• The customer had electrical interruption so the cluster was shut down because his UPS didn’t work.
• When turning up the device, they didn’t have access to the CIFS folders by network and couldn’t reach the console by ISM and ping.
• Tried to connected by CLI on the master node but in the output only shows alphanumeric characters.
• Connected by serial on the master node but they couldn’t access to the master/master account.
• Could access support/Symantec account and ran the commands
• Did a troubleshooting and found that the console was migrated to the slave node.
