Please advise if this tape drive can not be used with Netbackup Datacenter.
which is the cheapest model from Sun that can be used.
how about DLT drives ?
Please advise.

OK, so in short are you saying I can use 0hbn in veritas
drive configuration ? I tried 0hbn .. here are the same results.
Please advise which device I can use in Veritas.. none seem to work.
# mt -f /dev/rmt/0n status
Exabyte EXB-8500 8mm Helical Scan tape drive:
sense key(0x0)= No Additional Sense residual= 0 retries= 0
file no= 0 block no= 0
# mt -f /dev/rmt/0hbn status
/dev/rmt/0hbn: no tape loaded or drive offline

Right there is the hbn device.
cbn is normally for compression (and would be on an 8500c), so the the
8500 is complaining about it. 'hbn' should be the same density setting,
but without compression.
The Solaris 'st' device has 4 different density settings available to
it. In order they are 'l', 'm', 'h', and 'c' or 'u' ('c' and 'u' are
identical).
For most exabyte devices, 'h' is the highest density setting supported
by the device, with the 'c/u' device the same density but with
compression. The 'l' device is usually one density level behind
(probably compatible with the EXB-8200) and the 'm' device would be the
same but with compression enabled.
Besides that setting, the 'b' may or may not be present and defines
some characteristics of how the drive behaves to the driver, and the 'n'
is whether or not the tape will rewind when it is closed.
