To Configure an Individual Device Without Multipathing

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

  1. Log in as root (su - root).
  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. Use the show_SCSI_LUN option to 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 host using the Solaris 10 OS. The paths represent each SCSI LUN in the physical device represented by c0::50020f2300006077.
