Hi,

I enabled a previously disabled device last night. This is a Seagate LTO
gen. 1 drive. There are 4 drives (/dev/nst0-4) in this Storagetek L80.
Anyway, I come in this morning to discover that NetWorker apparently
thinks /dev/nst0 is a read-only device. There were a lot of messages in
the log file indicating that /dev/nst0 is a read-only file system, so it
was unable to write to any tapes using that device. I checked the device
configuration under nwadmin, and it was 'Enabled' and 'Read only' was
set to 'no'. Not sure about 'Write enabled' since that's listed under
details so may not have set that last night before going home. Anyway, I
set it to 'Yes' this morning, but as soon as I tried to label a tape in
that drive, same error:

Wed 10:34:26 AM rd=snode:/dev/nst0 Label without mount operation in
progress
Wed 10:34:28 AM media warning: rd=snode:/dev/nst0 opening: Read-only
file system
Wed 10:35:28 AM rd=snode:/dev/nst0 write open error, Read-only file
system
Wed 10:35:29 AM rd=snode:/dev/nst0 Eject operation in progress

How or why does NetWorker think this is a read-only file system?

We're running 6.1.1 on Solaris 2.8 server with Linux storage node
(snode). Storagetek library is attached to the storage node.

Any help would be appreciated.

Thanks.

George
