Raj,

You can try to do a "tape open devname" from nfxsh to see if a tape is
really in there (if you suspect the DMA). From the message though -
looks like the tape has been unloaded.

Update:

Backup works. Restore fails. In our ndmp trace I see the following. This
is also a possible DMA issue (very low probability). Lets see if vikas's
restore go through.

Tim and I have tested the new code drop reasonably well but we need
someone to run a real dump and restore test, preferably one that has
been failing to date.  Vikas, can you or someone you designate do this?

The code in this branch seems to have the I/O stall fixed.  I ran the
*_stress tests that were in the defect until I ran out of disk space so
I think we are good on that.  It would be nice if someone with more disk
space could try this out.  Sandrine, can you do this one for me?

I have made builds for all targets in
~jong/src/fb-jong-perf2/Build


Please copy files rather than booting off my directory via NFS, since I
want to be able to change things without impacting you.

Tim and I still run into the Cougar SCSI ASSERT on timers already being
stopped so that bug is still with us.

My branch has dev changelists up through 28399.  I will get it current
later today.
