2.8.2 Ports
2.8.2.1 FC / SAS / SCSI ports
This shows information about FC/SAS/SCSI ports. For FC ports including Controller Failover Mode (for redundant
controller only), each port’s ID, name, WWN, Hard loop ID, connection mode (private loop, public loop, or point-to-point),
and data rate. For SAS ports including each port’s ID, name and SAS address. For SCSI ports including each port’s ID,
name, default SCSI ID and data rate. To change the settings, follow the instructions given below:
1. Select an FC/SAS/SCSI port and click Modify to open the configurations window.
2. Specify the following options.
3. Check the ‘Apply connection mode and data rate to all FC ports’ option if necessary.
Check the ‘Apply data rate to all SCSI ports’ option if necessary (SCSI port).
4. Click Apply and the ‘Restart to Apply’ prompt box appears. Click Restart to restart the controller immediately, or OK
to restart later.
5. All settings except FC/SAS/SCSI port name are effective after you reconnect the controller.
• Setting FC Worldwide Node Name
The default worldwide port name (WWPN) of each FC port should be different. The assignment of worldwide node names
(WWNN) to all FC ports help the RAID system recognize all the FC ports with the same WWPN as one device.
To set FC worldwide node name, click the WWNN button. Then select Distinct to use different FC WWPNs, or Identical
to synchronize all FC ports using the same WWNN. Click Apply to save. The WWPN of all FC ports will be synchronized
the next time you start the RAID system.
Note
In redundant-controller systems, the four FC ports are given identifiers fcpa1, fcpa2, fcpb1, and
fcpb2 to identify the corresponding port positions located on each controller.
Controller Failover
Mode
(For FC port with redundant controller only)
Multipath IO: This mode allows the host computer to access the RAID system over
multiple paths. To use this mode, Pathguard needs to be installed. See 5.1 Multi-
Path IO Solutions for more information.
Multiple-ID: This function requires the use of fiber switch. When you select this
function, only simple method is available for storage provisioning. See 5.2 Multiple
ID solutions for more information.
Name Type a name associated with each FC/SAS/SCSI port. The maximum name length
is 15 bytes. For SAS ports please jump to step 4 after setting name.
Hard Loop ID Select a fixed loop ID for each FC port from the drop-down menu. To disable hard
loop ID, select Auto. The loop ID is automatically determined during loop
initialization procedure.
Connection Mode Auto: The controller will determine the connection mode automatically.
Arbitration loop: This is a link that connects all the storages with the host, which
enables data transferring.
Fabric: This is a point to point connection mode without a switch.
Default SCSI ID (For SCSI port)
Select a fixed SCSI ID for each SCSI port from the drop-down menu. The ID range
is from 0 to 15.
Data Rate Auto / 1GB / 2GB / 4GB
Select a preferred data rate for an FC port or all FC ports.
(For SCSI port)
Async / Fast / Fastwide / Ultra / Ultrawide / Ultra2 / Ultra2wide / Ultra3 /
Ultra320
Select a preferred data rate for an SCSI port or all SCSI ports.The default setting is
Ultra320.
