Library Information Field
This is the section for Library Information. These records are
collected when SMSDATA is selected, and Libraries are defined in the
control data set selected. The record type for this record is 'LB'.
- Name
- Description
- DLBNMFLD
- The Optical or Tape Library name.
- DLBNMLEN
- The length of this construct name.
- DDLBLNAME
- The full field for the name.
- DLBNAME
- The eight character name of the Optical or Tape Library
- DLBDUSER
- The USERID of the last person to make a change to this construct.
- DLBDDATE
- The date that this construct was last changed. The format is "YYYY/MM/DD" in EBCDIC.
- DLBDTIME
- The time that this construct was last changed. The format is "HH:MM" in EBCDIC.
- DLBNSTAT (8)
- This field contains status information for the optical library
for all eight possible systems.
- DLBOMST
- This field contains the status information for each library.
- DLBSOUT
- The requested OAM status.
- 0
- No Connectivity

- Online

- Offline
- 3
- No Outstanding Request
- DLBCFCS
- The current OAM status.

- DLBTYPE
- Specifies the library type. This field contains either REAL or
PSEUDO. A real library is a physical library containing from 1 to
4 drives, while a pseudo library is a library consisting of stand-alone
drives only.
- 0
- Real Library
- 1
- Pseudo Library
- DLBDTYPE
- The library device type for this library
- 0
- The IBM® 9426 Library
- 1
- The IBM 3995 Library
- 2
- Tape Library
- DLBDCONS
- This field specifies the name of the MVS™ console that is associated with the library. Associating a console with a manual tape library allows MVS to direct messages for that library to its console. MVS continues to use the normal MVS routing code information for automated tape libraries and manual tape libraries with no specified console name.
- DLBEDVT
- This field specifies the default volume type for inserted tape
cartridges. A value of PRIVATE means the tape cartridge can only be
used by referencing its volume serial number. A value of SCRATCH means
you can use the tape cartridge to satisfy a non-specific volume request.
This field is mapped by the constants DLBPRVT and DLBSCRT.
- 1
- Private
- 2
- Scratch
- DLBEJD
- This field specifies the default action for the Tape Configuration
Data Base volume record when a tape cartridge is ejected from this
library. A value of PURGE means the volume record is deleted from
the Tape Configuration Data Base. A value of KEEP means the volume
record is not deleted from the Tape Configuration Data Base. This
field is mapped by the constants DLBPURGE and DLBKEEP.
- 1
- Purge TCDB Volume Record
- 2
- Keep TCDB Volume Record
- DLBLCBID
- This field specifies the EBCDIC representation of the five digit hexadecimal library sequence number returned by the tape control unit in response to a Read Device Characteristics command - the value placed in the library hardware at the time it was installed. The LIBRARY ID connects the library name to the library hardware.
- DLBEDUNM
- This field specifies the entry default unit name of the library.
- DLBDEFDC
- This field specifies the default data class for inserted tape cartridges. The data class name must identify a valid data class whose recording technology, media type and compaction parameters are used as the default values if the cartridge entry installation exit does not supply them. All other data class parameters are ignored.
- DLBDCLEN
- This field specifies the length of the data class name.
- DLBDCLNM
- This field contains the entire 32 characters for the data class name. Only eight characters are used in today's environment.
- DLBDCNAM
- This field contains the eight character data class name.
- DLBSTAT
- This field shows status by processor, and can have up to 32 system
status entries.
- DLBSYSST
- System status.
- DLBREQST
- Requested system status. Similar to DLBSOUT.
- DLBCURST
- Current system status. Similar to DLBCFCS.
