Xerox FreeFlow Print Server 6.0 Disk Overwrite

Dear Customer: This kit contains the DocuSP Disk Overwrite software supporting all DocuSP-based printing products that meet the

minimum disk size requirements as described below.

Overview

The Disk Overwrite software removes all data from the spool, swap, and outQ partitions of the DocuSP hard disk. The data cannot be retrieved. Data is overwritten in four passes using different patterns written to the entire disk or section of the disk. This four-pass algorithm conforms to U.S. Department of Defense Directive 8500.1. Of the four passes, the third pass is used to write 0x40404040 and the last pass is to verify (by reading and comparing) 0x40404040. An option is provided to perform a single pass (fast mode) disk overwrite.

The data overwrite operation does not process defective or spare blocks for SCSI and FCAL drives. It also does not perform any special disk error recovery. If a higher secure data overwrite scheme is required, the Sun Solaris Format command Purge utility is available. Additionally, 3

party software with more flexibility and functions, such as

UniShred Pro is available. However, it is not part of the DocuSP software nor is it supported by DocuSP. The Disk Overwrite procedure can be initiated from the DocuSP interface or from a UNIX command line.

Requirements

• DocuSP version 3.8 or higher

• If running DocuSP 3.8, the Solaris Operating System version 8 for Disk Overwrite software only is required

(part number 301E54050).

NOTE: For systems originally installed with DocuSP 3.8 or earlier, a full scrape and new installation of the Solaris Operating System is required to partition the drive for the Disk Overwrite functionality. All saved jobs, fonts, forms, resources, and any other customer-installed software are deleted during the installation.

• Minimally two 18 Gbyte disks or one 36 Gbyte disk in the Sun platform in order to support the disk partitioning

• Disk Overwrite license enabled and activated on the DocuSP.

Installation

The DocuSP Disk Overwrite software is installed by a Xerox Service Representative following the instructions in the

Installing the Disk Overwrite Software section of this document. NOTE: If a scrape install is required, all saved jobs, fonts, forms, resources, and any other customer-installed

software saved on the DocuSP controller hard disk must be backed up to another medium prior to installation.

Pre-installation procedures

Before the Disk Overwrite software can be installed, the following must be completed:

1. If a scrape is required, back up all saved jobs, fonts, forms, resources, and customer-installed software. This is the responsibility of the customer.

2. If DocuSP 3.8 is installed on the system, the Xerox Service Representative installs the Solaris Operating System version 8 for Disk Overwrite. This installation

If the system is running a version of DocuSP later than 3.8, a scrape is necessary ONLY if the system has not been scraped since the upgrade to DocuSP 4.X or higher. Use the Solaris Operating System version delivered with the DocuSP software to perform the scrape.

If the system is running DocuSP 4.2 on a Sun W1100Z controller, the DocuSP Disk Overwrite 4.2 Self Install Patch is required. The patch should be installed prior to the Disk Overwrite software installation. Refer to the patch installation instructions provided with the Patch CD.

If the system is running DocuSP 50 or higher, two options are presented during the operating system installation:

• Data Overwrite is planned to be used on this system

• Backup is planned to be used on this system

Both options must be checked in order to run the Disk Overwrite software. If these two options were not checked, a scrape install of the system is required and the two options checked.

NOTE: If the Disk Overwrite software is reinstalled for any reason, for example to change the partitioning, it is not necessary to reinstall the Solaris Operating System.

requires a scrape and repartition of the hard disk(s).

Installing the Disk Overwrite software

To install the Disk Overwrite software:

1. Insert the Disk Overwrite CD into the CD/DVD ROM drive.

2. A window opens and a log-in prompt displays.

3. Enter the root password and press <Enter>.

NOTE: For certain security settings on DocuSP, automatically installing software on a CD may be prohibited. If the Disk Overwrite CD is inserted into a CDROM or DVDROM drive and a window does not open after the CD has been detected, manually install the software by opening a terminal window, logging in as root, and entering the following command to start the installation process:

/cdrom/cdrom0/volstart

WARNING: Do not run any other programs on the CD to load the software. An improper installation could result in unknown side effects and cause the system to be unstable.

4. Answer Y (yes) to the package installation questions.

5. Once the package is installed, the system provides the following Disk Overwrite installation directions:

a) Enter the type of verification to perform after sanitizing the disk(s).

Input S for Sample verification or F for Full verification:

For example: Enter S for 10% sample verification or F for full verification.

CAUTION: It is strongly recommended you accept the default settings for the partitioning when the software is initially installed and run the Disk Overwrite process

once.

Although the setup procedure allows you to re-size each data partition to improve Disk Overwrite performance, reducing the size of a partition may leave sensitive data on the unused portion of the disk.

NOTE: The system reboots automatically after the repartition process is finished.

b) Do you wish to re-size the /var/spool/XRXnps/outQ partition?(Y/N)

Enter Y to resize or N to use the default values. If Y is entered, the following information appears:

The current partition size is XX Gbytes.

If N is entered, the system uses the default values and the setup procedure exits.

c) Enter new partition size in gigabytes [Min, Max]

Please wait, it may take a few minutes. Upon completion, the following message appears:

Resizing of /var/spool/XRXnps/outQ has been successfully completed.

d) Do you wish to re-size the /var/spool/XRXnps partition? (Y/N)

Enter Y to resize or N to use the default values. If Y is entered, the following information displays:

The current partition size is XX Gbytes. If N is entered, the system uses the default values, the setup procedure exits, and the system

reboots.

e) Enter new partition size in gigabytes [Min, Max]

Please wait, it may take a few minutes. Upon completion, the following message appears:

Resizing of /var/spool/XRXnps has been successfully completed.

The system reboots in a few seconds.

NOTE: Disk Overwrite does not work without a valid license.
