[All Linux Operating Systems] After paths are lost and restored, it may be necessary to manually refresh device-mapper to update the host path state.
Because of a Linux defect, it may be necessary to run the following command to restore the path state after paths have been lost and restored on the host:
# /sbin/multipathd reconfigure
Running the /sbin/multipathd show maps topology command to show the state of the LUNs as seen by the kernel fails to show the current path status on the Linux host. This prevents the FSPM daemon from updating the LUN status.
Note: If you need to restart the multipath daemon on your operating system, review your operating system documentation before restarting the daemon.
If running the
multipathd reconfigure command does not recover the condition, run the following command to restart the multipath daemon:
# service multipathd restart
