hi,

unless u have the hardware manual, there is another way u may try to locate the disk. run dd command where the disk light should be flashing all the time that the command is executed:

# dd if=/dev/rdsk/c1t6d0 of=/dev/null bs=512

hope it helps.

regards.

Unfortunately the old systems doesn't have hot plug disk. The physical location of the disk doesn't have meaning becuase each disk is recognised by it's SCSI id. You have to look in to the hardware manual for the disk and find out the jumper settings. c1t6d0 is the disk set to SCSI-ID 6 bus ext_bus 1.

You can also run dd if=/dev/dsk/c1t6d0 of=/dev/null and notice that disk will have continues activity.

If your disk is already failed, then only way is to check the Jumper settings!!

<(HP-PB slot number * 4) + module number> . = device path address

If you try to run the DD command on the failed disk it may hang. I recommend using the '&' at the end of the command the other responders sent to run the command in the background. If the disk is bad and you know it, try running the command on an adjacent disk. The command just lights the disk access LED so it is easier to locate. If you have Offline Diagnostics you can run Mapper several times and each time pull out a different disk until you find it. I am not sure what type of enclosure you have so this might not be practical (as is the case with the old 6000 units where 1-5 disks are mounted inside). Good Luck!
