1052: Inter-canister PCIe link degraded

Explanation

The inter-canister PCI Express link is operating with reduced capacity. This might be a fault in either canister or the midplane. However, it is most likely to be a fault in the node canister that reported the problem.

User Response

• Unless both nodes in the I/O group are online, fix the problem that is causing the node to be offline first.
• Find which node reported the 1052 error by using the object_id or object_name value for the event in the event log. Check which node canister has that node_id.
• Use the CLI command svctask rmnode to delete the node canister that reported the problem.
• Replace the canister that reported the problem with the new canister.
• Wait for the new canister to be automatically added to the system.
• If the error is auto-fixed, then finish; otherwise, continue.
• Use the CLI command svctask rmnode to delete the other node canister.
• Replace the other node canister with the old node canister.
• Wait for that node canister to be automatically added to the system.
• If the error is auto-fixed, then finish; otherwise, continue.
• Replace the enclosure.
• If the error is auto-fixed, then finish; otherwise, call IBM for further support.
