[Networker] 6.1.3 "service mode" for a tapedrive ?

> In the past we'll occasionally see a drive automatically disabled but now
> more drives are automatically going to "service mode".
> Will it always do this where it used to automatically set it to "disabled".

> A. For NetWorker versions prior to 6.1.3, NetWorker takes immediate
> action when you disable
> a tape device. This can have negative results if the device is in
> active use performing a backup
> or recovery. To avoid this situation, users need to make their request
> when the device is idle.
> With version 6.1.3, NetWorker queues the > "> request to service> ">
> the drive and automatically
> disables the device the instant the drive becomes available. Thus if a
> tape drive is actively
> performing a backup or recovery, NetWorker will not disable it until
> the save/recover operation
> is complete. Very nice!

> and from the Release Supplement for 6.1.3:
> Service Mode Added to Enabled Device Resource (LGTpa48832)
> The Enabled attribute in the Device Resource window has a new Service
> mode. Prior
> to release 6.1.3, the Enabled attribute had two modes: Yes and No.
> Service mode is different than the Disabled attribute because the
> nsrmmd process is
> not stopped. No more sessions will be assigned to the device once it is
> placed in Service
> mode. If the device was active when switched into Service mode, the
> current sessions
> will complete and the volume (if in a jukebox) will be unloaded.
> This mode takes the drive out of the pool for drives that the NetWorker
> software is able
> to automatically select. The drive is available for manual operations
> specifically
> selected using the -f option (the NetWorker Administrator program
> already does this).
> Note: Load/mount operations cannot be performed on devices in Service
> mode.
