Yes, both checkout and move drmedia move one tape at a time and wait for it to complete before moving on to the next. TSM does not queue up the ejects on the 3494 the way MVS does.
If you're doing a lot more than 30 ejects at one time, you might want to consider defining a bulk I/O wall in your 3494. David Ehresman >>> [EMAIL PROTECTED] 8/23/2004 3:22:07 PM >>> We are preparing to migrate our TSM server from z/OS to mainframe Linux. Both old and new servers will use a 3494 tape library. The z/OS server relies on z/OS to handle tape library management. As a result, it does not have a 'checkout libvol' command, or a 'remove' option for 'move drmedia'. The documentation for the 'checkout libvol' command indicates that the command will not complete until a slot in the convenience I/O station is available. This would be a significant nuisance for us. The TSM server will problably eject about 30 volumes per day, and the surviving z/OS applications will eject even larger numbers of volumes from the same 3494. Will the 'checkout libvol' command really wait for an empty I/O slot? Will a 'move drmedia' command with 'remove=yes' also wait for an empty I/O slot?
