Cisco 7613 Router boots from sup-bootdisk instead of disk0 as per boot system command
I have a C7613 with two sup engines in redundant mode (SSO).
My issue is as follows;
I have IOS 12.2.18 in sup-bootdisk and IOS 12.2.33 in disk0 in both SUP720s. I have set the boot variable as "boot system flash disk0:"
The issue is that SUP1 loads with .33 IOS and SUP2 loads with .18 IOS. For some reason SUP2 does not follow the boot system command.
In some cases, SUP2 correctly loads from disk0 using .33 IOS in other cases it loads .18 IOS.
I have another 7613 at a different site with the same setup and IOS and it boots correctly all the time.
The main difference is that I got a replacement SUP for the SUP2 for the router with the above issue and since then I have had the issue. The replacement SUP is identical to the existing SUP (memory,flash,MSFC,etc).
Is there some setting maybe i need to configure for the replacement SUP?

I know you wrote that you have identical Sup replacement, but can you make sure that the PFC for both Sups are exactly the same?
We had an issue like this before. Cisco have sent us PFC-3CXL instead of 3C and it took us a while to figure it out and send back the 3CXL to get a replaced with a 3C. Also if they are both 3C check the version number and make sure the new one is the same as the old one you aready have.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
