Hello,
I have a problem with the following OpenSolaris Server after adding four new
harddrives and one hot-spare (all hdds are Samsung HD203WI), the server hangs
when IO Load raises.
Server:
Mainboard: Supermicro X8DT3-F
SAS Controller: 3Ware 9690SA-4I
CPU: Intel Xeon 5500
Here are some informations about the drive configuration:

After spending some time in google I tried the following "workarounds" wich
didn't works... :
Some options like in /etc/system:
set cpupm_enabled = 0
set idle_cpu_no_deep_c = 1
and /etc/power.conf:
cpu_deep_idle disable
I hope u guys can help me solving this Problem ;)
