Chapter 5: Monitoring and Managing one physical drive, disappears from the interface if the physical drive is removed or fails. Since these logical drives are not fault tolerant, the data stored in the logical drive is no longer accessible. If one physical drive fails, all of the data on the logical drive is lost. You must replace the failed drive. Then, if the logical drive had more than one physical drive, delete the logical drive, and re-create it. Restore the data from a backup source. If you created a backup drive for your RAID Ready logical drive, the use the backup drive to restore the data. See "Backing up a RAID Ready Logical Drive" on page 68. When a Physical Drive Fails The following will occur when a physical drive fails or goes offline: • The Controller's audible alarm, if enabled, will sound. See page 49. • RAIDXpert reports the condition in Tree View, with popup messages and, if Event Notification is set up, email messages. See page 36. • If you have a RAID 1 or 5 logical drive with a hot spare drive properly configured, the logical drive will automatically rebuild itself using the spare drive. See pages 49 and 89. In the example above, amber ! icons appear over the Logical Drive View and Logical Drive icons. Click Logical Drive View or the Logical Drive to verify the condition of the logical drive. 85
