LISTEDT subcommand — format the eligible device table (EDT)
Use the LISTEDT subcommand to display information from the eligible device table (EDT). You can access the EDT in a dump data set or in active storage.
The system can have two EDTs during a dynamic configuration change. You must distinguish between formatting a primary EDT and a secondary EDT.
Each EDT is divided into subtables, which you can format separately with LISTEDT.

-------- SETDEF-Defined Parameters -------------------------
Note: You can override the following SETDEF parameters.
See SETDEF subcommand — set defaults.[ ACTIVE | MAIN | STORAGE ] [ DSNAME(dsname) | DATASET(dsname) ] [ FILE(ddname) | DDNAME(ddname) ] [ PATH(path-name) ] [ FLAG(severity) ] [ PRINT | NOPRINT ] [ TERMINAL | NOTERMINAL ] [ TEST | NOTEST ]
- Parameters
- PRIMARY or SECONDARY
- Specifies the EDT that is to be formatted. The types of EDTs
are:
- Primary EDT: processes all current and new allocation requests.
- Secondary EDT: processes all allocation requests issued before a dynamic configuration change.
PRIMARY is the default. If you specify SECONDARY and no secondary EDT exists in the source storage or dump, IPCS displays message IEF10010I in the report.
- Data Selection Parameters
Use these parameters to limit the scope of the data in the report. If you omit a data selection parameter, the default is HEADER.
In the data selection parameter descriptions, index-number-list is one or more 1- to 4-digit hexadecimal numbers, ranges of numbers, or both. Each index number corresponds to an index for a sub-table entry. If you omit index-number-list, IPCS formats the entire sub-table.
The index-number-list can be a single number, a range of numbers, or a list of numbers. When you specify a range, separate the first and last numbers in the range with a colon. When you specify a list, separate the numbers with commas. The number or numbers are enclosed in parentheses.- COMPGENS
- Specifies that the compatible-generic section of the EDT appears in the output. Generics are compatible when a data set can be allocated to any generic.
- DETAIL
- Specifies that all the subtables in the EDT appear in the output.
- DEVNUM[(index-number-list)]
- Specifies that the device number section appears in the output.
- DEVPOOL[(index-number-list)]
- Specifies that the system-managed type library device pool entries in the EDT appear in the output. Each pool represents a set of tape drives within a library. In the output, look-up-value entry indexes refer to the output of the LUV parameter of the LISTEDT subcommand.
- GENERIC[(index-number-list)]
- Specifies that the generic section of the EDT appears in the output.
- GROUP[(index-number-list)]
- Specifies that the group section of the EDT appears in the output.
- GRPCONV[(index-number-list)]
- With Version 4.2.0 or a later release, specifies that the group mask conversion table appears in the output. This table exists only after a dynamic configuration change.
- GRPMSK[(index-number-list)]
- Specifies that the group mask table appears in the output.
- GRPPTR[(index-number-list)]
- Specifies that the group pointer table of the EDT appears in the output.
- HEADER
- Specifies that the EDT header appears in the output.
- LIBRARY[(index-number-list)]
- Specifies that the system-managed tape library entries in the EDT appear in the output. The entries include indexes for the related system-managed tape library device pool entries.
- LUV[(index-number-list)]
- Specifies that the look-up value section of the EDT appears in the output.
- PREF[(index-number-list)]
- Specifies that the preference table appears in the output.
- SHOWDEVN(device-number-list)
- Lists the group number to which each device number in the device-number-list belongs. device-number-list must be specified and should consist of one or more 1- to 4-digit hexadecimal device numbers, ranges of numbers, or both.
- SHOWGRPN[(group-number-list)]
- Lists the unit names associated with each of the group numbers in the group-number-list. The group-number-list is one or more 1- to 4-digit hexadecimal numbers, ranges of numbers, or both. If you do not supply group-number-list, IPCS formats information for all the device groups in the system.
- SUMMARY[(unit-name-list)] | SHOWUNIT[(unit-name-list)]
- Produces a summary report for all the unit names in the unit-name-list. The unit-name-list is one or more 1- to 8-character alphanumeric unit names. Separate multiple list items with one or more commas, blanks, or tab characters (X'05'). If you do not supply unit-name-list, IPCS formats information for all unit names in the system.
- TAPE
- Requests formatting of the tape maximum eligibility table. The output includes tape device information such as density and device type.
- Return Codes
See Standard subcommand return codes for a description of the return codes produced by the LISTEDT subcommand.
- Example: Display
information for device numbers 0001 through 0006 and 0021 through
0028 in the secondary EDT.
- Action
COMMAND ===> listedt secondary devnum(0001:0006,0021:0028)
- Result
See the allocation/unallocation component in z/OS MVS Diagnosis: Reference for an example of LISTEDT output.
