Hi,



We are seeing a case where NetWorker is failing to mount a tape on a new
dedicated storage node due to it believing there is a serial number
mismatch.



The first time we saw this, I had configured the drives manually (via
jbedit), so there was no serial number in the tape drive resource.

The second time, I used dvdetect and the gui based autochanger
configuration method.



The server's daemon.log shows the following:

…

38752 02/06/13 11:07:29  nsrd rd=crm:/dev/rmt/2cbn Eject operation in
progress

42506 02/06/13 11:07:29  nsrd media alert: device "/dev/rmt/2cbn": serial
number                          mismatch, check system device ordering.
Expected "Serial Numbers:ATNN=IBM     U
LTRIUM-TD2     351A600203:351A600203", found ":ATNN=IBM     ULTRIUM-TD3
7410                         810032:7410810032"

72504 02/06/13 11:07:29  nsrd rd=crm:/dev/rmt/2cbn eject operation failed:
read                          open error: drive status is 65329 35 The
drive serial number has changed

error:                          drive status is 65329 35 The drive serial
number has changed

…



I'm noticing the following:

1.       the serial number mismatch says "/dev/rmt/2cbn," not
"rd=crm:/dev/rmt/2cbn"

2.       The serial number of rd=crm:/dev/rmt/2cbn is 7410810032. This is
in changer "DD1"

3.       The serial number of /dev/rmt/2cbn (on the backup server) is
351A600203. This is in changer "CDL-old"



Environment Info:

NSR Server is Solaris, NetWorker 7.6.4.5

NSR Dedicated Storage Node is Solaris, NetWorker 7.6.4.5



Anyone see this, or have any thoughts about it?
