Controller policies are shown at the bottom of the Controller Settings page. • Auto Rebuild. Determines whether the Auto Rebuild policy is enabled or disabled.

A recommendation is then made as to whether an update is needed, and you are asked to confirm whether you want to continue. If you confirm that you want to continue, the new firmware image is downloaded to the specified controller. A reboot is required for the new firmware image to take effect. Example: //localhost> /c0 update fw=/tmp/prom0006.img Warning: We strongly recommend backing up your data before updating the firmware. Updating the firmware can render the device driver and/or management

Models 9500S, 9550SX, and 9590SE The quiet attribute turns off interactive mode. /cx/ux set identify=on|off This feature only applies to 9550SX, 9590SE, and 9650SE model controllers. This feature requires an enclosure that uses an integrated AMCC/3ware CCU (chassis control unit). (Check the 3ware web site for a list of chassis vendors that support enclosure services, as they become available.) For additional information about enclosure-related commands, see “Enclosure Object Commands” on page 87

JBOD A JBOD (acronym for “Just a Bunch of Disks”) is an unconfigured disk attached to your 3ware RAID controller. JBOD configuration is no longer supported in the 3ware 9000 series.

JBOD units are not fault tolerant and therefore not recommended for high availability systems unless additional precautions are taken to prevent system hangs and data loss. Chapter
