8.3 Miscellaneous equipment specification upgrades
MES upgrades enable concurrent and permanent capacity growth. MES upgrades enable the
concurrent addition of processors (CPs, ICFs, zIIPs, IFLs, and SAPs), memory capacity,
I/O ports, hardware, and entitlements to the zBX. MES upgrades enable the concurrent
adjustment of both the number of processors and the capacity level. The MES upgrade can
be done by using LICCC only, by installing an additional CPC drawer, adding I/O cards, or a
combination:
򐂰 MES upgrades for processors are done by any of the following methods:
– LICCC assigning and activating unassigned PUs up to the limit of the installed CPC
drawers.
– LICCC to adjust the number and types of PUs, to change the capacity setting, or both.
– Installing an additional CPC drawer, and LICCC assigning and activating unassigned
PUs in the installed drawer.
򐂰 MES upgrades for memory are done by either of the following methods:
– Using LICCC to activate extra memory capacity up to the limit of the memory cards on
the currently installed CPC drawers. Plan-ahead memory features enable you to have
better control over future memory upgrades. For more information about the memory
features, see 2.4.4, “Memory upgrades” on page 63.
– Installing an additional CPC drawer, and using LICCC to activate extra memory
capacity on the installed CPC drawer.
򐂰 MES upgrades for I/O are done by the following method:
– Installing additional I/O cards and supporting infrastructure, if required, in the
I/O drawers or PCIe I/O drawers that are already installed, or installing extra PCIe
I/O drawers to hold the new cards.
򐂰
MES upgrades for the zBX can only be performed through your IBM service support
representative (SSR) and are restricted to add Blades to existing entitlements.
An MES upgrade requires IBM service personnel for the installation. In most cases, the time
that is required for installing the LICCC and completing the upgrade is short. To better use the
MES upgrade function, carefully plan the initial configuration to enable a concurrent upgrade
to a target configuration.
By planning ahead, it is possible to enable nondisruptive capacity and I/O growth with no
system power down and no associated power-on resets (PORs) or initial program loads
(IPLs). The availability of I/O drawer and PCIe I/O drawers has improved the flexibility to
perform unplanned I/O configuration changes concurrently.
