A service host is connected to a storage device through Fibre Channel SAN. However, the service host cannot detect mapped LUNs after scanning. Which of the following are possible causes?
A.
The Fibre Channel module on the service host is faulty.
B.
No multipathing software is installed on the service host.
C.
Zones are incorrectly configured.
D.
The storage network is blocked by the firewall.
A - If a fiber module is defective, then there is always that of the second controller
B - Without multipathing software, we would see the same LUN several times
C - Without Zoning configuration, it is impossible to connect a LUN
D - The FCP flow has not been managed by a Firewall unless it is iSCSI or RoCE which is not the case here
So answer C is the most consistent
the most likely possible causes are:
A. The Fibre Channel module on the service host is faulty
C. Zones are incorrectly configured
D. The storage network is blocked by the firewall
B is less likely to be the direct cause of the issue described but is still important for overall functionality and redundancy
This is a multiple choice question. A,B and C are correct.
