DL385 G2 not seeing 4 hard disks

[todlarson]

We have an HP DL385 G2 with an HP Smartarray P400 slot 1 and 8 hard drives (7 are in use).  We did a server reboot yesterday and then 4 hard stopped working (partition not visible to ESXi and red LEDs on the drives).  When we do F8 during boot to get into the RAID configuration we see that 4 disks are showing up as "missing" as if that "Port 1I" on the controller is bad.   The server boots fine to ESXi loaded onto logical drive #1.

Please advise on how to recover my logical drive #2?

I reseated the 4 "missing" drives but that didn't help.  Can I replace the P400 controller or something?

Hi,

I guess the issue could be with storage cable or drive backplane.

Try reseating or swapping the cables that connects from controller to backplane.

If you have a spare P400 handy, you could swap that.

Thank You!

I swapped the raid cables and the same 4 disks showed up as "missing" so that proves the cables are good.

I reseated the P400 card, no joy.

I reseated all the disks, no joy.

I completely removed and reinstalled the hard disk backplane, no joy.

As luck would have it we discarded four DL385G2 servers last year and kept this one as a test box so I have no spare hardware.

How would I find the correct part number for the backplane and for the P400 so I can order a replacements?

We found a replacement P400 card and swapped it out, no joy.
