z/OS® element or feature | Additional hardware requirements for z/OS V2R2 elements and features |
---|---|
Alternate Library for REXX | None. |
BCP | Automatic tape switching requirements for 3480, 3490, 3590, or 3592 tape drives: A single I/O device should
have a single device number (defined through HCD) across the entire
sysplex, and that number should not be reused for any other device.
For ease of management, you should use the same device number on all
systems to represent an automatically switchable device. If an automatically
switchable device is a 3480 without the Read Configuration Data Capable
function, you must use the same device number on all systems. Note
that, if you have not already applied C05566E, device numbers must
be the same. Note: 3592 tape devices are defined through HCD as device type
3590-1, the same as 3590 devices.
Automatic IPL (autoIPL) requirement:
Enablement of autoIPL in multisystem-capable sysplexes with SFM active: The use of autoIPL in multisystem-capable sysplex configurations where a sysplex failure management (SFM) policy is active is supported. With this support, requested autoIPL actions are performed in accordance with the DIAGxx parmlib member, even when an SFM policy is active in the sysplex. For System z10 systems, use of autoIPL on a system
in a multisystem-capable sysplex configuration where an SFM policy
is active requires the following licensed internal code (LIC) levels
to be installed:
Flash Express®, which supports storage-class memory (SCM) on Flash Express cards as optional auxiliary storage, is available on the z13 or z13s server, and on the zEC12 or zBC12 server with FC #0402. Global resource serialization: If any systems are in a global resource serialization ring complex but not in the sysplex, global resource serialization requires basic mode CTCs to communicate with those systems. |
BCP (continued) | XCF (cross-system coupling facility) requirements in a sysplex
configuration with one central processor complex (CPC):
In a sysplex configuration with two or more central processor
complexes (CPCs), XCF requires all of the following:
The use of Parallel Sysplex functions, such as data sharing, requires a Coupling Facility. The IBM® zEnterprise Application
Assist Processor (zAAP) is a specialized processing unit that provides

Extended address volumes (EAVs): To use this function, an IBM System Storage® DS8000® with Licensed Machine Code (LMC) level 5.4.0xx.xx (bundle version 64.0.xx.xx) or later is required. Extended remote copy (XRC): When migrating data with XRC, the primary storage device must be attached to an XRC-capable storage subsystem, such as an Enterprise Storage Server® with applicable feature licenses enabled. Peer-to-peer remote copy (PPRC): When migrating data with PPRC, the primary and secondary storage devices must be attached to a PPRC-capable storage subsystem, such as an Enterprise Storage Server with applicable feature licenses enabled. OAM File System support: To use a file system sublevel configured with an NFS file system mounted in the z/OS UNIX hierarchy, an NFS server compatible with the z/OS NFS client is required. OAM Parallel Sysplex support: To use this OAM object support capability, coupling facility hardware or a supported simulated environment is required. OAM System Managed Tape Support: To use this support in an automated tape library environment, an IBM automated tape library or an IBM Virtual Tape Library is required. To use this support in a manual tape library environment, stand-alone tape drives are required. Storage management subsystem system groups: Some SMS complex configurations might require DASD with enhanced connectivity. Because all systems in an SMS complex share the same configuration data sets, the ACDS and the COMMDS must reside on DASD devices that are accessible to the system activating the configuration. VSAM record level sharing (RLS): A coupling facility (at least one) must be connected to all systems capable of VSAM RLS. For multiple coupling facilities, select one facility with global connectivity to contain the master lock structure. The coupling facility must be at control level 2. It must be large enough to contain either a lock or a cache structure, or both, and have enough surplus space to allow the structures to be modified. The cache structures must be defined to SMS to enable it for VSAM RLS. WORM Tape Support: Requires the IBM 3592 Enterprise Tape System and WORM tape media, or the logical WORM support in the IBM TS7700 Virtualization Engine. |
DFSMSdss | Concurrent copy: To use this function, data must reside on
DASD volumes attached through a concurrent copy-capable storage subsystem. Defining and accessing extended format sequential data sets through BSAM and QSAM: Extended format data sets must reside on DASD attached through cached storage controls and an ESCON or FICON channel adapter. Fast replication: To use this function you need DASD attached to a FlashCopy® capable storage subsystem, such as DS8000. |

(such as terminals and workstations) and existing telecommunications
software (such as VTAM® and
TCP/IP) that run on z/OS to
be used. For 3270 support, most 3270 type terminals or 3270 emulators
in a z/OS network from which
a user can interactively log on to TSO/E are supported by z/OS UNIX services
and include:
For ASCII control sequence support from 3270 displays,
the OMVS command, with the pseudoterminal functions, maps and transforms
a 3270 TSO/E terminal interface and user externals to the POSIX 1003.1
defined terminal interface expected by POSIX compliant user processes,
including the POSIX 1003.2 Shell. This mapping consists of:
For ASCII terminal interface, UNIX workstations and other workstations in a TCP/IP network that support the telnet or rlogin virtual terminal protocols can directly login to the z/OS shell through Communications Server. The supported ASCII terminal interface conforms to X/OPEN Issue 4, Version 2. |
