Force Disable Module

Overview

When there is a component which cannot be isolated from the storage system in a normal way, this function forces the component to be isolated from the storage system (called "force disable" hereinafter).

This function is used when preparing a component to be removed from the storage system using the hot maintenance or hot preventive maintenance functions, and the status of the component cannot be changed to normal. If the component is installed in the storage system, this function can be performed, irrespective of the status.

Caution

Force disable can be performed only on one component at a time.
Not all components can be forcibly disabled by using this function. Refer to the following tables for the availability of force disable for each part.
This function cannot be used under the following conditions:
- The selected drive is in the "Broken" or "Not Supported" state
- A component (other than a drive) whose state is "Undefined" is selected
- One CM is in error status and the other CM is selected on a 2CM model

Operating Procedures

Select the component to perform the force disable on, and click [Force Disable] in [Action].
→ A confirmation screen appears.
Caution
- When there is a component which can be affected by force disable, a message to that effect is displayed. Check the component which might be affected.
Click the [OK] button.
→ The operations to be started and the displayed screen vary depending on the conditions as follows.
- When the Main CM can be affected by the force disable
  
  → The Main CM is switched, and the [Test Connection] Screen appears. Proceed to Step 3.
- When the Main CM cannot be affected by the force disable
  
  → Isolation of the target component starts. Proceed to Step 6.
Follow the displayed procedure to confirm that the new Main CM is connected to a LAN.
After confirming the connection, click the [Test Connection] button.

→ The [Test Connection Result] Screen appears.
Confirm the connection status check result, and click the [Resume Processing] button.
→ Isolation of the target component starts.
Caution
- If the connection of the new Main CM and the LAN fails, check the connection status again and return to Step 4.
Click the [Done] button to return to the screen when the target component was selected in Step 1.
