Replacing Hard Drives

The hard drives on the server are set up in a Redundant Array of

Independent Disks (RAID) configuration. This allows information to be

recorded across several hard drives. If one hard drive fails, there is

enough information on the other hard drives for the server to continue

functioning. Only one hard drive can be replaced at a time while the

server is running.

If your server is still under warranty, contact Avigilon Technical Support to

replace a failed hard drive: http://avigilon.com/#/support-and-downloads/

If two or more hard drives fail at the same time, contact Avigilon Support

immediately for recovery instructions.

Important: Only replace a hard drive if the hard drive LED indicator and

the Server Administrator displays an error. See LED Indicators on

page 13 and Server Administrator on page 8 for more information.

1. Open the Server Administrator using an Administrator login.

2. In the System Tree on the left pane, select System > Storage >

Perc H710 Mini (Embedded) > Virtual Disks.

a. For the redundant virtual disk, select Check Consistency

from the drop down list and click Execute. Wait until the task

is done before continuing this procedure.
