Configuring the Switch
Domain RSCNs
Domain register for state change notifications (domain RSCNs) are sent between end
devices in a fabric to provide additional connection information to host bus adapters
(HBA) and storage devices. As an example, this information might be that a logical
path has been broken because of a physical event, such as a fiber optic cable being
disconnected from a port. Consult with your HBA and storage device vendor to
determine if enabling Domain RSCNs will cause problems with your HBA or storage
products. Note that this option is required if Enterprise Fabric mode (optional
SANtegrity feature) is enabled. Refer to Domain RSCNs on page 6-14 for details.
Operating Mode
NOTE: To change this value, you must first set the Switch offline. Choose Set Online State
from the Maintenance menu to display the Set Online State dialog box, then click the Set
Offline button. Be sure to set the Switch back online after you change this value.
Click either the S/390 or Open Systems radio buttons:
• If the FICON Management Server feature is enabled, the default mode will be
S/390. The operating mode cannot be changed to Open Systems with the FICON
Management Server feature enabled. Typically, S/390 mode is used when
attaching an IBM S/390 Parallel Enterprise or zSeries server to the Switch and
implementing inband Switch management through a Fibre Connection (FICON)
channel.
•Use Open Systems mode for all other (non-FICON) Fibre channel environments.
Configure Fabric Operating Parameters
Use procedures in this section to set parameters on the Switch for fabric operation
through the Configure Fabric Parameters dialog box. These operating parameters
are stored in NVRAM on the Switch.
1. The Switch must be offline to change parameters in this dialog box. If it is not and
you activate values, a dialog box displays prompting you to set the unit offline.
CAUTION: Setting the Switch offline terminates all Fibre Channel connections.
To set the unit offline:
a. Choose Maintenance > Set Online State from the Product Manager
window. The Set Online State dialog box displays.
