Troubleshooting Upgrade Problems
Standby PXM continually
reboots.
You can view the rebooting
process through the console
port.
— The active PXM card cannot bring up the standby card. The
following procedure assumes that this card has just been
installed in the switch and that you have given the standby card
sufficient time to synchronize with the Active card.
Interrupt the boot cycle by pressing Return. Timing is
important, so you might have to press Return multiple times.
When the pxm1ebkup or pxm45bkup prompt appears,
immediately enter the sysPxmRemove command to prevent the
Active card from rebooting the standby card while you are
working on it.
Enter the sysChangeEnet command and verify that the inet on
ethernet (e) and gateway inet (g) values are set to the boot and
gateway IP address set with the bootChange command on the
active card. Also, verify that the boot device is set to lnPci. The
sysChangeEnet command works like the bootChange
command, which is described in the “Setting the Boot IP
Address” section in Chapter 2, “Configuring General Switch
Features.”
Enter the sysClrallcnf command to clear any configuration
data on the standby card set. This command does not clear the
boot IP address set with the sysChangeEnet command.
After restart, the switch
stops at shell prompt:
pxm1e> or pxm45>.
— If the Return key is pressed at one of the auto-boot prompts
during start up, the switch stops in shell mode. Enter the reboot
2
1
command to restart the switch and avoid pressing the Return
key.
The non-active PXM will
not transition out of the
active init state.
One or more non-standby
PXM cards are in a
transitional state.
A non-standby PXM card is a standalone PXM card or the card
within a redundant PXM pair that is trying to go active. When
a non-standby PXM card is in a transitional state, such as the
init state, the PXM cannot transition to the standby state. When
all non-standby cards have reached a steady (non-transitional)
state, the PXM will transition to a steady state. Steady states are
as follows: active ready, failed, mismatch, empty, empty
reserved, and standby ready.
Note When either card in a redundant PXM pair is active, that
PXM pair is not preventing the standby PXM from
transitioning to a steady state. The standby PXM is only
affected when both cards in a redundant pair are in a
transitional state.
1. Beginning with Release 4.0, you must enter reboot 2. For all prior releases, enter reboot.
