Yes you need to archive const_nvram:vlan.dat too.
This is one of my peeves with IOS on the 6500. We run
RPR+ so use global config mode rather than VLAN database
mode for configuration, it's annoying to see the commands
not end up in the config where they can be seen, and easily
archived.
What's the config register before you change it ?
Maybe you have bad NVRAM.

Subject: [nsp] 6509 going to rommon
Hello List,
Have a 6509 sup2/msfc2 running native IOS 12.1(8a)EX.
It has single AC power supply and couple of gigE
ports. I have two recent occurences of the router
going to rommon mode. Upon inspection power management
on the sup module goes to red and active light is off.
Yes, the 6509 is on a UPS.
The router is not sending any logs to a logging server
so cant examine the logs (will set this up).
Reloading on the rommon prompt goes back to rommon
mode. I have to execute config-register 0x2102 and
then boot to make it boot properly.
Unfortunately, upon normal booting, configs are lost.
What i do is copy the backup config from the tftp
server. Is the config still on nvram when booting from
rommon?
Im just backing up startup-config, which file on nvram
do you backup to have a copy on the vlan database ? I
have to manually re-enter the vlans. Since the 6509 is
the vtp server, how do you manually increase the
config revision number?
What could cause the 6509 to go to rommon mode?
Thanks.
