[Networker] Problem with NDMP devices
2007-10-19 12:44:58
As you may recall, I wrote to this list seeking assistance with
reviving my failed NetWorker 7.4 Solaris 9 server. I initially had a
situation where after doing an mmrecov, the local tape library and
all its devices were duplicated in the devices and storage nodes
resource lists. Thanks to Conrad Macinina, I learned how to delete
the resources, which allowed me to use jbconfig to recreate them
properly. That's fixed and I ran lots of successful backups last
night, except for NDMP clients.
My tape library is connected to my backup server via fiber channel.
We have five of 14 tape drives in it allocated to NDMP backups, which
we do over our network. The NDMP clients are not connected to the
tape library. When I created the tape library again using jbconfig, I
specified devices in the format rd=hostname/dev/rmt/xcbn (this is
Solaris 9). I see in the documentation it says to specify "(NDMP)"
but I didn't do that. The jbconfig utility came up and asked me if
the device was NDMP and I replied in the affirmative. I provided the
same userid and password that I previously used.
When I look at each NDMP tape resource, it says its NDMP and it looks
fine as far as the configuration goes. Unfortunately, any time I try
to load or label a tape in either of those 5 drives, I get an
"unknown error" and also after a few minutes, and error about a
communications problem.
I don't think that not providing the "(NDMP)" string would make a
difference, especially since I didn't have that prior to this server
failure, so I am wondering if that is indeed the cause of this
problem or if its something else. If any of you who are running
NetWorker 7.4 with NDMP backups has any ideas to share, please let me
know. I have a case open with EMC about this, but I am still waiting
for assistance. At first, I thought it was because I mistyped the
userid in the storage node resource, but correcting it didn't fix the
problem.
