Page 177: Chapter 16. Attaching To An Ibm San Volume Controller Host
Attaching to an IBM SAN Volume Controller host with fibre-channel adapters You can attach a storage unit to the IBM SAN Volume Controller host system using the SAN Volume Controller (SVC) fibre-channel adapter. Note: For a list of open-systems hosts, operating systems, adapters and switches that IBM supports, see the Interoperability Matrix at http://www.ibm.com/servers/storage/disk/ds6000/interop.html.
Page 178 v Select the WWPN from the list. To do this, you must have already zoned the SAN Volume Controller with a storage unit, and the SAN Volume Controller must be turned on. v Manually enter the WWPN for the host port. Note: A configuration command fails if you use a WWPN that equals zero (0).
Page 179: Chapter 17. Attaching An Sgi Host System
You can also connect a nonclustered SGI host system to the storage unit using the switched fabric topology on optical fiber media, SGI fibre-channel host bus adapters, and the IBM 2109 switch. You can also connect directly from an SGI host system to a storage unit with the arbitrated loop topology.

Page 185: Confirming The Availability Of Failover
IRIX multipathing does not perform dynamic load-balancing; it only provides path failover. You can achieve static load-balancing if you distribute the primary paths evenly across the controllers when you set up the failover groups in the /etc/failover.conf file. When a failover occurs to the alternate path, you must use the /sbin/scsifo -d command to manually return to the primary path.

This chapter tells you how to locate the WWPN value for a fibre-channel adapter on the following host systems: v Fujitsu PRIMEPOWER v Hewlett-Packard AlphaServer v Hewlett-Packard 9000 v IBM eServer iSeries v IBM eServer pSeries or RS/6000 v Linux v Novell NetWare v SGI (Silicon Graphics, Inc.) v Sun v Windows 2000...
Page 242: Locating The Wwpn For A Hewlett-Packard Alphaserver Host
Locating the WWPN for a Hewlett-Packard AlphaServer host This section provides instructions to locate the WWPN for a Hewlett-Packard AlphaServer host. 1. From the console prompt, type: P0>>>wwidmgr -show ada See Figure 85 for an example of what you see when you type the P0>>>wwidmgr -show command.
