Try this patch, chg-robot retry the mtx command if it failed with 'No
Sense'.

'it always works the 2nd time', Did it always works the 3rd and 4th
time?
Yes, after the first fail, it always works. Then several days
later I try switching tapes and it fails again the first time and
always works again after that.
When is the first time?
The "first time" is Monday morning after I've done a dump to the
holding disk. I do 6 amdumps during the week:
M degraded
T flush to tape
W degraded
Th degraded
F flush to tape
S degraded
