2 EMC VNXe3100/VNXe3150 — Replacing an Input/Output Module
Tasks to replace an I/O module
Task 1: Preparing the storage processor (SP) for service
To protect your VNXe system form accidental data loss while you replace an I/O module in
an SP, you must prepare the SP for service before you replace the I/O module. You prepare
an SP for service by putting it in Service mode.
1. Open Unisphere™ and select Settings, then Service System.
2. Log in with your service password.
3. In the System Components column, select the storage processor (SP A or SP B)
associated with the faulted component.
4. Under Service Actions, select Enter Service Mode, then Execute service action.
5. In the Service Confirmation dialog box click OK.
Putting an SP into Service mode takes about 10 minutes to complete. The storage
processor fault LED will flash alternating amber and blue while the SP remains in
Service mode and is receiving active power.
6. Wait until the SP fault LED is flashing alternating amber and blue before continuing to
the next task.
