I have a single bus with 12 Drivers ( 2 Fully equipped Sun Multipacks ).
If i freshly turn on the system (including multipacks) the disks seem
not to spin up. The Kernel (normally spinning up disks not spun up)
just reports an error ...
---------schnipp------------------
scsi1 : channel 0 target 3 lun 0 request sense failed, performing reset.
SCSI bus is being reset for host 1 channel 0.
qlogicpti : Resetting SCSI bus!
---------schnapp------------------
Then the system seems to be dead (Waited at least 10 Minutes)
After waiting some time for all disks spininng up, and rebooting
everything is ok.
This is quite annoying for a non-7x24 system ...
dmesg output ...
