DESCRIPTION
Use this command to enable or disable NPIV functionality on a port and to configure the maximum
number of logins for this port. Changes made by this command are persistent across switch reboots and
power cycles.
N_Port ID Virtualization (NPIV) enables a single Fibre Channel protocol port to appear as multiple,
distinct ports, providing separate port identification within the fabric for each operating system image
behind the port as if each operating system image had its own unique physical port. NPIV assigns a
different virtual port ID to each Fibre Channel protocol device without impacting your existing hardware
implementation. The virtual port has the same properties as an N_Port and is therefore capable of
registering with all fabric services.
The following conditions must be met for a switch port to respond to NPIV requests from an NPIV device:
NPIV capable
NPIV capability is a switch blade or port attribute that is required for NPIV
functionality. Some blades within a switch, or some ports within a switch or blade,
may not have NPIV capability. NPIV functionality cannot be enabled on such ports
and they do not respond to NPIV requests.
NPIV enabled
NPIV functionality must be enabled on a port for it to respond to NPIV requests.
NPIV is enabled by default. It can be selectively disabled or re-enabled on
specified switch ports using this command.
NPIV HA
To enable NPIV functionality on dual-CP systems, NPIV-enabled firmware must
be running on both the active and the standby CPs. This requirement does not
apply to single-CP systems.
Use the
--setloginlimit
option to configure the number of permitted logins per NPIV port. Up to 255
virtual port IDs are allocated per NPIV port, which means each NPIV port can support up to 255 logins.
The number of logins you can configure per port is between 0 to 255. The default is 126 per port. The
sum of all configured per-port login maximum values cannot exceed the total number of logins set for the
switch with the
configure
command.
As of Fabric OS v.6.4.0 you can no longer use the
configure
command to set the NPIV port login limit on
a per-switch basis. However, the maximum number of logins per switch is still set and enforced by the
configure
command. Use
configure
to display the current setting.
