HP ProLiant Networking Software Release Notes

During the installation of a 32-bit Linux operating system, HP recommends setting bnx2x.num_queues=1
in the kernel command line when the system boots up from the installation media to install the OS. The
bnx2x.num_queues=1 setting avoids potential out-of-memory issues.
Multipath configuration
HP recommends following the guidelines in Native Linux Device-Mapper Multipath for HP Storage Disk
Arrays Reference Guide when configuring multipath on your Linux systems. For more information,
search Native Linux Device-Mapper Multipath for HP Storage Disk Arrays Reference Guide on the SPOCK
website (http://www.hp.com/storage/spock). Additionally for Broadcom CNAs, HP recommends
adjusting the fast_io_fail_tmo value in multipath.conf for each storage array to 25 and adding the line
“fast_io_fail_tmo 25” to any array that does not already have this value defined. The adjustment avoids
a race condition that can result in unexpected target and LUN loss.
Boot from SAN on RHEL 6
Certain RHEL 6 configurations might experience boot-time IO errors when configured to boot from SAN.
To avoid this potential problem, when the RHEL6 installer prompts for the initial reboot after
installation—instead of continuing—press Ctrl-Alt-F2 to enter a shell. Edit
/mnt/sysimage/boot/grub/menu.lst and place bnx2x.disable_tpa=1 into the default kernel command
line.
VMware installations: Configuring a Broadcom 10GbE CNA Adapter to enable FCoE
---------------------------------------------------
1) Enable FCoE hardware offload on the CNA:
A. Access the host machine via SSH.
B. Determine which ports are FCoE capable:
# esxcli fcoe nic list
The output looks something like the following example:
vmnic4
User Priority: 3
