Shadow Volume on NCS - Backup with Syncsort BEX

Question

Hi all,
I've got a Shadow Volume working great inside NCS, but my problem is I'm not able to backup the Shadow volume part.
In BEX I'm able to browse and expand both the Primary volume and the Shadow volume and see the correct files (as my Shadow rule stores only ISO files) Backuping up files in the Primay volume works great, but when selecting the Shadow volume the job fails.
I'll chated with Syncsort's support team and told this should work with there software. Has anyone done this? is there something I need to do to the way my Shadow Volume is setup?

I ran across this thread while trying to find a solution, so I am posting here in case anyone else has this problem and needs a work around for backing up a cluster DST shadow volume.
We ran into this issue and spent a lot of time with Syncsort support. We found our own work around.
The problem according to Syncsort is that the archive pool/volume do not show up when you run the command #slptool findsrvs smdr.novell.
In Novell's documentation the cluster pool associated with a DST Shadow Volume is not to be brought online. The DST Shadow Volume is brought online as part of the cluster pool of the volume it is backing. So what we did is modify the cluster pool script for the DST Shadow Volume pool so that it doesn't actually bring a volume online but the pool can still be online. So now both cluster pools are online and are showing up in slptool but the volume is still mounting as part of the other pool. Since the pool is now showing up in slptool we can back up that volume.
Below are the cluster pool scripts. The first is the script of the cluster pool which brings up both the main volume and the shadow volume. The second script is for the cluster pool associated with the shadow volume but which has the lines commented out which mount the volume (we don't want the volume to mount twice).
#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs
# activate the secondary pool
exit_on_error nss /poolact=U1ARCPOOL
# activate the primary pool
exit_on_error nss /poolact=USERS1POOL
sleep 5
#exit_on_error ncpcon mount USERS1=252
exit_on_error ncpcon mount USERS1=252,shadowvolume=U1ARC
exit_on_error add_secondary_ipaddress 10.10.10.127
exit_on_error ncpcon bind --ncpservername=SC1-USERS1-SERVER --ipaddress=10.10.10.127
exit_on_error novcifs --add '--vserver=".cn=SC1-USERS1-SERVER.ou=NCS.o=SURGERY.t=SURGERY."' --ip-addr=10.10.10.127
exit 0
#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs
#exit_on_error nss /poolact=U1ARCPOOL
#exit_on_error ncpcon mount U1ARC=251
exit_on_error add_secondary_ipaddress 10.10.10.128
exit_on_error ncpcon bind --ncpservername=SC1-U1ARC-SERVER --ipaddress=10.10.10.128
exit 0
