Re: Disk Errors

The four tools involved here (depending on the particular I/O path and OpenVMS versions are:

The add-on tools:

DIAGNOSE (DECevent)

HP SEA / CA / WEBES / WEBEM

These tools are available here:

http://h18000.www1.hp.com/support/svctools/

And the integrated error-related tools:

ANALYZE/ERROR (older versions)

ANALYZE/ERROR/ELV (V7.3-2 and later)

Unfortunately, this area can be somewhat a mixed bag, and you can end up needing two or more of these tools installed, depending on the particular devices and errors involved.

FWIW: If I had a hard disk that was showing errors, I'd be getting the data off the disk and getting set to swap it for a spare. Modern disks tend to have failure modes that make it likely that disks reporting errors are approaching full failure.

It is also my experience that the time and effort and I/O involved in reformatting a disk showing errors -- reformatting is an old solution, and one that hasn't really worked all that well starting with the RA8x series and later -- will probably be wasted.

The I/O involved in off-loading can (also) push the disk into full failure, as can the load of unloading and formatting and reloading.

Disks that are reporting errors should be assumed to be failing, and not really worth the effort to try to "repair".

Re: Disk Errors

Hi Robert,

You can see by the command on the system

$> show device
For example:
$> show device $1$DGA1123:

or simply you can see on all system devices errors by command

$> show error


Please check I hope you got very simple answer.
I love VMS
