Hello
Currently i have 3 nodes Cluster working correctly. All VMs are designed to failover to each host.
My goal is to add new node (4) but with some specific restrictions:
- it will host standalone VMs on it ( not as part of cluster )
- it will host only 3 VM as part of the cluster so in case needed i can migrate them to other hosts
- current VMs in existing clusters will not be "allowed" to migrate to new node ( lack of resources and no necessity )
for that reason i didn't configured access to its LUNs from new Host ( Host will be unchecked from possible owners )
My concern is in regards to validation tests ( executed with new host as candidate ):
1) obviously there is warning
"Disk with id {...} is visible or cluster-able only from a subset of nodes. This disk will be eligible for validation and clustering, but the possible owners for the disk resource will be set to limit which nodes can host this resource. If this was not your intention, review the "List All Disks" test to see which disks are visible to the nodes. Ensure that the disks you want to test are unmasked, that is, your masking or zoning does not prevent access to the disks. If the disks seem to be unmasked or zoned correctly but could not be tested, try restarting the servers before running the validation tests again"
As its my intention - can i dismiss that? or its better to allow new host to access those existing LUNs (csv) even if should not migrate?
2) there are some VMs that are simply turned off ( offline )
is that normal that reporst shows
"This resource is marked with a state of 'Offline'. The functionality that this resource provides is not available while it is in the offline state. The resource may be put in this state by an administrator or program. It may also be a newly created resource which has not been put in the online state or the resource may be dependent on a resource that is not online. Resources can be brought online by choosing the 'Bring this resource online' action in Failover Cluster Manager."
I hope i wrote it in the way you can get my point.
Thank You
