Storage space and chunk configuration

The number of dbspaces, the number of chunks, their sizes, their path names, and their offsets must be identical on the primary and secondary database servers. In addition, the configuration must contain at least one temporary dbspace if the HDR secondary server is used for creating activity reports. See Use of temporary dbspaces for sorting and temporary tables.

UNIX™ Only:

You must use symbolic links for the chunk path names, as explained in Allocating raw disk space on UNIX.

Important: If you do not use symbolic links for chunk path names, you cannot easily change the path name of a chunk. For more information, see Renaming chunks.
