Description: IBM LTO drive
Revision: 8711 Device type: lto [13] Flags: 0x0005

[Cause]
To use atdd device , mksf command is executed to create Passthrough device file but it failed .
[Workaround]
IBM suggests using native operating system device driver (stape on HP-UX) for IBM tape drive .
So, mksf command doesn't expect atdd .
.omnirc variable OB2SAFEINQUIRY=0 can be set on the HP-UX server where the tape device is connected .
It makes DataProtector skip the step of mksf and directly access the related device file. (ex. /dev/rtape/tape169_BESTn)
