Hello comunity I called checkhealth -svc -detail command in order to do some pre upgrade checks, and I got this error: Network Node1:Admin Errors recently detected on network Is this going to be a problem to perform upgrade? What is the reason for this, and how it can be fixed? Current OS version is 3.2.2 MU3 , patches 52,55 Thanks, |

It could be many things, ranging from failed hardware in your network switch via incorrect configuration to poor patch cables, bad/incorrect grounding, failed network adapter on the node(s) or incorrect configuration on the 3PAR. Depending on which it may or most likely not become an issue during upgrades. I would check the error counter (shownet -d (?)) to see if it's affecting all nodes equally. From the looks of your output it's only node1. I would either way start with replacing patch cables as those are cheap and ineffective to diagnose/troubleshoot. |

Thanks for the reply, all nodes and ports look ok except Node1 port0, where there is one error. shownet -d output: Admin interface on node 1 MAC Address: xx:xx:xx:xx:xx:xx RX Packets: 42984019 TX Packets: 74894585 RX Bytes: 4020825957 TX Bytes: 86502528373 RX Errors: 1 TX Errors: 0 RX Dropped: 0 TX Dropped: 0 RX FIFO Errors: 0 TX FIFO Errors: 0 RX Frame Errors: 1 TX Collisions: 0 RX Multicast: 0 TX Carrier Errors: 0 RX Compressed: 0 TX Compressed: 0 Detailed Tcp stats on node 1 RtoAlgorithm: 1 RtoMin: 200 RtoMax: 120000 MaxConn: -1 ActiveOpens: 1111330 PassiveOpens: 1599335 AttemptFails: 2878 EstabResets: 489595 CurrEstab: 5 InSegs: 50591028 OutSegs: 49911798 RetransSegs: 6715 InErrs: 0 OutRsts: 733 |

I would replace network cable and possibly try another port on the management switch. Seems to very much be a single issue. |
