Troubleshooting Upgrade Problems
After restart, switch stops at
backup boot prompt:
pxm45bkup>.
(Use a console port
connection to see this. If you
missed the startup messages,
enter the reboot command.)
The switch displays the
message: Can not open file
C:/version.
The version file is probably missing. Create the version file as
described in the “Initializing the Switch” section in Chapter 2,
“Configuring General Switch Features.”
The switch displays the
message: Unable to
determine size of
C:/FW/filename.
The version recorded in the version file doesn’t match software
installed in the C:FW directory.
Enter the sysVersionShow command to see which file the
PXM45 is trying to load.
Verify that the correct software is installed on the switch using
the commands described inthe “Browsing the File System in
Backup Boot Mode” section in Appendix B, “PXM45 Backup
Boot Procedures.”
If the runtime software is not on the hard disk, copy it to the
hard disk as described in the “Transferring Software Files to
and from the Switch” section in Appendix B, “PXM45 Backup
Boot Procedures.”
If a typo is entered when initializing the switch, re-enter the
sysVersionSet command, enter the sysVersionShow command
to verify the correct setting, and then reboot the switch with the
reboot command.
The switch displays the
message: Please run
sysDiskCfgCreate.
The hard disk is formatted, but not ready for operation. Enter
the sysDiskCfgCreate command. For more information, see
the “Initializing the PXM45 Hard Disk” in Appendix B,
“PXM45 Backup Boot Procedures.”
Standby PXM45 continually
reboots.
You can view the rebooting
process through the console
port.
The active PXM45 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 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.
