Failover
Stop the CIFS server on source NetApp
vserver cifs stop -vserver netappsvm001_files
Remove the netbios alias (if one exsists) on source NetApp
vserver cifs remove-netbios-aliases -vserver netappsvm001_files -netbios-aliases fileserver01
Break the replication of at the DR end
Browse the share at the DR end to make sure its writable
Repoint DNS so (in this example) fileserver01 now points to the DR NetApp
Flushdns cache then ping fileserver01 and make sure it resolved to the DR IP address
Add netbios alias at DR end (the client may need to reboot before this works)
vserver cifs add-netbios-aliases -vserver netappsvm002_files -netbios-aliases fileserver01
Re-assign the SPNs on fileserver01 AD account, this must be carried out on a Windows machine with rights to update the computer object for the NetApp CIFS server.
setspn -D HOST\fileserver01 netapp001 setspn -D HOST\fileserver01.somedomain.com netapp001 setspn -D CIFS\fileserver01 netapp001 setspn -D CIFS\fileserver01.somedomain.com netapp001 setspn -S HOST\fileserver01 netapp002 setspn -S HOST\fileserver01.somedomain.com netapp002 setspn -S CIFS\fileserver01 netapp002 setspn -S CIFS\fileserver01.somedomain.com netapp002
Failback
Removed net bios alias from DR NetApp
vserver cifs remove-netbios-aliases -vserver netappsvm002_files -netbios-aliases fileserver01
Repoint DNS so (in this example) fileserver01 not points to the source NetApp
Add Net Bios alias back on the primary NetApp (source NetApp)
vserver cifs add-netbios-aliases -vserver netappsvm001_files -netbios-aliases fileserver01
Start the CIFS server on the source NetApp:
vserver cifs start -vserver netappsvm001_files
Re-assign the SPNs on fileserver01 AD account, this must be carried out on a Windows machine with rights to update the computer object for the NetApp CIFS server.
setspn -D HOST\fileserver01 netapp002 setspn -D HOST\fileserver01.somedomain.com netapp002 setspn -D CIFS\fileserver01 netapp002 setspn -D CIFS\fileserver01.somedomain.com netapp002 setspn -S HOST\fileserver01 netapp001 setspn -S HOST\fileserver01.somedomain.com netapp001 setspn -S CIFS\fileserver01 netapp001 setspn -S CIFS\fileserver01.somedomain.com netapp001
Re start and re sync replication
