workload on disk arrays spread across two or more sites up to 40 km (20 miles) apart. With this
support, users who are running IBM Parallel Sysplex systems can take advantage of the P9500's
suite of remote copy options for data availability.
GDPS operations feature automatic control of groups of PPRC-managed volumes using host-based
scripts and PPRC commands; for example, CGROUP (FREEZE/RUN). GDPS support may have
additional installation requirements for Continuous Access Synchronous Z main and remote system,
depending on the P9500 firmware and Continuous Access Synchronous Z versions.
Check the following items with your HP representative:
The P9500 does not support controlling the FREEZE Option through the CESTPATH LINK
parameter. The FREEZE Option must be controlled using the CGROUP option of CESTPATH.
Please make changes as needed to the CESTPATH LINK definitions in your GDPS configuration
files or configuration database.
For more information on GDPS, see the following IBM publications: Geographically Dispersed
Parallel Sysplex: the S/390 Multi-site Application Availability Solution, Executive Summary
(GF22-51 14); and Geographically Dispersed Parallel Sysplex: the S/390 Multi-site Application
Availability Solution (GF22-5063).

RMF PPRC Link-path statistical information support

When you use z/OS Resource Measurement Facility (RMF), and if you specify the IBM TotalStorage
Enterprise Storage Server (ESS), you can acquire PPRC Fibre Link-path statistical information.
If the total size of the data for the data-acquisition interval is 100 KB and below, zero may be
reported for the data size.
The following two tables show P9500 system adaptor IDs (SAID) for the LINK parameters (ports)
that display when PPRC Link-path statistical information is acquired with RMF.
The P9500 system adaptor ID (SAID) values in the following tables are different from the ones for
the LINK parameters of CESTPATH TSO commands (see
16)).
