x86: To Create a Disk Configuration File

1. Locate an x86 based system that contains a disk that you are testing.

2. Become superuser.

3. Create part of the single-disk configuration file by saving the output of the fdisk(1M) command in a file.

   # fdisk -R -W disk_config_file -h /dev/rdsk/device_name

   disk_config_file

   The name of a disk configuration file.

   /dev/rdsk/device_name

   The device name of the fdisk layout of the entire disk. device_name must be in the form cwtxdyp0 or cxdyp0.

4. Append the output of the prtvtoc(1M) command to the disk configuration file:

   # prtvtoc /dev/rdsk/device_name >>disk_config

   /dev/rdsk/device_name

   The device name of the system's disk. device_name must be in the form cwtxdys2 or cxdys2.

   disk_config

   The name of the disk configuration file

5. Determine if you are testing the installation of Solaris software on multiple disks.

   • If no, stop. You are finished.

   • If yes, concatenate the single–disk configuration files and save the output in a new file.

     # cat disk_file1 disk_file2 >multi_disk_config

     The new file becomes the multiple-disk configuration file, as in the following example.

     # cat 104_disk2 104_disk3 104_disk5 >multi_disk_test

6. Determine if the target numbers in the disk device names are unique in the multiple-disk configuration file that you created in the previous step.

   • If yes, stop. You are finished.

   • If no, open the file with a text editor and make the target numbers unique.

     For example, if the file contains the same target number, t0, for different disk device names as shown here:

     * /dev/rdsk/c0t0d0s2 partition map ... * /dev/rdsk/c0t0d0s2 partition map

     Change the second target number to t2, as shown here:

     * /dev/rdsk/c0t0d0s2 partition map ... * /dev/rdsk/c0t2d0s2 partition map
