Example: Using and Monitoring Hotfixes

This example presents several aspects of hotfix use. In this example, 6-0-1p0-5.rel is the currently armed and active release. Hotfix hf63035.hfx is compatible with this release and is currently activated and armed as a startup hotfix.

host1(config)# boot hotfix hf63037.hfx
% The hotfix, 34563037, requires the following hotfix(es) to be armed:
        23453036

The hf63036.hfx hotfix must be armed as a startup hotfix:

host1(config)# boot hotfix hf63036.hfx

This command succeeds because hf63036.hfx is compatible with the currently armed release, 6-1-0.rel, and has no dependencies on other hotfixes.

Now the attempt to arm hf63037.hfx succeeds because its dependency on hf63036.hfx has been met.

host1(config)# boot hotfix hf63037.hfx

Now suppose the user reloads the router:

host1# reload

As the router loads the armed release, 6-1-0.rel, the hotfix loader discovers three armed startup hotfixes, hf63035.hfx, hf63036.hfx, and hf63037.hfx. Only hf63036.hfx and hf63037.hfx are activated. Hotfix hf63035.hfx is disarmed because it is incompatible with the new running release. The router therefore becomes operational running 6-1-0.rel with hf63036.hfx and hf63037.hfx activated.

hf63036.hfx    X       X       
hf63037.hfx    X       X      23453036

Now suppose the user attempts to deactivate hf63036.hfx:

host1#no hotfix activate hf63036.hfx
The hotfix, 23453036, has the following active dependents which must be deactivated first:
        34563037
% De-activation failed.

The command fails because hf63037.hfx is dependent on hf63036.hfx. Interdependent hotfixes must be deactivated and disarmed in the reverse order that they were activated.

When 6-0-1p0-5.rel is re-armed and the router reloaded, the hotfix loader determines that the startup hotfixes, hf63036.hfx and hf63037.hfx, are incompatible with the release. It disarms these hotfixes. The user decides to delete the now unnecessary hotfixes from the router.

host1# delete hf63036.hfx
host1# delete hf63037.hfx
