This subcommand changes an active, standby, or warning status path to stop status and blocks the path.
This subcommand cannot change a fail or fatal fail status path to stop status. When executed with no
change_unit specified, the operation is performed as if "controller" was specified.
Refer to
"3.5 Disconnecting/Reconnecting Paths when Replacing Hardware" (page 51) for details of
change_unit.
When specifying an "adapter" as the change_unit, the following format is available.
This subcommand returns the status of a specified path to active/standby status and restarts path use.
When a fail or fatal fail status path becomes usable, this command may be used to change its status to
active/standby. To change a warning status path to active/standby, change its status to stop status using
the "iompadm change" command, and then use the "iompadm restart" command. When executed with no
change_unit specified, the operation is performed as if "controller" was specified.
Refer to
"3.5 Disconnecting/Reconnecting Paths when Replacing Hardware" (page 51) for details of
