Reasons:
- flogi server not responding correctly
show flogi internal event interface fc x/y
- persistent fcid limit exceeded ( 255 entries with all area unique fcid because
of qlogic hbas)
MDS9513-83-SJ# show run | include "vsan Z" | include fcid | count
where Z is vsan #.
- conflict in persistent fcids ( MDS can't assign the fcid allocated
to WWN)
- # of devices more than 255 if qlogic or devices that need area unique fcid
is allocated
- supervisor failure or module issue, flogi command not reaching the supervisor
or flogi process.
show fc2 internal even errors
these are few causes.

Also a port can get stuck in Initializing in case of OSM/Host
optimized line cards, you need to force set E port and make it dedicated port mode.
I am running
Hardware
cisco MDS 9124 ("1/2/4 Gbps FC/Supervisor-2")
Software
BIOS: version 1.0.6
kickstart: version 3.2(1a)
system: version 3.2(1a)
I am facing NPIV login problem
current conifg
CISCO215# show fcdomain fcid persistent
Total entries 14.
Persistent FCIDs table contents:
VSAN WWN FCID Mask Used Assignment if(for info)
---- ---------------------- -------- ----------- ---- ---------- ----

2 20:02:00:0d:ec:96:fe:41 0x550600 SINGLE FCID YES DYNAMIC fc1/3
Now if fc1/1 interface is shutdown and device 20:18:00:05:33:09:88:c2 tries to login behind fc1/3 it is getting fcid allocation fail
why is this happening?
I am getting following error

You can have this problem when you try to associate a Device Alias to a VSAN that doesn't exis (Through DPVM database ).
show flogi internal info interface fcX/Y
