Multipath Status Display
You can also use the "iompadm info" command to display the status of multiple paths for a device. The
"iompadm" command is installed in the /opt/FJSVmpd/bin directory. Only a root-level user may execute the
"iompadm" command.
3.4.1
"iompadm info" Command
Use the "iompadm info" command to display the status of multiple paths.
When a disk_device_node is specified, the path status for the specified storage system is displayed. A
disk_device_node represented by a special file (/dev/sdb, /dev/sdc, etc.) indicates the connection point
between a disk device and the storage system device.
The output of the command appears as follows:
path_status: "active", "standby", "stop", or "fail" is displayed.
status_details: "online", "warning", "stop by command", or an error message is displayed.
