ml780b#rmdev -dl fcs0Method error usrlibmethodsucfgcommo 0514-029 Cannot perform the requested function because a child device of the specified device is not in a correct state

The error message indicates that the "rmdev" command failed to remove the device "fcs0" because one of its child devices is not in a correct state.

To resolve this issue, you can try the following steps:

1. Check the status of the child devices of "fcs0" using the "lsdev" command:

   # lsdev -Cc adapter | grep fcs0
   

   This will list all the child devices associated with "fcs0". Make a note of the child devices that are in an incorrect state.

2. Remove the child devices that are in an incorrect state using the "rmdev" command:

   # rmdev -dl <child_device>
   

   Replace "<child_device>" with the name of the child device that is in an incorrect state. Repeat this step for all the child devices that need to be removed.

3. Once all the child devices are removed, try removing the "fcs0" device again using the "rmdev" command:

   # rmdev -dl fcs0
   

   This should successfully remove the "fcs0" device.

If the issue persists or you encounter any other errors, it is recommended to consult the documentation or seek assistance from the system administrator or technical support.
