I use Omniback configured according to Administrator's Guide.
Randomly but often a tape remains blocked in a drive and I need to cycle power and unload drive manually.
Where can I indagate for the cause of this problem?
Thanks in advance

Re: DLT and SAN
Do you have SCSI Reserve/Release DISABLED for both the robotics and the drive?
Do you have direct library access turned OFF?
Make sure your hosts have the kernel parameter st_ats_enabled set to zero

Re: DLT and SAN
Yes, SCSI Reserve/Release is disabled (and checkbox is grayed and not selectable) everywhere.
Direct library access is turned everywhere.
Kernel parameter st_ats_enabled is set to zero for every host.
Other suggestion?
Need I to check with HP support the EMS error?
Thanks again

SolutionYou *need* to have EMS turned off
for SCSI on tape drives or you
will have big problems. Another
very important thing is to make
sure that you the very *latest*
firmware installed. There has
been some major problems fixed
in regards to tape drives and
FC. Look at the firmware issues
from end to end.
