I have a HP 8x Autoloader connected to the server, I am running Symantec Backup Exec 12.  For some reason about a week ago my backups starting to fail.  Backup Exec sees the device and I am able to inventory; scan and format tapes.  Once I do a format and restart the backup the backups begin to fail and the tape are labled "Not appendable (End marker unreadable)".  I have switched tapes, tape drive, scsi terminator.  Not sure what else to do.  I ran HP StorageWorks tape tools and everything test good, the tapes are listed correctly, firmware is up to date.

This means the job is stopping abruptly for some reason. It could be the job engine service stopping/restarting or a SCSI timeout, etc., basically anything that stops the flow of data to the tapes.

Since there isn't a marker on the tape that tells future jobs where the past jobs stopped, the tapes are marked as not appendable.  Is there anything helpful in event viewer or the job logs?

A good post to look at...

Here is one of the errors that I have found in event viewer.
Backup Exec Alert: LiveUpdate Error
(Server: "TPGPHLSQL01") Update HOTFIX 355600 failed to install.  Review the Backup Exec installation log for more information.

I have also noticed that the green light on the scsi termitor is not lite, when I unplugged the scsi cable the light turned green, I plugged cable back in and the light went out.  I reset the terminator and the scsi card with no differnt results.

Here's a good SCSI reference...

Also, have a look here on page 28, and also take a gander at the troubleshooting section.

Try powering off the server and tape drive and disconnect everything.  Then reconnect everything and verify proper termination.  Then power the tape drive back on and wait until it fully initializes.  Afterwards, power the server up.

Live Update will fail if you have jobs running during this time.  You should disable Live Update and manually run these during off hours, unless you have a regularly scheduled maintenance window where backups NEVER run.  The key here is to run Live Updates when backup jobs are not running, and ensure that Live Updates never run during backup windows.

Your solution worked to a t, I should have did that after the HP tech was done replacing the scsi card.
