HP StorageWorks Data Replication Manager HSG80 ACS Version 8.7P Configuration Guide (AA-RPHZF-TE, March 2004)

Getting Started
46 Data Replication Manager HSG80 ACS Version 8.7P Configuration Guide
Site, Host, and Solution Preparation
Before you start operating your disaster tolerant (DT) subsystem, you must:
■ Ensure that you have sufficient space to install and store the subsystems and have
adequate power and cooling resources
■ If you choose to use more than one rack, understand the proper methods for positioning
and joining subsystems
■ Have the proper devices installed
■ Verify that all of the storage components are in place
Host Bus Adapter Requirements
To run your DRM solution, you should have two host bus adapters (HBAs) installed on your
host system. For detailed information on this hardware, refer to the HBA’s user guide that
came with your adapter.
At this time, it is important to locate and record the World Wide Names (WWNs) of each
HBA. For the HBA at the target site, you can record the WWN in the worksheet provided in
Chapter 4, “Configuring a Standard Data Replication Manager Solution.” The initiator site
HBA WWNs can also be recorded in the worksheet in Figure 19 in Chapter 4. You must have
this number handy when you rename the host connections in Chapter 4.
Note: The World Wide Name can be found on the bottom of the HBA board. Look for a small bar
code label with an IEEE (Institute of Electrical and Electronics Engineers) precursor. A WWN
example is 1000-0000-C920-A5BA.
Setting Up the B-Series Fibre Channel Switches
The Fibre Channel switches must be in place before the DRM subsystems can be cabled and
configured. You need the following to install your Fibre Channel switches:
■ Power cord
■ 10Base-T cable with RJ-45 connector (to be connected to an Ethernet hub or switch)
■ Fixed IP address and subnet mask (one of each per switch)
The Ethernet cable and IP address are required to monitor and administer the Fibre Channel
switch. Configure the Ethernet IP address and the Ethernet IP subnet mask with the front panel
buttons of the Fibre Channel switch (16-port switches only).
For B-series (1 Gb) switches, keep the following in mind:
■ A single fabric can contain no more that 28 switches.
■ No more that 50% of the ports can be connected to intersite links (ISLs).
■ Each intersite link (ISL) can support a maximum of from 7 to 11 end devices (hosts,
controllers, and so on), depending on the host operating system and load.
For other switch families (C-series and M-series) see the HP StorageWorks SAN Design
Reference Guide for current fabric limits.
When the Ethernet IP settings are established, perform the following steps:
1. Ping the switch using the Ethernet IP address of the switch. If this is successful, you have
access to the switch.
