Issue/Introduction

When attempting to open the cdm probe config via IM, the config is taking a long time to open.  Also, it is throwing Run-time error '91' error when saving config.  We also see that the RawConfig isn't opening (or timing out).

Cause

This server had several thousand IOSTAT drives.  Having this many drives discovered in the config brought the cdm.cfg file up to 400K+ lines and 10MB in size.  Reading and writing to this file timing out and in some cases, even causing file corruption.

Environment

Release : 20.3

Component : UIM - CDM WITH IOSTAT

Resolution

After manually removing the unnecessary, unmonitored iostat drives to reduce the size of the cfg file, the probe was able to collect data without issues and IM was able to open the cfg without errors.  We followed the below document to ensure that these cluster/cdm configurations were properly deployed.
