Emergency field hot patch

In the event of an emergency, when an in-field fix is needed, SoftIron can provide an emergency hot patch that can be added to the cluster. This is an extreme circumstance when a fix CANNOT wait for a new HyperCloud release.

To apply such a fix from SoftIron, perform something similar to the process below:

# Copy patch file to cluster then to 10.0.1.10 (floating services static node)
ssh 10.0.1.10
HOTPATCH_ADD_NO_SIGNATURES=1 hotpatch-add <patch>
