Hi all, I have been trying to run updates on our 6506 VSS using the ISSU method. Everything went smoothly until running the issu loadversion command to boot the standby chassis to the new version. Now the standby is stuck in a bootloop, each time with the following errors:
*Feb 19 23:20:15.074: %PFREDUN-SW1_SP-4-PHYSMEM_MISMATCH: Asymmetrical redundant configuration: Active SP has (1048576/65536K) memory, Standby has (1048576/8192K).

The only way to get out of the bootloop is to wait for the rollback timer to kick in (hopefully, haven't waited that long yet) or manually reset the chassis.
As far as I know, the hardware of both chassis are identical.
We are trying to update from s72033-adventerprisek9_wan-mz.122-33.SXI3.bin to the modular variant of the same IOS version.
Same thing happened to me. I upgraded my VSS using ISSU eSFU with 12.2(33)SXI4 to 4a and encountered the same messages. As soon as issu loadversion was issued, the script kicked in and attempted to reload the standby. Except the standby never comes up and boots into Rommon mode. Then the Peer goes into Disabled state. I attempted to reboot the standby using various images but it always booted back into Rommon. This happened so many times that we began to suspect that the ISSU script had corrupted the sup and we had to RMA it. I should mention that my VSS is fully populated with service modules and was running modular SXI4.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
