To Unconfigure a Fabric Device Associated With Sun StorageTek Traffic Manager Multipathing-Enabled Devices

This procedure shows fabric-connected host ports c0 and c2 to illustrate how to unconfigure fabric devices associated with Sun StorageTek Traffic Manager software devices.

1. Log in as root (su - root)..

2. Identify the port WWN of the fabric device 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::220203708ba7d832 disk connected configured unknown c2 fc-fabric connected configured unknown c2::50020f2300005f24 disk connected configured unknown c2::50020f2300006107 disk connected configured unknown

   In this example, the c0::50020f2300006077 and c2::50020f2300006107 Ap_Ids represent different port WWNs for the same device associated with a Sun StorageTek Traffic Manager software device. The c0 and c2 host ports are enabled for use by the Sun StorageTek Traffic Manager software.

3. Stop all device 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 the documentation for your volume manager for maintaining the fabric device.

4. Unconfigure fabric devices associated with the device.

   Only devices on a fabric-connected host port can be unconfigured through the cfgadm -c unconfigure command.

   # cfgadm -c unconfigure c0::50020f2300006077 c2::50020f2300006107

   ---

   Note –

   You can remove a device from up to eight paths individually, as in the example command cfgadm -c unconfigure c0::1111, c1::2222, c3::3333, and so on. As an alternative, you can remove an entire set of paths from the host, as in the example cfgadm -c unconfigure c0.

5. Verify that the selected devices are unconfigured.

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

   Notice that the Ap_Ids c0::50020f2300006077 and c2::50020f2300006107 are unconfigured. The Occupant column of c0 and c2 still displays those ports as configured because they have other configured occupants.

   The Sun StorageTek Traffic Manager software devices associated with the Ap_Ids c0::50020f2300006077 and c2::50020f2300006107 are no longer available to the host using the Solaris Express Developer's Edition OS. The following two devices are removed from the host:

   /dev/rdsk/c6t60020F20000061073AC8B52D000B74A3d0s2

   /dev/rdsk/c6t60020F20000061073AC8B4C50004ED3Ad0s2
