It works. I'm currently using both an IBM 34560 LVD (4.5GB) and an
IBM 39130 LVD (9GB) in SE mode (I ordered "wide SCSI drives" and my
vendor shipped me LVD ones ;-). They're very nice, and are attached to
a Gigabyte 6BXDS (Adaptec 7895) motherboard. I also have another plain
F/W (not LVD) IBM 39130 on the same SE bus, and I'm using vinum to
stripe the LVD and plain F/W 93130 drives. They work well.
The only thing to note about LVD drives is that they have *NO*
provision for on-drive termination. All termination must be provided
elsewhere.
