Hello, I followed the video guide, but I'm stuck on iSCSI not found from vcenter Console, drdb seems to be running. See screen? running scripts again says "iscsi-ha already running: startup failed"

Thanks for help

It looks like that could be a firewall issue. We updated our installer last week due to a change to the default firewall configuration that ships with the latest release of XenServer, version 7.4. If you are using XenServer 7.4, make sure that you are using the HA-Lizard installer version 2.14. The version number is in the filename you downloaded. You can also download the correct installer from here:
halizard.org/release/noSAN-combined/hali...osan_installer_2.1.4

Also, to verify whether it is indeed a FW issue, can you check to ensure that 10.10.10.3 is actually loaded on the master host? From the shell, try "ip addr show | grep 10.10.10.3"

If you get no results, then something else is wrong as the IP address has not loaded on the master. A complete output of the installation or the installation log file would be helpful in determining where things went wrong.

Your backing storage device is read only.
You may have specified a disk or partition that is already in use.

Did you convert local storage when prompted by the installer (FYI - this only works when the local storage does NOT span more than 1 disk) or did you manually specify the device name (something like "/dev/sdb")
