Re: [Networker] {Networker] Windows2003 R2 change tape order at boot

Hello all,
just to be sure...
can we use the IBM tape drive persistent logical tape drive name binding on
windows for use for Networker? or can this only be used for TSM on windows
does anyone actually tested the following (or any other config, which gives
absolute prove)
startsituation
windows server with acces to 3 tape drives
tape0 --> \\.\Tape0
tape1 --> \\.\Tape1
tape2 --> \\.\Tape2
for some reason the physical tape1 is not accesible and the windows server is
rebooted. normally this would result in the following tape mapping
tape0 --> \\.\Tape0
tape1 -->
tape2 --> \\.\Tape1 (which will cause problems!!!)
following what I read, using the new driver this should give
tape0 --> \\.\Tape0
tape1 -->
tape2 --> \\.\Tape2
is this correct?
besides this, the same question for the tape drive and robotic failover
feature. does anybody has allready tested this with networker
thanks
bart

Thank you very much to Gaddy and Terry for providing this information regarding
persistent binding, which was new to me.
Windows has for many years been deficient in this respect, and it is
disappointing that it has taken so long for a solution to arrive.
However now that one exists, the lives of the poor souls who have to look after
NetWorker on Windows will be a little improved.
Windows / NetWorker admins should take note of this thread, since this
information is very significant. I have saved the details for future reference.
Other OSes have had this issue sewn up for years.
* Solaris can do solid persistent binding to a SCSI address, then the mapping
from there to device names is easily controllable and only happens when you say
it happens.
* AIX does the best job by directly mapping a WWNN to a device.
* Linux I *think* can do this stuff properly using udev, although I am not
totally conversant with this.
* HP-UX mostly gets it right but has other issues in this area.
