How to Unconfigure All FC Devices on a FC Host Port

This procedure describes how to unconfigure all configured fabric devices that are attached to a fabric-connected host port.

1. Become superuser.
2. Identify the fabric devices to be unconfigured.

   Only devices on a fabric-connected host port can be unconfigured.

   # cfgadm -al
   Ap_Id                Type         Receptacle   Occupant     Condition
   c0                 fc-fabric   connected    configured   unknown
   c0::50020f2300006077 disk      connected    configured   unknown
   c0::50020f23000063a9 disk      connected    configured   unknown
   c1                 fc-private  connected    configured   unknown
   c1::220203708b69c32b disk      connected    configured   unknown
   c1::220203708ba7d832 disk      connected    configured   unknown

3. Stop all activity to each fabric device on the selected port and unmount any file systems on each fabric device.

   If the device is under any volume manager’s control, see your volume manager documentation before unconfiguring the device.

   # cfgadm -c unconfigure c0

4. Unconfigure all of the configured fabric devices on a selected port.

   Note - This operation repeats the unconfigure operation of an individual device for all the devices on c0. This process can be time-consuming if the number of devices on c0 is large.

5. Verify that all the devices on c0 are unconfigured.

   # cfgadm -al
   Ap_Id                Type         Receptacle   Occupant     Condition
   c0                   fc-fabric    connected    unconfigured unknown
   c0::50020f2300006077 disk         connected    unconfigured unknown
   c0::50020f23000063a9 disk         connected    unconfigured unknown
   c1                   fc-private   connected    configured   unknown
   c1::220203708b69c32b disk         connected    configured   unknown
   c1::220203708ba7d832 disk         connected    configured   unknown

   Notice that the Occupant column of c0 and all the fabric devices attached to it are displayed as unconfigured.
