Enhanced Driver Maintenance - IBM z13s Technical Manual

Redundant humidity sensors
Redundant altimeter sensors
Corrosion sensors
Unified support for the zBX
The zBX is supported the same as any other feature on z13s servers.
Single processor core checkstop and sparing
This indicator implies that a processor core has malfunctioned and has been
support personnel must consider what actions to perform, and also consider the history of
z13s servers by asking the question, "Has this type of incident happened previously on
this server?"
Hot swap PCIe / InfiniBand hub cards
When properly configured for redundancy, hot swapping (replacing) these InfiniBand and
PCIe fanout cards is possible:
– HCA2-optical, or HCA2-O (12xIFB)
– HCA3-optical, or HCA3-O (12xIFB)
– ICA-SR
– PCIe Gen3
This feature avoids any kind of interruption when the need for replacing these types of
cards occurs.
Redundant 1 gigabits per second (Gbps) Ethernet (GbE) support network with virtual local
area network (VLAN)
The support network in the machine gives the machine code the capability to monitor each
internal function in the machine. This capability helps to identify problems, maintain
redundancy, and provide assistance while concurrently replacing a part. Through the
implementation of the VLAN to the redundant internal Ethernet support network, the VLAN
makes the support network itself easier to handle and more flexible.
PCIe I/O drawer
The PCIe I/O drawer is available for z13s servers. It can be installed concurrently, as can
all PCIe I/O drawer-supported features.

9.4 Enhanced Driver Maintenance

EDM is one more step toward reducing both the necessity for and the duration of a scheduled
outage. One of the components to planned outages is LIC Driver updates that are run in
support of new features and functions.
When correctly configured, z13s servers support concurrently activating a selected new LIC
Driver level. Concurrent activation of the selected new LIC Driver level is supported only at
specific released sync points. Concurrently activating a selected new LIC Driver level
anywhere in the maintenance stream is not possible. A concurrent update/upgrade might not
be possible for certain LIC updates.
Consider the following key points of EDM:
The HMC can query whether a system is ready for a concurrent driver upgrade.

The current implementation is just for collecting field data for analysis. System operation will not be affected by the
availability or functions of this sensor.
