Cable a New Drive Enclosure (Manual)

If you do not use Guided Maintenance to add a new Drive Enclosure, carefully follow the manual cabling sequences based on the Drive Enclosure number within the string. Work with your Oracle Sales Engineer and refer to the planning worksheet to determine the string assignments for each new Drive Enclosures.

Prerequisites:

The steps for planning the system expansion are complete.
The new Drive Enclosures are installed in the rack and powered on.
The cables are unpacked and you have the correct mini-SAS to mini-SAS cables and mini-SAS to mini-SAS HD cables for adding the Drive Enclosures to the system. Refer to your system expansion plan for details.

If the Oracle FS System remained in production for the Drive Enclosure add procedure, adding the second and third Drive Enclosure to a string requires the system to re-route I/O traffic around the connections that are temporarily disrupted. System connections are not interrupted when you add the first, fourth, and fifth Drive Enclosure to a string.

Note: If the system remained in production, continually be aware of the state of the system when adding Drive Enclosures. The configuration of the system has dual paths for all of the required connections within the system. During parts of the procedures for adding a Drive Enclosure, one of those paths might be disabled. An error such as disconnecting the wrong cable can cause serious problems to ongoing operation of the system.

Based on the planning worksheet defining the strings for the new Drive Enclosures, cable the new Drive Enclosures one at a time. Follow the procedure that corresponds with the Drive Enclosure number within the string.
