After an upgrade ends in errors, the device may be left in a state that it erroneously believes to still be in the middle of the upgrade.
Secondary blade blocks all ASM traffic.
A second blade is installed into a chassis and there are errors as it comes up. System configuration is never successfully loaded. This can occur during upgrades to versions prior to 12.0.0.
1) Delete the /var/ts/var/install/ucs_install.pid file on all blades 2) Push a fresh sync from a good device.
The system correctly detects that it is no longer in the middle of an upgrade.
