Connecting to Attached Storage

Disk shelves can be added to standalone or clustered storage controllers without powering down the appliance or loss of service to clients. After connecting expansion storage, verify that you have redundant paths to each disk shelf.

To connect one or more disk shelves, use the diagrams in the Oracle ZFS Storage Appliance Cabling Guide, Release OS8.8.x.

When connecting SAS cables to two Oracle Storage Drive Enclosure DE3-12C disk shelves, cable tabs should be oriented downward toward the port's SAS logo for the top I/O Module (IOM A). For the bottom I/O Module (IOM B), cable tabs should be oriented upward toward the port's SAS logo.

Note:

Contact Oracle Service if you want to move a disk shelf between Oracle ZFS Storage Appliance systems. Certain limitations exist when importing storage pools, and can cause problems if not done properly by Oracle Service personnel.
