HP StorageWorks 2.64 Director Switch - Manual (Page 94)

Configuring the director 94
Suppress Zoning 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 Zoning
RSCNs on zone set activations check box contains a check, 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 check
mark.
This option to suppress RCNs is disabled by default and, in most cases, should be disabled 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.
Director Speed (Director 2/64 only)
NOTE: To change this value, you must first set the director offline. Be sure to set the director back
online after you change this value.
When setting the director speed, consider the following:
• Configure port speeds individually through the Configure Ports dialog box. You cannot set a
director speed to less than the port speeds. If you set the director speed to
1 Gig
and at least
one port is configured at
2 Gig,
an error message displays stating that you cannot modify the
director speed.
• If you set the director data speed to
2 Gig
, all installed CTP cards must support 2 Gb/s data
speeds or an error message displays stating that you cannot modify the director speed.
• When you change the speed to
2 Gig
, all ports on Fibre Channel port module (FPM) cards go
to an inactive state. A warning/confirmation message also displays, allowing you to continue
the operation or cancel. Only universal port module (UPM) cards allow 1 Gb/s and 2 Gb/s
operation.
• Director firmware must support the 2 Gb/s data rate. If you set the speed to
2 Gig
and the
firmware only supports 1 Gb/s, an error message displays stating that the feature is not
supported and providing the firmware level that will support the higher speed.
At the Director Speed field, click 1 Gig or 2 Gig to select the speed of Fibre Channel operation.
NOTE: Changing the director speed to 2 Gb/s with any 1 Gb/s FPM card installed will cause the
following warning/confirmation message to display:
All FPM ports will be held
inactive while the director is configured to 2 Gb/sec speed. Do you want
to continue?
