How to set boot variable for standby Sup2 in 6500?

I'm upgrading a 6500 with dual Sup2. Have copied the new boot image and system image to both bootflash and slavebootflash. Have also set new boot statements for the active Sup.

However couldn't set the boot variables for the standby Sup. Do I need to? Will the boot statements in the startup config take care both Sup's?

Thanks

Gary

If you do a wr mem, it should synchronize. You can verify using sh bootvar. Here is outputs from my lab

Router#sh bootvar

BOOT variable = sup-bootflash:c6sup22-jsv-mz.121-26.E3,1

CONFIG_FILE variable =

BOOTLDR variable =

Configuration register is 0x2102

Standby is up

Standby has 227328K/34816K bytes of memory.

Standby BOOT variable = sup-bootflash:c6sup22-jsv-mz.121-26.E3,1

Standby CONFIG_FILE variable =

Standby BOOTLDR variable =

Standby Configuration register is 0x2102

I have copied running config to startup, but when I did sh bootvar, I could only see the firt half of your output till "....0x2102", but not the 2nd half where it showed the standby information.

Any suggestion? Thanks

Please check wheter the sup's are really synchronized. The following URL contains a lot of info on the subject:
