There are "COMMAND TIMEOUTS" and after while controller is loosing one of drives, then another. This is hardware problem and we are waiting for IBM (while they write firmware) to replace 30 such "bad" disks. Other SATA and SAS disks works fine. btw, if you are using gjournal, BIO_FLUSH is not supported by aac. But it's more like warning, not error. -- regards, Artis Caune <----.
