ARC0749I
CANNOT APPLY INCREMENTAL RECOVER TO VOLUME volser, REASON= reascode

Explanation

The RECOVER command was issued with the FROMDUMP and APPLYINCREMENTAL parameters. The volume requested to be restored has a valid dump copy, but DFSMShsm determined the application of incremental recoveries cannot be performed. Therefore, only the restore from the dump copy is performed.

The reascode value gives the reason the incremental recoveries could not be done. Valid values for reascode are:
Reascode
Meaning
4
A read error occurred reading a control data set record describing the source backup or dump information, or the record was not found. See message ARC0184I for the type and key of the record, and the type of error.
6
An error occurred in reading the JFCB while processing the backup VTOC copy data set.
8
A volume allocation error occurred.
10
Recovery of a more recent backup version of an OS CVOL failed. This recovery is attempted first. Since further processing may depend on the contents of this catalog, the process ends.
12
An error occurred in allocating the backup or dump VTOC copy data set.
14
An error occurred in reading the backup or dump VTOC copy data set.
15
Obtain of the format-1/format-8 DSCB of the VTOC copy data set failed.
16
An error occurred in opening the backup or dump VTOC copy data set.
18
The VTOC copy data set has a format-8 DSCB.
20
The required backup or dump tape volumes are not available.
22
The volume does not have both backup and dump VTOC copy data sets to use to build a list of candidate data sets for recovery.
24
An invalid or unsupported device type was found for the source backup, dump volume, or the migration level 1 volume where the VTOC copy data set resides, in its control data set record.
25
APPLYINCREMENTAL processing is not allowed because the volume contained a VSAM catalog the last time DFSMShsm dumped or backed up the volume.
26
APPLYINCREMENTAL processing is not allowed for DFSMShsm owned volumes because these volumes are not supported for the volume backup function.
27
APPLYINCREMENTAL processing is not allowed because the correct level of the Data Facility Product (DFP) is not installed on the system. The correct level of the DFP required to support this function is Release 2 Version 3 or subsequent releases, unless otherwise noted.
28
The MCV record that describes the volume on where the dump VTOC copy resides indicates that the volume is not a migration level 1 volume.
30
SMS has not been active in the system when DFSMShsm has attempted to process SMS-managed volumes.
32
DFSMShsm cannot determine if the volume being processed is an SMS-managed volume. The SMS volume definition and the volume VTOC entry do not agree.
34
An error has occurred while retrieving an SMS volume definition. DFSMShsm has invoked SMS to retrieve an SMS volume definition. SMS has failed to retrieve it.
52
A GETMAIN error occurred in getting storage for the recovery queue elements.
60
An error occurred in establishing an ESTAE environment.
66
An internal error occurred in sorting the queue of recovery queue elements (RQEs). The queue was broken.

System action

The restore process is performed. The incremental volume recovery is not performed. DFSMShsm processing continues.

Programmer response

If the volume contains an owning VSAM catalog, ensure that the catalog has been recovered with the latest backup copy and is in a usable state. DFSMShsm does not back up and recover VSAM catalogs. If the volume has been processed by volume backup, a volume recovery can be requested when the state of the catalog has been verified.

If the recovery of a catalog failed, determine if the catalog is usable and recent enough. If it is not, issue the RECOVER command for the catalog. If the catalog is usable or a later RECOVER command for the catalog succeeded, issue the RECOVER command for the volume again without the FROMDUMP and APPLYINCREMENTAL parameters and specify the date the volume was restored.

Use V1R12 or higher to recover volume if VTOC copy data set has a format-8 DSCB.
