6500 Switch Reloads to ROMMON Prompt

Hello,

I have a 6509 switch that once rebooted goes to the rommon prompt and requires me to intervene in order to get the switch to boot.

As far as I can see the boot command is OK and the boot variable points towards a file that exists in the bootflash. Below are some excerpts from the config and the console as the switch is reloaded. If anyone has any ideas as to what is missing I would appreciate it.

I am trying to boot using the IOS file: s72033-ipservicesk9_wan-mz.122-33.SXJ6.bin

The file is located on the internal sup-bootdisk

The supervisor is a SUP720-3B

Regards

A

6500 Switch Reloads to ROMMON Prompt

It may be your configuration register that is the problem. If you do -

1) "sh bootvar"  this will show the configuration register on the RP. It will probably be 0x2102

2) "remote command switch show bootvar" this will show the configuration register on SP.

If 2) is not showing 0x2102 then do -

switch(config)# config-register 0x2102

then repeat 1) and 2) again to check they are both the same. No need to save config as the configuration register is not part of the running config.
