Hi,
I recently upraded to Netbackup 4.5 Datacenter on our Solaris server. We
currently have three old Exabyte EZ17 autoloaders connected up to the system.
Since I activated the scheduals, I keep running into a problem where during the
backups the tape drives error out and they get downed. As a result, I only get
a
few of my servers backed up, while the rest fail because none of the tape
drives
are available. I've cleaned the tape drives, and that was not the problem. The
tape is brand new. Here are some of the error messages I see in the
/var/adm/messages file:
Dec 19 19:05:49 hgsun27 scsi: [ID 243001 kern.info]
/sbus@1f,0/QLGC,isp@3,10000/st@0,0 (st21):

(NetBackup) has DOWN'ed drive index 2, see application error log for further
information
This is what I see in the bptm log file:
19:08:20.547 [1109] <2> log_media_error: successfully wrote to error file -

I see in these error messages that there seems to be a problem with the block
size. Also, for the backups that do run before the drives get downed, they take
a lot longer than they use to. I have a full backup that I started three days
ago for a test system.. it's still running! Normally, I can do a full backup of
all of my 25 systems within 7 hours. Nothing has changed hardware or network
wise. What can I do to fix this problem?
Thanks in advance for any help!
