Configuring Virtual Disks for DPM

Configuring Virtual Disks for DPM
For DPM to use additional hard disks, the disk drives must be configured into
one or more RAID 5 virtual disks. Creation of the RAID virtual disks is
accomplished using OpenManage Server Administrator (OMSA).
Use these guidelines when configuring virtual disks:
• Configure all DPM virtual disks as RAID Level 5.
• RAID 5 virtual disks require a minimum of three physical disks.
• RAID 5 virtual disks should have no more than eight disks (excluding the
optional global hot spare).
• Configure an optional global hot spare disk.
• Ensure the size of each virtual disk does not exceed 1.8TB.
• Any number of virtual disks can be created from the RAID disk group.
• Virtual disks used by DPM must not contain formatted OS partitions.
Configuring Virtual Disks and Hot Spares with
OMSA
Refer to the “Storage Management Tasks” section of the Server Administrator
User’s Guide to learn how to create virtual disks on the newly added physical
disks. This section also provides instructions for creating optional global hot
spares.
Example: Using OMSA to Configure Virtual Disks
The server administrator uses OMSA to create a virtual disk from the five
physical disks within the MD1000 that have been attached to the DP500
system. The series of steps below show how a system administrator would
create the 1TB RAID 5 virtual disk needed by DPM’s storage pool to support
the additional protected servers.
