adaptec 3405 + 4 sas disks: synchronize_callback: synchronize failed, status = 226

Hello,

I'm running 2.6.24.3 kernel and I'm getting few error messages comming from aacraid driver. Hardware is adaptec 3405 running firmware 15728 + 4 SAS 300GB harddisks configured in single raid10 array.

[167674.161866] synchronize_callback: synchronize failed, status = 226
[168977.738031] synchronize_callback: synchronize failed, status = 226
[172180.752140] synchronize_callback: synchronize failed, status = 226
[177494.855145] synchronize_callback: synchronize failed, status = 226
[189594.477223] synchronize_callback: synchronize failed, status = 226
[191411.881236] synchronize_callback: synchronize failed, status = 226
[217130.596663] synchronize_callback: synchronize failed, status = 226
[219236.032362] synchronize_callback: synchronize failed, status = 226

What does 226 mean and what does it indicate (serious problem?) ?

ps. would be good if prefix was added to these messages to know where these come from

226 means CT_ERROR, a generic response to the CT_FLUSH_CACHE command to the controller when the action could not be performed.

The action is to flush all the controller's cache to the targets in response to a SCSI SYNCHRONIZE_CACHE command. I expect that you are running with a degraded array, or incompatible drives?

Make sure your drive and controller firmware is as up-to-date as possible.

It's in "Optimal" state and I have no idea which drives are "incompatible". Is this list published somewhere (I was looking at 3405 download section at adaptec.com)?

Controller firmware is up to date. Disks firmware is 002 according to arcconf, unfortunately seagate doesn't seem to publish firmware on their site, so I don't know if it's old or new.
