Any messages in the syslog from the 3.4.1 master or from the filer? What patch
level are you at with the 3.4.1 master? - I seem to recall an NDMP patch in
there somewhere... I'm also wondering about any Solaris 2.6 patches that might
have an impact. Don't know anything about that particular version of Data
onTap. We went from 6.4.2 to 6.4.3 with no problems.

I'm looking for help on restoring some files from one of our NetApp filers.
I used to be able to restore fine but now it's having problems. The
OS on the F740 was upgraded to Data OnTap 6.4.2P6 which may or may not be
significant.
The image itself is ~450GB in size spanning 6 AIT-2 tapes, and is composed of
millions
of files. The particular subdirectory I'm interested in is in a directory with
30 000
other subdirectories.
When I go to restore (NBU 3.4.1 on a Sol 2.6 master), it mounts the first tape,
sits
there for 5 mins and then I get a time-out error and the restore fails.
I tried to do a manual restore: manually loading the tape into a drive attached
to the
SUN, positioning the tape (mt -f /dev/rmt/0cbn fsf 3 ; mt -f /dev/rmt/0cbn fsr
2) and
using ufsrestore to recover the files. That works fine for the first tape, but
I can't
seem to get the positioning right for the subsequent 5 tapes. They are all on
the first
fragment so I would have expected (mt -f /dev/rmt/0cbn fsf 1 ; mt -f
/dev/rmt/0cbn fsr 2)
to work, but it complains that the image isn't in dump format.
We also have a NBU 4.5FP7 master server, so I pulled the tapes out, imported
them fine
on that machine. Started the restore and it's running along at the painful
rate of
50-100K/s (this is on an AIT-3 drive).
Any thoughts/help would be appreciate, thanks.
