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

[Mark Salyzyn <Mark_Salyzyn@xxxxxxxxxxx>]

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.

Sincerely -- Mark Salyzyn
