This section provides the information you need to prepare to install the subsystem device driver (SDD) for the Linux operating system on your pSeries™ host.
You must configure the storage unit for your host system and attach the required fibre-channel adapters before you can install the SDD.
Configure your storage unit for multiport access for each LUN before you install the SDD. To use the load balancing and path failover protection features, the SDD requires a minimum of two independent paths that share the same LUN. Failover protection is not provided with a single path. A host system with a single fibre-channel adapter connected through a switch to multiple storage unit ports is considered a multipath fibre-channel connection.
See IBM® System Storage™ DS6000™ Introduction and Planning Guide for more information about configuring the storage unit for the SDD.
You must configure the fibre-channel adapters and the adapter drivers that are attached to your host system before you can install the SDD. Follow the adapter configuration instructions to configure the adapters. See your Linux on pSeries documentation for details about installing the device driver on your fibre-channel adapter.
