Configuration of a sysplex on LPAR and Non-LPAR systems z/OS MVS Setting Up a Sysplex SA23-1399-00 |
|
Figure 1 shows the connections required to connect two processors, one of which runs two MVS™ images on PR/SM™. It also illustrates redundant sysplex couple data sets, channels, signaling paths, and Sysplex Timers. In this configuration, a failure on any one channel, path, ESCD,
or sysplex couple data set does not bring down the sysplex. In case
of a failure, MVS can use a different
sysplex couple data set, channel, path, ESCD, or Sysplex Timer to maintain
sysplex operation.

of a Sysplex on LPAR and Non-LPAR Systems
Note: If you have PR/SM installed
with the ESCON® Multiple Image
Facility (EMIF), you can share ESCON channels
among logical partitions. For information about EMIF and shared channel
paths, see PR/SM Planning Guide and z/OS HCD Planning.
