About this task
v
This procedure refers to
HA pairs
, which in releases prior to Data ONTAP 8.0
were called
active/active configurations
.
v
All other components in the system must be functioning properly; if not, contact
technical support.
v
You can use this procedure with all versions of Data ONTAP supported by your
system. A 7-Mode system refers to a system running Data ONTAP 8.x operating
in 7-Mode or releases prior to Data ONTAP 8.0.
Shutting down the node
You shut down a node using different procedures, depending on whether it is a
stand-alone system or part of an HA pair.
Shutting down a node in an HA pair
To shut down the node, you must determine the status of the node and, if
necessary, take over the node so that the partner continues to serve data from the
node's storage.
Before you begin
Note:
If your system has two controller modules in the same chassis, you must
leave the power supplies turned on at the end of this procedure to provide power
to the partner node.
Procedure
1.
Check the status of the target node (the node you want to perform maintenance
on) by entering the following command at the system console of either node:
For...
Issue the command...
7-Mode
cf status
Clustered Data ONTAP
storage failover show
2.
Take one of the following actions, depending on the result of the
cf status
or
storage failover
command:
If...
Then...
Neither node is in takeover mode
Go to the next step in this procedure.
The partner node took over the target node
The target node is in a state where you can
begin removing it from the system chassis.
Continue with the task "Opening the
system".
The target node took over the partner node
1.
Correct the problem that caused the
takeover.
2.
Go back to the beginning of this
procedure.
3.
Take over the target node by entering one of the following commands from the
partner node’s console:
For...
Issue the command...
