Overview

After upgrading to SRM 6.6 RC1, and adding EMC Unity arrays, these arrays are shown as unreachable - or if reachable, they do not show performance data.

Product section

Storage Resource Monitor

Resolution

The array is shown as unreachable - or if it is reachable, the performance data is not displayed.

The error message:

System.Net.WebException: The remote server returned an error: (422) Unprocessable Entity.

may be displayed.

Solution

Upgrade the firmware on the Unity array to 4.2 or newer.

SolarWinds SRM only supports EMC Unity with firmware version 4.2 and newer. Firmware 4.1.2 does not support block storage read and write latencies, so the performance job will fail.
