Re: File system backup fail, tape media mark as poor
What out for RSM polling getting in the way (make sure RSM is turned off if you're running Windows). Watch out for any other hosts perhaps running HP-SIM agents.
If you're on Windows, you can find some of these by running Library and Tape Tools and pull a support ticket. Look at the system config info at the top. Also look at the drive health info lower down. Have a look through the ticket in general for any warnings.
Note L&TT also runs on non-Windows but the system checks are limited in this case.
With L&TT you can verify the health of the drive with the drive assessment test and also use the device performance test to model backups without the app in the way. Select full tape in the options.
If you need any help checking the support ticket then post it here and we'll take a look.
Good luck. Richard.

Re: File system backup fail, tape media mark as poor
I am connected to SAN switches, and I am using windows cell manager,
I discovered that RSM is not disabled on Cell manger server ,I have disabled using registry editor.
do I need to disable it on all DP client machines?
I hope that will help,
Thanks

SolutionRSM polls for any storage and generally disrupts any backups that are going on. If your server can see the tape drive then RSM should be turned off.
On a SAN that can be a real pain! If you're not carefully zoned you could have RSM getting in the way from almost any server.
The LTT ticket will tell you if RSM is off (system config at the top).

Re: File system backup fail, tape media mark as poor
RSM is a Windows service so doesn't apply to HP-UX. Watch out for polling generally but RSM is the worst. Good zone will reduce polling (especially the sort that detects devices and then polls everything it finds!).
New feature in LTT 4.5 (out Nov 12 ish) will check to see if an LTO drive is being *over* polled by checking its own logs. Output will be under device analysis. Have to wait for that one, sorry.
