Locking the Cache Setting
This function allows the user to prevent host systems from using SCSI mode select commands
to change the controller's write-back cache setting. Some operating systems disable write
cache, resulting in degraded performance. If cache lock is enabled, the host cannot modify
the cache setting (default setting is disabled).
This option is useful in environments where the host system disables the controller's write-
back cache, resulting in degraded perfomrance. In a dual controller configuration (Active-
Active or Active-Passive mode), a change to this setting on either controller is automatically
updated on the other controller.
To lock the cache setting:
1. Select Configuration Menu from the System Menu and press Enter.
The Configuration Menu should now display (Figure 31).
2. Select Option Configuration and press Enter.
The Option Configuration screen should now display (Figure 32).
