The issue may also arise when tested with different browsers and various ME5 firmware versions.

Cause

The command becomes unresponsive indefinitely, potentially resulting in the web session becoming unresponsive.

Resolution

FIX:
The fix is expected in a new firmware version. Updates to this article are expected with the fix details once available.

Workaround:
Restarting the management service on one of the controllers can help to access the Web user interface. This action does not impact production. 

Open an SSH session to the PowerVault controller management interface and run the following command: 

restart mc full

Additional Information

  • If the issue occurs even after MR4 or MR4+ update, and you have access to the array using FTP, try to capture support logs before restarting MC service.
  • If the log collection is not working, you must collect the logs immediately after restarting MC service.
  • Check if the user is using any security scanner to scan the array for vulnerability, if so, get the scanner name and version details.
  • Check if the user array is monitored with any monitoring tool and get the monitoring tool name and version details.
