Problems with legato backup

[gjrono]

Hi!

Had problems during my backup during the night.

Backup started nice, but suddenly at one specific time, the backup started retry every server in my group. During a time of app 5 min. All my 5 retries was used, causing the backup to abort.

Anyone have any expirience, is this caused by network problem.

See clip of messages for one of the servers below, all 6 servers got the same messages during this short periode of time.

NetWorker Savegroup: (alert) DBFull completed, 6 client(s) (Client1, Client1, client3, client4, client5, client6 Failed)
Start time: Mon Jul 12 00:15:01 2004
End time: Mon Jul 12 07:21:19 2004

What is the inactivity timeout value for group DBFull?

 

[605]

Is the Removable Storage Manager Service disabled?

 

[gjrono]

Hello!

Thanks for the answers, and sorry for late reply

1. The timeout for this group is 80 minutes
2. The Removable Storage Manager Service is running.

What does the Removable Storage manager service do?

I think iv located the problem. First i'l replace the SDLT tapedevice, i think its defective. And il also change Storage Node to another server.

Disable RSM first! This MS service is usually not needed and is causing more problems than you may think.

The issue is that NW may even work 'for a while' but will then cause unpredictable errors. Once this is suppressed you should monitor your system for other potential problems. But eliminate the known troublemakers first.

Hello again!

And thanks for the answare again.

Today my backup went fine. Had a hp technician here changing the defective tape device.

I'l try to stop the Removable Storage service.

Only one more question, we use dynamic drive sharing. Does this mean i must stop/disable the Removable Storage service on each of the servers.

And to be realy shure, it is the Removalbe Storage service

Thansk again

Yes, of course you mist disable the RSM service on all computers which access your backup server.

 

[DavinaTreiber]

You don't need to disable RSM on all clients, just the servers and storage nodes.

 

[605]

Sure, that's correct. Of course you only have to do this where the BU hardware is attached.

Hi Again!

Legato Backup problems again.

My backup have run nicely for a couple of months now, but suddenly for 2 weeks ago something has went wrong again. This time it has to do with disabling the tapedrives. (Legato sets tapedrive to Service Mode)

It seems that when a tape is full and it is going to be ejected something is going wrong.

This doesnt happen all the time, it has happend 5 times the last 2 weeks and for 2 of my tapedrives

We have a Compaq 9000 series library with 4 SDLT tapedrives. Tapes in SAN.

I have added some lines from the messages log from yesterday. Anyone who know whats causing this. Can it be windows update?? Or hardware problem maybe.

As you can see, this has noting to do with the old problem -it looks more like a hardware problem with the jukebox and/or a media problem.

Please do not mix up issues.
