iSCSI configuration 2 - Software
Chapter 17.
Initiator on Red Hat Linux
This sample configuration shows how to connect logical drives configured on an IBM System
Storage DS3300 to a Red Hat Enterprise Linux 4 update 5 operating system running on an
IBM BladeCenter HS21 with included OpeniSCSI software initiator.
The Blade server has an Ethernet daughter card installed in the slot that connects to module
bays 3 and 4 of the BladeCenter chassis. The decision to use module bays 3 and 4 was made
to have dedicated network equipment for the iSCSI traffic. That increases network stability
and provides a safer SCSI connection later to the host.
Nortel Layer 2/3 Gigabit Ethernet switches are installed in module bays 1, 3 and 4. Bay one,
that connects to the first onboard NIC of the blades, is used for the public network access.
Bay 3 and 4 that connects to an expansion slot on the blade server are used to connect to the
installed gigabit Ethernet daughter card.
Its assumed that the DS3300 is set up with IP addresses, as described in 12.2.3, "Configure
iSCSI Host Ports" on page 276 and is ready to have the logical drives and host mapping
configured.
Note: DS3300 iSCSI connections are not supported from Red Hat Enterprise Linux 5 at
the time of writing. SuSE Enterprise Linux 10 is only supported with the iSCSI hardware
initiator and without Service Pack1. XEN kernels are not supported.
