Configure Time and Time Zone
Unisys-supplied Linux partition images are set to use UTC by default. If applicable, set the correct time zone and time for your location.

The Linux Online Updates setting is not configured in the Unisys-supplied Linux images. If applicable, configure the Linux Online Updates setting and install any desired updates.
Registering a SUSE Linux Partition with Novell Customer Center
All SUSE Linux Enterprise Server (SLES) operating systems purchased from Unisys for a partitionable enterprise partition platform (PEPP) can be registered with the SUSE Customer Center to receive additional software, updates, bug fixes, and security patches through a single unlimited virtualization subscription.
To register a SUSE LINUX partition with a subscription activation key, do the following:
Launch the YaST Control Center.
Select Other in the left column.
The Other selections are displayed.
Select Novell Customer Center Configuration in the right column to launch the application.
The Novell Customer Center Configuration window appears.
Select the Configure Now (Recommended) option, ensure minimally the Registration Code check box is checked, and then click Next.
The Novell Customer Center System Registration page appears.
Type in the email address for your Novell Customer Center account and the activation code associated with the platform hosting your partition, and then click Submit.
Note: If you have multiple organizations configured in the Novell Customer Center, and this is the first partition you are registering using a particular activation code, you may be required to select the appropriate organization from the displayed list.
Configure MTU Size
The default maximum transmission unit (MTU) size for each InfiniBand interface is set to 1500 Byte packets. If your Linux partition will be communicating with Windows partitions in the secure fabric and large Jumbo Packet sizes are required, set the MTU size for each InfiniBand interface to 2044 to ensure smooth data transmission over the IP-LAN secure fabric.
To configure the MTU size, navigate to the /etc/sysconfig/networking/ directory for SUSE or the /etc/sysconfig/network-scripts/ directory for RHEL, access the interface configuration file ifcfg-bondX.YYYY (where X.YYYY identifies the vBDF and secure fabric subnet tag PKEY for the interface respectively), locate the MTU=<value> line, and then set or change the <value> parameter to 2044.
Note that the MTU size must be set to the same value across all interfaces that will communicate with each other. That is, if an interface is in a Windows partition, be sure to use the Windows operating system Device Manager MMC snap-in to set or change the MTU size value for all InfiniBand interfaces of the Windows partition to 2044.
