Maintaining Units Note: These tasks will only be run during scheduled times if they are checked in the Schedule Self-tests section of the Scheduling page. If neither of the tasks is checked, self-tests will never run, even if you have scheduled time slots set. To select self-tests to be performed 1 Choose Management > Schedule from the menu bar. The Scheduling Page appears, showing the schedule for Rebuild Tasks. 2 Select Self-test Tasks from the drop-down list at the top of the page. 3 Check the boxes next to the self-tests you want to be performed. To disable self-tests Unlike scheduling of rebuilds and verifies, scheduling of self-tests is always enabled. To disable self-tests you must either remove all schedule times, or uncheck the tests listed in the Tasks column. Rebuilding Units If a hot spare is specified and a redundant unit degrades, an event notification is generated and the hot spare dynamically replaces the failed drive in the redundant unit without user intervention. The rebuild process will automatically be launched as a background process at the next scheduled time. If scheduling is turned off, the rebuild process will start almost immediately (within a few minutes). If 3DM is running and E-mail notification is enabled, an event notification will be sent to specified users when the rebuild process starts and when it completes. If a hot spare is not specified, or if there is not a hot spare large enough to replace the degraded drive, you can manually replace the drive and start the rebuild process. Manual rebuilds can be started from either 3BM or 3DM, although the rebuild itself only happens when the operating system is running. If multiple drives are faulted in a RAID 10 configuration, the drives are rebuilt simultaneously. In a 4-drive RAID 10 configuration, up to two drives can be rebuilt. In a 6-drive configuration, up to three drives can be rebuilt. In 130 3ware 9000 Series Serial ATA RAID Controller User Guide
