HP6400 DDS autoloader

I can't seem to get Omniback to recognize the fact that my device is an autoloader. It used to work under HP-UX v9x, but it doesn't under 11.00. Omniback version is 3.5 (I also tried 3.0). An ioscan gives me:
tape 2 56/52.3.0 tape2 CLAIMED DEVICE HP C1533A
/dev/diag/rmt/c2t3d0 /dev/rmt/2mn /dev/rmt/c2t3d0BESTb
/dev/rmt/2m /dev/rmt/2mnb /dev/rmt/c2t3d0BESTn
/dev/rmt/2mb /dev/rmt/c2t3d0BEST /dev/rmt/c2t3d0BESTnb
unknown -1 56/52.3.1 UNCLAIMED UNKNOWN HP C1553A

It seems to see the DDS drive, but doesn't recognize the autoloader portion. Trying to add it in Omniback as anything other than a standalone just tells me that there are no driver files available for it.

Any suggestions would be greatly appreciated. I lost data last week because I couldn't get the backups running on my autoloader.

Hi there.
Did you install the driver for the change mechanism as well ?
( Just a funny idea ).

Re: HP6400 DDS autoloader

Just to verify (given the following info):

ext_bus 2 56/52 scsi1 CLAIMED INTERFACE HP 28655A - SE SCSI ID=7
target 23 56/52.3 target CLAIMED DEVICE
tape 2 56/52.3.0 tape2 CLAIMED DEVICE HP C1533A
spt 0 56/52.3.1 spt CLAIMED DEVICE HP C1553A

# lsdev -d spt
Character Block Driver Class
172 -1 spt spt

The mknod command for the driver would be:
# mknod /dev/2pick c (172) (0x023000)

Should this be /dev or /dev/rmt? Are the parentheses required?

Hi,

parentheses are NOT required:

mknod /dev/2pick c 172 0x023000

It's not nessesary to put it into /dev/rmt, you canput it into /dev

Re: HP6400 DDS autoloader

I got a "no such device or address" when doing the scsi_io command. I then tried recreating the /dev/2pick device file using 0x023100 instead of 0x023000 and got:
This thing claims to be: HP C1553A NS00 58

Does this sound correct? I then tried to add it as a Stacker in Omniback using the /dev/2pick driver and it still doesn't work.

Re: HP6400 DDS autoloader

I deleted the stacker in omniback and added the drive as a SCSI-II Library using the /dev/rmt/2pick driver and it seems to be working. It's at least scanning the tapes now. Thanks for your assistance.
