NetApp - Cluster takeover and giveback procedure.

1.  To take over partner node, we have to make sure there will be 1-2 minutes connectivity lost (CIFS/NFS)
2. 2.      Release ASUP before giveback options autosupport.doit per-takeovernode1
   3.       node2> cf takeover –f (node1 is takeover by node2)
   4.       node2> cf: takeover initiated by operator
   5.       node2 (takeover)> – Which means takeover completed.
   6.       node2 (takeover)> partner  (To see partner status )
   7.       node2 /node1>
   8.       To do giveback follow from step 9
   9.       When the system isn’t in partner context  and if prompt shows as “ node1/node2>”, follow from step 4, if prompt shows as “node2(takeover)>” follow from step 5
   10.   node1/node2>  partner
   11.   node2(takeover)> cf status
   node2 has taken over node1.
   node1 is ready for giveback.
   12.   Release ASUP before giveback options autosupport.doit per-giveback1node
   13.   node2(takeover)> cf giveback
   14.   If cf giveback is unsuccessful, try forcegiveback..
   15.   node2(takeover)>  cf giveback –f
   16.   once the giveback completes, login to node1 and do health check
   17.   node1> sysconfig –r
   18.   node1>  sysconfig –v
   19.   node1>  storage show disk –p
   20.   node1>  vfiler status –r
   21.   node1>  vfiler run vfilername exportfs
   22.   node1>  vfiler run vfilername cifs shares
   23.   node1>  vol status –s
   24.   node1>  vif status
   25.   node1>  ifconfig –a
   26.   node1> options autosupport.doit post givenback1node
