Using A Raid Device; Maintaining A Raid Device; Replacing Raid Underlying Devices - AudioCodes MP-26 series User Manual

User's Manual
The figure below depicts a successful configuration of two RAID devices as they appear in
the Raid Devices table in the 'File Server' screen. The first is RAID0, consisting of two
underlying partitions (one on each disk), and the second is RAID1, consisting of another
set of underlying partitions. Note that the RAID0 total space is the sum of the two partitions,
while the RAID1 total space is the size of one partition (due to mirroring).

17.2.3.2 Using a RAID Device

When RAID is configured over the existing partitions, these partitions are no longer
independent. It is therefore necessary that you update the location of the system storage
area:
1. In the 'Disk Management' screen, verify that the 'Automatically Create System Storage
Area' check box is selected. If you wish to define the system storage area manually,
clear the check box and enter the name of the designated mount point.
2. Click OK to save the settings.

17.2.3.3 Maintaining a RAID Device

A RAID device differs from a regular partition by not being part of a physical disk. It
therefore resides and is maintained on the device. RAID maintenance is divided into two
aspects:

Maintaining the RAID device itself:
•
In the RAID Device table in the 'Disk Management' screen, click the Edit
of the RAID device; the 'RAID Properties' screen appears in which you can:

♦

Maintaining the partition:
•
In the 'RAID Properties' screen, click the device name; the 'Partition Properties'
screen appears in which you can check and format the RAID partition.

17.2.3.4 Replacing RAID Underlying Devices

Adding or removing a RAID underlying device can only be performed on RAID1 and RAID5
configurations. RAID1 can operate with just one device (although mirroring is unavailable),
and RAID5 can operate with one device less than its original amount of devices.
The names of the RAID underlying devices appear on the 'RAID Properties' screen. Each
device is followed by a status:

Active: The device is controlled by RAID.

Inactive: The device failed to join the RAID array or does not exist.

Faulty: The device joined the RAID array but was marked as faulty due to an error. It
is inactive and should be replaced.
