Example using options

Red Hat Enterprise Linux 9.2 LPAR mode z/VM guest KVM guest

You can partition a DASD by using the -a or -c option without entering the menu mode.

This method is useful for partitioning by using scripts, for example, if you need to partition several hundred DASDs.

With the -a option you can create one large partition on a DASD:

# fdasd -a /dev/dasdzzz
auto-creating one partition for the whole disk...
writing volume label...
writing VTOC...
rereading partition table...
#

This example creates a partition as follows:

         Device      start      end   length   Id  System
  /dev/dasdzzz1          2     1499     1498    1  Linux native

Using a configuration file that you can create several partitions. For example, the following configuration file, config, creates three partitions:

[first,500]
[501,1100]
[1101,last]

Submitting the command with the -c option creates the partitions:

# fdasd -c config /dev/dasdzzz
parsing config file 'config'...
writing volume label...
writing VTOC...
rereading partition table...
#

This example creates partitions as follows:

         Device      start      end   length   Id  System
  /dev/dasdzzz1          2      500      499    1  Linux native
  /dev/dasdzzz2        501     1100      600    2  Linux native
  /dev/dasdzzz3       1101     1499      399    3  Linux native
