Sysplex Timer Licensed Internal Code Upgrade
The Sysplex Timer's Licensed Internal Code (LIC) has been upgraded to support using STP in a Mixed Coordinated Timing Network (CTN). The required Sysplex Timer LIC is shipped along with the STP feature, and must be installed by the IBM Service Support Representative prior to migrating from a Sysplex Timer based External Time Reference (ETR) network to any STP Coordinated Timing Network (CTN).
Hardware Management Console
Management of STP-enabled servers requires V2.9.1 Licensed Internal Code (LIC) of the Hardware Management Console (HMC) application. Previously installed HMCs (Feature Codes 0075 and later) can be upgraded to V2.9.1 LIC by requesting your IBM Service representative to order ECA 241 for each server that has one or more HMC features to be upgraded.
If an existing HMC is to be loaded with the new HMC LIC, the attached servers will first need to be at specific driver levels and may need specific MCLs to be installed. These MCLs may be loaded without an outage, as long as the server is at the driver level listed. If you need to upgrade the server to the required driver level, an outage will be necessary.
- z990 and z890 (Driver 55)
- z900 and z800 (Driver 3Gf)
- 9672 G5, G6, and Multiprise(R) 3000 (models H55 or H75 only) (Driver 26)
- MCL 174 for EC F99918
- MCL 009 for EC J11172
- MCL 009 for EC J10392
- MCL 006 for EC J11920
EC Levels and MCLs for STP support
z9 EC, z9 BC, z990, z890 servers and Coupling Facilities can be made STP-capable by installing required STP Licensed Internal Code (LIC). The LIC may be installed concurrently. The following are the STP LIC requirements:
- z990 and z890
- The z990 and z890 must be at EC Driver level 55. Prior to installing the STP Feature Code, have your SSR download and install all of the latest MCLs that are available for this driver. Several STP prerequisite MCLs will be installed as a result
- IBM System z9
- The z9 EC and z9 BC must be at EC Driver level 63. Prior to installing the STP Feature Code, have your SSR download and install all of the latest MCLs that are available for this driver. Several STP prerequisite MCLs will be installed as a result
After the MCLs are installed, the z990 and z890 become STP-capable servers. STP functions cannot be used until the STP enablement feature is installed.
No changes are necessary on System z10 servers to make them STP capable. The STP Feature code still needs to be ordered to make them STP enabled.
Enabling hardware feature for STP
Feature #1021 is required for your server or Coupling Facility to enable STP on your hardware. This is a chargeable feature for each server and Coupling Facility.
Feature #1021 provides the following.
- Installation instructions are provided. The IBM Service Support Representative (SSR) will perform this part of the installation
- A required Sysplex Timer EC LIC disk is provided. This LIC should be installed on any Sysplex Timer where there is a migration planned from ETR network to any CTN configuration. This should be installed prior to installing the server enablement LIC
- A required server or Coupling Facility MCL diskette or CD is provided. This MCL enables STP
Feature #1021 should be installed on any STP-capable server or Coupling Facility that will be used in a Mixed CTN or STP-only CTN. STP enablement LIC can be loaded without disruption to current operations. The loading of the enablement LIC is done via the server's Support Element.
Machine Change Levels (MCLs) are required. Descriptions of the MCLs are available now through Resource Link.
MCLs are designed to be applied concurrently. Contact IBM service personnel for further information.
