PowerFlex: Cursor Disappears, and Screen Stops Responding When Manually adding IP Address During Deployment
Summary: The PFxM 4.x UI Screen stops responding, and the cursor disappears when manually entering hostnames and IP addresses in the final deployment screen.
Symptoms
Scenario
When deploying a Resource group and manually adding "user entered IP" addresses in the final deployment settings screen, the web browser randomly stops responding and the cursor prompt disappears (stops blinking).
Symptoms
When adding IP addresses or hostnames in the final M and O deployment screen, the browser stops responding and can eventually become unresponsive.
The not responding and cursor disappearance may get worse throughout the process of entering information for other nodes.
The PFxM UI session may timeout if the pause is too long:
The deployment wizard shows a 401 error:
Message seen in the thin-deployer log:

Impacted Versions
PowerFlex 4.5.1 and earlier
Impact
Unable to manually enter all the IP addresses before the browser times out.
Cause
Installed browser extensions along with the deployment wizard portion of the code are contributing to the browser not responding:
Resolution
Workaround
Instead of manually adding all the IP addresses for nodes or SVMs, check off "PowerFlex Manager Selected IP," which uses DNS for a hostname to ESXi IP address translation. Also, all other IP addresses should be pulled from the pool of IP addresses defined in the Networks section.
Fixed In Version
The wizard is being rewritten, and the issue should be resolved in an upcoming PowerFlex release.
