AM456-9025A HP VMA SAN Gateway Installation and Configuration Guide 49
Configuration Overview
Configuring vSHARE is a prerequisite to using a HP VMA SAN Gateway for block storage. The
vSHARE configuration allows you to define sophisticated rules for controlling access to the LUNs
by initiator groups, initiators, or target ports.
Configuring target ports and initiator groups are optional steps in the vSHARE configuration
process. Organizations that do not want to use LUN-masking can control access to LUNs through
ports or switches. LUN masking is an authorization process used to make a logical unit number
available to some hosts and unavailable to others.
To configure vSHARE, complete the following procedures:
1.
Configuring Storage Containers
on page 47. This step initializes the HP VMA-series Array to
manage block storage and create one or more storage containers (partitions) to manage the LUNs. To
format the HP VMA-series Array from vSHARE, the
media init
command is required. This
command enables you to initialize one or more Memory Arrays to support block storage. Once a
Memory Array has been initialized to support block storage, you may create one or more storage
containers on each Memory Array, which may be used to store and manage LUNs.
2.
(Optional) Configuring Target Ports on page 49. This step configures the target ports so they
can control access to LUNs. Configuring target ports is useful for security and bandwidth
management.
3.
(Optional) Configuring Initiator Groups on page 51. This step configures the initiator groups,
adding one or more initiators to each initiator group. You can restrict access to LUNs by
initiator group, or on a per-initiator basis.
4.
Creating LUNs on page 53.
LUNs are created within a storage container that comprises a particular HP VMA-series Array.
A LUN inherits the attributes of the container (HP VMA-series Array) in which it is created.
Note:
As of this release, one container comprises a HP VMA-series Array.
5.
Exporting LUNs on page 56. This required step exports the LUNs to the initiator groups or
initiators via target ports. Only those initiator groups or initiators to which the LUN is
exported may access the LUN. Access may be further restricted to a specific target port.
