Installing/reinstalling the sg and the st drivers

You must install the NetBackup sg driver and the Sun st driver on each Solaris NetBackup media server that hosts tape devices.

Each time you add or remove a device, you should configure the NetBackup sg driver and the Sun st driver again. For 6 GB and larger serial-attached SCSI (SAS) HBAs, also configure class 08 and 0101 for the sg driver.

See Configuring 6 GB and larger SAS HBAs in Solaris.

Before you configure the sg and the st drivers, ensure that all devices are turned on and connected to the HBA.

The sg.build command uses the Solaris sasinfo command to probe for SAS attached device paths. This command is only available on Solaris 11 and later. On Solaris 10 and earlier, you must configure the sg driver manually.

To install and configure the sg and the st drivers

  1. Invoke the following two commands to run the NetBackup sg.build script:
    cd /usr/openv/volmgr/bin/driver
/usr/openv/volmgr/bin/sg.build all -mt target -ml lun

    The following describes the options:

    • The all option creates the following files and populates them with the appropriate entries:

      • /usr/openv/volmgr/bin/driver/st.conf

      • /usr/openv/volmgr/bin/driver/sg.conf

      • /usr/openv/volmgr/bin/driver/sg.links

    • The -mt target option and argument specify the maximum target ID that is in use on the SCSI bus (or bound to an FCP HBA). The maximum value is 126. By default, the SCSI initiator target ID of the adapter is 7, so the script does not create entries for target ID 7.

    • The -ml lun option and argument specify the maximum number of LUNs that are in use on the SCSI bus (or by an FCP HBA). The maximum value is 255.

  2. Replace the following seven entries in the /kernel/drv/st.conf file with all of the entries from the /usr/openv/volmgr/bin/driver/st.conf file:
    name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=1 lun=0;
name="st" class="scsi" target=2 lun=0;
name="st" class="scsi" target=3 lun=0;
name="st" class="scsi" target=4 lun=0;
name="st" class="scsi" target=5 lun=0;
name="st" class="scsi" target=6 lun=0;

    You should make a backup copy of the /kernel/drv/st.conf file before you modify it.

  3. Reboot the system with the reconfigure option (boot -r or reboot -- -r).

    During the boot process, the system probes all targets in the st.conf file for devices. It should create device files for all of the devices it discovers.

  4. Verify that Solaris created the device nodes for all the tape devices by using the following command:

    ls -l /dev/rmt/*cbn

  5. Install the new sg driver configuration by invoking the following two commands:
    /usr/bin/rm -f /kernel/drv/sg.conf
/usr/openv/volmgr/bin/driver/sg.install

    The NetBackup sg.install script does the following:

    • Installs and loads the sg driver.

    • Copies the /usr/openv/volmgr/bin/driver/sg.conf file to /kernel/drv/sg.conf.

    • Creates the /dev/sg directory and nodes.

    • Appends the /usr/openv/volmgr/bin/driver/sg.links file to the /etc/devlink.tab file.

  6. Verify that the <command>sg</command> driver finds all of the robots and tape drives.
