we have recently completed NDM migration for a windows host from vmax40k to AFVMAX using EMC NDM method.

After migration, we noticed that the migrated luns are able to expand from storage side but windows OS is not able to see the extended space.

we tried to give a new lun via same vmax and expand it and windows OS was able to see it and extend at OS level.

are the lun migrated by NDM not able to expanded? because they have two lun identity? external and internal?
