HP – Smart Array P600: Can’t Get Drives Recognized on Port 2i

Extensive searching proved fruitless (and aggravating), so I'm moving from lurker to poster, finally! :)…

I have an HP ProLiant ML-350 G4p that I just converted from SCSI to an SAS/SATA machine (swapped out drive cage and switched RAID controller to a Smart Array P600). I initially bought 4x 1.5TB SATA drives (cheap Hitachi drives from retail, BTW), and I set those up on Port 1i with Great Success. The configuration is RAID 5 and has worked great for a month+.

I got the itch to both max out the drive cage ("why have empty bays??", I thought), extending the array with one drive and making the 6th drive a live spare to help ease my sudden paranoia pangs about having this much data in one place. (I debated switching to RAID 6, but chose RAID 5 + hot spare, instead. As a side note, if anyone disagrees with this, please advise?)

At this point, I found out that I can't get drives to recognize on port 2i! The drive doesn't show up in the BIOS array editor, and the light indicator in the drive tray is a solid amber light. This amber-lit situation is the same no matter which drive(s) I have plugged into port 2i — I've swapped cables, moved drives in the cage, and I ultimately even got a replacement P600, but it has the same behavior. I tried every combination of card/cache/cable swapping I can think of and the result seems to simply be that anything plugged into port 2i will just light up amber. grrr

I've looked for jumpers or switches or BIOS settings that maybe would help, but I'm really stuck now that I have a 2nd adapter that behaves the same way.

Does anyone have ideas on what could be going on? I greatly appreciate your spare time.

Thank you!
Paul

More info, in case it matters:

• System has 2 power supplies, but only one plugged in at the moment (just saving power for now)
• Neither the BIOS RAID config utility, nor the boot CD ACU(?) utility show that there are more drives plugged in besides the working array of 4 drives. Once the "initializing…" boot sequence for the P600 finishes, the port 2i drives show amber and the config utilities just say "there are no physical drives available" when I try doing things like adding a hot spare, etc. The drives are lit up solid amber before the app even opens up, anyway.
• The drives are all the same, down to the manufactured date.
• Can't think of anything else to add.. hope I've been thorough enough.

I am still unable to discover how to make this work with both ports on the P600, so I have decided to move on the suggestion of ewwhite and I've bought a Smart Array P400 to try. I hope that ends up providing a solution for me to get all 6 drives on-line, but I won't know until next week, after I get the part and get it installed.

I am absolutely willing to continue testing and hopefully figuring out what's going on with the P600 in my configuration (I'm returning one card, but I'll have the other here for testing.) If anyone comes up with more suggestions to try, I'll run the tests and report back. I'd love to patch a "SOLVED!" onto this thread! I hate when things like this get left hanging. Unfortunately, I don't have funds to purchase more drives (SAS/SATA) to see if maybe it's just a weird incompatibility with 1/2 of this card and the consumer drives I'm using.

Thank you VERY much for your responses thus far, ewwhite.

Well, I've bought a P400 card to replace my P600 and it's working great for me. I still don't know what else to think of the P600 2nd port issues, since it was the same with 2 cards. It really makes no sense that the same drives will work on port 1, but not port 2… oh well.

If it turns out anyone adds to this thread with something they'd suggest to try, I would be willing to put the P600 back in to test the theory(ies).

Thanks again to ewwhite for the help. I'll "close" this issue by accepting his post. (The P400 tip rocked. Thanks!)
