The Value elements are updated with host names.

If the UPDATE operation fails, no visible feedback is provided to the user since that is an

asynchronous event. An error message is logged in the hpio-controller.log file with detailed

information.

Sample custom host names workflows

To help transition to a new host name generation strategy, two sample custom host name

implementations are available:

• A powershell based implementation which generates host names with an incremental digit

number (similar to the existing host name strategy)

Find this sample workflow in the following directory:

/Library/Hewlett-Packard/Infrastructure orchestration/Custom

Hostnames/samples/hostname powershell

• A sample that implements a pool of host names by storing predefined values in a database.

Whenever a server is created, a host name from the pool is consumed. The host name is

released for reuse when the associated server is removed, and it is updated in the case where

Matrix infrastructure orchestration detects an out-of-band host name change.

Find this sample workflow in the following directory:

/Library/Hewlett-Packard/Infrastructure orchestration/Custom

Hostnames/samples/hostname pool
