Sorry, the first message did not have some info and one line was not pasted
correctly

I am having problems where we have down drives, and other strange behaviour
(a job mounts a tape in a NDMP storage unit instead of its own)

We appear to have the right configuration, and when things go to the right
drives (and the drives stay up), we can get 264gb done in 2.5 hrs using 4
sdlt220 tape drives.

We have a case open with Veritas, but I am hoping someone else may have gone
through this.
I have used robtest to move tapes into each of the drives and then used mt
commands to get the status of the drive and this has worked (did not try to
write)

Here is some of the testing I have done so far, to see if there is some
mismatch between what veritas things of the drive name/path and what the OS
things the drives are.
The drives are scsi ids 1-7 (7 being directly attached to the NetApp filer
using ndmp)
The robot is scsi id 5
I also did another ioscan to verify that the "I" value was on the c720
ext_bus

Thanks

Steve Darragh

------------------------------------
I added the ext_bus for each of the drives
