To mount an HDLM-managed device automatically by setting a new HDLM device:

  1. Identify the name of the logical device file of the HDLM device to be mounted automatically.

    Execute the view operation of the HDLM command, and identify the applicable name of the logical device file of the HDLM and SCSI devices. For details on the view operation, see COM_MNL_VIEW_(DISPLAYS_INFORMATION)=GUID-311C4B1B-E8E6-4963-9C3C-6D33AD0261DD=3=EN=.html. The following is an actual example.

    Example of executing the dlnkmgr command's view operation (with -drv specified):

    # /opt/DynamicLinkManager/bin/dlnkmgr view -drv
    PathID HDevName Device LDEV
    000000 sddlmaa /dev/sdh VSP_Gx00.410025.00280B
    000001 sddlmab /dev/sdi VSP_Gx00.410025.00280C
    000002 sddlmac /dev/sdj VSP_Gx00.410025.00280D
    000003 sddlmaa /dev/sdk VSP_Gx00.410025.00280B
    000004 sddlmab /dev/sdl VSP_Gx00.410025.00280C
    000005 sddlmac /dev/sdm VSP_Gx00.410025.00280D
    000006 sddlmaa /dev/sdn VSP_Gx00.410025.00280B
    000007 sddlmab /dev/sdo VSP_Gx00.410025.00280C
    000008 sddlmac /dev/sdp VSP_Gx00.410025.00280D
    000009 sddlmaa /dev/sdq VSP_Gx00.410025.00280B
    000010 sddlmab /dev/sdr VSP_Gx00.410025.00280C
    000011 sddlmac /dev/sds VSP_Gx00.410025.00280D
    KAPL01001-I The HDLM command completed normally. Operation name = view(-vstv), completion time = yyyy/mm/dd hh:mm:ss
    #

    In the example, the name of the logical device file of the HDLM device that corresponds to /dev/sdh can be identified as sddlmaa.

  2. Add the name of the logical device file of the HDLM device that was confirmed in step 1 to the /etc/fstab file.

    The following is an example of editing the /etc/fstab file:

    • For FC-SAN environments

      /dev/sddlmaa     /mnt/sdh        ext2    defaults       0 0
    • For IP-SAN environments

      • If the OS is Red Hat Enterprise Linux 7:

        /dev/sddlmaa     /mnt/sdh        ext2    _netdev        0 0
      • If the OS is SUSE LINUX Enterprise Server 12 or 15:

        /dev/sddlmaa     /mnt/sdh        ext2    nofail        0 0
    • For QLogic 8400 Series (FCoE) environments

      • If the OS is Red Hat Enterprise Linux 7:

        /dev/sddlmaa     /mnt/sdh        ext2    _netdev        0 0

    This example adds a line for /dev/sddlmaa (name of the logical device file of the HDLM device). For IP-SAN environments, specify _netdev or nofail for the mount option.In addition, for QLogic 8400 Series (FCoE) environments, specify _netdev for the mount option.

  3. Restart the host or manually mount the HDLM device.

    HDLM-managed devices are mounted by using the logical device file name of the HDLM device.
