identifying disks

[Ravinder Singh Gill]

If I want a HP engineer to remove particular disks ie c11t2d0 c11t3d0 c11t4d0 c11t5d0, how do I identify these to the engineer if I look after the server remotely?

One of the methods I've used is to run a dd against the disk and watch for the one with the activity light blinking:

dd if=/dev/rdsk/c11t4d0 of=/dev/null bs=1024k

Hi Ravi:

An old, classic way if the drives have any lights is to light them up with:

# dd if=/dev/rdsk/cXtYdZ of=/dev/null bs=64k

Hey;

The first way is to identify the hardware path:

ioscan -funC disk ${ctd} | awk '[print $3}'

Once that's done, if the engineer doesn't know how to ID which slot that's in, you should probably have a different engineer.

On most 11.11 systems, you can run

rad -q

to identify PCI slots and hardware addresses.

On 11.23 systems, it's olrad -q

The first way to try is of course using the dd command to light up the disks, but if the disks are well and truly dead and they are in a disk array, the lights will flash amber, giving the engineer an indication that their is a dead disk in the array.
