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. AMCC recommends that you use Single Disk as a replacement for JBOD, to take advantage of advanced features such as caching, OCE, and RLM. 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

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

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

Controller policies are shown at the bottom of the Controller Settings page. • Auto Rebuild. Determines whether the Auto Rebuild policy is enabled or disabled. When disabled, degraded units can only be rebuilt with designated spares. When enabled, the controller firmware will attempt to rebuild a degraded unit if there is no spare, using either an available drive or a failed drive. • Auto-Carving. Determines whether the auto-carving policy is enabled or disabled. When it is enabled, any unit lar
