If the enclosure does not initialize
It may take up to two minutes for all enclosures to initialize. If an enclosure does not initialize:
•
Power cycle the system
•
Make sure the power cord is properly connected, and check the power source to which it is connected
Stopping I/O
When troubleshooting disk drive and connectivity faults, stop I/O to the affected drives as a data
protection precaution. As an additional data protection precaution, it is helpful to conduct regularly
scheduled backups of your data.
When on-site, you can verify that there is no I/O activity by briefly monitoring the system LEDs.
