Managing SAN Devices and I/O Multipathing in Oracle^® Solaris 11.4

How to Manually Configure an FC Device Without Multipathing

This sample procedure describes how to configure a fabric device that is attached to the fabric-connected host port c0.

1. Become an administrator.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

2. Identify the device to be configured.

   # 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
   c0::50020f2300005f24 disk      connected    unconfigured unknown
   c0::50020f2300006107 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

3. Configure the fabric device.

   # cfgadm -c configure c0::50020f2300006077

4. Verify that the selected fabric device is configured.

   # 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
   c0::50020f2300005f24 disk       connected   unconfigured unknown
   c0::50020f2300006107 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

   Notice that the Occupant column for both c0 and c0::50020f2300006077 displays as configured, indicating that the c0 port has a configured occupant and that the c0::50020f2300006077 device is configured.

5. Display FCP SCSI LUN information for multi-LUN SCSI devices.

   The following code example shows that the physical devices connected through Ap_Id c0:50020f2300006077 have four LUNs configured.

   # cfgadm -al -o show_SCSI_LUN c0
   Ap_Id                 Type       Receptacle   Occupant     Condition
   c0                  fc-fabric    connected    configured   unknown
   c0::50020f2300006077,0 disk      connected    configured   unknown
   c0::50020f2300006077,1 disk      connected    configured   unknown
   c0::50020f2300006077,2 disk      connected    configured   unknown
   c0::50020f2300006077,3 disk      connected    configured   unknown

   The device is now available on the system running the Oracle Solaris OS. The paths represent each SCSI LUN in the physical device represented by c0::50020f2300006077.
