That one is then reserved, while the process waits for the other to become available, making sure the reserved drive is still available for use when the other resource becomes available. Happens to us all the time. I'd check 'q dr' and 'q path'. -- Met vriendelijke groeten, Remco Post SARA - Reken- en Netwerkdiensten http://www.sara.nl High Performance Computing Tel. +31 20 592 3000Fax. +31 20 668 3167 "I really didn't foresee the Internet.

I believe that the only quick fix is to restart the TSM server. A Reserve is a special device command to retain control of a tape drive or the like in an environment where the drive is shared by multiple hosts, over multiple open-close processing sequences. In AIX, this is accomplished at the driver level by issuing an ioctl() to perform an SIOC_RESERVE command. You can do 'SHow MP' and possibly 'SHow LIBrary' to verify this status and fully identify the drive at issue. I would check back in the Activity Log to determine what circumstances were involved in that drive becoming reserved, to try to possibly identify an issue with an operation sequence or allied software component which precipitates the condition, to avoid or correct it. Elevating the maintenance level of your TSM server may or may not alleviate the possibility of recurrence. Richard Sims

restore causing mount tape to status reserved?
TSM 5.1.6.5 on windows 2K server. When I run a simple restore, nothing that I haven't done a hundred times before, the restore hangs after a minute or two, and doesn't do squat, forever. The only thing I notice is the q mount command shows something odd: tsm:>q mount ANR8376I Mount point reserved in device class LTOCLASS1, status: RESERVED. ANR8334I 1 matches found. I've never set anything in the server to be 'reserved'. This is happening completely unexpectedly. I have no idea on what to do, as the actlog shows zipo on this error. I don't even think TSM thinks it's an error. I will work on it in the monring, but maybe someone has a quick fix. Didn't find one in the list... Any ideas? Alex
