Troubleshooting Known issues Known issues for Microsoft iSCSI Initiator boot installation • If you do not select an Adapter Service Name by highlighting it during initial Microsoft Initiator b oot setup, the setup continues without an error but does not select an NDIS driver for booting. The deployed system will display a stop error or Blue Screen of Death (BSoD) on boot prior to the first splash screen. • Multipath I/O (MPIO) is not supported for failover for boot filesystem because MPIO drivers cannot be added during an install phase. MPIO can be used on devices created later. • The iSCSI host name is derived from the InitiatorName that is set by the HP iSCSI BIOS and should not be used in the GUI. Known issues for F6 installation The HP Windows_F6 Diskette 1 must not be inserted in the A:\ drive until after F6 prompts for the diskette. Failure to wait for the prompt will cause the F6 installer to fail reading the second diskette. Using a diagnostic monitor for troubleshooting If the client is not able to b oot f rom the target server and the problem is not discernable from the immediately available information, you ma y need to use a network monitor that is capable of parsing the iSCSI protocol to troubleshoot the information. If the iSCSI target is software running on a server, you may be able to run a softwa re network monitor such as Ethereal directly on the ta rget system. Otherwise, you may need to configure a network switch with port mirroring and direct the mirrored packets to a port where either a hardware or softwa re network monitor can be attached. Target connection problems Symptoms: The initiator is unable to make a connection to the target. Possible causes: • The initiator and target are not connected to the same network • The initiator and target are not in the same VLAN (if any) • The IP configurations for the initiator and target are not correct • The initiator's boot path information is not correct • The target service is not running on the target server Troubleshooting 20
