This sample procedure uses fabric-connected host ports c0 and c2 to configure fabric devices as multipathed devices on a system that has the multipathing software enabled.
The cfgadm -c configure command for fabric devices is the same regardless of whether multipathing is enabled.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.
Look for devices on a fabric-connected host port marked as fc-fabric. These devices are the devices you can configure with the cfgadm -c configure command.
# 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 c1::220203708b8d45f2 disk connected configured unknown c1::220203708b9b20b2 disk connected configured unknown c2 fc-fabric connected unconfigured unknown c2::50020f2300005f24 disk connected unconfigured unknown c2::50020f2300006107 disk connected unconfigured unknown
In the above example, the c0::50020f2300006077 and c2::50020f2300006107 Ap_Ids represent the same storage device with different port WWNs for the storage device controllers. The c0 and c2 host ports are enabled for multipathing.
# cfgadm -c configure c0::50020f2300006077 c2::50020f2300006107
# cfgadm -al Ap_Id Type Receptacle Occupant Condition c0 fc-fabric connected configured unknown c0::50020f2300006077 disk connected configured 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 c1::220203708b8d45f2 disk connected configured unknown c1::220203708b9b20b2 disk connected configured unknown c2 fc-fabric connected configured unknown c2::50020f2300005f24 disk connected unconfigured unknown c2::50020f2300006107 disk connected configured unknown
Notice that the Occupant column of c0 and c0::50020f2300006077 specifies configured, which indicates that the c0 port has at least one configured occupant and that the c0::50020f2300006077 device is configured. The same change has been made in c2 and c2::50020f2300006107.
When the configure operation has been completed without an error, multipathed devices are created on the system. If the physical device represented by c0::50020f2300006077 and c2::50020f2300006107 has multiple SCSI LUNs configured, each LUN is configured as a multipathed device. The example below shows that two LUNs are configured through c0::50020f2300006077 and c2::50020f2300006107. Each Ap_Id is associated with a path to multipathed devices.
# cfgadm -al -o show_SCSI_LUN c0::50020f2300006077\ c2::50020f2300006107 Ap_Id Type Receptacle Occupant Condition c0::50020f2300006077,0 disk connected configured unknown c0::50020f2300006077,1 disk connected configured unknown c2::50020f2300006107,0 disk connected configured unknown c2::50020f2300006107,1 disk connected configured unknown
The example above shows that the following two multipathed devices are created for the device represented by c0::50020f2300006077 and c2::50020f2300006107:.
