Got a 6500 with dual 720. currently the secondary sup shows a cold state. i know this means that two sups are running different IOS images.
when i check the file system the primary boots off of the sup-bootdisk:, but on the secondary there is no slavesup-bootdisk:, just slavedisk1:
question is do both of the sup's have to have the ios image located on the same storage device.

No, they boot from seperate storage devices. If your primary sup fails, then your secondary would not have access to the flash of the failed sup.
I don't have a 6500 with redundant sups (mine are VSS), but my 4510R's show a slavebootflash:
Where is the current ios stored that the slave is pointed to? Is it on slavedisk1?

Hello Eddie,
there shouldn't be this requirement it should be enough for them to run the same image name and version.
this information is carried in packets exchanged in the redundancy protocol between the two supervisors.
Hope to help

Eddie,
Try using sup-bootflash: for your bootstrings. You will want to have your IOS stored on the same location on BOTH supervisors (such as disk0: or sup-bootflash:).
HTH,
Mark
