I think that your emulation does't work well, Netapp use this data as tape configuration

file for IBM Ultrium-2 (IBM_LTO2_ULTRIUM.TCF):

CDB 0x15 is SCSI-Mode Select Command, h_density=0x42 and h_algorithm are correct values

for the original IBM tape, apparently not for your drive - you got an Illegal Request Error.

Try to find out what your drive expect there - it should be described in the "scsci programmers

guide" for your drive.

Good luck,

Betreff: LTO-2 drives issues

Hi All,

I installed a Library StorageTek L80 with one drive LTO2 Certance Ultrium 2 connected via SCSI LVD to Filer F840 with Ontap 6.4.3. This release does not support LTO 2 so I dynamically qualified a IBM Ultrium-TD2. Then I emulated Certance Ultrium 2 as IBM Ultrium-TD2 with success.

But a error appears when I try to use LTO2 format (rst4a/h), wich is displayed but not recognized.

Does someone suffer a similar issue?

Thanks
