■ For large configurations, begin drive sharing with a few tape drives and two
or three media servers (or NetBackup SAN media servers).
■ Configuration and troubleshooting processes are easier on smaller
configurations. If possible, create multiple and independent Shared Storage
Option configurations with subsets of servers sharing subsets of SAN-attached
drives.
■ Use the correct start order for your Fibre Channel hardware, as follows:
■ Robots or drives
■ Bridges
■ Hubs or switches
■ Hosts
■ The start sequence is longer for some devices than others. To verify that the
hardware starts completely, examine indicator lights. A green light often
indicates a completed start sequence.
About installing and configuring drivers
On the media server systems, install and configure drivers and modify the
appropriate system configuration files.
Guidance about the NetBackup requirements is available.
See the NetBackup Device Configuration Guide.
Verifying the connectivity
Test your hardware configuration before you configure Shared Storage Option
in NetBackup. This task is very important and is often overlooked.
Note the following points:
■ Verify that all of your servers (master and media) can communicate with one
another. To do so, use the ping command from each server to every other
server. Be sure to ping by host name to verify that the name resolution methods
function properly.
■ Use the NetBackup bpclntcmd utility to resolve IP addresses into host names.
For more information, see the NetBackup Troubleshooting Guide and the
NetBackup Commands Reference Guide.
■ Use operating system and NetBackup commands and tools to verify that the
devices are configured correctly. Make sure that the operating system detects
