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.
