Tru64 command for disk recongnizing in a disk array

[Shehan]

Hi All
Our system Alpha ES40 with running tru64 unix. Also it has been attached MA8000 disk shelves. There is a failed disk in a mirror set. Now I need to recognize good disk in that mirror set using a Tyr64 command.

Anybody knows any command in tyr64 to identify disk in disk array.

The mirror is done via LSM or via hardware?

¿What is your tru64 version? ¿4 or 5?

[Shehan]

Mirror has done from hardware and tru64 version is 5

If mirror is done via hardware, you need an utility to check the status of the devices.

To physically locate the disk you can use
hwmgr -flash light
and remove/replace the failed disk.
-------------
-flash light
Use this option to flash the display light (LED) on a SCSI disk device
for a default time period of 30 seconds. Note that this operation may
not work on all devices, and you may have to open a cover to access the
light on some systems, particularly where the disk is installed in an
internal bay.

-dsf device-special-filename
Specifies a device by its special filename such as /dev/disk/dsk4.

-bus scsi-bus
Specifies the device(s) on the given SCSI bus number.

-target scsi-target
Specifies the device(s) at the given SCSI target number.

-lun scsi-lun
Specifies the device at the given logical unit number.

-seconds N
Specifies a duration of N seconds for the light to flash. The
default is 30.

-nopause
Specifies no pauses between flashes.

Hope this help,

To locate individual disk
bring the system down to SRM console
give "show config" & check the name of the controler. & go to the configuration program for the controller by giving run command.
When working on a raidset or on a individual disk the respective disk LED's will blinks.

thru OS, as kapil told thru "hwmgr" with "flash" is the best option to locate disk.

if mirror is done by msa/hsg80 you may try hszterm to connect to the controller
or connect a serial terminal (emulator) to this controller.
from there use
show mirrorsets
show storagesets
show failedset
to locate the components
