Issue/Introduction
SUMMARY:
While trying to run a restore you can get the following error messages:
ADSDM903 2433 AN SVC 99 ERROR HAS OCCURRED IN -- DYNAMIC ALLOCATION
ADSDM903 2433 ---------------------------------------------------------
ADSDM903 2433 S99R15RC => 4
ADSDM903 2433 S99ERRCD => 0218
ADSDM903 2433 S99INFCD => 0000
ADSDM903 2433 ---------------------------------------------------------
ADSDM903 2433 DSNAME=S06.SYSOUT3
ADSDM903 2433 VOLUME=MIGRAT .
ADSDM903 2433 UNIT=3390
ADSDM903 2433 THE VOLUME IS NOT MOUNTED AND MOUNT WAS NOT REQUESTED/AUTHORIZED.
This is because you have installed PTF RO69420 (GDG Phase II) and its associated corrective ptfs.
INSTRUCTIONS:
The GDG Phase II enhancement with MIGRAT support introduced a fundamental change:
Data set catalog entries are now kept in catalog during the archive and restore process. As a result, the CA Disk Catalog Management hooks are now required. Catalog volser problems can occur if the hooks are not installed. The Catalog Management hooks are installed by the command: S DMSAR
Prior to GDG Phase II, if a customer did not recatalog data sets for Auto-restore, nothing was catalogued to ARCIVE so the hooks were not absolutely required.
With GDG Phase II, CA Disk is keeping the existing catalog entry even for a real data set so it gets altered to MIGRAT and the physical data set deleted. It then restores the data set and alters it back to the new volume(s).
CA Disk is using MIGRAT behind the scenes and needs the hooks being installed to make sure CA Disk code gets ARCIVE (RECATVOL sysparm) value back – not MIGRAT.
The hooks are needed as gatekeeper so the system sees what it needs as CA Disk does.
Customers could leave RECATMIG at N but CA Disk still needs the catalog hooks.
ADDITIONAL INFORMATION:
Refer to the System Guide Chapter 6 for details on Sysparm RECATMIG, RECATVOL
As always, please contact CA Technologies support for CA Disk if you have further questions.
