84 Managing Logical Disks
• Open the Windows Control Panel, select Administrative Tools, and then select Computer
Management.
• On the Windows desktop, right-click the My Computer icon, and then click Manage.
2. In the Computer Management utility’s left pane under Storage, click Disk Management.
Creating a logical disk—MSA storage
The Create New Logical Disk wizard assists with the creation of logical disks from the storage arrays
(subsystems) in your SAN. Use the following procedure to create a logical disk from an HP MSA
1000/1500 or MSA 2000 family storage array. (If your storage array type is EVA, see “Creating a
logical disk—EVA storage,” page 80.)
IMPORTANT: Before you can create a logical disk as a RAID 3, 10, or 50 type on an MSA 2000 family
storage array, you must first create a LUN of that same RAID type using the MSA 2000 family web
management interface: Storage Management Utility (SMU). For instructions, refer to your MSA 2000
family documentation. After you create the LUN with SMU, launch Simple SAN Connection Manager. A
storage pool with the RAID type you just created will be visible. Then you can follow the steps in this
section to create additional LUNs of that RAID type.
IMPORTANT: The following limitations apply to LUN creation for the MSA 2000 family:
• A maximum of 16 virtual disks (disk groups) are allowed per controller.
• All LUNs on a virtual disk must be of the same RAID level.
• You cannot combine SAS and SATA drives in the same virtual disk.
• The minimum and maximum number of disk drives for each RAID level are as follows:
NOTE: The screens depicted in the figures in this section may appear slightly different on your system,
depending on your MSA storage array type (1000/1500 or 2000 family).
To create a logical disk for MSA storage:
1. To access the Create New Logical Disk wizard, choose one of the following options:
• On the Logical Disk Operations menu, click Create New Logical Disk.
• In the navigation pane or in the content pane’s topology map, right-click the subsystem icon to select
a specific MSA subsystem from which to create a logical disk. Then on the shortcut menu, click
Create Logical Disk from Storage Subsystem.
The Create New Logical Disk wizard opens.
2. If no specific subsystem is selected and if there is more than one subsystem in the SAN, select from the
subsystem list the MSA subsystem on which you want the logical disk(s) created, and then click Next.
If this is the first logical disk created on the subsystem, the Create Storage Pool dialog box opens
( Figure 56 ); continue with step 3 . If not, the Select Storage Pool for Logical Disk Creation dialog box
opens ( Figure 57 ); continue with step 4 .
3. If the Create Storage Pool dialog box ( Figure 56 ) opens, follow these steps to create a storage pool:
RAID Level Minimum Drives Maximum Drives
0 2 16
1 2 16
5 3 16
6 4 16
