2.3.1 Connecting to Solaris Systems

The following procedure explains how to connect the disk devices to a Solaris system.

1. Connecting the SCSI/FC-SCSI Card

   Connect the SCSI card or Fibre Channel card to the server.

2. Connecting the SCSI/FC Cable

   Connect the SCSI card or Fibre Channel, which has just been connected to the server, to the disk array device (Fibre Channel switch/hub) with a cable.

3. Installing the SCSI/FC Driver

   Follow the instructions in the installation guide that came with the SCSI card or Fibre Channel card and install the SCSI/FC driver.

4. Setting the Fabric Environment

   Information must be added to the system configuration file in the fabric environment. For more details on this setup, refer to the instructions that came with the Fibre Channel card or Fibre Channel switch.

5. Setting the LUN

   In order to use a disk array with multiple LUNs, the "/kernel/drv/sd.conf" file must be edited.
   Normally in Solaris, the file is configured for using LUN0 only.
   The following example adds LUN1 to 7 for Target-ID=0.

   

   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=0;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=1;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=2;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=3;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=4;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=5;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=6;
   name="sd" class="scsi" class_prop="atapi"
           target=0 lun=7;
   
   name="sd" class="scsi" class_prop="atapi"
           target=1 lun=0;
   
   name="sd" class="scsi" class_prop="atapi"
           target=2 lun=0;
   
   name="sd" class="scsi" class_prop="atapi"
           target=3 lun=0;

   
   

6. Rebooting the system

   Reboot the system to enable the settings relating to the connection of the disk array device.

   # shutdown -y -g0 -i0  : shuts down the system.
   # boot -r              : "-r" reboots the system.

   There are precautions to take when rebooting the system of systems with Fibre Channel switches. For more details, refer to the manual for the Fibre Channel switch.

7. Checking the LUN and SCSI target ID

   Execute the format command to check whether or not the new LUN and Target ID settings are reflected properly. The following is an example of the format command being executed.

   

   # format

   Specify disk (enter its number):

   Specify the disk number used as the data transfer volume. The following is an example using the "c4t0d0" disk.

   

   Specify disk (enter its number):3    "3" represents "c3t0d0"
   selecting c3t0d0                     This message is displayed when c3t0d0 is selected.
   [disk unformatted]                   This message is displayed if the disk is not formatted yet.
                                        There is no display if the disk is formatted.
   Disk not labeled.  Label it now?     This display asks if you want to label the disk.
                                        Enter "y" to execute disk labeling.

This completes the connection of the disk array device.

Do not create a file system on the disk used as the data transfer volume.
