Environment: Networker 6.1.1, Shared Library, 18 DLT7000 drives -DDS via 
SmartMedia. Server Parallelism is  42. On a particular Server that is a storage 
node, I have 18 x 70GB superfast mount points that need to be backed up in the 
shortest amount of time possible. Of course the fastest way to do this is to 
stream one mount point (saveset) to a drive so all 18 drives are engaged all at 
once - and I tried using target sessions  set to 1. However, this scheme only 
work sometimes... like if Networker is taking a long time to figure out what 
tape(s) to load it would still insist in multiplexing save streams to the 
drives... Any other  "recipe"  or solution to this problem?

Similarly, we have a requirement that such backup set (18 x 70 Gb filesystems) 
needs to be restored on  different servers that also act as storage nodes in 
our Tape Area Network. We could not employ diskgroup floaters or SAN based 
techniques to achieve this so we're left to using our TAN via the tape drives 
to do this task. 1st to be hurdled was how to do the recovers so that it will 
use the drives native to the server and not use the original backup set's 
storage node - which we did using an on-the fly change of the storage node 
parameter prior to the recovers. To recover the backup set, we just background 
all 18 recover sessions and expect things to go on.. sometimes this works 
sometimes it does not specially when a volume contains 2 or more savesets that 
are concurrently being recovered.  My Q. - are there any undocumented settings 
that say if a volume had multiplexed savesets that it can also "multiplex" the 
recover?

Thanks.

NELSON
