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.
