SC10 Disk Identification

[Dan Powers]

Hello Everyone,

I have just inherited an L Class 2000 with an SC10. The SC10 is configured as split bus with mirroring. I didn't receive any docs/diagrams on the configuration. It has two bad disks and one unmounted disk. I'd like to visually id the problem disks in the array. I know XSTM has led flashing but you need the hp only license to unlock it. Does anyone know of any other way to flash the led's for the disks? I imagine with a bit of work I can id them but flashing the led's would be much faster.

Thanks,

Dan

Figure 13 on page 79 of the service guide will identify which disk is which.

I would go for a simple 'dd' command to flash the lights. Find out your disk device files from 'ioscan -fnC disk' commmand and then:

# dd if=/dev/dsk/cXtYdZ of=/dev/null

The lights will be continuously ON during reading. Also, try light flashing option on SAM.

I have a L class 2000 with a SC10 and simple mirroring.

ioscan -fnC disk.
will show you the devices.
and dd if=/dev/dsk/address /dev/null
will light up the desired drives.


If you are receiving errors or
ioscan doesn't show the device
you can dd the drive before and after to pinpoint drive.

Also the bottom right light on each disk is fault light (green ok) (amber not ok)
