Shutdown sequence of a DVS-SAN

Power shutdown procedure for the S2A9900 / SFA 7700 / SFA10K / SFA12K DVS-SAN, specific power down sequence is important to ensure a clean shutdown.

If your configuration does not have the equipment stated below then simply skip that section.

1. SAN clients
   
   Before shutting down the SAN server and storage components, make sure all SAN clients are done with their jobs and computers shutdown if possible.
   
   
2. Meta Data Servers (MDS)
   
   Open a terminal session as root and issue the follow two commands.  The first command stops the StorNext services, the second command stops the operating system and turns the server off.
   
   If dual MDSs are in use, start with MDS #2 first, wait 1 minute and then MDS #1.
   

   service cvfs fullstop
   poweroff

   The MDS should shutdown itself down after a short time, removed the power cables from the rear of the unit afterward.
   
   
3. Meta RAID - DH2730 / DH3730
   
   Connect to the controller via a browser or ssh and issue a shutdown command via the GUI interface or CLI. 
   
   Default user is 'manage', password is '!manage'.
