easily. IBM zAware provides a simple GUI for easy identification of message anomalies,
which can facilitate faster problem resolution.
IBM zAware is enhanced as part of z13s general availability to process messages without
message IDs. This feature allows you to analyze the health of Linux operating systems by
analyzing Linux SYSLOG. Linux on z Systems running natively and as a guest on z/VM is
also supported. It must be a Linux distribution that has been tested for the z Systems server
on which it runs.
7.7.1 z Appliance Container Infrastructure mode LPAR
IBM zAware is ordered through specific features of z13s, and requires z/OS V1R13 or later
with IBM zAware exploitation support to collect specific log stream data. It requires a correctly
configured LPAR. For more information, see “The z Appliance Container Infrastructure- mode
LPAR” on page 244.
During a driver upgrade for z13 servers from Driver 22 to Driver 27, an existing zAware mode
LPAR will be automatically converted to zACI LPAR type. With Driver 27 and later, any new
zAware host will be deployed in an LPAR of type zACI.
To use the IBM zAware feature, complete the following tasks in z/OS:
1. For each z/OS that is to be monitored through the IBM zAware client, configure a network
connection in the TCP/IP profile. If necessary, update the firewall settings.
2. Verify that each z/OS system meets the sysplex configuration and OPERLOG
requirements for monitored clients of the IBM zAware virtual appliance.
3. Configure the z/OS system logger to send data to the IBM zAware virtual appliance
server.
4. Prime the IBM zAware server with prior data from monitored clients.
For each Linux system to be monitored, complete these steps:
1. Configure a network connection. If necessary, update the firewall settings to ensure
secure communications between IBM zAware and Linux clients.
2. Configure the syslog daemon of the Linux system to send messages to the IBM zAware
server.
For more information about zAware, see Appendix B, “IBM z Systems Advanced Workload
Analysis Reporter (IBM zAware)” on page 453 and the latest guide on Resource Link at the

7.8 Coupling facility and CFCC considerations
Coupling facility connectivity to a z13s is supported on the z13, zEC12, zBC12, z196, z114,
or another z13s server. The LPAR running the CFCC can be on any of the previously listed
supported systems. For more information about CFCC requirements for supported systems,
see Table 7-63 on page 294.
