Managing Logical Disks

SAN Connection Manager automatically retrieves the updated configuration from the subsystem and

refreshes the navigation pane and the topology maps in the content pane to include the new logical

disk(s).

NOTE:

If you present (assign) a logical disk to a Windows system, you can instead use the system’s Disk

Management option to create partitions and assign a drive letter or mount path on partitions.

1.

To access Computer Management, choose one of the following options:
• 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 84.)

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: SMU. For instructions, refer to your MSA 2000 family documentation. After you

create the LUN with SMU, launch 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.
