We have an Alphastation 200 that is being used by our users to
transfer data from old tapes to new ones. To facilitate this, we have
4 SCSI tape drives attached (4mm, 8mm, 3480, and 9 track), as well as
the internal HD and CD-ROM. We needed to add swap space, and tried to
add an external hard drive to serve as swap and a larger /tmp.
Anyway, in addition to some system wierdness with the 8mm drive
before the new drive was installed (tapes wouldn't be able to be
recovered from), now the system won't boot. It boots fine with just
the new HD, and with just the new HD and one other device. If we add
any more than that, somewhere the startup (not always in the same
place), we get bombarded with scsi cam errors.
I am wondering if splitting the devices between two SCSI busses would
help? This would involve buying another PCI scsi card, in which case
I have another question: Can I stick a "regular" PCI SCSI adapter in
there? Or are the PCI slots somehow non-standard?
