Troubleshooting Appendix A This appendix provides troubleshooting instructions. TABLE 10 Problem Troubleshooting Cause Solution Switch is not in Access Gateway mode NPIV disabled on Edge switch ports Need to reconfigure N_Port and F_Ports LUNs are not visible Switch is in Native switch mode Disable switch using the switchDisable command. Enable Access Gateway mode using the ag --modeenable command. Answer yes when prompted; the switch reboots. Log in to the switch. Display the switch settings using the switchShow command. Verify that the field switchMode displays Access Gateway mode. Inadvertently turned off On the Edge switch, enter the portCfgShow command. Verify that NPIV status for the port to which Access Gateway is connected is ON. If the status displays as "--" NPIV is disabled. Enter the portCfgNpivPort port_number command with the enable operand to enable NPIV. Repeat this step for each port as required. Default port setting not adequate for customer environment Enter the portCfgShow command. For each port that is to be activated as an N_Port, enter the portCfgNport port_number command with the 1 operand. All other ports remain as F_Ports. To reset the port to an F_Port, enter the portCfgNpivPort port_number command with the disable operand. Zoning on fabric switch is incorrect. Port mapping on Access Gateway mode switch is incorrect. Cabling not properly connected. Verify zoning on the Edge switch. Verify that F_Ports are mapped to an online N_Port. See "Access Gateway default port mapping" on page 12. Perform a visual inspection of the cabling, check for issues such as wrong ports, twisted cable, or bent cable. Replace the cable and try again. Ensure the F_Port on AG module is enabled and active.

Appendix
A
Troubleshooting
This appendix provides troubleshooting instructions.
TABLE 10
Troubleshooting
Problem
Cause
Solution
Switch is not in Access
Gateway mode
Switch is in Native switch mode
Disable switch using the
switchDisable
command.
Enable Access Gateway mode using
the
ag
--
modeenable
command.
Answer yes when prompted; the switch reboots.
Log in to the switch.
Display the switch settings using the
switchShow
command. Verify
that the field
switchMode
displays Access Gateway mode.
NPIV disabled on Edge
switch ports
Inadvertently turned off
On the Edge switch, enter the
portCfgShow
command.
Verify that NPIV status for the port to which Access Gateway is
connected is ON.
If the status displays as “--” NPIV is disabled. Enter the
portCfgNpivPort
port_number
command with the
enable
operand to
enable NPIV.
Repeat this step for each port as required.
Need to reconfigure
N_Port and F_Ports
Default port setting not adequate for
customer environment
Enter the
portCfgShow
command.
For each port that is to be activated as an N_Port, enter the
portCfgNport
port_number
command with the
1
operand.
All other ports remain as F_Ports.
To reset the port to an F_Port, enter the
portCfgNpivPort
port_number
command with the
disable
operand.
LUNs are not visible
Zoning on fabric switch is incorrect.
Port mapping on Access Gateway mode
switch is incorrect.
Cabling not properly connected.
Verify zoning on the Edge switch.
Verify that F_Ports are mapped to an online N_Port. See
“Access
Gateway default port mapping”
on page 12.
Perform a visual inspection of the cabling, check for issues such as
wrong ports, twisted cable, or bent cable. Replace the cable and try
again. Ensure the F_Port on AG module is enabled and active.
