Hi,
We have four Exchange servers, two in the main office and two in DR site. On both sides, one server has client access and hub transport role and second server has mailbox server role. We have a stretched DAG across two sites.Due to SAN maintenance, we need to first take Exchange Servers in DR site down, do the required maintenance on SAN, bring DR servers up and  then take the servers down in the main office.We do not want the databases to failover.What is the proper procedure for doing so?
In the DR site the Database Copy Activation Policy is "Blocked"
In the Main site the Database Copy Activation Policy is "Restricted"

Use start DAG maintenance mode script. So which ever server you want to do the task run this command

\StartDagServerMaintenance.ps1 -serverName Servername

Once task completed run

\StopDagServerMaintenance.ps1 -serverName Servername

You can find this in Script folder under Exchange Binary path. Later you can redistribute the db's again using redistribute PS command let according to activation preference number
