Locking the Cache Setting
You can prevent host systems from using SCSI mode select commands to change the
controller’s write-back cache setting. Some operating systems disable write cache. If
cache lock is enabled, the host cannot modify the cache setting. The default setting is
disabled.
This option is useful in some environments where the host system disables the
controller’s write-back cache, resulting in degraded performance.
To lock the cache setting:
1
From the System Menu, select
Configuration
Menu
and press
Enter
.
The Configuration Menu screen displays.
2
Select
Option Configuration
and press
Enter
.
The Option Configuration screen displays.
