igroup addto Command

The

igroup addto command adds one or more initiators to a group.

Syntax

[no] igroup addto <igroup_name> initiators [initiator_name …]

The following command adds three initiators to the initiator group named FINANCE:

The following command removes the initiator wwn.20:20:20:20:20:20:20:20 from igroup

FINANCE and preserves the other two initiators (wwn.20:20:20:20:20:20:20:21

wwn.20:20:20:20:20:20:20:22).

Creating LUNs

The fourth step in configuring the vSHARE system is to create the LUNs. In vSHARE, LUNs are

addressable subsets of the flash memory within the container that comprises a HP VMA-series

Array. In many systems, a LUN may be referred to as a

volume or logical unit.

Note: As of this release, one container comprises a HP VMA-series Array.

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

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

1024 LUNs per HP VMA SAN Gateway.

LUN Creation

To create a LUN, complete the following steps:

igroup_name

The name is alphanumeric only.

initiator_name

The initiator_name must be prefixed with “wwn.”
