Device problems

Coolmar — Tue, 11 Apr 2006 08:20:42 GMT

Hi,
We disconnected a tape device a while ago and have been getting the following messages in the syslog ever since:

Apr 11 06:50:16 pfreg26 vmunix: SCSI: Unexpected Disconnect -- lbolt: 127064, dev: cb07e002, io_id: 7000068

Apr 11 06:50:17 pfreg26 vmunix: SCSI: Unexpected Disconnect -- lbolt: 127070, dev: cb07f002, io_id: 7000069

An ioscan did have the tape device with NO_HW, however after a reboot that disappeared but the syslog messages didn't. How can I get rid of these messages?

Thanks,
SD

I think you need to remove the special file.

rmsf /dev/rmt/xxxxx

Here is the ioscan - we have two tape drives that we use...and they show up in the ioscan (see below). So do I remove with rmsf everything that is not listed in the ioscan?

Sally,

Do not remove anthing other than the tape drive that you no longer use. I am assuming that it is not one of the two that remain in the ioscan?

Regards,

JASH

JASH: No, it does not remain in the ioscan. The two in the ioscan are the ones that I want to keep.

JASH_2 — Tue, 11 Apr 2006 09:05:27 GMT

Sally,

Ok, looking at the amount of redundant tape drive special files you have, it may well be worth removing the ones not on ioscan. Most of them date to 2004, or before, so removing them would not be the problem I first panicked about!

Regards,

JASH

Re: Device problems

Coolmar — Tue, 11 Apr 2006 09:08:42 GMT

Thanks JASH...can I jsut delete them, or do I have to rmsf each and every file? Do I include those C18d0txxx files as well?

Re: Device problems

TwoProc — Tue, 11 Apr 2006 09:10:30 GMT

Sally, rmsf the ones you don't want - so that you don't get polling errors, it's cleaner than just deleting the special files with "rm".

Re: Device problems

Pete Randall — Tue, 11 Apr 2006 09:15:55 GMT

Sally,

You can use rmsf with the -H option to specify a hardware path or you can specify the device file itself, like this:

rmsf /dev/rmt/[0123]*

Just make sure you get the right ones!

Pete

JASH_2 — Tue, 11 Apr 2006 09:22:06 GMT

Sally,

Might be worth using your ls /dev/rmt/* to create a file of the ones you need to delete, then do a "for i in...." script. It would be quicker, just make sure you take out the ones you want to keep.

Regards,

JASH

Thanks! Should I keep this file:

Sally,

I would!
