Bug ID
Description
1948587
On RHEL 6 Update 5 Hosts, Host Drivers Cannot Load When Using a Standard initd/vmlinuz Image for PXE Boot
If you use the vmlinuz and initrd.img from the RHEL ISO, a problem prevents the vNICs and vHBAs from being accessible even though they are injected in to the custom boot image. Consequently, the RHEL 6 Update 5 host will not PXE or SAN Boot.
Workaround: For SAN or PXE Boot of RHEL 6 Update 5 hosts over an Oracle Fabric Interconnect, you must always use the vmlinuz and initrd.img from Oracle Linux instead of the Red Hat Enterprise Linux versions of these tools.

On RHEL 6 Update 5 hosts, SAN Booting Causes Kernel Panic When Accessing Boot Image
While creating a SAN boot image, an internal script inserts the Oracle Virtual Networking host drivers into initrd.img file instead of the initramfs.img that the REHL 6 Update 5 host expects. Although SAN install works correctly, when the server attempts to boot up, it experiences a kernel panic with an Init Not Tainted message.
Workaround: Run the following command after SAN install but before rebooting the server:
/sbin/mkinitrd -f --preload mlx4_ib --preload mlx4_core --preload xscore --preload xsvhba --preload xsvnic --with dm-multipath /boot/initramfs-2.6.32-431.el6.x86_64.img 2.6.32-431.el6.x86_64

During Reboot, an Oracle Linux 5 Update 10 Server With Multiple vNICs Experiences a Kernel Panic and Crashes
If you reboot an Oracle Linux 5 Update 10 host running 5.0.8 host drivers with two or more vNICs configured on it, the host will experience a kernel panic, then crash.
Workaround: Stop the openibd service before rebooting the server with two or more vNICs:
  1. Stop the xsigo service: service xsigo stop

  2. Stop the openibd service: service openibd stop

  3. Deactivate the openibd service so that it will not start again after server reboot: chkconfig openibd off

  4. Start the xsigo service: service xsigo start

Server Profile Staysup/down During PXE Boot on Oracle Linux
During a PXE boot image installation, the server profile on the Oracle Fabric Interconnect might stay in up/down state. After the host reboots and the host driver is loaded into memory, the server profile successfully comes online in an up/up state.
Workaround: No workaround exists at this time. The PXE installation is successful.

Seven-Second Multicast Traffic Hit When Subnet Manager Is Started
If an event causes a failover or restart of the OpenSM InfiniBand Subnet Manager, multicast traffic is delayed for approximately seven seconds while the failover or restart occurs.
Workaround: No workaround exists at this time.
