Reason:
This message issues when DIF Support that ASR requested for data set dsn is not able to complete successfully. The component is displayed only for old VSAM data sets. A value of '?' indicates that it was not possible to determine the name.
Action:
One or more VAM0093x messages detailing the reason for the failure follow this message. Take appropriate action based on the detailed reason.
The following messages are the possible VAM0093x messages along with a summary of their meaning:
Volume Level DIF requires an associated VOLSER variable value.
Space reduction not possible due to zero available free space.
Permitted range of MINIMUM_PERCENT variable is 1 – 99.
Permitted range of REDUCE_BY variable is 1 – 99.
STORGRP variable value is not defined as an SG in active PLSSTRMB.
SMS_SUBPOOL_SG variable value is not defined as an SG in active PLSSTRMB.
VOLSER variable value is not a valid online DASD volume.
Specified REDUCE_BY value needs corresponding MINIMUM_PERCENT value.
Specified MINIMUM_PERCENT value needs corresponding REDUCE_BY value.
MINIMUM_PERCENT value did not allow for enough of a space reduction, or cannot reduce space amount below one (1) average record (AVR) unit.
DOES_IT_FIT=N. No values are specified for REDUCE_BY, MINIMUM_PERCENT.
SMS_SUBPOOL_SG only honored by DIF options when EXCLUDE_VOLS=Y.
Volume Level DIF in the ALLOC and DEFINE Environments only applies to SMS-Managed specific volume requests when GUARANTEED SPACE=Y.
Storage Group Level DIF in the EOV and EOV_VSAM Environments only applies when redirection has been requested.
Volume Level DIF in the ALLOC and DEFINE Environments does not apply to non-SMS-Managed that are redirected because a STORGRP has been specified for it.
Nonspecific requests with GUARANTEED SPACE=Y are not eligible for Volume Level DIF.
Some or all available free space in the Storage Group has already been reserved for deferred allocations.
SNA condition not possible due to requested TRKs or CYLs already zero.
KEYDSN match excluded one or more otherwise eligible volumes.
Volume Level DIF Support is not applicable because the target volume has no available free space.
DOES IT FIT Support is not applicable for zero space allocation requests.
None of the volumes in the dfSMS Storage Group are available for new space allocations.
Unexpected error encountered. Code xxxx provides information to Support.
Action:
If you feel that the message was issued in error, rerun the failing job with DIAGS=<jobname> tracing activated and forward the output to Technical Support.
Note: The default setting (N) for sysparm PLSOPT39 unconditionally issues the VAM0093 messages. Specifying a value of (Y) for sysparm PLSOPT39 only conditionally issues the VAM0093 messages when VDSDIAGS diagnostics have been activated. You can activate the diagnostics either explicitly by coding VDSDIAGS DD in the job step or implicitly by specifying DIAGS=<jobname> in the CA Allocate started task.
