AM456-9026A HP VMA SAN Gateway User’s Guide 103
Note: As of this release, one container comprises a HP VMA-series Memory Array.
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, and each container comprises a HP VMA-series Memory
Array. vSHARE implements LUNs at a minimum of 1GB increments with the ability to configure
up to 1024 LUNs per SAN Gateway.
LUN Creation
To create a LUN, complete the following steps:
1. From the CLI, enter into Enable mode using the enable command and then Configure 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.
Typically, fewer than 100 LUNs would be created within a container; however, the creation of up
to 1024 LUNs is supported per container.
