Hi Folks,
I have been getting a lot of backup jobs failed with error code 52 i.e
bptm timout.
Upon going thru logs/bptm/log.<mmddyy> , i noticed the part where bptm
gave up was
15:59:47.618 [21913] <2> write_backup: media id W425L2 mounted on drive index 2,

Apparently, bptm mounted, the media i.e W425L2, successfully, but when it tries to position the head
to block 4321207, it failed. As if that block is not there !!
W425L2 is a NEW media which I have unwrapped 2 weeks ago.
This also happened to a mixture of 7 other medias ( mixture of old and new ) over 3 weeks.
So i doubt its a media issue.
Having said that I dont think its drive problem as well.
Becos the I have another 2 drives, which gave the same error when using the
said medias.

Any clue on what is happening here ?
BTW my L100 tape library was found to be hung on 7 Dec 2009. All jobs
failed with code 52, causing by bptm timeout from unable to mount media.
( reasonable, because the robot has hung as well ).
Assuming that the lib was hung as early as 5th Dec, could it have anything to
do the scsi locate error ?
Any insight or suggestion would be most appreciated.
Thanks in advance.
