Dependent volume names that start with IFS are file volumes that are
used by the file modules to provide file systems. Turn off these file
modules. See the procedure "Turning off the system".
5. If the I/O group is still online, shut down the I/O group by using the control
enclosure CLI.
a. Identify the two node canisters in the I/O group that are provided by the
control enclosure to be replaced.
b. To shut down each node, issue the following CLI command once for each
of the two node canisters:
stopsystem -force -node <node ID>
c. Wait for the shutdown to complete.
6. Verify that it is safe to remove the power from the enclosure.
For each of the canisters, verify the status of the system status LED. If the
LED is lit on either of the canisters, do not continue because the system is still
online. Determine why the node canisters did not shut down in step 3 on
page 335 or step 4 on page 335.
Note: If you continue while the system is still active, you risk losing the
clustered system configuration and volume cache data that is stored in the
canister.
7. Turn off the power to the enclosure using the switches.
8. Record which data cables are plugged into the specific ports. The cables must
be inserted back into the same ports after the replacement is complete;
otherwise, the system cannot function properly.
