SPARC: How to Create a Multiple Disk Configuration File for a SPARC System

If you need to test a profile on multiple disks, you can concatenate disk configuration files together to create multiple disk configuration scenarios.

Overview - The procedure to create a multiple disk configuration file for a SPARC workstation involves:

• Concatenating two or more disk configuration files into one file

• Changing the target numbers of the disks (if needed)

  The following procedure creates a disk configuration file to test a profile on two 104-Mbyte disks:

1. Concatenate the 104_test file with itself and save the output to another file:

   $ cat 104_test 104_test > dual_104_test

2. Edit the disk configuration file so that each disk device name has a different target number.

   For example, the dual_104_test file is shown as follows:

   # cat dual_104_test * /dev/rdsk/c0t3d0s2 partition map * * Dimensions: * 512 bytes/sector * 35 sectors/track * 6 tracks/cylinder * 210 sectors/cylinder * 1019 cylinders * 974 accessible cylinders * * Flags: * 1: unmountable * 10: read-only * * First Sector Last * Partition Tag Flags Sector Count Sector Mount Directory 0 2 00 0 16170 16169 1 3 00 16170 28140 44309 2 5 00 0 204540 204539 6 4 01 44310 160230 204539 * /dev/rdsk/c0t0d0s2 partition map * * Dimensions: * 512 bytes/sector * 35 sectors/track * 6 tracks/cylinder * 210 sectors/cylinder * 1019 cylinders * 974 accessible cylinders * * Flags: * 1: unmountable * 10: read-only * * First Sector Last * Partition Tag Flags Sector Count Sector Mount Directory 0 2 00 0 16170 16169 1 3 00 16170 28140 44309 2 5 00 0 204540 204539 6 4 01 44310 160230 204539

   Because dual_104_test file was created by concatenating itself, the following editing was required:

   • The first disk device name was left as is.

   • The second disk device name was changed from /dev/rdsk/c0t3d0s2 to /dev/rdsk/c0t0d0s2 so it has a unique target number.

   You have completed creating a multiple disk configuration file.
