IBM SAN File System host attachment

This section describes the requirements that you need to verify before you to attach an IBM SAN File System metadata server to a DS6000™ with fibre-channel adapters.

Before you attach a host, review the following information:

The General requirements for attaching a host system
The Interoperability Matrix at http://www.ibm.com/servers/storage/disk/ds6000/ for the most current information and details for hosts, operating systems, adapters, and switches
Support for the IBM SAN File System, at http://www-03.ibm.com/servers/storage/software/virtualization/sfs/index.html
A list of supported host bus adapters (HBAs), firmware, and device driver information for your host system and host adapter at http://www-03.ibm.com/servers/storage/support/config/hba/index.wss

Notes:

You can attach a storage unit to the IBM SAN File System metadata engine using the SAN File System fibre-channel adapter. You cannot attach a storage unit to an IBM SAN File System host system using SCSI adapters.
You must create a host entry for each port on every SAN File System metadata engine in the cluster. For example, a four-node SAN File System cluster requires 8 host entries. See the steps in Host I/O port configuration through the DS Storage Manager for information on defining hosts and hosts ports.
