How to identify virtual/physic disk path on X4100?

Hello,

Currently we have a Oracle X4100 ( Solaris 10 ) server with disk failure. Originally our hardware team thought the disk can be hot-swap, when they stood in front of the server, none of the disk failure LED were on, so now we have no idea which disk is the bad one for replacement.

As we remember that although OS is seeing c2t2d0 is the bad disk originally, but it doesn't mean it's the physical disk which is failing.

Therefore, we need some advice how to identify the real failed disk for replacement.

( Note: originally only c2t2d0 shows hardware error in iostat, now is including c2t3d0, "format" is completely hung, "raidctl -l" will show 0.2.0 and hung ... without continuing )

Code:

>iostat -Een

Since "raidctl -l -g 0.3.0 2" hungs here, does it mean we actually have a bad disk at c2t3d0?

Anyway to confirm which disk is the bad disk?

Thank you very much,

SC
