Disks and Units Hot Swapping Disk Drives The term hot swap refers to the ability to remove and add components to a system without the need to turn off the server or interrupt client access to files. When to Hot Swap Disk Drives When available storage space is not at a premium, most administrators prefer to configure a RAID with a hot spare that automatically takes the place of a failed drive. This solution assures that client access to file systems is not interrupted. In environments where configuring a hot spare is not possible, you may need to hot swap a drive. Hot Swapping Disk Drives You can hot swap disk drives on SnapServer RAID 1, 5, 6, or 10 by following the two basic steps outlined next: 1 Remove the failed drive from its bay, and insert the new drive. The procedures for the physical removal and replacement of a disk drive for SnapServers are explained in the following sections. Note If you have enabled the automatic incorporation of an unused disk feature, the drive you insert (a raw drive, a drive with a non-GuardianOS partition, or an unassigned GuardianOS-partitioned drive) will be automatically incorporated into the RAID. Skip Step 2. 2 Configure the new drive as part of the RAID. When you remove a drive from a SnapServer, the affected RAID transitions to degraded mode. It remains in degraded mode until the newly inserted drive is configured as a member of the RAID via the Administration Tool. For details on this procedure, see "Adding Disk Drives to a RAID" on page 68. Replacing a Disk Drive on a SnapServer N2000 or E2000 When the bottom LED on the disk drive is red, the drive has failed or is not working properly. 1 Remove the bezel by pressing the latch on the left side of the bezel (as you face it) and gently pulling to release the left side from the chassis. 2 With the left side open, pull the bezel to the left to release the right side pegs and remove the bezel. 70 SnapServer Administrator Guide
