Making Global Physical Drive Settings (CLU)
All physical drive settings are made globally, except for setting an alias, which applies to individual
drives.
To make global physical drive settings:
1. Main Menu >> Physical Drive Management >> Global Physical Drives Settings
2. Change the following settings as required.
• Highlight Write Cache and press the spacebar to
toggle between Enabled and Disabled.
• Highlight Read Look Ahead Cache and press the spacebar
to toggle between Enabled and Disabled.
• Highlight MediumErrorThreshold and press the backspace key to
remove the current value, then type a new smaller value.
• Highlight DMA Mode and press the spacebar to toggle
through UDMA 0 to 6 and MDMA 0 to 2.
3. Press Control-A to save your settings.
See “Viewing Physical Drive Information” below to determine which functions your physical
drives support.
Medium Error Threshold is the number of bad blocks tolerated before the controller marks
the drive as Dead. The default setting is 64 blocks. A setting of zero disables the function.
When disabled, no drives are marked ofine even when errors are detected.
