  • activating targetcli service at boot is mandatory, otherwise your configuration won’t be read after a reboot
  • if you type cdtargetcli will display an interactive node tree
  • after configuration is saved you don't need to restart anything
  • the old scsi-target-utils doesn't support discovery authentication
  • targetcli allows kernel memory to be shared as a block SCSI device via theramdisk backstore. It also supports 'nullio' mode, which discards all writes, and returns all-zeroes for reads.
  • I'm having troubles configuring portals to listen both on any IPv4 addresses and any IPv6 addressesthe system has. I've still not figured that out entirely.
