I'm running 6.5 sp1 and arcserve 9.01.
xiotech san box with a Brocade fiber switch.

Lately I have been getting the following error an the console prompt:
CheyFC: Unknown HACB error [00010008]. This happens when the tape
library does an inventory of the tapes.

In working with CA we have done the following:

Replaced the Spectra-Logic 2K tape changer.
Replaced the Transducer- Fiber to 9 pin d connector.

CA says the error is a hardware problem.

Anybody have an Idea?
