Failover
- Stop the CIFS server on source NetApp:
vserver cifs stop -vserver netappsvm001_files
- Remove the netbios alias (if one exists) on source NetApp:
vserver cifs remove-netbios-aliases -vserver netappsvm001_files -netbios-aliases fileserver01
- Break the replication of the share on the DR NetApp.
- 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.
- Flush DNS cache then ping fileserver01 and make sure it resolves 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
- Remove netbios alias from DR NetApp:
vserver cifs remove-netbios-aliases -vserver netappsvm002_files -netbios-aliases fileserver01
- Repoint DNS so (in this example) fileserver01 now points to the source NetApp.
- Add netbios alias back on the 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
