3DM 2 Reference encountered during a rebuild. When this policy is not set, a rebuild will abort upon encountering an ECC error and the unit will be set back to Degraded. Since this option could result in the loss of some source data in the event of source errors, select this option only if you want to ensure that a rebuild will complete successfully without manually intervention. If the rebuild fails and Continue on Source Error During Rebuild is not selected, then you have the option to start a rebuild manually. It is recommended that a file system check be executed when the rebuild completes. Note: The policy Continue on Source Error During Rebuild is equivalent to the "Force continue on source errors" option in 3DM v 1.x and the "ignoreEcc" option in the CLI. Unit Names On 9000-series controllers, units can be assigned names. A name can be assigned when the unit is created and can be changed from this screen. For additional information, see "Naming a Unit" on page 114. Other Controller Settings For 9000-series controllers, the Other Controller settings displays information about additional settings, most of which can only be changed in the BIOS (3BM). For more information see "Setting Policies for a Controller through 3BM" on page 76. This section does not appear for 7000- and 8000- series controllers. 2TB 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 2TB will be broken down into multiple volumes of 2TB each, plus a remainder volume. For example, if the unit is 2.5 TB then it will contain two volumes, with the first volume containing 2TB 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 2TB each and the last volume containing 1TB. 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 and has been enabled in 3BM.) Delay between Spin-ups. The delay time (in seconds) between drive groups that spin up at one time on this particular controller. Export JBOD (Unconfigured) Disks. Indicates whether unconfigured disks (JBODs) should be exported to the operating system. By default, this setting is disabled and JBOD drives are not exported to the operating system. For more information about this feature, see "Exporting JBOD Disks" on page 77. www.3ware.com 55
