DPI-1030: unable to get or set error structure for thread local storage

Problem:

flashgrid-cluster command was showing that diskgroups were not mounted, while diskgroup were successfully mounted on all nodes:

Reason:

GI was upgraded and Flashgrid was not able to reconnect ASM.

Solution:

Restart flashgrid_asm service, please note that it does not cause any downtime and is safe to run during business hours:

 # systemctl restart flashgrid_asm.service
