AIT-100 Drive /Arcserve7 no function

[Ayman Altounji]

Hi from Germany

I installed a CPQ AIT 100 Tape drive internal in a ML370G2.
There are 2 Drive arrays configured on the integrated 5I controller (3x18+3+36Gigs),memory is 1,5 GB, Operating System NW 4.11 patched to 4.2 (NWSP7a).
All looks fine, but while Arcserve 7.0 is starting the AIT drives never stops to initialize the tape drive (Access light is flashing).
i tried to use a CPQ 12/24 DAT connected to the same Port -> all works fine.
CA certified device list -> the AIT 100 is listed.
Termination is OK. I have no more idea.
(COMPAQ Support Centers answer -> there is no support for nw 4.11 on this machine)
Any answers or ideas may be helpful
