Function

With the SHOW-DISK-DEFAULTS command, users can obtain information on the default values for the assignment of private disks. These values do not apply to private disks requested with USE=SPECIAL.
The following presettings are possible:

• Time of device assignment or release (ASSIGN-TIME)
  The following values can be set for ASSIGN-TIME:

  USER:	Default value; the time of assignment or release of the device corresponds to the time the user assigns or releases the private disk.
  OPERATOR:	If the private disk is mounted (online), the assignment is executed immediately. Otherwise, the assignment cannot be made until the disk is placed online.

• Permissible initial job allocation types SHARED or EXCLUSIVE (USER-ALLOCATION)The following values can be set for USER-ALLOCATION:

  NO:	permits no initial allocations.
  ALL:	permits SHARED and EXCLUSIVE initial allocations.
  EXCL(usive):	permits only EXCLUSIVE initial allocations.
  SHARE:	permits only SHARED initial allocations.

• Monitor of initial job allocations SHARED or EXCLUSIVE
  The following values can be set for OPERATOR-CONTROL:

  NO:	monitors no initial allocations.
  ALL:	SHARED and EXCLUSIVE initial allocations must be confirmed by the operator.
  EXCL(usive):	EXCLUSIVE initial allocations must be confirmed by the operator.
  SHARE:	SHARED initial allocations must be confirmed by the operator.

  The command supports structured output in S variables (see "Output in S variables").
