RDF System Management Manual for H-Series RVUs (RDF 1.8)

NOTE: A single updater process only works on 500 files at any time. If you have a virtual disk
that has many physical disks in its pool, and if the number of files that need to be updated by
the updater assigned to that virtual disk exceeds 500, the updater will close some files in order
to work on files it does not already have open. If this updater must regularly work on more than
500 files, the performance of the updater is impacted. For optimal updater performance, ensure
that no single updater must work on more than 500 files on a regular basis. This condition might
mean that you have to reduce the number of physical disks in a pool.
RDF replicates Enscribe file creations when audited Enscribe files are created on RDF protected
volumes. When the UPDATEVOLUME is a virtual disk, the updater process tells SMF to create
the file and register it in the SMF catalog. When the UPDATEVOLUME is a virtual disk consisting
of multiple physical disks, SMF decides which physical disk will store the file. You have no
control over where a new Enscribe file is created. For more information about the factors SMF
uses to decide on the file placement, see the Storage Management Foundation User's Guide .
You can change the physical volume on which files reside in the SMF pool using the FUP
RELOCATE command. This command only works on closed files, so the updaters must be
stopped before relocating any files.
SMF allows physical disks to be added and removed from pools. The RDF updaters must be
stopped prior to the addition or deletion of any physical disks from SMF pools on the backup
system.
