Document Title
Initialize Disk Drives so All Data is Erased Off of a System

Document Description
In some cases, a customer may wish to erase all data off their system. They may want to do this because they are discontinuing the system and want to destroy or remove all data on the system.

If this is to remove the data from a system upon completion of a Disaster Recovery test and the test was done on a secondary partition, follow the steps as outlined in the section No Partitions on the partition that was used for the test to erase the data from that partition. It is not necessary to run this procedure on any other partition other than the one where the test was performed.

No Partitions:

The procedure for doing this follows:
1.Do a D Manual IPL using a SAVSYS, full system save, or LIC Install CD.
2.The first menu will give an Option 1 to Install LIC, and Option 2 to use DST. Select Option 1.
3.The Install LIC menu will provide 5 options. Select Option 2 to Install Licensed Internal Code and Initialize System.

Note: Data still remains on the disk units until the following steps are completed.
4.After the installation of LIC is complete, the system will IPL to the DST primary menu (IPL or Install the System).
5.Configure all the disk drives by adding them into system ASP (ASP 1). This writes zeroes on the disk drives so only the LIC is loaded.

a Select Option 3 - Use DST.
b Work with Disk Units.
c Work with Disk Configuration.
d Work with ASP Configuration.
e Add units to ASPs.
f Type 1 in front of all the available units.

Note: If using the LIC Install CD (I_Base) to install LIC, the default password for QSECOFR will be uppercase QSECOFR.
6.When that is complete, power off the system by pressing the power button two times.
The system is clean and ready to go.

Partitioned System: (If this is a legacy system with a primary partition, this will remove all partitions and erase all data on drives from all earlier partitions.)

Note: This is true only for legacy systems that use a Primary partition. On HMC partitions the procedure must be done to each partition because they are independent of each other. Steps 5, 6 and 7 below do not pertain to HMC managed partitions.

The procedure for doing this follows:

1.Do a D Manual IPL using a SAVSYS, full system save, or LIC Install CD of the primary partition.
2.The first menu will give an Option 1 to Install LIC, and Option 2 to use DST. Select Option 1.
3.The Install LIC menu will provide 5 options. Select Option 2 to Install Licensed Internal Code and Initialize System.
4.After the installation of LIC is complete, the system will IPL to the DST primary menu. Note: If using the LIC Install CD (I_Base) to install LIC, the default password for QSECOFR will be uppercase QSECOFR.
5.Take the option to Work with system partitions. (This step does not apply for HMC managed partitions.)
6.Take the option to Recover configuration data. (This step does not apply for HMC managed partitions.)
7.Take the option to Clear non-configured disk unit configuration data. (This step does not apply for HMC managed partitions.)
8.Exit back to the DST primary menu.
9Configure all the disk drives by adding them into system ASP (ASP 1). This writes zeroes on the disk drives so that only the LIC is loaded.

a Select Option 3 - Use DST.
b Work with Disk Units.
c Work with Disk Configuration.
d Work with ASP Configuration.
e Add units to ASPs.
f Type 1 in front of all the available units.
10.When that is complete, power off the system by pressing and holding the power button for five seconds (on older model systems, you may need to press the power button two times to power off the system) .
    The system is clean and ready to go.

    Note: The system does not initialize its disk units to the DoD 5220.22-M standard. For more information, refer to the following Rochester Support Center knowledgebase document:
