vims,
Here is my quesitons about using snapmirror. I only want to migrate some luns in a volume. As I understand, snapmirror only can copy entire volume not luns. Do you mean that I have to copy the entire volume first, then map only luns I need?
Also, as I understand, I still need to resync in last step while the lun is un-accessable, so, during this short time, there would be still a short downtime, is not it? even though
1. Yes it is correct. You can delete luns you do not need later on and use luns of your choice.
2. yes - resync is the vital step. I did it in MS SQL environment, stopped SQL server first - resync - reconnect
