    Hi @Chaitanya Kiran ,

    It is hard to find a book that include all SQL server HADR issues.

    Suggest you read below MS documents that include frequently asked questions about SQL HA.

    Troubleshoot SQL Server AlwaysOn issues
    Troubleshooting automatic failover problems in SQL Server AlwaysOn environments

    For understanding SQL HA\DR, suggest you read the blog SQL Server HADR overview.

    Hope this could help you. BTW, if you want to get more blogs or documents about this, suggest you using Google, type the key point SQL server HADR , the result will show you many blogs and documents related to this.

    Hey,

    There are useful guides available, which could help. As an example:

    In addition the following guide should help with configuration:
