Adding a New Disk Shelf
![Caution Caution](graphics/caution.gif) | 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.
