Question
You have to perform a firmware update containing new code for DKCMain, CHBs and drives on a VSP G900.
What are two requirements? (Choose two.)
A. The CHBs must be updated first.
B. The Microprocessor utilization should be below 50%.
C. The Cache Write Pending rate should be below 30%.
D. There should be no sparing processes running in the background.
Answer
B. The Microprocessor utilization should be below 50%.
D. There should be no sparing processes running in the background.
Explanation
When performing a firmware update on a Hitachi VSP G900 storage system, two important requirements must be met:
- The microprocessor utilization should be below 50%. This ensures that the system has sufficient processing power available to handle the firmware update process smoothly, without causing any performance issues or disruptions.
- There should be no sparing processes running in the background. Sparing processes, such as disk drive rebuilds or copy back operations, can interfere with the firmware update process and potentially lead to complications. It is crucial to ensure that all background sparing processes are completed or suspended before initiating the firmware update.
It is important to note that the order of updating components (DKCMain, CHBs, and drives) is not a strict requirement, and the Cache Write Pending rate is not a critical factor in determining the readiness for a firmware update on the VSP G900.
