Working with Disks

Blinking a Disk Light

The disk blink command causes a disk drive’s activity light to

flash or stop flashing. This feature allows you to identify the

physical drive that corresponds to a disk displayed by the disk

list command. Before executing the disk blink command, use

the disk list command to display the SCSI device ID of the disk

to be blinked.

To blink a disk drive’s activity light, use the disk blink

command, as in the following example. In the following example,

the disk drive light on device (2,2,0) will blink for five (5) seconds.

HPN0> disk blink (2,2,0) 5

Executing: disk blink (CHANNEL=2,ID=2,LUN=0) 5

To stop a disk from blinking, use the disk blink command, as in

the following example. In the example, the disk drive light on device

(2,2,0) is set to blink for 0 (zero) seconds, which stops the blinking of

the disk drive light.

HPN0> disk blink (2,2,0) 0

Executing: disk blink (CHANNEL=2,ID=2,LUN=0) 5

Working with S.M.A.R.T. Disks

The acronym S.M.A.R.T. stands for Self-Monitoring, Analysis, and

Reporting Technology. This technology is an industry standard for

hard drives that monitors a variety of disk parameters, such as the

rate of read-write errors. In addition, S.M.A.R.T. can send an alert to

system administrators about potential problems caused by disk

errors.

The CLI supports disks that incorporate S.M.A.R.T. technology. The

CLI allows you to do the following:

■ Display the S.M.A.R.T. attributes

■ Set the S.M.A.R.T. attributes

The following sections list and describe the S.M.A.R.T. attributes.
