inside a VMA Array. In many systems, a LUN may be referred to as a volume or

logical unit.

On the host system (initiator), the LUN appears as a local SCSI disk. The host may

format and partition the LUN. The target, or storage system, sees the contents of

the LUN as a set of blocks of arbitrary data.

Every LUN is created within a container. A container is an addressable partition of

one or more VMA Arrays. When a LUN is created, it is assigned to a specific

container and inherits the attributes of the container.

vSHARE implements LUNs at a minimum of 1GB increments with the ability to

configure up to 1024 LUNs per HP VMA SAN Gateway.

LUN Creation Overview

1. From the CLI, enter into Enable mode using the enable command and then

Config mode using the

configure terminal command.

2. All LUNs are created and managed within a container. To view the available

containers, use the show containers command.

Check the size of the containers. LUNs are implemented in 1GB increments;

the size of the container may restrict the number of LUNs that may be created.

3. Enter the lun create command to create LUNs within a container.

The command creates 20 LUNs of equal size in the container. Use the

nozero

option to ensure that the data is not zeroed-out, which could take considerable time

depending on the size of the container.
