Configuration Scenarios; Viewing Npiv Port Configuration Information - HP AA979A - StorageWorks SAN Switch 2/8V Administrator's Manual

The following example shows the configuration of these parameters:
switch:admin> switchdisable
switch:admin> configure
Configure...
Fabric parameters (yes, y, no, n): [no]
Virtual Channel parameters (yes, y, no, n): [no]
F-Port login parameters (yes, y, no, n): [no] y
Maximum logins per switch: (1..4032) [4032] 2048
Maximum logins per port: (1..255) [255] 126

Configuration scenarios

The actual number of virtual N_Port_IDs accepted per port and per switch is determined by the limits you
set, and also by the limit that is reached first.
For example, if you've set switch.login.perPortMax to 25, and switch.login.perSwitchMax
to 100, then the first 4 ports will accept 25 virtual N_Port_IDs each. However, the fifth port will reject any
more virtual N_Port_IDs because the switch.login.perSwitchMax parameter (100) has been
reached.
If you set switch.login.perPortMax to 50, and switch.login.perSwitchMax to 25, then the
first port requests 50 virtual N_Port_IDs; 25 are accepted, and 25 are rejected. The second port requests
50 virtual N_Port_IDs, but none are accepted, because the switch.login.perSwitchMax limit of 25
has been reached.

Viewing NPIV port configuration information

To view the NPIV capability of switch ports, enter the portCfgShow command. The following example
shows whether or not a port is configured for NPIV:
switch:admin> portcfgshow

NPIV capability
Use the switchShow and portShow commands to view NPIV information for a given port. If a port is an
F_Port, and you enter the switchShow command, then the port WWN of the N_Port is returned. For an
NPIV F_Port, there are multiple N_Ports, each with a different port WWN. The switchShow command
