HP StoreEver MSL6480 Tape Library - Manual (Page 25)

Configuration requirements after enabling control path failure
Library configuration
If Secure Manager is enabled, hosts that have been granted access to the control path device must
be mapped to the first Fibre Channel port of the drive for basic control path failover and must be
granted access to both ports for advanced path failover.
SAN configuration
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 CP drives. For additional SAN requirements, see
“Preparing the switches and hosts for failover” (page 18) .
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.
