I'm running FreeBSD 2.2.7-RELEASE from a 2g scsi.
I received the 3.0-RELEASE cd in the mail this week and want to install
that. I also recently purchased a 9G scsi to add to the system.
I'm awash in options here, but maybe the easiest is to take out the
2G, put the 9G in and do a virgin install. Then worry about getting
the 2G back in. My main concern is the lack of termination on the
drives. The drives are both Quantum with an SCA interface. Does anyone
have any experience with this type drive? The current 2G (Viking) works
fine. The controller is Adaptec 2940 U/AHA-2940UW . The boot used to
warn abount auto-termination until I diddled with something in the scsi
bios. My scsi cd uses a 50 pin cable on the other connection and is on
the other end of the chain. The new drive would have to go on the same
cable with the old drive and the one closest to the 2940 would need to
be set un-terminated.
Is this just sort of a no-brainer that I don't need to worry about?
Is the 2940 that damn smart?
Both drives, by the way, come with a 68-80 pin adaptor.
The big drive number is QM-39100AL-SCA.
Since it came from Frye's, it has no manual.
The following is part of a web page at Quantum which (I believe) refers
to my drive:
"The Atlas III SCA drive does not provide for physical
configuration of the SCSI ID. Quantum disk drives that utilize the
80-pin SCA connector do not require any jumper configuration for SCSI
ID. Systems that use SCA connections, typically, auto-configure the SCA
device. This configuration is determined by the system at start-up or by
user definition during system setup. Contact your system manufacturer
for details on setting SCSI ID. "
I know this is a hardware question. If you know of a better forum for
it, please tell me a place to go (besides Hell).
I do have other FreeBSD questions, which I'll put under separate posts.
