7-30 SANRAD V-Switch CLI User Manual
Exposing an iSCSI Target and LUN
The first LUN
assigned to an iSCSI
target must be
LU 0.
A LUN value cannot
be larger than 255.
All CLI names and
aliases are case
sensitive.
A snapshot volume
must be exposed on
the same V-Switch
as the source
volume.
To make a volume accessible to a host, you need to assign a LUN to it,
attach the LUN to an iSCSI target and expose the target. The CLI
command volume expose is used in two ways:
ƒ Create and expose a new target.
ƒ Expose an existing target.
The CLI command volume expose -new creates a new iSCSI target,
assigns a volume LUN and then exposes the new target.
After creating a target and LU0, you can add additional LUNs to the target
using the CLI command volume expose (without the –new switch).
volume expose
If you are working in a V-Switch cluster, each target and LUN must be
configured on both V-Switches in the V-Switch cluster. For more
information on V-Switch clusters, see Chapter 5 “
Introduction to V-
Switch Clusters ”.
If you add or modify identities on a target after its volumes have been
exposed, the access rights will take effect only at the next login for each
iSCSI initiator.
