Host agent uninstallation errors
You are not able to
reload the Emulex driver
for the Linux host after
installing the host agent.
When the host agent is running on Linux, it keeps contact with the HBA driver. You may receive a
lpfcdd: Device or resource busy message when trying to rmmod the driver. Try to stop
the host agent and then reload the HBA driver.
To stop the host agent for UNIX hosts:
/opt/sanmgr/hostagent/sbin/HA_trigger stop
/opt/sanmgr/hostagent/sbin/dial_trigger stop
To start the host agent for UNIX hosts:
/opt/sanmgr/hostagent/sbin/HA_trigger start
/opt/sanmgr/hostagent/sbin/dial_trigger start
A partial installation may have occurred due to a network timeout or other similar reason. Instead of
reinstalling the software, you may need to remove any partial host agent components on the host
first and then retry the installation.
Installing the host agent
has failed and reinstalling
the host agent software
does not solve the
problem.
If you used the local installation method, run the uninstall script that comes with the local installation
package. If you used the remote deployment tool, use the tool to uninstall the partially installed
components.
