This behavior sometimes causes trouble with old HBAs. Checking for a point-to-point initialization failure 1. Enter the switchShow command to confirm that the port is active and has a module that is synchronized. If a fabric device or another switch is connected to the switch, the switch port must be online. 2. Enter the portLogShow or portLogDump commands. 3.

Skip over the loop initialization phase. After becoming an active port, the port becomes an F_Port or an E_Port depending on the device on the opposite side. If the opposite device is a fabric device, the port becomes an F_Port. If the opposite device is another switch, the port becomes an E_Port. If there is a problem with the fabric device, enter the portCfgGPort to force the port to try to come up as point-to-point only. Correcting a port that has come up in the wrong mode 1.

Check the output from the portLogShow or PortLogDump commands and identify the link initialization stage where the initialization procedure went wrong. If the opposite side of the link is a private loop device or a switch, the link has come up in a wrong mode. Check the output from portLogShow or PortLogDump commands.

Received LISA frame
The
LISA frame
indicates that the loop initialization is complete.
3.
Skip point-to-point initialization by using the
portCfgLport
Command.
The switch changes to point-to-point initialization after the LISA phase of the loop initialization.
This behavior sometimes causes trouble with old HBAs.
Checking for a point-to-point initialization failure
1.
Enter the
switchShow
command to confirm that the port is active and has a module that is
synchronized.
If a fabric device or another switch is connected to the switch, the switch port must be online.
2.
Enter the
portLogShow
or
portLogDump
commands.
3.
Verify the event area for the port state entry is
pstate
. The command entry
AC
indicates that
the port has completed point-to-point initialization.

Skip over the loop initialization phase.
After becoming an active port, the port becomes an F_Port or an E_Port depending on the
device on the opposite side. If the opposite device is a fabric device, the port becomes an
F_Port. If the opposite device is another switch, the port becomes an E_Port.
If there is a problem with the fabric device, enter the
portCfgGPort
to force the port to try to
come up as point-to-point only.
Correcting a port that has come up in the wrong mode
1.
Enter the
switchShow
command.
2.
Check the output from the
switchShow
command and follow the suggested actions in
Table 4
.

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
or
portCfgPersistentEnable
command.
Bypassed
The port may be testing.
Loopback
The port may be 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 private loop device or a switch, the link has come up in a
wrong mode. Check the output from
portLogShow
or
PortLogDump
commands.
