My thanks to Alan from Digital Support (Atlanta):
According to Alan, the problem is related to the SCSI bus
holding the devices which is preventing LSM on systemB (DU40b)
from accessing them.
His solution:
from systemA (du32c) - voldg deport test_dg
voldisk rm rz18
scu -f /dev/rrz18c release device
from systemB (du40b) - voldisk define rz18
voldg import test_dg
volume start test_vol
volprint -Aht (to check)
You may need to make the soft link if using Advfs
in /etc/fdmns.
It worked!
Thanks again Alan.

Original question:
--------------------------------------
Hello,
I am in the process of upgrading our DU3.2c systems (systemA, systemB)
to DU4.0b, under LSM, and in a DecSafe environment.
I have broken apart the DecSafe members and have installed
DU40b (upgrade install) and Trucluster Avail Server on 'systemB'.
I then stopped a Disk Service (test_service) on DU32c (systemA),
deported the disk group (test_dg) and varied offline the disk
associated with the disk group (rz18).
Then on systemB (DU40b), I did: voldiskadd rz18
voldisk online rz18
voldg import test_dg
voldisk -Aht
Everything works except that I don't see the vol info
for the disk group.
How can I add the vol information for this disk group?
Once I can get the disk group online manually I will add it
into TruCluster Avail Server later.
Thanks,
