How to Unconfigure All Multipathed FC Devices

An Ap_Id on a fabric-connected host port is a path to a multipathed device.

When a multipathed device has multiple Ap_Ids connected to it, the device is still available to the system after you unconfigure an Ap_Id. After you unconfigure the last Ap_Id, no additional paths remain and the device is unavailable to the system. Only devices on a fabric-connected host port can be unconfigured.

1. Become superuser.
2. Identify the devices to 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::220203708b9b20b2 disk       connected    configured   unknown
   c2                   fc-fabric  connected    configured   unknown
   c2::50020f2300005f24 disk       connected    configured   unknown

3. Unconfigure all of the configured devices on the selected port.

   # cfgadm -c unconfigure c2

   ---

   Note - This operation repeats the unconfigure command of an individual device for all devices on c2. This process can be time-consuming if the number of devices on c2 is large.

   ---

4. Verify that all devices on c2 are unconfigured.

   # cfgadm -al
   Ap_Id                Type       Receptacle   Occupant     Condition
   c0                   fc-fabric  connected   configured   unknown
   c0::50020f2300006077 disk       connected   configured   unknown
   c1                   fc-private connected   configured   unknown
   c1::220203708b69c32b disk       connected   configured   unknown
   c1::220203708ba7d832 disk       connected   configured   unknown
   c2                   fc-fabric  connected   unconfigured unknown
   c2::50020f2300005f24 disk       connected   unconfigured unknown
   c2::50020f2300006107 disk       connected   unconfigured unknown

   Notice that the Occupant column lists c2 and all the devices attached to c2 as unconfigured.
