Service Action Allowed Light
Each drive CRU, power-fan CRU, and ESM CRU has a Service Action Allowed light. The
Service Action Allowed light lets you know when you can remove a customer
replaceable unit (CRU) with another component safely.
Caution: Potential loss of data access – Never remove a drive CRU, a power-fan CRU,
or an ESM CRU unless the Service Action Allowed light is turned on.
If a drive CRU, a power-fan CRU, or an ESM CRU fails and must be replaced, the amber
Fault light on that CRU turns on to indicate that service action is required. If there are no
data availability dependencies, or other conditions that dictate that a CRU should not be
removed, the Service Action Allowed light turns on. The Service Action Allowed light
automatically turns on or off as conditions change. In most cases, the Service Action
Allowed light turns on steadily when the Fault light is turned on for a CRU.
Moving the Enclosure
Before moving the enclosure to a new location or before removing the enclosure from its
rack, it is highly recommended that you first remove all drive sleds from the enclosure.
Doing so helps safeguard the equipment and ensures a smoother transition to the new
location. Before removing the drive sleds, label each one so that you can reinstall them in
the correct order.
Instructions for depopulating the enclosure are provided in Chapter 4, “Replacing
Enclosure Components”.
If you are removing an expansion enclosure so that you can connect it to a different
InfiniteStorage 4000 controller enclosure:
• Check with your service organization for appropriate software procedures that
allow moving the volume to the new RAID.
• Delete all volumes and hot spares from the drives before removing the unit.
• If you are moving the enclosure a significant distance (such as to another building
or city), it is recommended that you pack it in its original shipping container.
