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
SnapServer
s 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.
