The nas Commands
nas_rdf
Facilitates communication between two Celerra Network Servers. Its
primary use is to manage Celerra systems and define the
relationships needed for disaster recovery in a Symmetrix Remote
Data Facility (SRDF
®
) environment. It is also used to establish
communication between Celerra systems and define the relationships
needed for file system replication using Celerra Replicator or
TimeFinder/FS.
SYNPOSIS
nas_rdf
-init [<cel_name> <ip>]
| -activate
| -restore
DESCRIPTION nas_rdf establishes and manages relationships for Control Stations
and Data Movers that physically reside in separate Celerra cabinets.
For SRDF, nas_rdf initializes the Celerra Network Servers, activates a
failover to a destination Celerra, or restores a source Celerra.
Configuration details depend on the type of SRDF: active/passive or
active/active’ SRDF/S for synchronous replication with disaster
recovery, or active/passive SRDF/A for extended-distance,
asynchronous replication with a point-in-time replica.
Note: The apostrophe in active/active’ indicates that both sites have a source
volume mirrored at the other site.
SRDF is supported only on a Celerra Network Server attached to a
Symmetrix system. Also, this command must be run from a primary
Control Station in slot 0; it will report an error if run from a Control
Station in slot 1.
Note: This command must be executed from the /nas/sbin directory,
unless otherwise directed. Log in as nasadmin and su to root to execute this
functionality.
OPTIONS -init [<cel_name> <ip>]
Initializes a source or destination (target) Celerra Network Server for
SRDF/S or SRDF/A, or if <cel_name> and <ip> are specified, builds
the trust relationship between two Celerra Network Servers as part of
the initialization.
