5.6 Controlling Host Access to the
Galaxy 65’s Write-back Cache Setting
You can prevent host systems from using SCSI mode-select commands to change the Galaxy 65
Subsystem’s write-back cache setting. Some operating systems disable write cache. If cache lock is
enabled, the host cannot change the cache setting. The default setting is disabled.
This option is useful in some environments where the host system disables the Galaxy 65 Subsystem’s
write-back cache, resulting in degraded performance.
To lock the cache setting:
1
From SAM, select
Manage Galaxy 65 Subsystem > General Config > Option Configuration
.
The
Option Configuration
page displays.
2
Select the Host Control of Write-back Cache option you want.
3
Click
Change Options
