In a Database Availability Group, when you copy a database from an Exchange Server and place it on a different Exchange Server, the process is called ‘Seeding.’ Thus, it becomes a replica of your database where the entire data is present. Seeding is performed using the ‘Update-MailboxDatabaseCopy’ cmdlet.
In a Database Availability Group, the active copy of the database is accessed by users. However, other database copies are updated by replicating the active database. However, you may face errors during the process due to various reasons. In that case, you may need to update other servers from a passive copy. You need to suspend the database copy and then proceed with reseeding. We will discuss the process here in detail.
First of all, fix the issue due to which the active database has failed. Then only try to update the database.
The cmdlet will seed the copy of the DB322312 on Server NDR32 using NDR53 as the Source Server.
If the cmdlet did not run correctly, then it will not create a copy at the destination server, and there will be an error at the event log.
MSExchangeRepl Event ID: 4113
Database redundancy health check failed. Database copy: DB322312 Redundancy count:1
Error: Passive copy ‘DB322312\NDR32’ is not in a good state. Status: FailedAndSuspended
You can also check the copy status using the Exchange Management Shell with a cmdlet.
To fix the error, you need to update the mailbox database copy running the cmdlet:
For longer reseeds, if you want to keep the PowerShell closed, then use the below cmdlet:
The DeleteExistingFiles cmdlet deletes the existing log files to avoid any error messages:
Before running the reseeding cmdlet, the Exchange Administrator should check multiple points necessary for copying the database.
You can also use the Exchange Admin Center to reseed the copy process.
So, this is the whole process of handling a ‘mailbox database copy failed and suspended’ situation. Thus, you can handle the situation using various PowerShell cmdlets and Exchange Admin Center.
But, if the database faces any corruption, sometimes the copy process will not be fruitful. In that case, try a professional Exchange recovery tool, which makes Exchange server working more easy and secure.
Kernel for Exchange Server recovery tool is a powerful Exchange database corruption remover that can access the entire database and remove the corruption in the least time. After recovering the database, you can directly save the data to the destination Exchange Server or even Office 365 cloud. Also, this tool supports all the latest versions of Exchange Server, including Exchange 2019.
When you try to seed a mailbox database, you may get an error ‘Mailbox Database Copy Failed & Suspended.’ However, after taking some precautions, you can reseed the database. Sometimes, you may face frequent issues due to the corruption of the Exchange database. This issue can be fixed only using a professional Exchange server repair tool.
