DSNP028I csect-name HSM RECALL FAILED FOR DSNAME = dsn HSMRC=rrrrrrrr,HSMRSN=ssssssss CONNECTION ID=xxxxxxxx, CORRELATION ID=yyyyyyyyyyyy, LUW-ID=logical-unit-of-work-id =token

Explanation

This message indicates that a required data set was migrated by HSM and an attempt to recall the data set failed, preventing Db2 from accessing the data set. The HSMRC and HSMRSN fields can be used to determine the HSM failure. See Problem Determination below. The connection ID, correlation ID, and 'logical-unit-of-work ID' (LUW-ID) identify the user or application that encountered the problem.

A LUW-ID of '*' indicates that the thread does not have a LUW-ID. If the LUW-ID is not an '*', the value is a 'logical-unit-of-work-id' that is assigned to the thread followed by an '=' sign and a token value, which can be used in place of 'logical-unit-of-work-id' in any Db2 command that accepts 'logical-unit-of-work-id' as input.

Messages that have the same connection ID, correlation ID, and LUW-ID relate to the same user. This makes it possible to scan a number of DSNP-prefixed messages and group activities involving a given user. Correlation IDs beginning with '0nn', where 'nn' is a number, identify system agents.

System action

DSM terminates its action with the associated data set. Higher level functions that issued the recall request might terminate.

Operator response

Notify the system programmer.

System programmer response

Investigate the reason for the HSM recall failure. Use the information in this message to help resolve this problem. Additional messages on the MVS operator's console might be associated with this message.

Problem determination

If the HSMRSN is 999, refer to the following list for the explanation:
HSMRC
Description
4
HSM is not active.
8
No storage is available for MWE in CSA.
36
Input MWE is not within user storage.
40
Allocated amount of CSA for MWEs was exceeded.
100
There was an invalid function used.

For all other reason codes (HSMRSN), refer to the DFSMShsm Managing Your Own Data for an explanation of HSM user messages. The HSM user messages can be determined by appending the value in the HSMRC field of this message to ARC1100I (that is, HSMRC=12, HSM message is ARC1112I). The HSMRSN reason code is referenced in the ARC1100I messages.
