zipl - Prepare devices for stand-alone dump

zipl syntax

Parameters

-d <dump_device> or --dumpto=<dump_device>

is the device node of the DASD or SCSI partition, or tape device to be prepared as a dump device. zipl deletes all data on the partition or tape and installs the boot loader code there.

Note:

• If the dump device is an ECKD disk with fixed-block layout (ldl), a dump overwrites the dump utility. You must reinstall the dump utility before you can use the device for another dump.
• If the dump device is a tape, SCSI disk, FBA disk, or ECKD disk with the compatible disk layout (cdl), you do not need to reinstall the dump utility after every dump.

-M <dump_device_list>

contains the device nodes of the dump partitions, separated by one or more line feed characters. zipl writes a dump signature to each involved partition and installs the stand-alone multi-volume dump tool on each involved volume. Duplicate partitions are not allowed. A maximum of 32 partitions can be listed. The volumes must be formatted with cdl and use block size 4096.

<size>

(Optional) The amount of memory to be dumped. The value is a decimal number that can optionally be suffixed with K for kilobytes, M for megabytes, or G for gigabytes. The value is rounded to the next megabyte boundary.

If you limit the dump size below the amount of memory that is used by the system to be dumped, the resulting dump is incomplete. If no limit is provided, all of the available physical memory is dumped.

Note: For SCSI dump devices, the "size" option is not available.

-f or --force

ensures that no signature checking takes place when dumping. Any data on all involved partitions is overwritten without warning.

-n or --noninteractive

suppresses confirmation prompts that require operator responses to allow unattended processing (for example, for processing DASD or tape dump configuration sections). This option is available on the command line only.

-V or --verbose

provides more detailed command output.

--dry-run

simulates a zipl command. Use this option to test a configuration without overwriting data on your device.

During simulation, zipl performs all command processing and issues error messages where appropriate. Data is temporarily written to the target directory and is cleared up when the command simulation is completed.

-v or --version

displays version information.

-h or --help

displays help information.
