Checking disk failure from the system

I have a disk failure w/c showing amber lights blinking, how can I check it from the system which particular disk is defective?

THanks.

Ronald,

you know the bus and unit umber of the disk from VMS (SHOW ERROR, DIAGNOSE...). Raid controllers and such often have a LOCATE function, which activates the LED on the disk to find it.
A simple apporoach is to just do some IO (ANA/DISK/READ) to the disk or its neighbors and check for the activity LED.

Another simple check is

$ show device d

will display disk drives, mount status and error count. Disks showing mount verify or offline won't be available.

If you don't have time to do it right, when will you have time to do it over? Reach me at first_name + "." + last_name at sysmanager net

Re: Checking disk failure from the system

Ronald,

Before we go any further: Which disk controller is the drive connected to?

If it is in some form of array, the problem may be covered by the the array transparently.

This is good news/bad news. The array may not show errors (at least at the OpenVMS level) until things get far worse.
