I want to add 1TB extra capacity to existing 2TB (tdev) striped meta volume in VMAX. Can it be doing online without host interruption (e.g. unmask, unmap ...etc?)
Does anyone has the experience on expand stiped meta? And how long will it take if 2TB to 3TB?
For a Striped Meta Config, data is copied over to an identical BCV metavolume first, and then any new members are added to the original metavolume. New Hyper Devices must be added in the same size and configuration as in the original meta.
