When it comes to the Dell PowerScale F200 node, customers are allowed to replace certain components classified as Customer Replaceable Units (CRUs). The components that customers can replace on the F200 node include:
* A. System Battery
* B. Network Interface Card (NIC)
* D. DIMM (Memory Modules)
* Customer Replaceable Units (CRUs):
* CRUs are components that customers can replace themselves without the need for a Dell technician.
* Replacing CRUs allows for quicker resolution of hardware issues and reduces system downtime.
* Components Customers Can Replace on F200:
* System Battery:
* The system battery, often a CMOS battery, maintains the system's BIOS settings when the node is powered off.
* It's a CRU because it's easily accessible and can be replaced without specialized tools or training.

In the output of the isi devices drive list command shown in the exhibit, the drive in location C1 is marked as
"USED," with the serial number VRKL242P. This indicates that the drive has been replaced but has not yet been initialized or formatted for use within the PowerScale cluster.
To make the drive usable, it must be formatted. The correct procedure to follow is to use the isi devices drive format command, specifying the drive location (C1 in this case). This will prepare the drive for use in the cluster, ensuring that it is recognized and available for OneFS to start writing data to it.
Steps to format the drive:
* Log in to the OneFS cluster using an SSH session with an account that has the necessary privileges.
* Run the following command to format the new drive:
bash
Copy code
isi devices drive format C1
This command will format the drive located at C1, making it available for use in the cluster.
* After the format is complete, verify that the drive is now in a HEALTHY state by running:
isi devices drive list
This should display the new status of the drive as HEALTHY, indicating that it has been successfully formatted and is ready for data operations.
This process is outlined in Dell's PowerScale Administration Guide and ensures the correct initialization of new or replaced drives.
