Netbackup Guru’s,
We have a hot database backup policy configured to backup an
oracle database on two separate unix hosts. Both hosts backup using the
same schedules and the exact same RMAN backup script. One host completes
successfully, the other started giving us the following error after a recent
clone.
RMAN-03009: failure of backup command on ch02 channel at
03/24/2011 07:20:54
ORA-27192: skgfcls: sbtclose2 returned error - failed to
close file
ORA-19511: Error received from media manager layer, error
text:
Failed to process backup file <bk_1305_1_746591618>
ORA-19502: write error on file
"bk_1305_1_746591618", block number 9901857 (bloc
k size=8192)
ORA-27030: skgfwrt: sbtwrite2 returned error
ORA-19511: Error received from media manager layer, error
text:
VxBSASendData: Failed with error:
The block mentioned here is one of 2 that it seems to be
having issues with (the other is 9901825) but I’m at a loss as to where I
should be looking to tie in the block number and RMAN backup piece information
in order to find out what file the bad block is located in.
The result from a netbackup perspective is that the hot
backup never completes on the failing host. It just sits there until it
eventually times out or we kill it.
As far as we can tell, there are no differences in the RMAN
or netbackup configurations which points to a data error of some kind. I’d
really appreciate any guidance on the best way to troubleshoot this.
Thanks in advance,
