Important: When a SAS cable is inserted, ensure that the connector is oriented correctly
by confirming that the following conditions are met:
The pull tab must be below the connector.
Insert the connector gently until it clicks into place. If you feel resistance, the connector
is probably oriented the wrong way. Do not force it.
When the connector is inserted correctly, the connector can be removed only by pulling
the tab.
Cabling is done from the controller view top → down. Top/down button up is not
supported.

Drive replacement procedure
You can reseat or replace a failed drive in a Storwize V5000 Gen2 by removing it from its
enclosure and replacing it with the correct new drive without requiring the Directed
Maintenance Procedure to supervise the service action.
The system can automatically perform the drive hardware validation tests and can promote
the drive into the configuration if these tests pass, automatically configuring the inserted drive
as a spare. The status of the drive after the promotion can be recorded in the event log either
as an informational message or an error if a hardware failure occurs during the system action.
