NOTICE: Qlogic qlc(0): Loop ONLINE

Sun Blade 1000 or Sun Blade 2000 gets Loop OFFLINE ONLINE notices periodically.

The systems seems to hang for about 10 to 20 seconds before being able to access it after idle periods.

What is happening is powerd is spinning down the disks. The time that it seems to hang is when the disks are spinning back up.

There are two ways to fix this problem.

1. To disable power management (powerd) altogether, perform the following:

#cd /etc/rc2.d

#mv S85power s85power

#init 6

2. Start the Power Manager GUI (DTpower)

Select the "More" option

Select the "Disks" option and change the setting to "Always On"

Change "Device Idle Time" to "Always On"

Click "OK", The new settings should not spin down the disks.
