Issue



"Unable to attach to one of the drives" error appaered when Redirected the restore of an Exchange Mailbox Store to a Recovery Storage Group (RSG) created on a different server.


Error




Final error: 0xa000848c - Unable to attach to one of the drives.
Final error category: Resource Errors


Cause



This issue may occur if the Exchange server the restore is being redirected to does not have the same storage group or database name as the original server backed up. This also means the Recovery Storage Group (RSG) being redirected to does not have the same name as the original strorage group that was backed up causing the restore to ultimately fail due to the name inconsitency.


Solution



On the server which hosts the RSG, check if there is a storage group with the same name as the original storage group that was backed up.  If no such storage group exists on the server, then create a storage group with the same name on the recovery server.  For example if the store was backed up from a storage group named as "Second Storage Group" and on the recovery server there is no such storage group, then create a storage group with the name "Second Storage Group" on the recovery server.  Next, create the RSG again for the newly named storage group and run the restore selecting the correct options.
