and control the zBX model 004. With the zBX model 004, the concept of owning the CPC
does not exist. Because the system upgrade is always disruptive, the zBX upgrade will also
be a disruptive task.
If installing a new build z13s server and planning to take over an existing zBX attached to
another existing CPC, and the zBX is not a model 004, the zBX conversion to a zBX model
004 can be done during the installation phase of the z13s server.
The following are some of the features and functions added by the zBX Model 004. Model 004
includes all of the enhancements implemented in zBX Model 003.
򐂰 Stand-Alone node based zBX defined as an ensemble member to the ensemble HMCs.
򐂰 Direct management connection to server eliminated with node-based zBX Model 004.
򐂰 Two SEs installed in the zBX Model 004.
򐂰
Firmware updates and service activities are no longer linked to the z Systems CPC.
򐂰 No need for a direct intranode management network (INMN) link between CPC and zBX.
Configuration and connectivity complexity is reduced and resiliency improved.
򐂰 Synchronized time from HMC by using Network Time Protocol (NTP).
򐂰 Workload Optimization mapped to SLA requirements available with zManager and zBX
Model 004.
򐂰 Available only as an upgrade from zBX Model 002 and from a zBX Model 003.
򐂰 No new blade types will be announced or delivered. As of December 31, 2014, all
supported Blades have been withdrawn from marketing (WDfM).
򐂰
Except for DataPower XI50z Blades, supported x and p blades might still be available from
distributors or on the used market.
򐂰 Empty slot entitlements for x and p blades, if already existing, can be populated.
򐂰 New entitlements for blades were WDfM as of December 2015.
򐂰 Consider upgrading zBX to a Model 004 until withdrawn (WDfM date not announced).
8.4 Permanent upgrade through the CIU facility
By using the CIU facility (through the IBM Resource Link on the web), you can start a
permanent upgrade for CPs, ICFs, zIIPs, IFLs, SAPs, or memory. When performed an
upgrade through the CIU facility, you add the resources yourself. IBM personnel do not have
to be present at your location. You can also unassign previously purchased CPs and IFL
processors through the CIU facility.
The capability to add permanent upgrades to a z13s server through the CIU facility requires
that the permanent upgrade enablement feature (FC 9898) be installed on the z13s server. A
permanent upgrade might change the MCI if additional CPs are requested or the change
capacity identifier is part of the permanent upgrade. However, it cannot change the z13s
model from an N10 to an N20. If necessary, more LPARs can be created concurrently to use
the newly added processors.
Planning: A permanent upgrade of processors can provide a physical concurrent upgrade,
resulting in more enabled processors available to a z13s configuration. Therefore,
additional planning and tasks are required for
nondisruptive
logical upgrades. See
“Suggestions to avoid disruptive upgrades” on page 353 for more information.
