Description
During a system shutdown using the NAS Manager, the system does
not stop and the controllers do not shutdown after 20 minutes.
Cause The system shutdown procedure is comprised of two
separate processes:
• Stopping the file system
• Powering down the PowerVault NX3500 controllers
The file system may take a long time to clean the cache to the
storage either due to lot of data, or due to an intermittent
connection to the storage.
During the powering down stage, the issue could be due to the OS
kernel hanging on the controller or failing to sync its state to the
local drive.
Workaround If the file system has stopped and if one of the controllers are still up,
you can physically power down the controller using the power button.
If file system has not stopped, you must let it continue working.
The file system reaches a 10 minute timeout, flushes its cache to
the local controllers, and continues the shutdown process.
