| - | === No "IscsiBP" messages appear === | + | ====== Common problems ====== |
| - | If you do not see any IscsiBP messages appear, then you do not have the boot-capable iSCSI initiator installed on the iSCSI-booting machine. | + | {{ :screenshots:win2k3_iscsi_install.png?400x300|Installing the Microsoft iSCSI initiator}} |
| - | * Did you download the boot-capable Microsoft iSCSI initiator from [[http://connect.microsoft.com]]? If you installed the standard Microsoft iSCSI initiator, then you will not be able to boot via iSCSI? | + | * Did you download and install the special boot-capable Microsoft iSCSI initiator as documented in [[:sanboot:winnt_iscsi|Adding iSCSI boot support to Microsoft Windows]]? If you installed the standard (non-boot-capable) Microsoft iSCSI initiator, then you will not be able to boot via iSCSI. |
| * Did you install the checked build (the file ending in //-x86chk.exe//)? If you installed the free build (the file ending in //-x86fre.exe//, then you may not see any diagnostic messages. | * Did you install the checked build (the file ending in //-x86chk.exe//)? If you installed the free build (the file ending in //-x86fre.exe//, then you may not see any diagnostic messages. | ||
| - | * When you installed the boot-capable Microsoft iSCSI initiator, did you tick the option to "Configure iSCSI Network Boot Support"? | + | * When you installed the boot-capable Microsoft iSCSI initiator, did you tick the option to "Configure iSCSI Network Boot Support" and select the correct network card to be used for iSCSI boot? ((This option is not available on Windows XP; you will need to also download and install [[:sanboot:winnt_sanbootconf|sanbootconf]] in order to boot via iSCSI.)) |
| - | === "IscsiBP Found device" message does not appear === | + | * If you are using Windows XP, did you download and install [[:sanboot:winnt_sanbootconf|sanbootconf]] in addition to the boot-capable Microsoft iSCSI initiator? |
| - | If you do not see a message starting with "IscsiBP Found device", then your network card is not being detected at boot time. | + | * If you are using iSCSI CHAP authentication, are all passwords at least 12 characters long? (The Microsoft iSCSI initiator will refuse to attempt authentication with shorter passwords.) |
| - | * When you installed the boot-capable Microsoft iSCSI initiator, did you select the correct network card to be used for iSCSI boot? | + | * Norton Internet Security's (at least 2009 and 2010) firewall is known to cause boot-time problems on XP. Disable the firewall before transferring your disk image to the iSCSI server. |
| - | === Other problems === | + | ===== VMware-specific problems ===== |
| - | You can e-mail the saved debugging transcript to <etherboot-discuss@lists.sourceforge.net>, along with any other information that you think may be relevant. Please note that the debugging transcript is the most important information; if you provide a full description of your setup and your problem, but do not provide the debugging transcript, then we will probably not be able to solve your problem. | + | VMware has a nasty habit of changing the PCI bus:dev.fn number assigned to the virtual NIC, which breaks the Windows driver bindings and so prevents a successful iSCSI boot. In most cases, you should ensure that the ''.vmx'' file for the VM that you are attempting to boot via iSCSI contains |
| + | |||
| + | scsi0.present = "TRUE" | ||
| + | |||
| + | even though there is no local hard disk attached.((VMware seems to assign PCI bus:dev.fn numbers dynamically. If you have a hard disk and a NIC in your virtual machine then VMware will typically assign the hard disk controller as PCI device 00:10.0 and the NIC as PCI device 00:11.0. You perform the Windows installation within the virtual machine then detach the hard disk, transfer the contents of the virtual hard disk to your iSCSI target, and try to boot from it. VMware will now reassign the NIC as PCI device 00:10.0, which will prevent Windows from enumerating the NIC correctly. By setting | ||
| + | |||
| + | scsi0.present="TRUE" | ||
| + | |||
| + | you can force VMware to create a hard disk controller (with no disks attached) as PCI device 00:10.0 and so reassign the NIC as PCI device 00:11.0, which is where Windows expects to find it.)) | ||
