SolutionDepending on your OS version you must use hwmgr (5.x) or file /dev/rz* (4.x) to get the device behind the adress.
If you are lost use the "man"-page of each command.

Re: How to find out the disk location in array
hwmgr -show scsi -bus 3 -target 2 -lun 0
If on 4.x systems, I think you could compute it like this,
rz[a-f](bus#)*(target#)+target# where a,b,c,..f (lun 0,1,2,3. .7)
and I guesss it would be,
rz26
pls. let me know if you have questions.

Re: How to find out the disk location in array
The error log entry is from the Unix side of the house. You suggest that it is mapped onto a storage controller. Lun 0 would then be the first 'unit' on the controller living on bus 3 at scsi 2. You can verify this with hwmgr and find the disk name for it. Please specify your Tru64 version and/or some storage controller details to allow us to help better.
Anyway, next step, either with hsxterm(5) or with the storage console you can use 'show d0' to find out what it is mapped onto. This can be a direct disk, or a raid/stripe set. The disk(s) on the controller will have similar bus-target-lun names but that are completely independend from the OS device.
You can use 'locate d0' with hsxterm or storage console to flash the yellow lights on the actuall disk.
Another crude but effective way to locate disks is to issue a 'dd if=os-disk-name of=/dev/null' and if the disk still works a little bit this will give you green activity lights.
I have made some scripts to map os-devices to controller units to controller devices, but thos are relatively version and controller dependend (hsz/hsg/(no)command-lun/...). I can dig those up if interested but they likely need changes.
Good luck,
Hein.

Re: How to find out the disk location in array
next time only assign 10 Pts once and not for every answer or correction! Btw. if someone repeats an answer from previously poster why giving him the same points?
Please read the itrc forum rules next time, specially information about assigning "points"

Re: How to find out the disk location in array
I have overlooked that you need to check your storage system anyway, because DISK10000 has failed.
