hi. we have a DD630 running in vtl mode running like a champ (despite
the licensing / changer silly-ness with NW/EMC).
I find your issue of having to relabel daily a bit odd - cant you create
enough vtl tapes in the lib to cover your retention policy/(s)? if you
are on vtl, you are not using AFTD, correct? (or perhaps both?)
what do you mean sessions are set to 1 per dd? do you mean 1 per drive
on paralellism on every DD unit ?? - that would be correct, so you have
to create more drives than normal to over-compensate for the lame
parallellism setting.
We just followed the best practice guides for nw and dd we found on
powerlink or on datadomain.com - they have done fairly well for us
despite some early issues/problems with licensing and stuff... sorry i
dont have specific config details, but can have them by the am, email me
off-list if you'd like more info.
cheers,
james

Subject: [Networker] False "Tape is either disabled or in service mode"
message
Running NW 7.5.2 with Data Domain DD880 in VTL mode. When a backup with
several clients kicks off, NW may want to mount 12 or more tapes (tape
sessions are set to 1 per data domain). We get several of the red arrows
with a message like this: "Device `rd=nt2legatok4.emn.com:\\.\Tape0' is
either disabled or in service mode." These are not true as the tape
drive is not disabled or in service mode, and if you look further you'll
see that the volume it is trying to load is already mounted on another
drive and may even be writing at the time. I suspect it has something to
do with sessions being set to 1, but I've logged an SR with EMC and they
have not yet suggested that. Updating the tape drivers (this is windows
2003 for the server and win2008 for the storage nodes) has not helped.
Is anyone else running NW with DD880 VTL, and is anyone else seeing
these kinds of messages.?
Thanks
Robert D Mumford
