ClearPath IX Systems Installation and Configuration Guide

Customizing the Site
See the documentation for your version of UnixWare for details about installing optional
products.
16.8. Repartitioning the UnixWare Node
Following initial installation, a site may wish to repartition UnixWare. The only method
for doing that, without reinstalling UnixWare, is to create a new partition in the
unallocated free space that was not partitioned during installation. See the ClearPath IX
Operations Guide for instructions.
16.9. Configuring Resilient Partitions (2200 Node)
Sites can configure the 2200 node for resilient partitions as shown in Figure 16–1. During
normal operation, the 2200 node connects to the FDDI LAN and communicates with the
Intel node through the primary connection. Whenever the primary partition is unavailable,
the resilient connection automatically is made available and communication switches from
the primary path to the resilient path.
Take the following steps to configure resilient partitions:
1. Configure the resilient connection in the operations database (ODB) using the Site
Configuration Management System (SCMS). This is the responsibility of whoever
generates the ODB. For more information on using SCMS to configure a resilient
connection, see the SCMS Administration Guide Volume 1.
2. The resilient connection must be configured in CMS 1100 by site personnel using the
Integration Expert Config Ace tool.
Notes:
• The second 2200 node partition is OS 2200 only. The CMS 1100 configuration for
the second partition cannot contain heterogeneous multiprocessing (HMP)
interconnect components that allow the resilient connection to access the Intel node.
Thus, the two partitions cannot run together as two instances of a ClearPath IX
system.
• When configuring the resilient connection in the ODB using SCMS, the name
FDDIVI must be assigned to the first FDDI control unit and FDDIVJ to the second
control unit (see Appendix D). Those names are required by automated
configuration tools.
