Tachyon XL2 and Overland NEO2000

Hi,
We have connected Overland NEO2000 (tape library) to L1000 running HP-UX 11.23. We have connected NEO2000 via HP Tachyon XL2 Fibre Channel Mass Storage Adapter. Initially the tape drives were not showing up on "ioscan -fn". After searching ITRC, i got the solution here (http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000080092716)

When i changed "Hard Address Assignment" on Overland NEO2000 FCO (Fibre channel Option) to enabled, "ioscan -fn" started listing tapes drives.

But i am still seeing UNCLAIMED UNKNOWN in "ioscan -fn"

unknown -1 0/3/0/0.8.0.255.0.3.0 UNCLAIMED UNKNOWN OVERLANDNEO Series

Here is the complete list of "ioscan -fn" output for Hardware address 0/3/0/0

ctl 4 0/3/0/0.8.0.255.0.3.3 sctl CLAIMED DEVICE Over NEO VIA FCO
/dev/rscsi/c4t3d3

Has anybody had the same issue? OR Can anybody give hints as to why am i getting UNKNOWN H/W.

Thanks

You need to add the "schgr" kernel driver.

Once this is done, reboot and the device will be CLAIMED.

Torsten,
thank you very much for the answer. It worked. I enabled the schgr module in the kernel and rebooted. "ioscan -fn" now shows like this

autoch 0 0/3/0/0.8.0.255.0.3.0 schgr CLAIMED DEVICE OVERLANDNEO Series
/dev/rac/c4t3d0

Thanks
