71 Edge Switch 2/24 Installation Guide
Suppress RSCNs on zone set activations
Fabric format domain register for state change notifications (RSCNs) are sent to
ports on the switch following any change to the fabric's active zone set. These
changes include activating and deactivating the zone set, or enabling and
disabling the default zone. When the Suppress RSCNs on Zone Set Activations
check box is selected, fabric format RSCNs are not sent for zone changes to the
attached devices on the switch. Click the check box to remove or add a
checkmark.
This option is enabled (check box not selected) by default. In most cases this
option should be enabled so that attached devices can receive notification of
zoning changes in the fabric. However, some HBAs may log out, then log back
into the fabric when they receive an RSCN, thereby disrupting Fibre Channel
traffic. Consult with your HBA and storage device vendor to determine if
disabling this option (and thereby enabling RSCN transmission) will cause
problems with your HBA or storage products.
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 NV-RAM on the switch.
The switch must be offline to change parameters in this dialog box.
1. Ensure that the switch is set offline. For instructions, see “
Set the Switch
Offline ” on page 66.
Caution: Setting the switch offline terminates all Fibre Channel connections.
2. At the Hardware View, choose Operating Parameters > Fabric Parameters
from the Element Manager window. The Configure Fabric Parameters dialog
box displays (
Figure 19 ).
