Disk Failure

[Jim Rogers_1]

I have a 9000 D370 and when I run ioscan, I have a drive with NO-HW on it. How do I determine which drive phisically it is to remove it and replace it?

Try to do an ioscan -funC disk and get its /dev/dsk/c#t#d.

Then use dd to light up the lights!

dd if=/dev/dsk/c#t#d# of=/dev/null

You will see the led/light on the drive going solid. This is the physicall drive.

Also do a /etc/diskinfo /dev/rdsk/c#t#d# and see if it has a problem.

Also try pvdisplay /dev/dsk/c#t#d# if it in use by lvm.

Typically, you will see a drive with the LED 'ON' all the time - that's the bad drive. The other, better way is to do an ioscan -fn | lp
and note the harware paths. The hardware path will look something like this:
10/12.5.0 - 5 is the SCSI ID. You need to find the drive with the SCSI ID setting of 5. Inside the cover off your D370 is a diagram which matches those hardware paths to a particular slot. The same information can be found in your system dicumentation. If you determine that it is one of the internal hot-plug drives, the SCSI ID's are numbers in this order (top to bottom) 5,8,9,10,11.

I found the disk as /dev/dsk/c3t2d0
with a HW id of 8/8.2.0

when I run the dd if=/dev/dsk/c3t2d0 of=/dev/null, the system never return to the prompt and none of the drive LED stay lit.

upon running diskinfo, I do not see any errors.

on pvdisplay, it has a PV Status of unavailable with about half of the Total PE in Stale PE

PATH 8/8.X on a D370 refers to the controller in HSC Slot 2. Your drive is the drive with SCSI ID 2 on this bus.
