StorageTek 6 manual Defining LMU Network Connections, Defining Tape Request Attributes TAPEREQ

(UNITDEF) Command and Control Statement” on page 140 for control statement syntax, parameter information, and example statements.

Volume Attribute

The VOLATTR control statement specifies tape volume attributes. Refer to “Volume Attribute (VOLATTR) Control Statement” on page 143 for control statement syntax, parameter information, and example statements.

Volume Attribute Definition

The VOLDEF command and control statement identifies the definition data set where the tape volume attributes can be found (see VOLATTR). VOLDEF can be issued either in PARMLIB or as an operator command. Refer to “Volume Attribute Definition (VOLDEF) Command and Control Statement” on page 154 for control statement syntax, parameter information, and example statements.

Defining LMU Network Connections

LMUPATH statements allow users to define LMU network TCP/IP attachments. Network addresses can be specified by host name or LMU IP address.

Defining Tape Request Attributes (TAPEREQ)

TAPEREQ statements describe the media type and recording technique to be used for a particular data set.

TAPEREQ parameters are divided into selection criteria (inputs) and result criteria (outputs). Selection criteria include:

•job name

•step name

•program name (MVS JES2 only)

•data set name

•expiration date or retention period (MVS JES2 only)

•volume type requested (specific or nonspecific).

Result criteria include:

•media type

•recording technique

•model

•subpool.

Collections of data sets with common characteristics can be identified in a single TAPEREQ statement by specifying wild card characters. For example, if all data sets residing on ECARTs are identified with an ‘‘L’’ as the first character of the data set name, an ‘‘L**’’ could be specified to identify all these data sets in a single TAPEREQ statement.

The TREQDEF command causes the HSC to open the definition data set containing the TAPEREQ statements. See “Tape Request Definition (TREQDEF) Command and Control Statement” on page 133 and “Tape Request (TAPEREQ) Control Statement” on page 118 for descriptions of syntax and parameters.
