Communication problem between host and storage devices
The communication problem between host and storage devices is because:
•
•
•
Example:
zoneset name ZoneSet_Host_Storage vsan 100
zone name Zone_Host_Storage vsan 100
* fcid 0x640114 [pwwn 20:00:00:25:b5:00:20:0e] [Host]
Possible Cause
The host or storage port are in the wrong VSAN.
Example:
switch(config)# show fcns database
VSAN 50:
--------------------------------------------------------------------------
FCID
--------------------------------------------------------------------------
0x420000
Solution
Move the storage port to the correct VSAN. (VSAN 100 is the correct VSAN in the example.).
Example:
switch(config)# show flogi database vsan 50
--------------------------------------------------------------------------------
INTERFACE
--------------------------------------------------------------------------------
fc2/2
Total number of flogi = 1.
switch(config)# vsan database
switch(config-vsan-db)# vsan 100 interface fc 2/2
Traffic on fc2/2 may be impacted. Do you want to continue? (y/n) [n] y
switch(config-vsan-db)# show zoneset active vsan 100
zoneset name ZoneSet_Host_Storage vsan 100
zone name Zone_Host_Storage vsan 100
* fcid 0x640114 [pwwn 20:00:00:25:b5:00:20:0e] [Host]
* fcid 0x5a0000 [pwwn 50:0a:09:81:86:78:39:66] [Storage]
