Knowledge Base “DSM/TC: How to adjust a FILECAT containing
CATALOGFILES for a missing system”.
A list of node names pairs (old value, new value) must be entered in the
configuration of catalog import at data store level. In all catalog import
processes for this data store, the node part of disk file name will be
adjusted in the inserted DISKFILE entries.
IMPORTANT NOTE: This file name change is likely to create confusion
in the catalog of backed files, if the target FILECAT for the replication
contains also the disk files backed up by the secondary system.
It is highly recommended to isolate in a separate FILECAT the entries
where the disk file names are modified by BackPak.
The BackPak configuration partially enforces this isolation on the system
running the Domain manager: if the node replacement in disk file name
is configured for the data store, no volume group in this data store can
direct the replicated DISKFILEs in a FILECAT that is also the default
FILECAT in MEDIACOM/MEDIADEFS.
Additional notes:
- VOLCAT is not involved by the change of disk file names. The change
of disk file names is not a reason to isolate a VOLCAT as target of
replication, although there is a general recommendation to isolate
the DSM/TC entries replicated by BackPak from the entries created
by BACKUP executed on the secondary local system; this isolation is
reached by creating dedicated VOLCAT and FILECAT to receive the
replicated entries.
- The user should carefully plan the consequences before changing the
node name in the disk file names of replicated DISKFILE entries.
