Problem Solution
1 ServerEngines iSCSI BIOS
banner is not displayed
during system post Go to your motherboard BIOS configuration and make sure that Option
ROM is enabled is set for the PCI-E slot into which the BladeEngine 2
board is inserted.
2 Unable to Ping iSCSI target
IP address • Check cable connections and make sure they are securely connected
at both ends. Make sure the link light is on at both ends of the cable.
• Verify that you have assigned a valid IP address with the correct
subnet mask to the interfaces that are connected to the network.
• Check for Duplicate IP addresses.
• If the IP address is coming from DHCP, check that the DHCP server is
up and available.
• Is the target on a different subnet? Check the default gateway and
make sure that the IP addresses of both the default gateway and the
remote host are correct.
• Check link status under Network Configuration. If you try changing the
initiator link status, you can back out one screen then go back to
Network Configuration to see updated view of your current link status.
3 Login to iSCSI target fails or
Login succeeds but no LUNs
are available. • Check initiator IQN name and target IQN name. Verify that they are
properly specified.
• Check target’s ACL settings (if any) to verify that the initiator’s IQN
name is listed and can be recognized.
• Make sure that the target login parameters are compatible with the
initiator’s parameters.
4 Login to iSCSI target is
successful, but iSCSI I/O
causes the system to hang
or freeze. Check the jumbo frame settings on the iSCSI target. If enabled, change
the frame size to 1514 and retry. This isolates any problems in the
network related to jumbo frames. Jumbo frames, when supported by the
entire network, provide increased performance.
5 You are unable to boot
from your iSCSI target • Check the target setup, check Target ACL to verify that the initiator’s
iSCSI name is listed and can be recognized.
• Check Initiator name and make sure it is correct.
• If applicable, verify that you have selected the iSCSI LUN as the boot
LUN in your system BIOS setting.
• Check the system BIOS for boot device priority order.
• Make sure that the ServerEngines boot device is at the top (SE-
xxxxxx).
If using DHCP:
• If Boot Support is not enabled, enable it on the iSCSI Initiator menu.
• If DHCP boot support is enabled, check the DHCP setup and also
verify that you have added the root path to the DHCP server. For more
information see Target Discovery Through DHCP.
6 BIOS post displays “BIOS
Not Installed” message • If you have not configured an iSCSI boot target, this is proper normal
behavior.
• If you have configured an iSCSI boot target and the BIOS cannot find
