SerialSCSI-00 (sasd) B.11.31.0812 Mass Storage Driver Release Notes

5 Recommendations

This section provides recommendations for highest performance and reliability.

• Updating Physical Disk Firmware

Consider the following when you use sasmgr(1M) to update the firmware of physical disks

that are part of a RAID volume attached to an HP 8 Internal Port SAS Controller:

— If you are updating the firmware on two or more disks that are part of a RAID volume,

do not issue multiple commands to download simultaneously.

— If the disk firmware download to a disk that is part of a RAID volume fails or is

terminated, reset the controller using the sasmgr(1M) reset command:

sasmgr -f reset -D /dev/sasdX

(Replace X with the instance of the SAS controller.)

• Swapping Spare Disks

Consider the following when you swap physical disks in a RAID volume controlled by an

HP 8 Internal Port SAS Controller:

— Before swapping a spare disk, delete it first using sasmgr(1M):

sasmgr delete -D /dev/sasdX -q raid -q spare

(Replace X with the instance of the SAS controller.)

After the new disk is installed, use sasmgr(1M) to configure the new disk as spare:

sasmgr add -D /dev/sasdX -q raid -q spare -q enc_bay=<enc>:<bay>

(Replace X with the instance of the SAS controller and <enc>:<bay> with the location

of the disk to be configured as spare.)

— By default, RAID volumes are created with Auto-Configure enabled. If you swap a

physical disk that is part of a RAID volume, a resync begins and data on the new disk

is lost. Do not insert a replacement disk unless you are sure that existing data was

backed up.
