I’m trying out Proxmox on my ESXi servers, so as before, I’m trying to install on an iSCSI boot drive.<\/p>\n\n\n\n

I used this the following websites for reference:
https:\/\/forum.proxmox.com\/threads\/install-pve-directly-on-iscsi-target.101750\/<\/a>
https:\/\/library.netapp.com\/ecmdocs\/ECMP1217221\/html\/GUID-2A8546C7-347A-40B0-B937-4B31DAAA16DA.html<\/a><\/p>\n\n\n\n

First step, make sure your LUN target has ID of 0. ESXi didn’t need this, so it was set to a random number, and the LUN would NOT show up in \/dev. This took a long time to figure out. So enjoy that.<\/p>\n\n\n\n

I’ll assume iSCSI target is set to what it needs to be (I allowed all IPs\/IQNs to see the LUN for setup), your network card is set to boot (you can use iPXE as well, but I’m not basic), and your LUN ID is 0. See the first few steps of this post: https:\/\/blog.mctechnologies.net\/?p=145<\/p>\n\n\n\n

Step 1: Boot your Proxmox install ISO, and get to a command line.<\/p>\n\n\n\n

Select “Advanced Options” <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Select either of the Debug modes<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

On your first prompt hit “Ctrl-D”. This will get you to a second prompt with your network card driver loaded.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Step 2: Set up networking, install necessary packages for iSCSI, add your target:<\/p>\n\n\n\n

Find your network card name (I’m using the second NIC): <\/code>ip a
Get it up: ip link set enp4s0f1<\/em> up
Set to an IP address that is right for you: ip addr add 10.1.60.5<\/em>\/24 dev enp4s0f1<\/em><\/code>
Check if its working right: ip a
Ping your iSCSI target…<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 3: Install iSCSI packages needed to see the LUN (the versions might be different, just tab the last bit of the file name):<\/p>\n\n\n\n

dpkg -i \/cdrom\/debian\/proxmox\/packages\/libisns0_0.101-2+b1_adm64.deb\ndpkg -i \/cdrom\/debian\/proxmox\/packages\/libopeniscsiusr_2.1.8-1_adm64.deb\ndpkg -i \/cdrom\/debian\/proxmox\/packages\/open-iscsi_2.1.8-1_adm64.deb<\/code>\n(errors are ok, doesn't matter)<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Step 4: Add the LUN<\/p>\n\n\n\n
Create a folder structure needed for iscsiadm to use:  <\/p>\n\n\n\n
mkdir \/run\/lock
mkdir \/run\/lock\/iscsi<\/code><\/p>\n\n\n\n
Set your initiator name in Proxmox, or in your iSCSI target by using this file \/etc\/iscsi\/initatorname.iscsi
InitiatorName=iqn.1991-05.com:vmh2<\/em><\/code><\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Start iscsid:  service iscsid start<\/code><\/p>\n\n\n\n
(These next steps will mount all available nodes, this works for me)<\/p>\n\n\n\n
Discovery available LUNS (change the IP): 
iscsiadm –mode discovery –op update –type sendtargets –portal 10.1.60.2<\/var><\/p>\n\n\n\n
Add all the nodes:
iscsiadm –mode node -l all<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Get back to installing Proxmox by typing CTRL-D<\/p>\n\n\n\n
Do not Automatically reboot after install (Not exactly sure if this is necessary)!<\/p>\n\n\n\n
Install as usual, but there is one more step at the end..<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
It’ll ask you to reboot as the only option, itll actually take you to a command prompt<\/p>\n\n\n\n
Step 5: Need to configure one last thing before reboot<\/p>\n\n\n\n
Mount the new file systems<\/p>\n\n\n\n
mount \/dev\/pve\/root \/mnt\nmount -o bind \/dev \/mnt\/dev\nmount -o bind \/proc \/mnt\/proc\nmount -o bind \/sys \/mnt\/sys<\/code>chroot \/mnt \/bin\/bash<\/code><\/pre>\n\n\n\n
Add and modify iscsi.initramfs:<\/p>\n\n\n\n
vi \/etc\/iscsi\/iscsi.initramfs<\/code><\/p>\n\n\n\n
Add the following line:
ISCSI_AUTO=true<\/code><\/p>\n\n\n\n
Update GRUB, run:
update-grub && update-initramfs -u -k all<\/code><\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Hit CTRL-D (2x) and it will reboot!  It SHOULD load into Proxmox<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
