7. Set the service address of the canister to one that can be accessed on the

Procedure: Reseating a node canister
Use this procedure to reseat a canister that is in service state or because a service
action has directed you.
About this task
Verify that you are reseating the correct node canister and that you use the correct
canister handle for the node that you are reseating. Handles for the node canisters
are located next to each other. The handle on the right operates the upper canister.
The handle on the left operates the lower canister.
Procedure
1. Verify the clustered-system status LED on the node canister. If it is
permanently on, the node is active. If the node is active, no reseating is
required.
2. Verify that you have selected the correct node canister and verify why you are
reseating it. Go to “Procedure: Identifying which enclosure or canister to
service” on page 52.
If you reseat a node that is active, it cannot store its state data and cannot
restart without other service actions.
If the other node canister in the enclosure is not active, reseating the node
canister while it is active results in loss of the data on your volumes and the
system is unavailable to hosts.
3. Grasp the handle between the thumb and forefinger.
4. Squeeze them together to release the handle.
5. Pull out the handle to its full extension.
6. Grasp the canister and pull it out 2 or 3 inches.
7. Push the canister back into the slot until the handle starts to move.
8. Finish inserting the canister by closing the handle until the locking catch clicks
into place.
9. Verify that the cables were not displaced.
10. Verify that the LEDs are on.
