After you configure all aspects of your HA pair, you need to verify that it is operating as expected in maintaining uninterrupted access to both nodes' storage during takeover and giveback operations. Throughout the takeover process, the local (or takeover) node should continue serving the data normally provided by the partner node. During giveback, control and delivery of the partner's storage should return to the partner node.
cluster::> storage failover show Takeover Node Partner Possible State Description ------ ------- --------- ----------------- node1 node2 - Waiting for giveback node2 node1 false In takeover, Auto giveback will be initiated in number of seconds seconds
cluster::> storage failover show Takeover Node Partner Possible State Description ------ ------- --------- ----------------- node1 node2 - Waiting for giveback node2 node1 false In takeover.
The following command displays all disks belonging to Node2 that Node1 can detect:
cluster::> storage disk show -home node2 -ownership Disk Aggregate Home Owner DR Home Home ID Owner ID DR Home ID Reserver Pool ------ --------- ----- ----- ------- ---------- ---------- ---------- ---------- ----- 1.0.2 - node2 node2 - 4078312453 4078312453 - 4078312452 Pool0 1.0.3 - node2 node2 - 4078312453 4078312453 - 4078312452 Pool0 ...
cluster::> aggr show -fields home-id,home-name,is-home aggregate home-id home-name is-home --------- ---------- --------- --------- aggr0_1 2014942045 node1 true aggr0_2 4078312453 node2 false aggr1_1 2014942045 node1 true aggr1_2 4078312453 node2 false 4 entries were displayed.
If takeover and giveback... | Then... |
---|---|
Is completed successfully | Repeat Step 2 through Step 8 on the partner node. |
Fails | Correct the takeover or giveback failure and then repeat this procedure. |
