When running the multipath command several devices report failed paths. After Checking confirmed that the underlying storage devices were all online and available but the device mapper multipath layer did not automatically re-enable the paths. Although a full server reboot would recover access to all paths a non-disruptive manual procedure was preferred that could be performed online.

Supprimer un path

echo 1 > /sys/block/sdcu/device/delete

Puis rescan pour remonter le path
