HP E4510-48G Command Reference Manual page 1280

cluster-name: Name of an existing cluster, a string of 1 to 8 characters, which can only be letters,
numbers, subtraction sign (-), and underline (_).
Description
Use the administrator-address command to add a candidate device to a cluster.
Use the undo administrator-address command to remove a member device from the cluster.
By default, a device belongs to no cluster.
Note that:
The administrator-address command is applicable on candidate devices only, while the undo
administrator-address command is applicable on member devices only.
You are recommended to use the delete-member command on the management device to
remove a cluster member from a cluster.
Examples
# Remove a member device from the cluster.
<aabbcc_1.Sysname> system-view
[aabbcc_1.Sysname] cluster
[aabbcc_1.Sysname-cluster] undo administrator-address

Default Level
2: System level
Parameters
recover: Automatically reestablishes communication with all the member devices.
Description
Use the auto-build command to establish a cluster automatically.
Note that:
This command can be executed on a candidate device or the management device.
If you execute this command on a candidate device, you will be required to enter the cluster name
to build a cluster. Then the system will collect candidates and add the collected candidates into
the cluster automatically.
If you execute this command on the management device, the system will collect candidates
directly and add them into the cluster automatically.
The recover keyword is used to recover a cluster. Using the auto-build recover command, you
can find the members that are currently not in the member list and add them to the cluster again.
