/var/adm/messages - Error Messages

Hi,

Running Tru64 Unix 5.1 with Patch Kit 6.

I receive the following messages

Nov 20 16:14:16 Nodename vmunix: device_translate: device cannot be translated 'SCSI3 1 5 0 0 0 0 0 PN: WWID:01000010:6000-1fe1-0008-a0b0-0009-0210-3294-0038'

I have all the disks in SAN connected through HSG80 controller and the error message looks like some kind of intermittent issue with one of the SCSI HDDs.

Can anyone explain more please

Thanks in advance

Re: /var/adm/messages - Error Messages


Is the device reported in the "hwmgr sho scsi -full" output ?

What is the result of "hwmgr get attrib -id xyz" ?

Any entries in binary.errlog about this device ?

Johan.

Hi,

Thanks for your quick response.

The device in question is dsk8 ( which is one of the LSM boot disk submirror - dsk4 and dsk8 plexed and mirrrored to form the root, usr var and swap volumes ).

The output of the various commands are attached.

Please let me know what all to look for and how to rectify this condition

Thanks again.

Hi,

do you have decevent installed? It gives more information from the binary errorlog.

Re: /var/adm/messages - Error Messages

Could be a problem with LUN 0, try to use another LUN for this disk (by not using D0 in HSG config). LUN 0 has a special meaning (command console interface) depending on the HSG controller settings and this could interfere with storage works agents accessing the HSG controller.

Re: /var/adm/messages - Error Messages

Looks like the device reporting the error is LUN 4 in any case...

One thing I did notice from the error log is that some entries come from an HSG running 8.7F and some running 8.7S. Do you have more than one pair of HSG80s?

If you're in a situation with an HSG80 pair running two different versions of ACS that's a very bad thing.

Also, I find that wsea (System Event Analyzer) from the WEBES kit on the Associated Products CD does a better job of interpreting HSG events that DECEVENT.

Re: /var/adm/messages - Error Messages

I believe dsk8 is in error too. According the hwmgr output sent dsk8 = Bus 1 Target 0 Lun 0.
So the device in binary.errlog Lun 4 must be another ?

Re: /var/adm/messages - Error Messages

Hi All,

Thanks for your response..

Just to add...I have been having these messages only during the weekly syscheck run ( every saturday evening ), otherwise i don't get any such events logged.

If that makes any sense.

Re: /var/adm/messages - Error Messages

I have seen cases where running sys_check causes spurious HSx "events." I've never seen these correlate to any real errors so I wouldn't worry too much about them.

You didn't answer the question about how many HSG80 pairs you have though. If you're really running different ACS versions in the two halves of a controller pair I would be very worried - and kind of surprised it even works!

Re: /var/adm/messages - Error Messages

sys_check is accessing the HSG80 command console LUN to get the configuration data. As mentioned before this may disturb the I/O for a disk residing on LUN 0. This is possibly the reason for the error messages. But you should take into consideration also all other hints.
