MSA2012fc: I/O error

Hi, I've got some strange behavior on my msa2012fc.

There are 8 blades with rhel, with mounted rootfs located on msa. All partitions remount in ro immediately after the start. MSA shows that all drives status is OK. I've checked FC cables, mezzanine cards, it all Ok too.

 

But,

in dmesg:

 

end_request: I/O error, dev sda, sector 30506117
printk: 159 messages suppressed.
Buffer I/O error on device dm-0, logical block 3787111
lost page write due to I/O error on dm-0
sd 0:0:0:0: SCSI error: return code = 0x08000002
sda: Current: sense key: Aborted Command
Add. Sense: Scsi parity error

 

in msa debug log:

THU JUL 01 08:51:37(0ts) closeSocket: close of socket 31 returned 0
THU JUL 01 08:53:02(0ts) InterMcIpClientInit: connect() returned error: S_errno_ETIMEDOUT

THU JUL 01 08:55:52(0ts) InterMcIpClientInit: connect() returned error: S_errno_ETIMEDOUT

 

How else I can diagnose what is connected with this problem?
