Use this procedure to reseat a canister that is in service
state or because a service action has directed you.
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.
- 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.
- Verify that you have selected the correct node canister
and verify why you are reseating it.
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.
- Grasp the handle between the thumb and forefinger.
- Squeeze them together to release the handle.
- Pull out the handle to its full extension.
- Grasp the canister and pull it out 2 or 3 inches.
- Push the canister back into the slot until the handle starts
to move.
- Finish inserting the canister by closing the handle until
the locking catch clicks into place.
- Verify that the cables were not displaced.
- Verify that the LEDs are on.
