Hello Michael,

Assuming that lib1 and 2's devices are not connected to same hosts
(in other words, a storage node not using devices from both lib 1 and 2),
you could achieve such a setting when playing with clone storage node
affinity and allow Sdlt320 and Sdlt600 in your pool "CLONE".
In case of mixed device type per storage node, restrict devices from pool
to not allow that/these device(s) or to restrict to 1 single type.

If you did not list in Clone Storage Node (CSN) affinity the SN that 
has/have
connection to Sdlt600 devs, Legato will never write to these devices
but you can always recover from by mounting tapes manually.

To be mounted and usable for reading, do neither forget media type of the 
volume
(that is set at volume label time by labelling device) must be the same than

your
device setting in legato (device type). So, if the Tape device is defined as

SDLT600
and medium labelled on a SDLT320 device, networker will refuse to
mount the volume, claiming on different media type (although hardware may 
support it!)

For the rest, no other way, I think ....

HTH

Objet : [Networker] Can I make a pool RO on one set of devices, and RW on
another?

Say I have a pool CLONE. Ideally, I'd like to make this pool RW on library 
#1, but RO on library #2 (because library #1 is SLDT-320, and library #2 
is SDLT-600, and I wouldn't want the tape to be written on, if it was in 
library #2). Any way to do this in NetWorker?
