DB13 - Onlinebackup Tape Failure

[Former Member]

Hi there,

When I look in the detailed log for a recent online backup I see the following:

BR0388I Mounting volume EZI701S1 in device /dev/rmt/1cb ...
BR0280I BRBACKUP time stamp: 2012-09-11 21.16.39

BR0280I BRBACKUP time stamp: 2012-09-11 21.16.40
BR0054I BRBACKUP terminated with errors

Can anyone give me an idea as to what is going on? 

It says that the tape drive may be offline but I am able to move tapes in and out of this drive

so how can this be?

Any ideas/suggestions much appreciated

Thanks

Andy

Hi Andy,

You have initialized your backup for:

BR0388I Mounting volume EZI701S1 in device /dev/rmt/1cb

where as utility is trying to rewind tape at location

/dev/rmt/1cn

Is it correct?

Thanks,

Hi Andy,

please provide output from following command performed as orapr1 user on host sappr6

mt -f /dev/rmt/1cb status

Hi Andy,

What is the exact comand being used for the backup?

Is it possible that the backup takes up more space than is available and a second tape is needed?

The problem could be related to the wrong setting of tape related
parameters in init<sid>.sap:

tape_size                      ???
tape_address                   /dev/rmt/1cn
tape_address_rew               /dev/rmt/1cb

Please refer to Note 8707 and set it accordingly.

hope this helps.

Hi Paul,

Many thanks for replying. The exact command is:

brbackup -u / -jid ALLOG20111228211500 -c force -t online -m all -p initDV1.sap -v EZI701S1 -a -c force -p initDV1.sap -cds

Hi Andy,

I am not sure what is causing the error.

What is the size of the db compared to the tape capacity?

Are you using the latest brtools version?

Hi Paul,

I don't think it is anything to do with tape capacity. The tape drive

thinks it is 'offline' for some reason.

I'll search the internet to see if I can find anything about testing the

tapedrive for being online or how to get the drive back online.

Thanks anyway

Andy
