Re: Consolidating Storage Groups for VMware cluster
Here, I believe you want to migrate all VMs from one set of LUNs to another set without downtime.
Please correct me if I am wrong.
So say you have single masking view 'MV' with initiator group 'IG'(initiators of H1 and H2), Storage group 'SG1'(LUNA, LUNB) and Port group 'PG'. Hope initiator group 'IG' is created with -consistent_lun option enabled.
Now add new set of LUNs to Storage group 'SG1'(LUNC and LUND)
Scan devices(LUNC and LUND) from both the ESXi nodes and add as a datastore.
Migrate all the VMs using Storage vMotion from LUNs(LUNA, LUNB) to LUNs(LUNC and LUND).
