Correcting Link Failures
10
Some fabric devices have problems with loop initialization. If this is evident, enter the
portCfgPort port #, 1 command.
To correct a port that has come up in the wrong mode
1. Enter the switchShow command.
2. Refer to the comment fields (refer to Table 10-6) and follow the suggested actions.
Table 10-6 SwitchShow Output and Suggested Action
Output Suggested Action
Disabled Check the output from the switchShow command to determine whether or not the
switch is disabled. If the port is disabled (for example, due to persistent disable or
security reasons), attempt to resolve the issue and then enter the portEnable command.
Bypassed Check the output from the switchShow command to determine whether or not the port
is testing.
Loopback Check the output from the switchShow command to determine whether or not the port
is testing.
E_Port If the opposite side is not another switch, the link has come up in a wrong mode. Check
the output from the portLogShow or PortLogDump commands and identify the link
initialization stage where the initialization procedure went wrong.
F_Port If the opposite side of the link is a fabric device, the link has come up in a wrong mode.
Check the output from portLogShow or PortLogDump commands.
G_Port The port has not come up as an E_Port or F_Port. Check the output from portLogShow
or PortLogDump commands and identify the link initialization stage where the
initialization procedure went wrong.
L_Port If the opposite side is not a loop device, the link has come up in a wrong mode. Check
the output from portLogShow or PortLogDump commands and identify the link
initialization stage where the initialization procedure went wrong.
