I now have it working; here are the changes:
- New replacement PX502 from Quantum.
- Directly connected (via FC) to Retro CPU.
(And therefore using only a single drive, since this CPU has only 2 FC interfaces. :()
Points to Quantum for (FINALLY) sending the full, new replacement unit instead of continuing to "nickel & dime" parts.
Points to EMC Insignia for suggesting a direct connect.
Serious points taken away from EMC Insignia for not working via a FC switch! :(
More points taken away from EMC Insignia for not adequately testing the PX502 - contrary to explicit support ("Qualified - Passed extensive in-house certification. Storage device is fully supported.") on their website.
More points taken away from EMC Insignia for saying they finally got a PX502 to test (!) and stringing me along on the results - still haven't heard and they last told me they'd give me an update a few weeks ago. :(
More points taken away from EMC Insignia for trumpetting that they'll be at MacWorld - talking about the moribund V6.1. I just hope and pray that's a smokescreen for the REALLY LONG overdue next version. We'll see soon enough...
