HP Matrix Operating Environment 7.3 and 7.3 Update 1 Infrastructure Orchestration User Guide

Unregister a VM host
A Matrix infrastructure orchestration Administrator can use the IO CLI to unregister an unused VM
host. The following limitations apply:
• The host must not have any guests registered with Matrix infrastructure orchestration or Matrix
OE logical server management.
• The host must not have an associated Matrix OE logical server.
• The host must be in the service provider Unassigned pool.
You must specify the -C attribute to unregister a host in a cluster. An unclustered host can be
unregistered with or without the using the -C attribute.
An error message will appear if the VM host is in use and will prevent use of the host by IO while
the unregister operation is occurring. All hosts within a cluster will be automatically unregistered.

Interfaces API and CLI Operations Reference Guide available at http://www.hp.com/go/matrixoe/
docs.
Manual processes within the lifecycle operations
The execution of the infrastructure orchestration lifecycle operations might require the infrastructure
orchestration administrator to perform manual tasks. If defined, infrastructure orchestration invokes
an Operations Orchestration workflow to initiate, remind, or otherwise facilitate a manual task
and generates a Systems Insight Manager event. Use workflow integration or the infrastructure
orchestration console interface to signal completion of a manual task.
The manual tasks are associated with paused states in the infrastructure orchestration automation
and include:
• Boot disk allocation
When LUNs with the required attributes are not available for a Create Service or Add servers
to group operation, disk allocation is blocked and the infrastructure orchestration administrator
is notified.
The operation pauses until the infrastructure orchestration administrator:
◦ Works with a SAN administrator to create the storage.
◦ Defines the storage in HP Matrix OE logical server management.
◦ Continues the operation.
When the operation continues, infrastructure orchestration reattempts to allocate the resources.
Success depends on the availability of unused boot LUNs.
• Approval
After resources are reserved, the Create Service, Add servers to group, Add data disk to group,
and Change Lease Period (extend only) operations pause for infrastructure orchestration
administrator approval. The infrastructure orchestration administrator can approve or reject
the request. If the request is approved, the request continues into provisioning.
NOTE: Administrator submitted requests do not require approval.
• Manual operating system deployment
A service template typically assigns a server deployment or virtual machine software to a
group of servers, however it is possible (though not typical) to define a service template without
assigning server deployment or virtual machine software to a group of servers. In this case,
the Create Service and Add servers to group operations pause to allow the infrastructure
orchestration administrator to deploy the operating system manually.
