Disk Channel Errors MSA2312i MSA2000 SAN appliance

Every couple of days, we get a warning on our MSA2000 StorageWorks SAN. It is Event ID A1026 or A1020 or A909, A874. "A disk channel went to a degraded state. (channel:0)(reason: excessive errors) This is preceded by "Disk Channel error". According to the System Events, it seems to recover very soon after. But I'm looking for what this error means, and why it happens. The disk channel errors that precede it seem to always mention the same enclosure: 1, slot 2 and then a protocol error. Trying to google it is not getting me any results. Please help.

Lee I seem to be getting similiar errors on my MSA2324FC-G2

They are as follows:

Event Log Severity Time Event ID Code Message

2010-07-07 07:27:52 A1511 136 A disk channel went to a degraded state. (channel: 0) (reason: excessive errors)

2010-06-09 08:09:29 A1353 136 A disk channel went to a degraded state. (channel: 0) (reason: excessive errors)


Ive been told to downgrade then upgrade my firmware back to Storage Controller Code Version M110R28.

I really wish I knew when a fix would be out. I don't like the idea of a downgrade and a upgrade. I have gotten responses from, if the SAN still works why worry to the solution I just mentioned.

Re: Disk Channel Errors MSA2312i MSA2000 SAN appliance

in our case, the drive mentioned by the error failed. So this error could mean that the drive is glitchy and going to fail someday. Since replacing the drive, haven't seen these errors since.
