We have an existing 4-node 9.5P5 AFFA300 metrocluster (site A - nodes A1,A2 || Site B - nodes B1,B2). Each node owns a mirrored aggregate. We're only expanding mirrored aggregates for site A (nodes A1,A2) with 64 disks. (A1) plex0 siteA 16 disks, plex1 siteB 16 disks and (A2) plex0 siteA 16 disks, plex1 siteB 16 disks. We're not adding new shelves just fully populating current shelves with disks. Can we just install disks and assign (storage assign disks) ownership and plex to corresponding nodes then expand aggregates via gui?
