If you are loading the driver with modprobe post boot, or you are using
an initial ramdisk, you need to either specify the verbose option
on the command line to modprobe or specify the setting in /etc/modules.conf.
For my initrd setups, I have something like this in /etc/modules.conf:
alias scsi_hostadapter aic7xxx
options aic7xxx aic7xxx='"verbose.tag_info:{{8.8.8.8.8.8.8.8}}"'
If you just want the verbose setting, replace the above option line with:
options aic7xxx aic7xxx='"verbose"'

This is because you don't have any bootable devices on the chain.

This is an internal changer?
Does the changer have a dip switch to enable termination? If so, this
should be *off* for your configuration. An over-terminated bus can be
just as deadly as an under-terminated one.
