2. Define the fibre-channel host system with the worldwide port name identifiers.
For the list of worldwide port names, see “Locating the worldwide port name
(WWPN),” on page 211.
3. Define the fibre-port configuration if you did not do it when you installed the
storage unit or fibre-channel adapters.
4. Configure the host system for the storage unit by using the instructions in your
host system publications.
A single SN5420 provides a 100 Mbps connection to a storage area network. You
can define up to four SCSI routers for the SN5420. You can have up to thirty-two
hosts on each SCSI router. Each host can have up to eight storage targets. Each
target can present multiple LUNS. For example, you can define eight LUNS for
Windows 2000 or Windows 2003. You can define thirty-two LUNs for the UNIX
operating system or the Linux operating system. A Windows iSCSI host can
discover sixty-four storage devices or eight targets times eight LUNs. A UNIX or
Linux host can discover 256 Storage devices or eight targets times thirty-two LUNs.
Ethernet adapter attachment considerations for the iSCSI Gateway
host
This topic provides Ethernet adapter attachment considerations for the iSCSI
Gateway host.
The iSCSI software driver resides on each host (initiator) and completes the
connection to a storage device (target). You can only use the iSCSI software drivers
(initiators) for the following host systems:
v Windows 2000
v Windows 2003
v Linux (Red Hat Enterprise Linux Server 2.1 and above)
The iSCSI protocol is based on TCP/IP. The iSCSI protocol depends on TCP/IP
addressing to identify the SCSI router lists and storage targets. You must install an
Ethernet adapter Network Interface Card (NIC) in the host computer.
You can connect NICs of 10/100 or 10/100/1000 through CAT5 copper or fibre
connector cables.
Note: For a list of open-systems hosts, the operating systems, adapters and
switches that IBM supports, see the Interoperability Matrix at
http://www.ibm.com/servers/storage/disk/ds6000/interop.html.
Configuring for storage for the iSCSI Gateway host
This topic provides information for configuring storage for the iSCSI Gateway host.
You must configure the storage unit to present storage LUNs to the storage router.
You must configure the storage router to list the storage LUNs in the SCSI router
definition. You must assign a TCP/IP address to the SCSI router. You must identify
an entry in the access list table for the storage router for each host. You can group
hosts that are listed in the access list table by operating system. The iSCSI
software driver must have the TCP/IP address that points to the scsirouter target,
and the list of storage LUNs defined in the scsirouter entry.
