Converting a Legacy Host Persona to a Host Persona
A legacy host persona is a host persona that simulates the behavior of a port persona. Prior to the
HP 3PAR InForm Operating System 2.3.1 release, port personas were used on system ports. Port
personas are no longer supported. If you upgraded to the current HP 3PAR InForm Operating
System release from version 2.3.1 or earlier, your port personas were converted to legacy host
personas during the upgrade process.
If you are converting from a legacy host persona with an operating system that supports RTPG,
you should convert to new persona number 2.
• To convert a legacy host persona is a host persona, issue the sethost -persona
<persona_num> <hostname> command, where:
◦ <persona_num> is the number of the new host persona.
◦ <host_name> is the name of the host with the legacy host persona to be converted to
the new host persona.
The sethost CLI command is described in detail in the HP 3PAR InForm OS Command Line
Interface Reference and the CLI Help Pages.
