Configuration: About Your Host 91
• Changing a host type
MDSM automatically detects these changes for any host running the host
agent software.
Starting or Stopping the Host Context Agent
The host context agent discovers the host topology and starts and stops with
the host. The topology discovered by the host context 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.
Linux
To start or stop the host context agent, enter the following command at the
prompt:
SMagent start
SMagent stop
You stop and then restart SMagent after:
• Moving a controller offline or replacing a controller.
• Removing host-to-array connections from or attaching host-to-array
connections to a Linux host server.
