860 Fibre Channel network fabric is too big.

Explanation

The number of Fibre Channel (FC) logins to the node or node canister exceeds the allowed limit. The node or node canister continues to operate, but communicates only with the logins made before the limit was reached. The order in which other devices log in to the node or node canister cannot be determined, so the FC connectivity of the node or node canister might vary after each restart. The connection might be with host systems, other storage systems, or with other nodes or node canisters.

This error might be the reason the node or node canister is unable to participate in a system.

For the number of allowed logins per node, ensure that you are familiar with the maximum configurations that are supported by the system.

User response

This error indicates a problem with the Fibre Channel fabric configuration. It is resolved by reconfiguring the FC switch:
  1. If possible, use the management GUI to run the suggested actions for the associated service error code.
  2. Rezone the FC network so only the ports the node or node canister needs to connect to are visible to it.
