Which command is used to determine if a host has logged in to the Fibre Channel fabric?
A. show flogi database
B. show system fc login
C. show npv flogi-table
D. show npv fcns database
E. show interface vfc X flogi
F. show interface flogi
Correct Answer: A
Explanation/Reference:
In a Fibre Channel fabric, each host or disk requires an FCID. Use the show flogi database command to verify if a storage device is displayed in the Fabric login (FLOGI) table as in the examples below. If the required device is displayed in the FLOGI table, the fabric login is successful. Examine the FLOGI database on a switch that is directly connected to the host HBA and connected ports.
Examples
The following example displays details on the FLOGI database.
switch# show flogi database
Total number of flogi = 6.
