Migrating to different SAN storage

[aurimask]

Hello,

I need to change storage array in my environment and want to check the migration path. Is this is as simple as

1. Connect new storage array to existing servers;

2. Create new Datastore for existing VMware Cluster;

3. Move VMs form old Datastore to new (Storage vMotion or Offline);

4. Delete old Datastore;

5. Disconnect old storage from servers;

Are there any issues with a vSphere 4.0 cluster doing migration this way?

Thanks

Sounds good. It should work this way.

I think your plan is solid!  When your Enterprise Storage Team disolves the LUN(s) I would rescan your storage adapters one more time, just to ensure all paths are gone.

This is the procedure I would recommend. Make sure indeed to "rescan" in between removing volumes etc to ensure changes are pushed down as well.

Hello,

Once you connect the new SAN Storage, make sure the paths redundancy and Multipathing along with Path selection for each lun is correct to make sure high availability and Active/Active paths are available.

Also, better to test all the redundancy components of the new SAN Storage correct, such as power, storage connections and array mapping by turning each components off/ON and then attempt your migration.
