D.5 Image-Safe Data Viewer and Editor (zisview and zisedit)

After booting a device from an imaging boot media (PXE, CD, DVD, or ZENworks partition), you can enter zisedit and zisview at the imaging maintenance mode prompt to edit and view the image-safe data for that device.

The following sections contain additional information:

D.5.1 Information Displayed by the Image-Safe Data Viewer

After booting a device from an imaging boot media, enter zisview at the imaging maintenance mode prompt to view the image-safe data for that device.

The image-safe data viewer (zisview) displays the following information about the device:

Information

Image-safe Data

  • Version: The version number of the Novell ZENworks Configuration Management Imaging Agent (novell-ziswin).

  • Just Imaged Flag: If this is set to False, the Imaging Agent reads data from the OS and writes it to the image-safe data store. If this is set to True, the Imaging Agent reads data from the image-safe data store and writes it to the OS.

  • Scripted Image Flag: If this is set to True, the last imaging operation was a scripted image. If this is set to False, the last imaging operation was not a scripted image.

  • Last Base Image: The last base image that was restored to the device.

  • Last Base Image Time: The time stamp of the last base image that was restored to the device.

  • Last Base Image Size: The size of the last base image that was restored to the device.

  • Last Base Image Address: The IP address of the last base image that was restored to the device.

  • Script Checksum: Displays the checksum value representing the last script run. The ZENworks Imaging Engine uses the checksum to prevent the same script from re-running on the device unless you specify in ZENworks Control Center that you want to rerun the same script.

  • LastBaseImageAddr6 Stores the IPV6 address of the server where the last base image was restored.

Workstation Identity Information

If the device is a member of a Management Zone or there is image-safe data present:

  • Zone GUID: The Management Zone that contains the device, if it has been imported.

  • Device GUID: The Globally Unique Identifier of this computer’s device.

If the device is not a member of a Management Zone and image-safe data is not present:

  • Workstation Tree: The tree that contains the device, if it has been created in a tree.

  • Workstation DN: The device’s DN, if known.

  • Workstation ID: The device identification number, if known.

For all devices:

  • Win 9x Computer Name: The computer name for the device.

  • Windows Workgroup: The Microsoft network workgroup of the device.

  • Windows SID: The Windows Security ID of the device, which is a unique number that identifies this device in Windows.

Network Information

  • DHCP: Displays whether this device uses DHCP to obtain its IP address.

  • IP Address: The static IP address that this device uses.

  • Gateway: The gateway that this device uses.

  • Subnet Mask: The subnet mask that this device uses.

  • DHCP6 Displays whether this device uses DHCP to obtain its IPv6 addresses.

  • IP6 Address: The Static IP address that this device uses for IPv6.

  • Gateway6: The gateway that this device uses for IPv6 addresses.

  • prefix6: The prefix that this device uses for IPv6 address.

Production DNS Information

  • DNS Servers: The number of DNS nameservers used for DNS name resolution.

  • DNS Suffix: The DNS context of the device.

  • DNS Hostname: The DNS local hostname of the device. Use this field to change the computer name of the device.

  • DNS6 Servers: The DNS name server used for DNS name resolution of IPv6 address.

Intel iAMT Information

  • iAMT Enterprise Name.  

D.5.2 Using the Image-Safe Data Viewer

To use zisview, enter any of the following commands at the imaging maintenance mode prompt:

Table D-5 Data Viewer Commands

Command

Explanation

zisview

Displays all image-safe data.

zisview -z field

Displays information about a specific field or fields. field is one or more field names separated by a space. field is not case sensitive.

All of the following are valid field names (the corresponding minimum names that can also be entered on the command line follow each field name in parenthesis):

  • JustImaged (J)
  • ScriptedImage (SC)
  • LastBaseImage (L)
  • ZoneGUID (ZoneGuid)
  • DeviceGUID (DeviceGuid)
  • WindowsWorkGroup (WorkG)
  • WindowsSID (SI)
  • WorkstationID (ID)
  • DHCP (DH)
  • IP (IP)
  • Gateway (Gateway)
  • Mask (Mask)
  • DNSServerCount (DNSServerC)
  • DNSServer (DNSServer)
  • DNSSuffix (DNSSu)
  • DNSHostName (DNSH)
  • DHCP6 (DH6)
  • IP6 (IP6)
  • Gateway6 (Gateway6)
  • prefix6 (prefix6)
  • DNS6Server (DNS6Server)

zisview -s

Creates a script that can be used to generate environment variables that contain all of the image-safe data fields.

zisview -h

Displays help for zisview.

D.5.3 Using the Image-Safe Data Editor

After booting a device from an imaging boot media, you can enter zisedit at the imaging maintenance mode prompt to change, clear, or remove information the image-safe data for that device.

To use zisedit, enter any of the following commands at the prompt:

Table D-6 zisedit Commands

Command

Explanation

zisedit

Displays a screen showing all of the image-safe data fields. You can add or change any of the information in the fields.

zisedit field=new_information

You can change the information for one field using this syntax, where field is any valid field name and new_information is the information you want this field to contain. field is not case sensitive.

For example, enter zisedit Mask=255.255.252.0 to enter this information in the subnet mask field.

All of the following are valid field names (the corresponding minimum names that can also be entered on the command line are shown in parenthesis after each field name):

  • JustImaged (J)
  • ScriptedImage (SC)
  • LastBaseImage (L)
  • ZoneGuid (ZoneGuid)
  • DeviceGuid (DeviceGuid)
  • WindowsWorkGroup (WorkG)
  • WindowsSID (SI)
  • WorkstationID (ID)
  • DHCP (DH)
  • IP (IP)
  • Gateway (Gateway)
  • Mask (M)
  • DNSServerCount (DNSServerC)
  • DNSServer1 (DNSServer1)
  • DNSSuffix (DNSSu)
  • DNSHostName (DNSH)
  • DHCP6 (DH6)
  • IP6 (IP6)
  • Gateway6 (Gateway6)
  • prefix6 (prefix6)
  • DNS6Server (DNS6Server)

zisedit -c

Clears all image-safe data fields.

zisedit -r

Removes the image-safe data store.

The image based on the hardware rule is restored only when you delete both the ISD of a registered device and the device object associated with the registered device in ZENworks Control Center. If you want to perform the imaging operations on the device after you delete its ISD only, you must assign the work for the device by using the device object or Rule-Based Imaging.

If a registered device has a device object based on MAC address or Serial number in the database, the device continues to be a registered device when you reboot it after you delete its ISD, Device GUID, and Device data files. The device still gets the imaging work assigned to the device object.

zisedit -h

Displays help for zisedit.

NOTE:To delete a particular dns6server, use the command zisedit dns6serverx=, where x value ranges from 1 to 1350

Example: zisedit dns6server1=

Deletes the first dns6server.
