Products

• VMware HCX

Issue/Introduction

Appliance(s) deployment job fails with reason: Interconnect Service Workflow GenerateAndPostConfig failed. Error: Operation timedout in state POST_CONFIG_VIX.

Environment

VMware HCX

Cause

The deployment task is failing because of a config error. The MTU set for the service mesh is "-1", which is an invalid entry. Following message is logged in app.log indicating a failure in getting PMTU test results:

<timestamps> UTC [InterconnectService_SvcThread-6429, IX:ae22966c-####-####-aa9ffcca1c83, J:975faff2, , TxId: 04352afb-####-####-c55b0290dd93] ERROR c.v.v.h.s.i.u.PmtuCollectionJob- Failed to get PMTU test results {}
org.apache.http.conn.ConnectTimeoutException:

And the following exception is logged (in app.log) upon the deployment task failure, suggesting a config error:

<timestamps> UTC [InterconnectService_SvcThread-230290, IX:36413769-####-####-56efe63d0a45, J:86700152, , TxId: 57901d9e-####-####-6240b7a5babd] WARN  c.v.v.h.s.i.GenerateAndPostConfiguration- Error from cgw: {"configResult":1,"rollbackResult":0,"configError":"/usr/sbin/ip link set dev vNic_1 mtu 4294967295: exit status 255","rollbackError":"","cmdFailed":false}

Resolution

Review the MTU configured for the affected service mesh, ensure a valid MTU value i.e. greater than 68 bytes is configured.
