Adding a New Disk Shelf
 | Caution - Improper orientation of mini-SAS HD cables during installation can damage the HBA connector and cause the HBA to malfunction. These cables are used with 4X4 port SAS-2 HBAs and 4X4 port SAS-3 HBAs. Position the release tab downward for horizontally mounted HBAs or to the right for vertically mounted HBAs. Mini-SAS HD active optical cables (AOCs) should be oriented similarly to copper cables.

Use the following procedure to add a new disk shelf to your system. Disk shelves can be added to standalone or clustered storage controllers without powering down the appliance or loss of service to clients. If the new disk shelf requires that other components be moved within the rack, you must move those components first. For disk shelf guidelines as well as cabling diagrams, see Getting Started with Cabling in Oracle ZFS Storage Appliance Cabling Guide .
- Stabilize the appliance rack. If your rack includes an anti-tip foot, extend it from the bottom of the rack.
- Install the new disk shelf into the rack, connect power cables, and supply power using the appropriate procedures in the Oracle ZFS Storage Appliance Installation Guide . For disk shelf placement guidelines, see Cabinet and Cabling Guidelines in Oracle ZFS Storage Appliance Cabling Guide .
- Working with a single disk shelf cable at a time, connect the cables to the controller(s) and other disk shelves using redundant paths and following the diagrams in the Oracle ZFS Storage Appliance Cabling Guide . Always retain one active path while cabling the new disk shelf.
- Verify that you have redundant paths to the disk shelf by examining the cabling.
- Verify the disk shelf presence by navigating to Maintenance > Hardware in the BUI, or by going to the CLI context maintenance hardware and issuing the command list.
- To add the new disk shelf to an existing or new pool, see Configuring Storage in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.0.
- If the storage workload is mostly read operations, it is recommended that you perform a backup and restore operation to quickly balance the workload across all disk shelves. To back up and restore user data, you can use NDMP backup software, snapshots, and/or remote replication. Accordingly, see NDMP Configuration in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.0, Snapshots and Clones in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.0, or Remote Replication in Oracle ZFS Storage Appliance Administration Guide, Release OS8.8.0.
