SPARC: To Create a Disk Configuration File

1. Locate a SPARC based system with a disk you want to test.

2. Become superuser or assume an equivalent role.

   Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

3. Create a single–disk configuration file by redirecting the output of the prtvtoc(1M) command to a file.

   # prtvtoc /dev/rdsk/device_name >disk_config_file

   /dev/rdsk/device_name

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

   disk_config_file

   The name of the disk configuration file.

4. 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

5. 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 in the disk device names.

     For example, assume that 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
