Creating Disk Configuration Files

This section describes how to create single-disk and multiple-disk configuration files. Disk configuration files enable you to use pfinstall(1M) from a single system to test profiles against different disk configurations.

SPARC: How to Create a Single-Disk Configuration File

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

Example 4-9 SPARC: Creating a Disk Configuration File

The following example shows how to create a single–disk configuration file, 104_test, on a SPARC based system with a 104 MB disk.

Redirect the output of the prtvtoc command to a single-disk configuration file that is named 104_test:

# prtvtoc /dev/rdsk/c0t3d0s2 >104_test

The contents of the 104_test file resemble the following example:

* /dev/rdsk/c0t3d0s2 partition map
*
* Dimensions:
*     512 bytes/sector
*      72 sectors/track
*      14 tracks/cylinder
*    1008 sectors/cylinder
*    2038 cylinders*    2036 accessible cylinders
* Flags:
*   1: unmountable
*  10: read-only
*
*                          First     Sector    Last
* Partition  Tag  Flags    Sector     Count    Sector  Mount Directory
       1      2    00          0     164304   164303   /
       2      5    00          0    2052288  2052287  
       3      0    00     164304     823536   987839   /disk2/b298
       5      0    00     987840     614880  1602719   /install/298/sparc/work
       7      0    00    1602720     449568  2052287   /space

SPARC: How to Create a Multiple-Disk Configuration File

Locate a SPARC based system with a disk you want to test.
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.
Redirect 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.
Concatenate the single–disk configuration files and save the output in a new file.
```
# cat disk-file1 disk-file2 >multi-disk-config-file
```
The new file becomes the multiple-disk configuration file, as in the following example.
```
# cat 104_disk2 104_disk3 104_disk5 >multi_disk_test
```
If the target numbers in the disk device names are not unique in the multiple-disk configuration file, 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
```

x86: How to Create a Single-Disk Configuration File

Locate an x86 based system that contains a disk that you are testing.
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.
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 cwtxdys0 or cxdys0.
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.

Example 4-10 x86: Creating a Disk Configuration File

The following example shows how to create a single-disk configuration file, 500_test, on an x86 based system that contains a 500 MB disk.

First, save the output of the fdisk command to a file that is named 500_test:

# fdisk -R -W 500_test -h /dev/rdsk/c0t0d0p0

The 500_test file looks like the following:

 * /dev/rdsk/c0t0d0p0 default fdisk table
* Dimensions:
*     512 bytes/sector
*      94 sectors/track
*      15 tracks/cylinder
*    1455 cylinders
*
*  HBA Dimensions:
*     512 bytes/sector
*      94 sectors/track
*      15 tracks/cylinder
*    1455 cylinders
*
* systid:
*  1:    DOSOS12
*  2:    PCIXOS
*  4:    DOSOS16
*  5:    EXTDOS
*  6:    DOSBIG
*  86:   DOSDATA
*  98:   OTHEROS
*  99:   UNIXOS
* 130:   SUNIXOS
*
* Id  Act Bhead Bsect   Bcyl  Ehead  Esect  Ecyl Rsect  Numsect
 130  128 44    3       0     46    30     1001 1410   2050140

Append the output of the prtvtoc command to the 500_test file:

# prtvtoc /dev/rdsk/c0t0d0s2 >>500_test

The 500_test file is now a complete disk configuration file:

* /dev/rdsk/c0t0d0p0 default fdisk table    
* Dimensions:
*     512 bytes/sector
*      94 sectors/track
*      15 tracks/cylinder
*    1455 cylinders
*
*  HBA Dimensions:

x86: How to Create a Multiple-Disk Configuration File

Locate an x86 based system that contains a disk that you are testing.
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.
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 cwtxdys0 or cxdys0.
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.
Concatenate the single-disk configuration files and save the output in a new file.
```
# cat disk-file1 disk-file2 >multi-disk-config-file
```
The new file becomes the multiple-disk configuration file, as in the following example.
```
# cat 104_disk2 104_disk3 104_disk5 >multi_disk_test
```
If the target numbers in the disk device names are not unique in the multiple-disk configuration file, make the target numbers unique.
For example, the file might contain 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
```
