SWCC Agent in TruCluster Environment
241HSG80 ACS Solution Software V8.8 for Tru64 UNIX Installation and Configuration Guide
■ Configure the SWCC client to use a cluster alias as the address for the SWCC
agent system to avoid having to change the client if the CAA swcc resource
fails over to another member. You can use the default cluster alias, or any
alias to which all of the cluster members belong.
Configure the Controller
The Hardware Configuration manual describes how to configure the hardware in a
TruCluster Server environment. This manual includes complete information on
setting up a controller in a shared SCSI or Fibre Channel environment. If
applicable to your environment, complete the tasks described in the Using Fibre
Channel Storage chapter. That chapter explains the use of Fibre Channel switches
and hubs, zoning switches and selective storage presentation (SSP). It also
describes example Fibre Channel configurations supported by TruCluster Server.
Use the Hardware Configuration manual to configure your hardware before you
implement this appendix. Although you perform some hardware configuration in
this appendix, do so after your initial hardware configuration is complete.
Use Multiple-Bus Failover Mode
In multiple-bus failover mode, all unit numbers (0 through 199) are potentially
visible on all four controller ports in a dual-redundant configuration. With
multiple-bus failover:
■ The host controls the failover by accessing units over a different path or
causing the access to the unit to be through the other controller.
■ An active controller causes a failover to the other controller if the controller
recognizes the loss of the switch, hub, or cable to a controller port.
■ Each cluster member system can have two or more (fabric only) KGPSA host
bus adapters (multiple paths to the storage units).
You set multiple-bus failover from the controller maintenance terminal with the
set multibus copy = this|other command. Ensure that you copy the configuration
information from the controller that you know has a good array configuration.
