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
