\nusing gpxe boot strap loader (for sanboot option) <\/p>\n
Here below I use Tiny Pxe Server<\/a>. The root path : iscsi:192.168.1.100:tcp:3260:0:test recommended: do not fill the router field due to a bug within ms iscsi initiator and the gateway (see here<\/a>)<\/p>\n Note : as an option, you can skip the dhcp\/tftp server by using a boot disk (floppy or cdrom) made by gpxe.<\/p>\n Go there Rom-o-matic.net<\/a>, #!gpxe Use the generated boot disk on your physical computer or in your virtual image.<\/p>\n 2.Setup iscsi target <\/strong><\/p>\n –iscsi cake<\/a> can mount any thing like vhd, vmdk, disk, etc. The iscsi target can be used either during the installation or for the transfer of an existing windows installation to an iscsi volume.<\/p>\n Here below a screenshot of one xp disk mounted in Starwind (free for one connection). 3.Install new OS, or transfer existing OS, to an image that will be shared over iscsi.<\/strong><\/p>\n Installation choices : <\/p>\n -(1) install directly to an iscsi target (vista, windows 2008 or windows 7). see howto<\/a><\/p>\n -(2) have a vmdk point to a blank img file (monolithic vmdk option) and install thru vmware. See below how to.<\/p>\n Here below vmware settings to install xp on a physical device (choice 2 above). -(3) install to a local physical disk and clone it to an img file afterwards. See below how to.<\/p>\n If you have an existing windows, transfer it to an image file using a one to one disk cloning software. Note1 : CloneDisk can create a vmdk file for you, pointing to the image file of your disk. Note2 : QEMU can also use the raw image file. 4.Install iscsi boot support in your operating system (before cloning\/transfer)<\/strong><\/p>\n For xp : http:\/\/etherboot.org\/wiki\/sanboot\/winnt_iscsi<\/a> for w2k3: http:\/\/etherboot.org\/wiki\/sanboot\/win2k3<\/a><\/p>\n Not needed for W2k8, Vista and Windows7 as they support natively iscsi boot. 5.Boot over iscsi !<\/strong><\/p>\n If not done yet, setup your iscsi target (see step 2) with a prepared image file.<\/p>\n Unless you have an hba with iscsi support or network card with gpxe built in, setup your pxe server (step 1).<\/p>\n Lets test it in vmware.<\/p>\n See below the vm settings (diskless!) see below the disk seen from Windows , once booted over iscsi. Constraint : network card needs to be the same before\/after in order to boot. 6.Summary :<\/strong><\/p>\n -we have setup a pxe server (dhcp & tftp & gPXE) possible improvements:<\/p>\n -flash your network card with gPXE, turning it into a boot on san device. -flash your motherboard network rom with gPXE. -Use a gpxe nic rom in vmware to skip the dhcp\/tftp part (nbios.filename vmx parameter). Steps: 1.Setup pxe server with gpxe 2.Setup iscsi target 3.Install new OS, or transfer existing OS, to a volume that will be shared over iscsi. 4.Install iscsi boot support 5.Boot over iscsi ! 6.Summary : Lets start! 1.Setup bootstrap loader with gpxe using gpxe boot strap loader (for sanboot option) Here below I use Tiny […]<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"open","template":"","meta":{"footnotes":""},"categories":[16,10,45,28],"tags":[],"class_list":["post-180","page","type-page","status-publish","hentry","category-boot","category-iscsi","category-pxe","category-tinypxe-server","category-16-id","category-10-id","category-45-id","category-28-id","post-seq-1","post-parity-odd","meta-position-corners","fix"],"_links":{"self":[{"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=\/wp\/v2\/pages\/180","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=180"}],"version-history":[{"count":29,"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=\/wp\/v2\/pages\/180\/revisions"}],"predecessor-version":[{"id":962,"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=\/wp\/v2\/pages\/180\/revisions\/962"}],"wp:attachment":[{"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=180"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=180"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/labalec.fr\/erwan\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=180"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

\ndhcp extra option : 175.6.1.1.1.8.1.1
\nwe set keep-san=1 (in case we want to install directly to san) and dhcp priority=1 to over rule any dhcp server on your lan.<\/p>\n
\n-choose floppy image as output format (or cdrom),
\n-choose \u00ab\u00a0all-drivers\u00a0\u00bb as NIC Type,
\n-tick time_cmd and digest_cmd,
\n-and use the following embedded script :<\/p>\n

\n–rocket division startwind<\/a> can mount image files,disks, etc.
\n–openfiler<\/a> \/ freenas<\/a> can also act as iscsi target but can \u00ab\u00a0only\u00a0\u00bb create disks, not mount them.<\/p>\n

\nNote that \\\\.\\physicaldrive1 is actually a vmdk pointing to my disk image file (which we will use later in starwind).
\nSee lower in that page on how to make that vmdk.

\nYou may even be able to boot on your image file from within vmware server.
\nIf so, dont forget to install the scsi vmware driver before cloning and to restart in safe mode on the target vm guest.<\/p>\n![\"\"](\"https:\/\/labalec.fr\/erwan\/images\/clonedisk2.png\")
\n
<\/p>\n
\nThen apply this http:\/\/support.microsoft.com\/kb\/314082 before launching in QEMU to avoid a 0x7b BSOD.<\/p>\n
\nNote : once the iscsi initiator installed on XP, dont forget to run the SAN Boot Configurator (http:\/\/www.etherboot.org\/wiki\/sanboot\/winnt_iscsi_sanbootconf<\/a>)<\/p>\n
\nNote : you have to set the msiscsi service to start=auto (and possibly to add the target to the iscsi initiator?).
\n(sc config MSiSCSI start= auto)<\/p>\n

\nYou can add another network card before migrating to another computer, see here http:\/\/etherboot.org\/wiki\/appnotes\/port_winnt_sanboot<\/a> .<\/p>\n
\n-we have setup a scsi target
\n-we have installed windows to a flat file and served that file thru the iscsi target (in a vmware guest)
\n-we have setup iscsi boot support in our windows
\n-we have started a diskless computer (in a vmware guest)
\n-we have booted on san using the iscsi protocol thanks to gPXE<\/p>\n
\nsee http:\/\/www.etherboot.org\/wiki\/romburning<\/a>
\nIn that case you dont need a pxe server anymore, config (target and rootpath) is saved directly in the network card.<\/p>\n
