The Fabric Manager allows you to edit the initial system attributes. Only a field engineer or an administrator can edit the initial configuration using the Fabric Manager.
Prerequisites
The FMPs are configured as FMP 1 and FMP 2.
The FMPs are not configured as a high availability cluster.
FMP1 and FMP2 should be connected to each other via FM LAN.
Notes:
You cannot edit the LAN Subnet IP addresses if a partition image is commissioned on a platform.
You can edit the FM-LAN Subnet from the FMP where the platforms are added. These platforms are added from the FMP that is designated as FMP 1 when it is shipped from Unisys. Reconfiguring the subnet from FMP 1 ensures that the required changes are done in FMP 2 that is connected in the FM LAN.
During the FM LAN subnet IP address change, the Fabric Manager may report the health status of partitionable enterprise partition platforms (PEPPs) as CRITICAL when the connections with the platforms are temporarily interrupted. Use the Event Console to view and close these critical or warning events. If the health status of the PEPPs does not change back to an OK status, use an SSH session to the Fabric Management Platform (FMP) to issue the following command to restart the FFM services:
#rcffmservices restart
The following table describes the various attributes of the system that you can edit:
| System Attribute | Description |
|---|---|
Name | Represents the name of the system (fabric). This name is used as the root node in the hierarchical display of platforms and partitions. The maximum length of the system name can be up to 16 alphanumeric characters along with the character “-”. The name however cannot start with the character “-”. |
Description | Description for the system. It is used to provide a meaningful description of the system (fabric); for example, to which data center it belongs, to which department it is assigned, and so on. The maximum length of the system description can be up to 256 alphanumeric characters along with space, “-” and “.” The length of any word in the description should not exceed 20 characters. |
Sys Style | Represents the Unisys Style number for the host system or product. By default, this field is populated during the Fabric Manager installation. The Forward! system and ClearPath Forward! system have different Sys Style values. By default, the Fabric Manager is configured to use Sys Style codes for the Forward! system. These codes are present in the usr/local/ffm/common/jetty/FFM-PlatformType.conf file. You can edit the Sys Style value based on your system configuration. For more information about editing the Sys Style, see Editing Sys Style. |
FM-LAN Subnet | An Ethernet LAN that interconnects the Fabric Management Platform, enterprise partition platforms, and running partitions for management functions. |
IP-LAN Subnet | An Ethernet LAN that interconnects the partition images within an enterprise partition platform and across different enterprise partition platforms. The IP LAN uses the high-speed InfiniBand physical connection. The IP LAN subnet address can be changed only during the fabric installation. |
HD-LAN Subnet | An Ethernet LAN that interconnects the Windows partition images within a given partitionable enterprise partition platform so that application modules on other partitions may communicate. Note: Some earlier levels of the ClearPath Forward fabric supported the Host Data LAN (HD LAN). This is an internal Ethernet LAN that routes Interconnect traffic within the platform to Windows partitions and serves as a gateway for Windows partitions to communicate with partitions residing on different enterprise partition platforms. Although the current ClearPath Forward release does not use the HD LAN, for backward compatibility reasons partitions created under the current release can communicate with Windows partitions created under earlier releases and do use the HD LAN. |
Platform Name | Represents the name of the Fabric Manager Platform. The maximum length of the platform name can be up to 16 alphanumeric characters along with the character “-”. The name however cannot start with the character “-”. |
Platform Description | Description for the Fabric Manager Platform. The maximum length of the description can be up to 256 alphanumeric characters along with space, “-”, and “.”. The length of any word in the description should not exceed 20 characters. |
Synchronize with NTP Server | Available options are Yes or No. Configures the Fabric Manager to use the Network Time Protocol (NTP) server to synchronize the date and time (and time zone, if applicable) across various components of the fabric, such as the Fabric Manager, platform management card, s-Par®, partitions, and so on. If you do not wish to configure the Fabric Manager to use an NTP server, then you can set the date, time, and time zone attributes manually. |
Date | Date selected for the fabric. |
Time | Time selected for the fabric. |
Time Zone | Time Zone selected for the fabric. |
NTP Server IP(s) | IP address of the NTP server. You can add, delete, and set the Primary NTP Server. Note: This field is available only if you have selected the Synchronize with NTP Server option. |
To edit the system (fabric) attributes
On the Fabric Manager user interface, point to System Administration, and then click CPF System.
The Details: CPF-System screen appears on the right pane.
In the Summary tab, click Edit.
The Edit System screen appears.
In the System Details tab, you can edit the following:
Name
Description
Sys Style
Click Next.
In the LAN Subnets tab, you can edit the default Subnet. These attributes can be changed if you have different subnet IP addresses. You can change the default IP addresses of the following groups:
FM-LAN Subnet
IP-LAN Subnet
HD-LAN Subnet
Notes:
The IP addresses should meet the following requirements:
Class ‘A’: First Octet should be between 1 and 126
Class ‘B’: First Octet should be between 128 and 191
Class ‘C’: First Octet should be between 192 and 223
Unisys recommends the use of private IPV 4 address spaces.
The Fabric Manager does not allow you to change the IP-LAN Subnet if the secure fabrics are already discovered but there is no active platform with s-Par version 4.3.x.
Click Next.
In the Management Platform Network tab, you can edit the following platform details:
Platform Name
Platform Description
Platform Number
Click Next.
In the Time Source tab, you can choose to synchronize the Fabric Manager with an NTP server.
Note: Ensure that maintenance mode is turned off before editing the time settings in this tab. Any change made to the time setting affects the maintenance mode schedule.
In the Synchronize with NTP Server option, if you choose
Yes option, then you can edit the time zone. You can also add the NTP servers and delete them from the available list.
Note: You can set the NTP server if the FMP is in clustered environment and running node is master.
No option, then you can edit the date, time, and time zone.
Note: The default value for Synchronize with NTP Server is No.This field is either disabled or enabled depending the settings applied during the previous edit system settings.
