Disk channel errors and I/O Timeouts on MSA2324fc

Hi there,

We've got some serious Problems on our MSA2324fc.
Our logs are full with error messages like these:
Disk channel error. (channel: 0, ID: 11, SN: 3SE0SBTW00009003NHE7, enclosure: 1, slot: 12): Protocol Error CDB:Rd 0000be00 0080

and these:
Disk channel error. (channel: 0, ID: 11, SN: 3SE0SBTW00009003NHE7, enclosure: 1, slot: 12): I/O Timeout CDB:Rd 035c3660 0010

sometimes these:
An error was detected by a disk drive. (disk: channel: 0, ID: 11, SN: 3SE0SBTW00009003NHE7, enclosure: 1, slot: 12)(Key,Code,Qual:0xB,0x4B,0x3)(CDB:Rd 035617c0 0030)(Info:0x035617ED)(CmdSpc:0x0, FRU:0x6, SnsKeySpc:0x0)(Aborted Command, ack/nak timeout)

and even these: (note that we only use 12 disks, out of 24 possible. what's slot 32 then?)
Disk channel error. (channel: 0, ID: 31, SN: 3CL903C333, enclosure: 1, slot: 32): Protocol Error CDB:1c0102010800

The errors come up with all different slots, note just one or 2 disks, and this as soon as we generate traffic on our ESX VMs.
When installing Exchange in a VM, ESX can even freeze.
The Vdisk and Volume seem to be clean.

Here's our config:
1 MSA2324fc with 2 controllers
2 DL380G6 with 2 QLogic HBAs HP81Q (QLE2560 aka Part Nr: AK344A)each
ESX 4 vSphere fully patched

Of course the latest drivers are on the MSA as well (M110R21-01).
Patches we already installed:
ESX400-200906001.zip
ESX400-200907001.zip
ESX400-200909001.zip

Any idea what could cause this?

That sounds like a problem in a back-end's common component - e.g. bad or improper seated SAS cable, bad I/O module.

Hello,

There are no SAS cables, cause we have FC connections. What do you mean by bad I/O module ? Do you think that our newly purchased MSA2324FC could have non working controllers ?

Thanks for further help.

> There are no SAS cables, cause we have FC connections.

I was talking about the SAS back-end, not the FC front-end and I thought you were using an expansion box.

Anyway, yes, it sounds like the system has an internal hardware problem.
