Questions about Gatekeepers properties for ECC and SMC on a VM

> need to have all properties and options should be chosen for the rdms used for the 2 servers

Recommend to add 6 GKs to Solutions Enabler VM and 8 GKs to ECC VM.

Again we need enough to perform all concurrent Symmetrix commands and queries without running into a condition in which commands are delayed or rejected for lack of a gatekeeper resource.

It is fine to add GKs to existing VMware hosts masking view.

> and is that Configuration required from VCENTER side or from SMC/Storage side ?

Create GKs and add it to existing VMware hosts masking view.
Gatekeepers require only a small amount of space, 3 MB (3 cyl) for Enginuity levels 57xx, 58xx and higher, and 3 MB (6 cyl) for Enginuity levels of 56xx and lower.

No specific settings or requirements at vCenter level.

Also I would recommend please follow below Primuses

emc255976 : Gatekeepers - All You Need to Know

16. Virtualization/Cluster/Migration or Application Specific Gatekeeper Requirements.

Virtual Server Environments :
Virtual Server environments often permit the movement of a guest operating system instance from one physical server to another.
If that instance is doing Symmetrix management or control, the Gatekeepers being used must be visible to that instance on whatever
physical server it is running upon. As a result, the Gatekeeper devices must be made visible to the various physical servers the guest may operate upon.
Note that the rule for not sharing Gatekeepers remains, and that the guest operating system image with its Solutions Enabler
instance must run on only one physical machine at any given time, and only one instance using the Gatekeeper at any one time

emc248427 : Can gatekeepers be shared on virtual machines or physical ESX servers in a VMware Cluster?

Sharing gatekeepers across different virtual machines  is NOT supported.
Sharing gatekeepers at the physical Clustered ESX server level IS supported

VMware ESX, multipathed Gatekeepers using VMware NMP require a policy of FIXED. RR policy is NOT supported.

Gatekeepers must be presented to the virtual machine as RDM in physical compatibility mode for Solutions Enabler to operate properly.

emc193692 : How should I present gatekeepers to a VMware virtual machine?

Gatekeepers should be presented as physical RDM devices.
