Problem: When switching iSCSI boot from the Microsoft standard path to Broadcom iSCSI offload, the booting fails to
complete.
Solution: Install or upgrade the Broadcom Virtual Bus Device (VBD) driver to 5.0.x, along with the OIS driver, prior to
switching the iSCSI boot path.
Problem: The iSCSI configuration utility will not run.
Solution: Ensure that the iSCSI Boot firmware is installed in the NVRAM.
Problem: A system blue screen occurs when installing the Broadcom drivers through Windows Plug-and-Play (PnP).
Solution: Install the drivers through the Setup installer.
Problem: For static IP configuration when switching from Layer 2 iSCSI boot to Broadcom iSCSI HBA, then you will receive
an IP address conflict.
Solution: Change the IP address of the network property in the OS.
Problem: After configuring the iSCSI boot LUN to 255, a system blue screen appears when performing iSCSI boot.
Solution: Although Broadcom's iSCSI solution supports a LUN range from 0 to 255, the Microsoft iSCSI software initiator
does not support a LUN of 255. Configure a LUN value from 0 to 254.
Problem: NDIS miniports with Code 31 yellow-bang after L2 iSCSI boot install.
Solution: Run the T7.4 installer.
Problem: Unable to update inbox driver if a non-inbox hardware ID present.
Solution: Create a custom slipstream DVD image with supported drivers present on the install media.
Problem: In Windows Server 2012, toggling between iSCSI HBA offload mode and iSCSI software initiator boot can leave the
machine in a state where the HBA offload miniport bxois will not load.
Solution: Manually edit [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bxois\StartOverride] from 3 to 0.
Modify the registry key before toggling back from NDIS to HBA path in CCM.
NOTE: Microsoft recommends against this method. Toggling the boot path from NDIS to HBA or vice versa
after installation is completed is not recommended.
Problem: The Xen hypervisor will not start when booting from an iSCSI image created with the RHEL 5.4 Xen kernel.
Solution: This is a known third-party issue. To work around this issue, disable the Xen hypervisor's EDD feature by editing
the grub.conf file in the boot/grub folder to add the edd=off switch to the end of the kernel line. For example,
kernel /xen.gz edd=off
.
Problem: Unable to connect to an EqualLogic target using Windows Server 2008 and higher.
Solution: Add an exception to your firewall to allow ICMP echo requests.
Problem: Installing Windows onto an iSCSI target via iSCSI boot fails when connecting to a 1 Gbps switch port.
Solution: This is a limitation relating to adapters that use SFP+ as the physical connection. SFP+ defaults to 10 Gbps
operation and does not support autonegotiation.
