Managing an appliance data disk
You can use apic
commands to manage appliance data disks in your VMware
deployment.
The API Connect deployment on VMware uses 2 partitions. The first contains the base operating system, while the second is encrypted so that any customer data that is stored on disk uses the encrypted volume. Encryption is done with Linux Unified Key Setup (LUKS) disk encryption.

when configuring the
host:apicup hosts create <SUBSYS> <HOSTNAME> <HD-PASSWD>
If you want to force a restart of processes, without requiring a full restart of the virtual
machine, you can use the command apic lock
to stop the Kubernetes node on the
virtual machine and lock the secured storage. When you are ready to restart processes, you can use
apic unlock
to restart the Kubernetes node. The command apic
unlock
uses the password to unlock the partition so that files can be read from it and
written to it. The unlock command also starts the apic
daemon, also known as the
appliance-manager
service.
You can check that status of this service with:
sudo systemctl status appliance-manager
One appliance-manager
daemon runs on each node, where it manages the Kubernetes
cluster, processes update and upgrade requests, and gathers logs.
