vSphere 6 Troubleshooting Mindmap | Storage

Here is my vSphere 6 troubleshooting course hand out for storage module.  This course is aimed at VCP and VCIX type certifications and to help vAdmins develop some processes for troubleshooting.

I have tried to create a mindmap and a thought process whereby the vAdmin reviews,

  • Baseline & trend Metrics,
  • Capacity,
  • Latency,
  • Connectivity.
The vAdmin then makes a decision on whether the issue is physical or virtual  using the mindmap for areas to review and check.
Root cause analysis can then be worked on with other teams  such as network and physical storage SMEs using metrics based on
  • Capacity Usage  – Depends on vendor or  design, consider risk, snapshots, swap file etc.
  • Disk Latency  – If  metrics show greater than 20 ms latency review as potential issue.
  • Kernel Command Latency – Anything greater  than 2ms maybe an issue. This should be as close to 0ms as possible.
  • Queue Latency      –  Anything greater than 1ms  latency then review.

Combined  with  end point information such as;

  • WWN or WWPN
  • IQN
  • IP Address configuration
  • Physical Port reference

anyway,  here is the vSphere 6 Troubleshooting Mindmap  for Storage
