk. It can be represented as either

:<enclosure> :<bay> (e.g., 2I:1:10) or <wwid> (e.g.,

0x500000e010f16432).

-s <physical_drive_id>

To specify a spare drive to be included in the logical drive conﬁguration. Refer to

<physical_drive_id> of the

-p option.

-c <capacity> To specify the size in GB of a logical drive to be created.

-A <logical_drive_num>

To specify which logical drive to add spare drive to.

-e {low | medium | high}

To change the expand priority of controller to one of low, medium,orhigh. When

there are no logical drives, expand priority cannot be changed. When the

conﬁguration is cleared, or the last logical drive is deleted, the subsequent logical

drive creation will change the expand priority value of the controller to medium.

-r {low | medium | high}

To change the rebuild priority of controller to one of low, medium,orhigh. When

there are no logical drives, rebuild priority cannot be changed. When the

conﬁguration is cleared, or the last logical drive is deleted, the subsequent logical

drive creation will change the rebuild priority value of the controller to high.

-P {default | shortest | longest}

To change the path selection method by the controller ﬁrmware. If it is set to

default, ﬁrmware will select the Active path on its own. If the selection method is

set to shortest, ﬁrmware will select the shortest path as the Active Path. If the

path selection method is longest, ﬁrmware will select the longest path as the

Active Path. All multi path conﬁgurations are Active-Standby conﬁgurations.
