NSRMMDBD(8) Legato NetWorker 4.0 NSRMMDBD(8)
NAME
nsrmmdbd - NetWorker media (volume) management database daemon
SYNOPSIS
nsrmmdbd
DESCRIPTION
The nsrmmdbd daemon provides an RPC-based database service to the
local nsrd(8) and nsrmmd(8) daemons, and query-only network access to
NetWorker clients. The RPC program number provided by nsrmmdbd is
390107. The RPC version numbers provided by nsrmmdbd are 3, 4, and
5. Nsrmmdbd is normally started by nsrd(8).
The daemon manages a ``media and save set database'' located in the
file /nsr/mm/mmvolume. The primary purpose of the database is to
remember which save sets reside on which backup volumes. Numerous
access methods are provided to both save set and volume records
within the database.
FILES
/nsr/mm/mmvolume
File containing the volume data base.
/nsr/mm/.noscav
The existence of this file indicates that the indexing to
the data structures inside /nsr/mm/mmvolume need not be
rebuilt when nsrmmdbd is restarted. To forcibly rebuild
the indexes, remove this file when nsrmmdbd is not run
ning.
/nsr/mm/mmvolume.s
This temporary file is created to hold the media database
information that will be saved to tape by nsrmmdbasm(8).
/nsr/mm/mmvolume.r
A named pipe (created by nsrmmdbasm) that is read when
the media database information is being recovered.

DIAGNOSTICS
All diagnostic messages are posted as events and can be monitored in
a NetWorker console window.
media db is converting the old data, this may take a while
Any media databases created prior to the NetWorker 4.0 release
have to be converted (once) to the new database format. Plan
on allowing one second for every 100 save sets.
media db is converting %d volumes
This is printed after the volumes' data has been dumped from
the old database, but before it has been loaded into the new
database.

media db is converting %d save sets
This is printed after the save sets' data has been dumped from
the old database, but before it has been loaded into the new
database.
media db rebuilding save sets by %s
Printed for each of the various access methods to the save
sets' records. The methods include save set id, save time,
continuation save set, and save set name.
media db rebuilding volumes by %s
Printed for each of the various access methods to the volumes'
records. The methods include volume id, volume name, volume
type, volume pool, and bar code label.
media db is saving its data, this may take a while
Printed when the daemon is dumping its records to a temporary
file when the database is being backed up. The service is
unavailable while the database is dumping.
media db is recovering, this may take a while
Printed when the daemon is reloading its database. The ser
vice is unavailable while the data is being reloaded.
media db is recovering old data, this may take a while
Similar to the previous message, except that a pre-4.0
database is being recovered and it will have to be converted
before service resumes.
media db is cross checking the save sets
Printed each time the daemon is restarted. Upon start-up, the
daemon sanity checks its records before providing its service.
media db is open for business
Printed after any of the previous messages are printed to
indicate that the service is once again available.
