Optional Features A.1.1 A.1.2 A.1.3 ICP RAID Controllers in a Cluster Configuration Due to required cable lengths (several meters) for the shared I/O channel(s) and the demands on transfer performance and quality, only Ultra160/320 SCSI and Fibre Channel controllers are suitable for clustering. Using such controllers allows for sufficient distances between the two servers and the RAID enclosure. For the successful installation and setup of clustering systems, note that computer systems, RAID Controllers, mass storage enclosures and accessories of suitable quality, such as cables, terminators, SCSI Bus Repeaters, and Isolators or Converters are all important. Hardware Installation SCSI channels which are used as a shared I/O bus require 2 SCSI Bus separators per shared channel to ensure that the shared channel will work even if a server is switched off, or if the bus is separated from the ICP RAID controller in one of the servers. Using ICP RAID Controllers with SCSI Interfaces Both ICP RAID controllers for the two nodes should be identical (same model, same firmware level). Before connecting both controllers to the shared I/O cable, one of the IOPs (In-put/Output Processor) on one of the controllers must be set to another SCSI ID for example, ID6. This should be done for all I/O channels which are used as Clustering channels. The easiest way to change the IOP IDs is to use ICPCON (ICP RAID Console) loaded with + from the controller's ROM. 196 Software Installation and User's Guide
