Exporting LUNs

The fifth step in configuring the vSHARE HP VMA SAN Gateway is to export the LUNs to an

initiator. The LUN must be exported before it may be accessed over block protocols.

Note: vSHARE LUNs are defined and saved within the Arrays themselves. vSHARE LUN export

records are, however, managed and stored within the vCLUSTER configuration database owned by

the master node.

Access to LUNs may be restricted to a specific initiator group, initiator, or target port when the LUN

is exported using the

lun export command.

• The optional

[igroup | initiator] parameter identifies the initiator group or initiator

that may access the LUN.

• The optional

[port] parameter identifies the target that may access the LUN.

A LUN ID is a SCSI identifier which may be used to differentiate between devices on the same

target port. By default, vSHARE automatically assigns LUN IDs to LUNs when they are exported

to an initiator group or initiator.

vSHARE optionally enables you to assign a special, user-defined LUN ID to a vSHARE LUN when

you export LUNs to an initiator group or initiator. User-defined LUN IDs may make it easier

differentiate between LUNs. If you do assign user-defined LUN ID, it is recommended that you

specify a number below 255, as some operating systems (for example, Windows) will only discover

LUN IDs between 0 and 254. LUNs cannot be exported if they are assigned an existing LUN ID;

an error message is returned and the export fails.

container Displays only the LUNs within a specific container.

name Displays a specific LUN.

count Displays LUNs with active sessions and their count.

reserved Displays LUNs with SCSI reservations.

serial Displays the serial numbers for each LUN.

sessions Displays the sessions accessing a particular LUN.
