Recovering from dead EMC paths
If you run:
# powermt display dev=allAnd you notice that there are "dead" paths, then these are the commands to run in order to set these paths back to "alive" again, of course, AFTER ensuring that any SAN related issues are resolved.
To have PowerPath scan all devices and mark any dead devices as alive, if it finds that a device is in fact capable of doing I/O commands, run:
# powermt restoreTo delete any dead paths, and to reconfigure them again:
# powermt resetOr you could run:
# powermt config
# powermt check
