Cisco COS upgrade problem

During an upgrade of a COS the standby sup engine is not coming up.

The active Sup comes up as expected. How can I get the the secondary to sync? During boot on the active it says "Module 2 is found but not in standby"

When I go to the console on the secondary it is romon. We had to delete the

old file from flash so when you do a dir bootflash: it shows the old file. Any help would be appreciated.

If the Sup lets you to boot from, boot it from the old image. What kind of switch is it? Does it have a PCMCIA slot? If it does, and you have a flash card, try booting from flash card using the same version as in active Sup

Thank you for your reply. Off the top off your head what do you know the syntax to copy tftp -> slot0? Once I get the new version on the switch will the switch automatically sync?

Since you already have one Supervisor up, you must be having a valid file in the device bootflash. Port it to the flash card using "copy bootflash: slot0:"


Switch> (enable) copy bootflash:cat6000-sup2.6-3-10.bin slot0:

18889712 bytes available on device slot0, proceed (y/n) [n]? y


File has been copied successfully.

Using this flash card, boot the other supervisor which is in rommon

rommon1>boot slot0:cat6000-sup2.6-3-10.bin
