How to Unconfigure One Path to a Multipathed FC Device
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.
# 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
# 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.
# 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.
