Hi,
This week we enabled
the WWN-feature on our L700 tape-robot. This means that all the devices
(tape-drives, robotic arm) got a new WWN-number. The devices own WWN-number is
not longer advertised now the robot itself advertises a WWN-number for the
device. The benefit of this is that in case of a hardware-replacement nothing
has to be changed. Not on the SAN and not on the OS and not in Netbackup.
This week, after we
enabled the feature, we changed the SAN, then we started to connect the
tape-drives at OS-level.
We have several
Solaris 9 mediaservers. On all servers we could connect the drives without a
reboot with hthese commands
-
cfgadm -al (to show
what is connected)
-
cfgadm -c configure
cX (to configure controller X)
-
devfsadm -C -c tape
(to get device files for the tape-drives with the new WWN)
After that we could
configure them in Netbackup
This went fine for
all the mediaserver without a reboot. Except one and this server is our main
production system and cannot easily be rebooted.
We tried a lot of
commands we found with google. But the output of cfgadm –al keeps showing the
old WWN-numbers of the tape-drives.
Has anyone seen this
behavior before? Or does anyone has a clue on how to solve this without a
reboot?
Regards,
Rob
