COMMAND
createvlun
DESCRIPTION
The createvlun command creates a Virtual Logical Unit Number (VLUN) template that
enables export of a Virtual Volume (VV) has a SCSI VLUN to one or more host(s). A SCSI VLUN is
created when the current system state matches the rule established by the VLUN template.
There are four types of VLUN templates:
■ port presents - created when only the node:slot:port are specified. The VLUN is visible
to any initiator on the specified port.
■ host set - created when a host set is specified. The VLUN is visible to the initiators of any
host that is a member of the set.
■ host sees - created when the hostname is specified. The VLUN is visible to the initiators
with any of the host’s World Wide Names (WWNs).
■ matched set - created when both hostname and node:slot:port are specified. The
VLUN is visible to initiators with the host’s WWNs only on the specified port.
Conflicts between overlapping VLUN templates are resolved using prioritization, with port
presents templates having the lowest priority and matched set templates having the highest.
