BCP Automatic tape switching requirements for 3480, 3490, 3590, Start of changeor 3592End of change 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: Start of change3592 tape devices are defined through HCD as device type 3590-1, the same as 3590 devices.End of change
Automatic IPL (autoIPL) requirement:
  • The no-charge SCSI IPL hardware feature (#9904) is integrated on the zEnterprise® servers and z Systems™ z10™ and later servers. That is, no features are required on the z13™, Start of changez13sEnd of change, zEC12, zBC12, z196, z114, or z10 servers.
  • z/OS must be IPLed in order to detect the support.

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:
  • For System z10 systems at driver 73: MCL009 in EC stream (LPAR) F85901 (bundle 45b)
  • For System z10 systems at driver 76: MCL003 in EC stream (LPAR) N10965 (bundle 8).

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):
  • Sysplex timing capability is not required. However, to provide timing for all members of the sysplex, one of the following must be true:
    • The sysplex is a single-system sysplex on one processor.
    • The sysplex runs in multiple logical partitions on a single CPC.
    • The sysplex runs as a set of VM guests on the same VM image.
  • Unless your system is running in XCF-local mode, a sysplex couple data set is required.
  • If you have more than one system image in the sysplex, XCF signaling connectivity is required between each system in the sysplex.
In a sysplex configuration with two or more central processor complexes (CPCs), XCF requires all of the following:
  • Sysplex timing capability that extends to all of the processors that contain any of the z/OS or coupling facility images in the sysplex. The sysplex timing capability can be provided either of the following:
    • The Server Time Protocol (STP) feature of z13, Start of changez13sEnd of change, zEC12, zBC12, z196, z114, z10 EC, or z10 BC servers
    • A Sysplex Timer (9037), which is supported only in z10 EC and z10 BC servers.
  • Start of changeShared DASD for the sysplex couple data set. Certain functions require additional couple data sets. For more information, see z/OS MVS Setting Up a Sysplex.End of change
  • XCF signaling connectivity between each system in the sysplex and every other system in the sysplex.
    This signaling connectivity may be established using several different hardware means. The signaling mechanisms that are supported are:
    • FICON® or ESCON channels that are used as extended mode CTCs
    • Coupling facility channels connected to a coupling facility with the use of XCF signaling structures.

z/OS UNIX The extended user interface support allows existing hardware (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:
  • Real and emulated 3270s in a VTAM SNA network which satisfy the following.
    • The minimum screen size is 24x80.
    • The terminal must be known to TSO/E and VTAM as a full-screen device. z/OS UNIX services use full-screen mode.
    • The terminal must support uppercase and lowercase characters.
    • A minimum of 12 PF keys are required.
  • UNIX workstations and other workstations in a TCP/IP network that supports the TELNET 3270 (TN3270) client function.
  • The OMVS command supports customized PF keys to scroll backward/forward, display HELP, hide input typed into the command line, refresh the screen, retrieve previous commands, and enter TSO/E commands.
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:
  • Use of 3270 key sequences to emulate ASCII terminal control is supported.

    A set of system-defined 3270 default key sequences that map to ASCII escape control values is supplied. The user can tailor the system defaults.

  • Execution in canonical (line-oriented) mode only.
  • Conversion tables that map the 3270 data stream to a pseudoterminal device driver for both control and data are provided. Users can customize these tables.

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.
