Ah, now I understand the issue. It would appear that there maybe a bug in the setup.pl script - I'll inform Engineering. The output of the esxcli command indicates that the MEM is installed. You can verify this be creating a volume and viewing the default path policy that was assigned. If you continue to run into issues, please open a Support ticket, and request that I be CC'd on the case. Thanks
Hi, i have a hard time getting MEM 1.3 to work on esxi6. I installed by means of the installation script and have 3 dedicated NIC's for my iSCSI setup. the MEM 1.3 VIB is also installed. But if i run: "setup.pl --query --server=x.x.x.x i get: You must provide the username and password for the server. Enter username:Enter password:No Dell EqualLogic Multipathing Extension bundle found.  What could be going wrong?
