Page 4: Overview
The HP iSCSI protocol transports block-level storage requests of TCP connections over IPv4 and IPv6. Using the iSCSI protocol, systems can connect to remote storage and use it as a physical disk although the remote storage provider or target may actually be providing virtual physical disks. HP Accelerated iSCSI supports all targets that are certified and supported by Linux software. - Page 5 HP NC532m Dual Port Flex-10 10GbE Multifunction BL-c Adapter • HP NC532i Dual Port 10GbE Multifunction BL-c Adapter* * Requires an HP ProLiant Accelerated iSCSI license to enable acceleration iSCSI targets. All iSCSI targets supported by the Linux software initiator are supported by HP. Overview 5...

Page 7: Installing The Linux Iscsi Offload Bnx2I Driver
Verify that the old netxtreme2 package has been removed as follows: # rpm -q netxtreme2 Verify if a old version of bnx2 or bnx2x is loaded into the kernel and remove it, if needed, as follows: If you are installing the package over the network, it is not necessary to remove the modules. This step is only necessary if you are doing the upgrade on the physical console and you want the new drivers to take over immediately. -
Page 8: Linux Iscsi Offload Bnx2I Driver Limitations
The current version of the driver has been tested on 2.6.x kernels beginning with the 2.6.18 kernel. The driver may not compile on kernels older than the 2.6.18 kernel. SLES10 SP1 is an exception. It also runs on the 2.6.16.46 kernel because SUSE upgraded the iscsi_transport kernel module to support offload initiators in SLES10 SP1. - Page 9 Most systems are set to level 6 by default. To include debug-level messages, set the level to 7. The following sample messages are the most common bnx2i driver messages that may be logged in the file /var/log/messages. • bnx2i driver signon Broadcom NetXtreme II iSCSI Driver bnx2i v1.0.30 (Sep 29, 2007)
