NSRMMD(8)NSRMMD(8)NAMEnsrmmd - NetWorker media multiplexor daemon
SYNOPSISnsrmmd [-v] [-s server] [-r system] -n number
The nsrmmd daemon is the storage node daemon and is responsible for
network save and recover media multiplexing operations.
The nsrmmd daemon does the following:
o Receives backup information from the NetWorker client.
o Writes data to the devices (volumes).
o Sends tracking information to the NetWorker server to track the data
written to the devices (volumes).
o Reads the data from the devices (volumes) at the request of the
client during a recovery.
The nsrmmd RPC program ID is 390104 and the daemon version number is 5.
To support multiple instances of nsrmmd (if the Concurrent Device Sup‐
port feature is enabled), the daemon numbers are incremented by 100.
The first daemon registered is 105, then 205, and so on.
One nsrmmd per enabled device is started automatically by nsrd. Addi‐
tional nsrmmd daemons can be started when a mount request is pending.
To change the number of daemons, alter the number of enabled devices.
Specify the daemon number.
Specify the controlling server. This option is used on a storage
node (see nsr_storage_node(5)).
Some nsrmmd programs run on the server but are controlling a
device attached to a Network Data Management Protocol (NDMP)
system. Such instances of nsrmmd have an optional -r argument
specifying the system that is being controlled.
-v Verbose: Print out messages about what the daemon is doing.
