• Changing a host type
MDSM automatically detects these changes for any host running the host
agent software.
Starting or Stopping the Host Context Agent

agent can be viewed by clicking Configure Host Access (Automatic) in the
Configure tab in the MDSM.
You must stop and restart the host context agent to see the changes to the
host topology if:
• A new storage array is attached to the host server.
• A host is added while turning on power to the RAID controller modules.

connections to a Linux host server.
