How to access the Home directory even when logged in via secondary domain controller?

One of my customers is going for three physical servers with Windows 2012 Server OS in them. One would be the Primary Domain Controller (PDC), second a Tally server (accounting package) and third will run three Hyper V with WSUS, Antivirus Server and Backup Domain Controller (BDC) running in three Hyper V server instances.

They would be directly connected to IBM Storwize V3700 SAM storage either via HBA FC or via SAS card serial to the storage. They have 250 users and each user with get around 10MB of home directory storage on the SAN storage when logged via the PDC. This can be done. However my customer wants that when the PDC goes down and users are logged via BDC, they should still be able to access their respective 10MB home directory on the SAN storage.

Can somebody help me in suggesting, how to manage this?

    The BDC automatically gets the same information that the PDC uses when people log in from the PDC (it is periodically replicated to the BDC), when people log in, the authenticating domain controller will issue then the correct path to their home directory, their login scripts, etc. You do not need to do anything special.

    Even when the PDC is up and running, it may not be handling the logins for all users anyway. If it is busy, the BDC will also be logging people in too, particularly at the start of a business day when most people will be logging in within a relatively short timeframe.

    Also, if the PDC goes down, the BDC will automatically be promoted to the PDC. When the original PDC is brought back up, it will be running as a BDC and need to be pormoted to PDC again.
