NetWorker 7.1, Solaris 8   (this is a server, or more properly, storage
node issue)

Scenario:  backups underway, and server is waiting for some quantity of
recyclable tapes (let's say 8.)   Upon loading recyclable tapes, nsrd
makes some nsrjb requests to re-label 8 tapes.  As soon as the first one
is labelled, however, it appears that not only is it loaded into a drive
for writing, but that a majority, if not all, of the suspended sessions
get routed to this one tape (i.e., target sessions for whatever drive
appears to be ignored.)   The result is that we may see as many as 25-30
streams going to one tape, while the remaining 7 newly-relabelled tapes
sit idle in their drives.

Anybody else seen this behavior?

Yes, under several circumstances. A flaw in the code somewhere. It is
very annoying because sometimes this can cause a backup to run for many
times as long as it should, sometimes into the next backup window. It
doesn't even sort it out when the tape fills, it still continues with a
zillion sessions on the next new tape. Fix it Legato!
