HA failover configuration in 7mode Simulator.


Hi All,


Can someone help me in creating HA configuration in 7mode Simulator. 




Wow! Hat off ... Care to document it (blog or similar)?


That could be interesting.  I don't run a blog though.  Maybe I should start.


It would probably take a series of posts.  To get through it you need an ESX server, an NFS server, and a pretty good comfort level in the systemshell.




If you come around to doing it, please post a note here. Thank you!

Do you have a link to description how to do it?


No documentation that I could find.  To get it working I had to solve a few puzzles.  How to make NVRam persist accross reboots, how to get 2 VMs shared access to the simdisks, and how to get NVRam mirroring working accross nodes.  More accurately, I had to figure out how they solved them.  Ultimately it involved moving the simdisks to an nfs share, a number of settings in the vloader, and using the VMCI bus to simulate RDMA.  Its a complex config, and it only works on certain versions of VMware.




It is possible only in 7.x version (not sure if it is still available). 8.x version does not support HA pair anymore. 


Its possible, its just not supported, its not documented, and its extremely complex to configure.
