PRINT-CONFIGURATION Output system configuration

The user requests output of the system configuration using the PRINT-CONFIGURATION statement. The print appears after the first output of the monitoring environment. The first configuration which SM2R1 finds in the form of SM2 records in the first session to be analyzed is printed. This is an output of the configuration statistics. Modifications relating to dynamic I/O configuration change are output in a separate table (see section "Additional outputs").

Format

PRINT-CONFIGURATION

The configuration is output in hierarchical form. The hierarchical levels are formed by the channels (CHANNEL-PATH-ID), device controllers (CONTROLLER) and attached devices (ATTACHED DEVICES).

The following information is output in the headers for the individual levels:

1. CHANNEL-PATH-ID: nnnn channel-type

   where nnnn is the channel number in hexadecimal format and channel-type is the channel type (BUS CHANNEL, TYP FC).

2. CONTROLLER: mn

   where mn is the mnemonic controller name.

3. In the case of devices directly attached to the channel and on the same controller level, the following header appears:
   DIRECT ATTACHED DEVICES

   The header contains the same information as for the level which follows: This level further delineates the devices attached to a controller.
   The header is then:
   ATTACHED DEVICES

   The individual devices are then listed.

   Here “attached” implies use within the configuration. See also the DETACHED entry.

   The following entries appear under the header:

   DEVICE MNEM
   The mnemonic device name.

   VOLUME (VSN)
   Volume header, if any.

   PATH INFO
   Provides the input/output path, i.e. channel (4 characters) and device address (2 characters).

   DEVICE TYPE
   External designation of the device.

   INTERNAL CODE
   System-internal device code.

4. The following eight entries represent possible device attributes or information. If a device had the corresponding attribute at the time of monitoring, this is indicated by * in some columns. Otherwise, the corresponding information is output.

   DETACHED DEVICE
   The device exists within the system configuration, but it is not available at the present time (e.g. /DET UNIT=(mm,mn,...)).

   PAGING DEVICE
   The device is one used for paging.

   PRIVATE DEVICE
   Exclusive device assignment for a task. In the case of disks and tapes, marking takes place only if a volume has been mounted.

   SHARED PRIVATE
   Identifies a private disk which can function as a shareable private disk in MSCF mode (SHARED PRIVATE DISK).

   SYSTEM PRIVATE
   Identifies a private disk which can be used by multiple tasks.

   BLOCK FORMAT
   Identifies a disk’s block format (K2, NK2, NK4).

   PAV
   Identifies a basic device (B) or alias device (A); otherwise, spaces are output.

   BASE MNEM
   Specifies the mnemonic device name of the basic device if it is an alias device; otherwise, spaces are output.
