iSCSI targets known to work with iPXE

• SCST on Linux
• iSCSI Enterprise Target on Linux
• LIO (linux-iscsi.org) on Linux (see below)
• Windows Storage Server on Microsoft Windows
• COMSTAR on Solaris and OpenSolaris (and related products such as Nexenta and OpenIndiana)
• ISTGT FreeBSD iSCSI target implementation for multipath failover cluster nodes

Many iSCSI target products are based upon one of these technologies, so your target may be supported even if it is not listed here.

https://github.com/robinsmidsrod/comstar-soho-helper provides some scripts to ease the task of setting up a COMSTAR target.

This target works fine, but by default sends NOP-In messages that iPXE can't handle. This should not cause any issues, but has been known to cause trouble with grub2. If you encounter this, try disabling the NOP pings by setting the nopin_timeout node attribute to 0:

  lio_node --setnodeattr <TARGET_IQN> <TPGT> <INITIATOR_IQN> nopin_timeout 0

When setting up a iSCSI target using the Initiator software it must be explicitly pointed from target to client from the server side otherwise the iSCSI target will not be available or accessible from your network. This is done by: iSCSITarget → Expand iSCSI Targets → Right click on iSCSI target → Properties → iSCSI Initiators tab → Add

With that screen you can authorize a client by IQN, MAC Address, IP Address or DNS Name.
