RS2BL040 Raid Card error message

[OSEN]

Hi,

I get following error message on my dmesg output. Can someone guide me on how to debug what is the exact problem here.

Omer,

It looks like normal powersave to operation transitions.

Sense 2/04/02 means: LOGICAL UNIT NEEDS INITIALIZE COMMAND (START UNIT). You see for physical disk 0c that the disk has transitioned from powersave immediately after the 2/04/02 message for that drive (need initialize command (start unit)). Do you see transitioned from powersave messages for the other PDs later?
