Does anyone have any experience turning off SCSI Reserve / Release in NBU 6.0 with NDMP SSO? I have 24 LTO-3 drives sharing between a local Linux host (NBU 6.0MP4) and 11 Celerra data movers, which are configured to *use* SCSI reserve / release by default. If a data mover panics and fails over while holding some SCSI reservations, those particular drives become useless to me (SCSI reservation conflicts on my host) until I reboot the robot and the host. Running a reset from Netbackup fails, as it thinks the drive is in use, and if I run it from the command line on the generic device, it clears up the reservation conflict, but the local device paths are still hosed.
Do I still need SCSI Reserve / Release if Netbackup is the drive broker in this case? Looking through some of the Celerra documentation, it says to disable reserve / release if doing dynamic drive sharing in ARCServe and CommVault, I'm wondering if NBU would be similar? EMC and the robot vendor both say to turn SCSI reserve / release off, Veritas says to leave it on; anyone out there with any experience with these issues? thanks. _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
