Hello. We have redundant SUP720s in SSO mode. We upgraded the IOS on both the active and standby SUPs. They independently boot the IOS with no problem.
I get this command when writing the configuration. "%PFREDUN-SP-4-BOOTSTRING_INVALID: The bootfile sup-bootflash:s72033-advipservicesk9_wan-mz.122-33.SXH2a.bin is present on the standby supervisor but not on the active"
Not sure why we get this when it is on both sup-bootflash and each can boot OK? Please advise.
