Program Directed re-IPL
Program Directed re-IPL is designed to enable an operat-
ing system to determine how and from where it had been
loaded. Further, Program Directed re-IPL may then request
that it be reloaded again from the same load device using
the same load parameters. In this way, Program Directed re-
IPL allows a program running natively in a partition to trigger
a re-IPL. This re-IPL is supported for both SCSI and ECKD
devices. z/VM 5.3 provides support for guest exploitation.
FICON Link Incident Reporting
FICON Link Incident Reporting is designed to allow an
operating system image (without operating intervention)
to register for link incident reports, which can improve the
ability to capture data for link error analysis. The informa-
tion can be displayed and is saved in the system log.
Serviceability Enhancements
Requests Node Identification Data (RNID) is designed to
facilitate the resolution of fiber optic cabling problems. You
can now request RNID data for a device attached to a na-
tive FICON channel.
Connectivity for LANs – Open Systems Adapters
Networking enhancements for the OSA-Express family
of features are designed to facilitate serviceability, help
simplify the infrastructure, facilitate load balancing, reduce
latency, improve performance, and allow ports to be com-
bined in a single logical link for increased throughput and
nondisruptive failover.
Local Area Network (LAN) connectivity for the z10 EC is
being enhanced with the introduction of a dual port Open
Systems Adapter-Express3 (OSA-Express3) 10 Gbps Long
Reach. Open Systems Adapter-Express2 (OSA-Express2),
continues to be supported on the z10 EC for connectivity
to Local Area Networks (LANs), and supports 1000BASE-T
Ethernet, Gigabit Ethernet (GbE) LX and SX, and 10 GbE
LR. When OSA-Express3 10 GbE LR becomes available,
OSA-Express2 10 GbE LR will no longer be available for
ordering.
The OSA-Express3 and OSA-Express2 features are
hot-pluggable, support the Multiple Image Facility (MIF)
™
sharing of channels across logical partitions, and can be
defined as a spanned channel to be shared among logical
partitions within and across LCSSs. The maximum com-
bined number of OSA-Express3 and OSA-Express2 fea-
tures supported per server is 24 on the z10 EC (up to 48
ports). OSA-Express2 features can be carried forward on
an upgrade from a z9 EC, z990 or z900 server. The OSA-
Express features are not supported on z10 EC servers.
The OSA-Express2 1000BASE-T Ethernet feature and the
OSA-Express2 Gigabit Ethernet (GbE) feature support
the IBM Communication Controller for Linux (CCL) on the
System z platform. The OSA-Express2 OSN (OSA for NCP)
supports the Channel Data Link Control (CDLC) protocol,
which provides direct access from the host operating sys-
tem (such as z/OS and TPF) to the CCL.
With the large volume and complexity of today's network
traffic, the z10 EC offers systems programmers and
network administrators the ability to more easily solve net-
work problems. With the introduction of the OSA-Express
Network Traffic Analyzer and QDIO Diagnostic Synchro-
nization on the System z and available on the z10 EC,
customers will have the ability to capture trace/trap data
and forward it to z/OS 1.8 tools for easier problem determi-
nation and resolution.
This function is designed to allow the operating system
to control the sniffer trace for the LAN and capture the
records into host memory and storage (file systems), using
existing host operating system tools to format, edit, and
process the sniffer records.
