Explanation
A canister to canister communication error can appear
when one canister cannot communicate with the other.
User Response
Reseat the passive canister, and then try reseating
the active canister. If neither resolve the alert, try replacing the
passive canister, and then the other canister.
A canister can be
safely reseated or replaced while the system is in production. Make
sure that the other canister is the active node before removing this
canister. It is preferable that this canister shuts down completely
before removing it, but it is not required.
- Reseat the passive canister (a failover is not required).
- Reseat the second canister (a failover is required).
- If necessary, replace the passive canister (a failover is not
required).
- If necessary, replace the active canister (a failover is required).
If
a second new canister is not available, the previously removed canister
can be used, as it apparently is not at fault.
- An enclosure replacement might be necessary. Contact IBM support.
