Grouping SAS IO Ports Using Fault Domains
Front-end ports are categorized into fault domains that identify allowed port movement when a controller reboots or a port fails.
Ports that belong to the same fault domain can fail over to each other because they have connectivity to the same resources.
NOTE: For user interface reference information, click Help.
Create a SAS Fault Domain
Create a SAS fault domain to group SAS ports for failover purposes on SC4020 controllers.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, right-click Fault Domains and select Create SAS Fault Domain.
4. In the Name eld, type a name for the fault domain.
5. In the Ports table, select the SAS ports to add to the fault domain.
When pairing SAS ports into the fault domain:
• Use one port from each controller.
• Make sure the paired ports have the same port number and are connected to the same server.
6. Click OK.
Delete a SAS Fault Domain
Delete a SAS fault domain if it is no longer needed.
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Fault Domains→ SAS, then select the fault domain.
4. In the right pane, click Delete. The Delete Fault Domain dialog box appears.
5. Click OK.
Managing Disks and Disk Folders
Manage disks by adding new disks and organizing disks in disk folders.
Add disks and enclosures to accommodate greater data needs. The supported number of enclosures attached to Storage Center
depends on the controller and enclosure being used.
When adding disks be aware of the following.
• After disks are added, additional space may not be immediately available. Make sure to allow enough time for Storage Manager to
allocate space for writes.
• Create a new disk folder only to address specic application program requirements. Creating a second disk folder may cause
storage to be used ineciently.
• Data cannot be written to unassigned disks.
• The Assigned disk folder was created during initial conguration of the Storage Center. Managing unassigned disks means
moving the disk to a managed disk folder.
• When Storage Manager detects self-encrypting drives (SEDs) that are Federal Information Processing Standard (FIPS) 140-2
certied, it formats the drives for Secure Data use.
– If Self-Encrypting Drives is licensed, Storage Manager can manage disks in a Secure Data folder.
– If Self-Encrypting Drives is not licensed, disks will be treated as unsecured drives, but may be upgraded to Secure Data status
if a license is purchased in the future.
