Question 2:
How can I verify if the control station is the primary?
Answer:
Type the /nasmcd/getreason command in CLI.
Question 3:
Users are able to access Unisphere using the primary control station IP address, why we can’t access Unisphere using the standby control station IP address?
Answer:
Unisphere and other management service are only running on the primary control station, so we are only able to access Unisphere using the primary control station IP address.
Question 4:
Does VNX provide uninterrupted file access to users when the control station is unavailable?
Answer:
The Control Station software, used to configure and manage VNX, operates independently of the file-access operations and services provided by Data Movers. If the control station fails, individuals Data Movers continue to respond to user requests and user access to data is uninterrupted.
Question 5:
After the problem that caused the failure is corrected on the control station 0, how can we return the primary standby Data Mover to their original states?
Answer:
There are two kinds of methods to return the primary standby Data Mover to their original states.
Method 1:
Type the following commands on the standby control station.
Method 2:
