Applies to:

Oracle Cloud Infrastructure - Version N/A and later

Oracle Compute Cloud Service - Version N/A to N/A

Information in this document applies to any platform.

Goal

 There are sometimes iscsi messages recorded in the log like detected conn error (1011),detected conn error (1020) and detected conn error (1021). This article will illustrate how to decode/analyse those errors in Linux instance in OCI.

Solution

Error Decoding

Each ISCSI error's meaning is defined in the source code, as per the Diagnostic Steps section.

An example of error decoding:

error (1011) state (3)

This message is in two parts, the error and the state.
