Other Controller Settings

The Other Controller settings displays information about additional settings,

some of which can only be changed in the BIOS (3BM).

Auto Rebuild. The Auto Rebuild policy determines how the controller

firmware will attempt to rebuild degraded units.

When Auto Rebuild is disabled, only spares will be used to automatically

rebuild degraded units. When Auto Rebuild is enabled, the firmware will

automatically select drives to use for rebuilding a degraded unit using the

following priority order.

• Smallest usable spare.

• Smallest usable unconfigured (available) drive.

• Smallest usable failed drive.

For additional information, see “Setting the Auto Rebuild Policy” on page 91.

Auto-Carving. Auto-carving can be enabled or disabled by selecting the

appropriate radio button.

When this feature is enabled, any unit that is over a specified size (known as

the carve size) will be broken down into multiple volumes of that size, plus a

remainder volume. The default carve size is 2048 GB (2 TB). For example,

using the default carve size, if the unit is 2.5 TB then it will contain two

volumes, with the first volume containing 2 TB and the second volume

containing 0.5 TB. If the unit is 5.0 TB then it will contain 3 volumes, with

the first two volumes containing 2 TB each and the last volume containing

1TB. If a specific Boot Volume was also specified in 3BM, the first volume

will be the size specified for the Boot Volume, and then the carve size will be

applied to the remainder of the unit.

Carve Size. Sets a size for dividing up units into volumes when Auto-Carving

is enabled. This setting can be between 1024 and 2048 GB.

Number of Drives Per Spin-up. Number of drives that will spin up at the

same time when the controller is powered up. (This setting only applies when

the feature is supported by the disk drives.)

Delay between Spin-ups. The delay time (in seconds) between drive groups

that spin up at one time on this particular controller.

Export Unconfigured Disks. By default, this setting is No. If you have

individual drives attached to a 9000-series 3ware RAID controller that you

want to make available to the operating system, it is recommended that you

configure them as Single Disk units.

Number of Controller Phys. The number of phy connections possible on the

controller. The 3ware 9690SA RAID controller has 8 phys.
