||Keeping HCM configuration files on the host
by Jochen Hoffmann
Until today, users of Hardware Configuration Manager (HCM) had to keep their configuration files on the Windows PC where HCM is running. Customers consider their HCM configuration business-critical data and would prefer to store it on the host in order to
- have it protected by the security and the backup/recovery mechanisms offered by the host
- simplify sharing the configuration among several users
- keep the HCM configuration near the closely related I/O Definition File (IODF)
These issues are addressed in the z/OS 1.9 version of HCM:
- It provides the option to use a Master Configuration File (MCF).
- An MCF is an HCM configuration stored on the host.
- Each user still has a local copy that is automatically kept synchronized with the MCF, thus allowing to sequentially share the configuration among several users safely.
- Standalone processing is still possible and supported by MCF's mismatch resolution mechanism.
||Keeping perspective on complex I/O configurations
by Sigrun Elsner
One challenge in I/O configuration management is controlling the inherent complexity of maintaining both the logical and physical configuration data. Hardware onfiguration
Manager (HCM) allows you to define both of these aspects with a single graphical user interface.
Typically, many are involved in bringing a configuration to life:
system programmers who define it, storage planners specifying requirements, those familiar enough with cables and adapters to make the physical connections between hardware components - to name just a few groups. Often, they are not primarily interested in the graphical view - instead, they need accurate and complete reports in order to quickly make reliable assessments about or compare complex configurations.
HCM provides a wide variety of such reports that can be saved to files in a variety of formats. These files can easily be distributed and viewed by those who need to know different aspects and varying degrees of detail about the I/O configuration.
The article surveys the many additions and improvements brought to the HCM reporting facilities since the z/OS 1.7 version.
