Figure 49. 3BM Policy Control Screen Exporting JBOD Disks By default, JBOD disks (unconfigured disks) connected to the 3ware RAID controller are not exported to the operating system. This means that any drives you leave unconfigured are not seen by the operating system, and cannot be used for storage. When Export JBOD Disks is set to No, you make individual disks available for use by configuring them as Single Disks. If you want unconfigured disks to be available on your computer, you can change this setting in 3BM or using the CLI. Note: It is recommended that JBODs not be made available to the operation system. The advantages of working with configured Single Disks over JBOD are: „ If interrupted, a single disk media scan will continue from where it left off, while a JBOD media scan must restart from the beginning. „ Single disks can take advantage of the controller caching and configuration is persistent. „ Single disks will be able to be migrated to redundant units in the future (e.g. A single disk will be able to be mirrored to another drive, creating a RAID 1 array). www.3ware.com 119
