Configuring Boot From SAN Using iSCSI-Based Dell Storage Arrays
Page 35
Troubleshooting
If the iSCSI Boot BIOS fails to detect the iSCSI target, perform the following troubleshooting steps and
try to boot the system from iSCSI:
1. Try disabling the spanning tree protocol (if enabled) on the switch ports on which the iSCSI boot
NIC is configured. For information about disabling the spanning tree, see the documentation that
shipped with the switch.
2. Check for data entry errors in the iSCSI boot settings in Network adapter's configuration menu. The
configuration options must match the instructions provided. For more troubleshooting procedures,
see the iSCSI boot section in the Intel PRO Family of Adapters User's Guide or in the Broadcom
NetXtreme Family of Adapters User's Guide and under Network on the Dell Support website at
support.dell.com/manuals.
3. To eliminate switch problems, try connecting the initiator to the target directly using a standard
Ethernet cable. Do not use a cross-over cable.
4. During the operating system installation to the iSCSI LUN, if you receive the error message: Failed
to create a new partition on the selected unused space. [Error:
0x80042453], then the indication is that the initiator connection has been made to a controller
that does not own the LUN.
Configuration Worksheet
You can use the following worksheet to capture boot from iSCSI configuration information.
