Configuring a Link Interface
Although the remote mirror software is most likely to be used with SunATM
link-level interfaces, the remote mirror software can be used with any link-level
interface supported by Sun that is TCP/IP-capable, such as Gigabit Ethernet, Gigabit
Ethernet Fibre Channel, and others.
When using ATM (Asynchronous Transfer Mode), ensure that the configuration
supports TCP/IP by using either Classical IP or LAN Emulation. For more
information on configuring the SunATM interface for these protocols, see the
SunATM documentation listed in “Related Documentation” on page xi. For more
information about other protocols, see the network protocol manuals also listed in
“Related Documentation” on page xi . Chapter 3 contains information about
configuring the Internet Protocol Version 6 (IPv6) transport protocol.
Before You Install the Software
Before you start the installation, you must make some decisions about your system
and you must prepare the system:
1. Determine your data replication requirements.
2. Determine if you are upgrading from a previous version. See Chapter 4 for
instructions on upgrading the software.
3. Choose the location of the Sun StorEdge configuration.
4. Set up the replicating TCP/IP network link for the remote mirror software. f
5. Allocate storage for the local and remote volumes and bitmap volumes for the
primary and secondary hosts for the remote mirror software.
6. Configure the shadow volume sets (consisting of master, shadow, and bitmap
volumes), if you are installing the point-in-time copy software.
7. Check the Sun StorEdge Availability Suite 3.2 Software Release Notes for latebreaking information.
