Hi Ramin,
Thank you for your question.
By our understanding,  Ex01 didn’t run any way, we could take a disaster recovery by the following steps:
Reset the computer account for the down server;
Install the operating system and name on the new server with the same name as the lost server. Recovery won't succeed if the server on which recovery is being performed doesn't have the same name as the lost server;
Join the server to the same domain as the lost server;
Install the necessary prerequisites and operating system components;
Log on to the server being recovered and open a command prompt;
Navigate to the Exchange 2013 installation files, and run the following command:
Setup /m:RecoverServer /IAcceptExchangeServerLicenseTerms
  7. After Setup has completed, but before the recovered server is put into production, reconfigure any custom settings that were previously present on the server, and then restart the server.

Then, we could recovery database from a backup or copy of a database by the following steps:
Create the recovery database;
This example creates the recovery database RDB2 on the Mailbox server MBX1 using a custom path for the database file and log folder:
New-MailboxDatabase -Recovery -Name RDB2 -Server MBX1 -EdbFilePath "C:\Recovery\RDB2\RDB2.EDB" -LogFolderPath "C:\Recovery\RDB2"
   2. Copy a recovered database and its log files, or restore a database and it log files, to the location we will use for our recovery database.
   3. Use Eseutil to bring that database into a clean shutdown state.
In the following example, EXX is the log generation prefix for the database (for example, E00, E01, E02, and so on).
Eseutil /R E01 /l E:\Databases\RDB1 /d E:\Databases\RDB1
  4. Create a recovery database. Give the recovery database a unique name, but use the name and path of the database file for the EdbFilePath parameter, and the location of the recovered log files for the LogFolderPath parameter.
The following example illustrates creating a recovery database that will be used to recover DB1.edb and its log files, which are located at E:\Databases\RDB1.
     New-MailboxDatabase -Recovery -Name <RDBName> -Server <ServerName> -EdbFilePath "  E:\Databases\RDB1\DB1.EDB" -LogFolderPath "E:\Databases\RDB1"
  5. Restart the Microsoft Exchange Information Store service:
Restart-Service MSExchangeIS
  6. Mount the recovery database:
    Mount-database <RDBName>
