ZDMFS-Display Module File Status

Use this command to display the module file status table (MFST) information for one or more direct access storage devices (DASDs) assigned to the basic subsystem (BSS) or to a subsystem in a multiple database function (MDBF) environment.

Note:
In some places, a DASD is also referred to as a module.

Requirements and Restrictions

None.

Format




module
is a 1- to 3-digit hexadecimal symbolic input module number for real-time DASD or general data sets, or a pseudo module number for general file DASD.
Note:
If you do not specify a module number, information about the lowest module number is displayed.

number
is the number of DASD to be displayed from 0-18.

Online
displays information about the online DASD.

Additional Information

None.

Examples

The following information is displayed in the example:

 MOD 
is the symbolic or pseudo module number.

 TYPE 
is the DASD model number and one of the following indicators:

 ECKD 
Module is running in extended count key data mode.

 C/D 
Module is running in count key data mode on a caching control unit.

 C/E 
Module is running in extended count key data mode on a caching control unit.

 RCS 
Module is running in extended count key data mode on a full function record caching control unit.

 SDA 
is the symbolic device address.

 USE 
is the way the module is being used, where:

 GEN 
Module is a pseudo general file.

 RLT 
Module is a real-time file.

 GDS 
Module is a general data set.

 NMT 
Module is not mounted.

 DUP 
is the symbolic module number of the duplicate module, if one exists.

 STAT 
is the module status. The possible conditions are:

 ON 
Module is online.

 OFF 
Module is offline.

 COPY 
Module is being copied from or is being copied to by the ZMCPY function.

 VSN 
is the volume serial number.

 LOCK 
is the lock status, where:

 CF 
Module is running on a coupling facility.

 CFLF 
Module is running on a concurrency filter lock facility.

 LLF 
Module is running on a limited lock facility.

 NONE 
Module currently has no locking.

 COR 
is the correctable error count (in decimal).

 UNC 
is the uncorrectable error count (in decimal).

 PREFIX 
indicates one of the following:

 YES 
Module is running on a control unit that supports the prefixing architecture.

 NO 
Module is running on a control unit that does not support the prefixing architecture.

The following example displays the MFST information for six modules (00A - 00F).
