Migrating HDLM in a PowerHA 5.5 or PowerHA 6.1 Environment

When HDLM version 5.8.1 or earlier is migrated to HDLM version 5.9 or later,
the logical device file that can be controlled by the HDLM driver changes from
the HDLM device (dlmfdrvn) to hdisk. If the user application uses an LU
managed by HDLM, modify the user application appropriately.
In a virtual I/O server environment, you cannot migrate HDLM when you are
running PowerHA services.
The following procedure explains how to migrate HDLM in an PowerHA
environment. This procedure explains how to migrate HDLM when you are
using PowerHA 6.1. For details about how to use PowerHA, see the PowerHA
