Beware, beware ...

1) In all cases, check Channel Adapter firmware revision, or have it
checked by HP. There is a minimum firware version for the CA to support
SCSI cards. AFAIK, all 980s should be OK, but ...

2) If these disks are bootable (i.e. include LDEV 1), make sure PDC
(Processor Dependent Code) revision is at least 3.56, or, once again, have
it checked by HP.

3) In all cases, your 980 is limited to SE (single-ended) SCSI. No
Fast-Wide on (you correctly stated) these old dinaosaurs.

4) And, as far as performance is concerned, remember that the 980 is, in
terms of CPU and main bus speed, more like a DC-6 than an F-22.

Otherwise, it should be OK.
