Viewing Controller Policies in 3DM
You can view the current state of controller policies in 3DM, in the Other Controller Settings section of the bottom of the Controller Settings Page.
Changes to these policies can only be made in 3ware BIOS Manager (3BM).
- Number of drives per spinup: Number of drives that will spin up at the same time when the controller is powered up, if staggered spinup is enabled. From 1 to x, depending on the number of ports on the controller.
- Delay between spinup: The delay in seconds between drive groups that spin up at one time on this particular controller.
- Export unconfigured disks: This setting indicates whether JBOD disks should be exported to the operating system. JBOD configuration is no longer supported in the 9000 series controller, so by default, this setting is disabled. If you have a JBOD configuration from a 7000/8000 controller that you want to use on the 9000 controller, this setting can be enabled.
- Disable write cache on unit degrade: Indicates whether write cache will be automatically disabled on a unit if it becomes degraded. When Yes, the unit write cache and the disk drive write cache will be disabled if the unit degrades. This setting has no effect on non-redundant arrays. Write cache will be automatically re-enabled when the unit returns to normal.
When No, the unit and disk drive write cache will remain enabled (if it is enabled), in the event that the unit degrades.
