Errors on SYSTEM disk

Chaim Budnick — Tue, 01 Feb 2005 00:19:18 GMT

In the past two days there have been 4 errors generated on the SYSTEM disk.

I tried runing ana/err:

ALFMEN> ana/err
Error Log Report Generator Version V7.1

%ERF-F-CEHFND, New header format found. Install DECevent and run conversion util
ity

What can I do at this point to further investigate the nature of these errors?

Thanks,

Chaim

Chaim,

As the message says "install DECevent".
Then you can use the DIAGNOSE command to look
at the errors.

Dave.

If you can't find DECevent on the distribution
CDs, you can get the latest from

In checking the daily BACKUP routines I have just noticed several errors on a particular file.

I then issued a manual BACKUP on the file, and following are the results:

The error count BEFORE this command was 4!

ALFMEN> back SHARP7_1229.DAT a.a
ALFMEN::SYSTEM 08:15:20 BACKUP CPU=00:00:04.97 PF=1515 IO=10238 MEM=442

Thanks,

It seems, the disk is going bad. I would forget the file and look for a valid backup and
a replacement disk.

Hi All,

Just a question for the above question...
Is there any way we can end up this error showing on sho err command....like below

ALFMEN> sho err
Device Error Count
ALFMEN$DKA0: 7

Cheers,
Himanshu

In VMS 7.3-2 there is been introduced to reset your error and operatoin counts.

You can reset the error count with
$ SET DEVICE/RESET=(ERROR_COUNT, OPERATION_COUNT)
or just one of the two.

Hi Anton,

Sorry but I have the following version

OpenVMS V6.2-1H3

I dont think so its supported on lower versions as per HP...

"The system reboot is the only supported approach, but it is obviously undesirable in various situations---there is presently no supported mechanism to reset error counts once the error(s) have been logged."

Thanx anyway,
Cheers,
Himanshu

Chaim, delete those files and bad block replacement will take place. Do a ANAL/DISK/READ to check for others. Depending in your environment you may just accept part of the disk has gone bad (bad block replacement should ensure you don't use that part of the disk again) and continue to use the disk watching for new errors, or you may look to replace the disk while the old one still works.

Some alphaservers such as the DS20e require the compaq analyze tool instead of the DECevent tool.

Chaim, It's possible to use anal/error/elv in VMS 7.3 (I don't know if it exists in VMS 7.1) and use translate command to see
SYS$SYSROOT:[SYSERR]ERRLOG.SYS
About disk problems, Have you use anal/disk/repair utility with the object of repair bad files in disks?.
