DAT 72 problems

[alexey sipkin]

hi,
i have hp server rp3440 with hp-ux b.11.11. when i try to connect hp dat 72 external tape drive (scsi) system couldn't find this device. rebooting the server didn't solve the problem. how can i identify the problem? (unfortunately i don't have spare LVD terminator and VHD-to-HD scsi cable to check their integrity).

When you run ioscan, do you find any "unknown" devices? Is the stape driver loaded in your kernel?

when i try to add tape device via sam the system answer: all related tape-drivers are currently configured into the kernel. No kernel rebuilding is necessery.
result of ioscan is attached.

Shalom,

These new tape drives are supposed to be self terminating.
Sometimes what looks like a scsi connector is not. The new (for hpux) smart card adapters intended for raid hardware mirroring will not support a tape drive like this.

If there is an alternate scsi connection, try it. Also try a fresh cable.

in installation guide lvd terminator is mandatory fo this device.
unfortunately i have only one scsi interface on server and one cable.
any other ideas?
