Overview & Managed Hot Swap Preparation
About REO Disks
CAUTION: If all drives are replaced at once, all data is
lost and the RAID needs to be rebuilt. See your REO
Setup Guide for rebuild help.
REO appliances are equipped with Serial ATA disks
mounted in disk carriers that are accessible through the
front of the enclosure. By using the applicable features in
the REO GUI, you can remove and replace a disk without
powering down the appliance. This is known as
performing a managed hot swap of a disk.
Managed Hot Swap Preparation
1. Make sure that none of the initiators (servers) have
active connections with the appliance.
2. In the REO GUI, locate the disk identification and
removal page associated with the REO software version
in use.
•Version 2.5.0 or later: Internal Disk Management
page.
•Version 2.4.0 or earlier: Physical Volume
Management page.
3. Using the appropriate GUI page, locate the applicable
disk and click the “Remove” button next to it.
NOTE: If you are using REO software version 2.2 or later,
the applicable disk might be listed in the FREE DRIVE
POOL section of the page and might not have a
corresponding Remove button.
a. On the Internal Management or Physical
Volume page, note the disk location.
b. Click the Remove button (if applicable).
c. Click OK when the confirmation message appears.
The managed hot swap preparation is now complete.
