SET MULTIBUS_FAILOVER
__________________________ Note _____________________________
Both controllers must be in
NOFAILOVER
mode before you use the
SET
MULTIBUS
_
FAILOVER
command.
____________________________________________________________
Places T
HIS
_
CONTROLLER
and the O
THER
_
CONTROLLER
into a dual-redundant (failover)
configuration in a multiple bus environment. This allows both controllers to access the
storage devices and provide greater throughput. If one of the controllers fails, the devices
and cache (if any) attached to the failed controller become available to and accessible
through the remaining operational controller.
__________________________ Note _____________________________
Partitioned storagesets and single-disk units cannot function in multiple bus
failover. You will have to delete your partitions before setting this switch.
____________________________________________________________
This command is intended for use with host systems that have two SCSI adapters, each
connected to one controller in the dual-redundant pair, show in Figure 2–1. The host
operating system must be configured to recognize that all units can be accessed through
either adapter/controller. If your host operating system does not support such a
configuration, use the
SET FAILOVER
command instead.
