Physically moving an installation
This is probably more of a question for the XS forums but thought I'd get
you alls perspective too.
We are moving buildings and need to move our CS + XS hardware. What it the
recommended way to do that?
I was thinking of the following steps:
1) stop the CS management server
2) pause/stop every VM using XenCenter (CS system VMs last?)
3) shutdown XS hosts
4) shutdown Management Server host (also NFS server)
5) move
On the other end I would:
1) boot Management Server Host (make sure CS Management Server is stopped,
and NFS is up)
2) boot XS hosts
3) Use XenCenter to start all VMs (CS system vms first?)
4) Start CS Management Server
Anything I am missing?
thanks,
Carlos

Thanks for the suggestions. Move is not for another month. Going to do a
dry run next week.

Kirk is right, us CS to shutdown all VMs, this will remove any VM to Host mapping and ensure all VMs are safely stored on storage.
I would seriously consider taking a backup of storage before moving it as you never know someone could drop the chassis etc.
Once all VMs are stopped, place all storage into maintenance mode, then do the same with Hosts, this will ensure all System VMs are stopped.
You can then shutdown your CS and DB nodes, hosts and storage.
Once everything is in its new home, bring storage online, then hosts and do some basic tests before powering on the DB and CS nodes.
Once DB and CS nodes are online, bring storage and a couple of Hosts out of maintenance mode and ensure System VMs come online and function correctly. Test importing / exporting templates etc to test all network components.
Once you are happy everything is working OK, bring remaining hosts out of maintenance and start to bring your Guest VMs online, but do so in small batches and test to make sure everything is performing normally etc.

I would use CS to shutdown all instances. Then shutdown the management server, then hosts, then reverse it on the other end. But wait for others to chime in before moving forward.

I would use CS to shutdown all instances. Then shutdown the management
server, then hosts, then reverse it on the other end. But wait for others
to chime in before moving forward.
