6 Configuring failover for HP StoreEver MSL6840 Tape
Libraries
The MSL6480 Tape Library supports both basic and advanced path failover, though basic and
advanced path failover cannot both be used in a partition at the same time. For example, advanced
data path failover can be used with advanced control path failover or without control path failover,
but not with basic control path failover.
Configuring control path failover
Control path failover is configured for each partition with the Expert Partition Wizard.
The requirements for using basic control path failover in a partition are:
•
Two LTO-5 or two LTO-6 Fibre Channel drives of the same type (Ultrium 6250 half height;
3000 half height or Ultrium 3280 full height) are in the partition. Additional tape drives may
be included in the partition but cannot be configured for failover.
•
Advanced and basic failover may not be mixed within a partition.
•
The Data Path Failover license has been added to the library.
The requirements for using advanced control path failover are:
•
Two LTO-6 Fibre Channel drives are in the partition. SAS and earlier generation tape drives
can be in the same partition, but cannot be configured for Advanced CPF.
•
Basic data path failover is not enabled for the partition. Advanced and basic failover may
not be mixed within a partition.
•
The Control Path Failover license has been added to the library.
Enabling control path failover
Control path failover is enabled with the Expert Partition Wizard. From the Configuration area,
click Expert Wizard in the Partitions menu to start the wizard. Select the type of failover for the
partition from the Select Control Path Failover Settings screen as shown in
Figure 6 (page 27) .

Figure 7 (page 28) shows the Select Control Path screen of the wizard. Select the active and passive
control path drives. In the example shown, drive 1 is set as the primary path and drive 2 is set as
the secondary path.
