SAN configuration requirements
When basic control path failover is enabled, the library is no longer presented as a logical unit behind the
tape drive and is assigned a new Fibre Channel node name which needs to be zoned in the same zone
as the primary and secondary control path drives. For additional SAN requirements, see
switches and hosts for failover
on page 16.
After configuring the basic control path failover parameters, you might need to make additional changes:
• To find the world-wide name assigned to the library controller, use the
Monitor
>
Partitions
menu to
see the
Partitions Status
dialog. The world-wide name for the library controller is shown in the LCP
WWPN column.
• Hosts connecting to the library may need to be rebooted if the operating system does not support
dynamic device detection.
• Applications on hosts may need to be reconfigured to recognize the new library world-wide name.
