PowerFlex management cluster (KVM)

The PowerFlex management cluster (KVM) feature is considered as technology preview. Contact PowerFlex product management for details on this option.

Management

Power on the switches
- On all switches, confirm Green status lights
- For out-of-band management switches, log in and confirm:
  - Validate the configuration, type
```
show running-configuration
```
  - Validate uplinks, type
```
show interface brief
```
  - Validate iDRAC connectivity, type
```
show interface brief
```
  - Validate swtich hardware, type
```
 show hardware (cisco only)
```
- For non-management switches, log in and confirm:
  - Validate the configuration, type
```
show running-configuration
```
  - Validate uplinks, type
```
show interface brief
```
  - Validate port channels, type
```
show port-channel summary
```
  - Validate switch hardware, type
```
show hardware (cisco only)
```
Power on the management nodes
- Confirm the status LED indicator light is off on each management node. The light on the front of the node should not be blinking amber. See for more information.
- Log in to each iDRAC to confirm no hardware alarms or errors and confirm the OS booted successfully.
Verify the following in the management PowerFlex Manager:
- Check alerts: Go to Monitoring > Alerts.
- Check management diagnostic status (for PowerFlex 4.8 and above), and ensure all statuses are green.
  - Go to Monitoring > Management Diagnostics.
  - Run all management diagnostic tests.
- SDS
  - Go to Block > SDSs.
  - Ensure the state is Healthy.
  - Ensure the connected state is Connected.
- SDC
  - Go to Block > Hosts.
  - Ensure the connected state is Connected.
- Verify health of resources: Go to the Resources tab and confirm the Health Status.
