General SAN troubleshooting steps
Obtain information on problems in your fabric.
Step 1
Verify physical connectivity between your switches and end devices.
Step 2
Verify registration to your fabric for all SAN elements.
Step 3
Verify the configuration for your end devices (storage subsystems and servers).
Step 4
Verify end-to-end connectivity and fabric configuration.
Step 5
NPV
NP Uplink ports on NPV edge switch are stuck in initializing state
NP uplink ports connected to the core NPIV switch do not come online and are stuck in an initializing
state.
Possible Cause
The core switch might not have been enabled for NPIV.
Example:
switch(config-if)# sh int fc2/2
fc2/2 is down (Initializing)
Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
Port WWN is 20:42:00:0d:ec:a4:3b:80
Admin port mode is NP, trunk mode is on

Check the status of the NPV external interfaces.
Check that the NPIV is enabled on the core switch.
Example:
switch(config-if)# sh npv status
npiv is disabled
disruptive load balancing is disabled
External Interfaces:
====================
Interface: fc2/1, State: Failed(NPIV is not enabled in upstream switch)
Interface: fc2/2, State: Failed(NPIV is not enabled in upstream switch)
Interface: san-port-channel 200, State: Down
If NPIV is disabled, then enable NPIV on the core switch.
Example:
switch(config)# feature npiv
