Managing Arrays and Spares 1 Click the Array icon and observe the Disk icons of the array members on the left side of the screen. One of the icons should look like this failed. , indicating that the disk has 2 Right-click the icon and then select Blink from the drop-down menu to blink the drive light on the failed disk. 3 Observe which drive light is blinking. This is the disk that you need to replace. If no lights are blinking, this could mean one of the following: a The disk is still connected but has failed so badly that it cannot respond to the Blink command. Try blinking the drive lights of the array disks that have not failed. You may be able to determine by a process of elimination which disk has failed. b The disk has been removed or its power cord or SCSI cable has been disconnected. If an array disk has been disconnected or removed but the server has not been rebooted, the icon for this disk will still appear in the Storage Configuration window. If you know that the disk was disconnected accidentally and has not actually failed, reconnect the drive and issue the Rescan command. You can reconstruct the array by issuing the Reconstruct command. If the system has been rebooted since the disk was disconnected, the disk will not appear. To determine if a disk is "missing" from an array, right-click the array icon, select Information from the drop-down menu, and read the Status field at the top of the Array Information dialog box. If this field says Missing member, a disk is missing from the array. c The disk does not have an LED that indicates I/O activity. 4 If the array enclosure supports hot swapping1, remove the failed drive. 10-3
