When removing a device on AIX, you may run into a message saying that a child device is not in a correct state. For example:
# rmdev -dl fcs3
Method error (/usr/lib/methods/ucfgcommo):
0514-029 Cannot perform the requested function because a
child device of the specified device is not in a correct state.
To determine what the child devices are, use the -p option of the lsdev command. From the man page of the lsdev command:
-p Parent
Specifies the device logical name from the Customized Devices
object class for the parent of devices to be displayed. The
-p Parent flag can be used to show the child devices of the
given Parent. The Parent argument to the -p flag may contain
the same wildcard charcters that can be used with the odmget
command. This flag cannot be used with the -P flag.
For example:
# lsdev -p fcs3
fcnet3 Defined 07-01-01 Fibre Channel Network Protocol Device
fscsi3 Available 07-01-02 FC SCSI I/O Controller Protocol Device
To remove the device, and all child devices, use the -R option. From the man page for the rmdev command:
-R
Unconfigures the device and its children.
When used with the -d or -S flags, the
children are undefined or stopped, respectively.
The command to remove adapter fcs3 and all child devices, will be:
# rmdev -Rdl fcs3
