When you specify your sanboot string, you have to include a LUN. It *may* be possible to attach more than one iSCSI target if you use keep-san and a second sanboot command. I assume you would also need to tell gPXE to connect the second iSCSI device as BIOS drive 0x81, which is a configuration setting you can give as a DHCP encapsulated option, but should be able to be set from the command line.</div><div><br></div><div>I don't have any idea whether or not it would work though, but I have to admit I'm curious now though ;-)</div><div><br></div><div>-Andrew Bobulsky</div><div><br></div><div><div><div>On May 26, 2010, at 6:03 AM, KernSafe Technology wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="hmmessage" style="font-size: 10pt; font-family: Verdana; ">Hi Andrew Bobulsky,<br> <br>>if you were to put an iSCSI HDD on LUN 0 and an iSCSI ODD on LUN 1, you'd still need to specify a second iSCSI connection<span class="Apple-converted-space"> </span><br> <br>I don't think it need a second iSCSI connection if you put more than one LUNs to one target, most of popular iscsi initiators suppport multiple-lun feature, all the luns use only one connection.<br>I think at least two things we need to do:<br>1, Modify int13 interrupt in gpxe and make it support CD-ROM.<br>2, Make target support multiple-lun.<br> <br>Windows setup will start to boot from gpxe (A iSCSI target with hold a CD-ROM and a harddisk is already descried by ibft), and then press F6 to install a third-party iSCSI drivers.<br>The iSCSI drivers will prepare two devices for windows (a hard drive and a CD-ROM).<br> <br>>By the way, is your target OS here XP/2003 setup?<br>Yes, I only consider windows at this time.<br> <br>KernSafe Technology<br>Windows iSCSI SAN provider,<br><font color="#0066cc"><font color="#0066cc"><font color="#0066cc"><font color="#0066cc"><font color="#0066cc"><font color="#0066cc"><font color="#0066cc"><a href="http://www.kernsafe.com/" target="_blank"><font color="#0066cc">www.kernsafe.com</font></a></font></font></font></font></font></font></font><br> <br><hr id="stopSpelling">Subject: Re: [gPXE] Will gPXE support booting from iscsi cd-rom?<br>From:<span class="Apple-converted-space"> </span><a href="mailto:rulerof@gmail.com">rulerof@gmail.com</a><br>Date: Tue, 25 May 2010 16:07:12 -0400<br>CC:<span class="Apple-converted-space"> </span><a href="mailto:gpxe@etherboot.org">gpxe@etherboot.org</a><br>To:<span class="Apple-converted-space"> </span><a href="mailto:kernsafe@hotmail.com">kernsafe@hotmail.com</a><br><br>Aldrich,<div><br></div><div>While I read that and though it might be a clever solution, the string that you pass to the sanboot command includes the LUN you want to connect the int13 device to, which defaults to LUN 0.</div><div><br></div><div>So, if you were to put an iSCSI HDD on LUN 0 and an iSCSI ODD on LUN 1, you'd still need to specify a second iSCSI connection :-(</div><div><br></div><div>By the way, is your target OS here XP/2003 setup?</div><div><br></div><div>-Andrew Bobulsky</div><div><br><div><div>On May 24, 2010, at 10:15 PM, KernSafe Technology wrote:</div><br class="ecxApple-interchange-newline"><blockquote><span class="ecxApple-style-span" style="text-transform: none; text-indent: 0px; border-collapse: separate; font: normal normal normal medium/normal Helvetica; white-space: normal; letter-spacing: normal; word-spacing: 0px; "><div class="ecxhmmessage" style="font-family: Verdana; font-size: 10pt; ">Hi Shao Miller,<br> <br>If it is reachable (modify int13), we can input a hard disk and a CD-ROM into one Target (multiple-LUN), so the workstation will get two SCSI devices from iBFT.<br><br> <br>> Subject: RE: [gPXE] Will gPXE support booting from iscsi cd-rom?<br>> Date: Mon, 24 May 2010 12:13:55 -0400<br>> From:<span class="ecxApple-converted-space"> </span><a href="mailto:Shao.Miller@yrdsb.edu.on.ca">Shao.Miller@yrdsb.edu.on.ca</a><br>> To:<span class="ecxApple-converted-space"> </span><a href="mailto:kernsafe@hotmail.com">kernsafe@hotmail.com</a><br>> CC:<span class="ecxApple-converted-space"> </span><a href="mailto:gpxe@etherboot.org">gpxe@etherboot.org</a><br>><span class="ecxApple-converted-space"> </span><br>> Good day Aldrich,<br>><span class="ecxApple-converted-space"> </span><br>> Since there's no relationship between BIOS INT 13h drive numbers and<br>> drives that Windows finds, how do you propose to pass a virtual optical<br>> disc drive (ODD) to Windows?<br>><span class="ecxApple-converted-space"> </span><br>> For the HDD case, we already pass an iBFT (for iSCSI) or an aBFT (for<br>> AoE).
