Zoning enhancement to reduce fabric congestion

In Homogeneous Fab

ric mode, an enhancement was added to reduce unnecessary

fabric congestio

n when performing fabric-wide zoning operations that impact the Default

Zone. This enhan

cement limits the number of members allowed in the Default Zone to

64. When the firmware detects a zoning operation that would cause the member count

in the Default Zone to exceed 64 (such as deactivating an active zone set that has mo re

than 64 members) , the operation is aborted and the user interface (HAFM 8.6 or EWS)

displays the following message: Zoning request denied: Operation will

cause the Defa

ult Zone to exceed its limit of 64 members.

NOTE:

This limit is d

isabled when the switch parameter Suppress Zoning RSCNs on Zone set

activations check box is enabled.

Kno wn issues

This section describes the known issues related to the Director 2/64 and Director 2/140.

HSG80 transparent mode not supported with IBM AIX

Use of an HSG80 with IBM AIX is restricted to operating the HSG80 in M u ltibus mode

with the Director 2/64 and Director 2/140. Transparent mode is not supported at

this time.

Workaroun

None.

HSG80 transparent mode not recommended with controller in SCSI-3 mo de

with HP-UX operating systems

Due to an issue with nonexistent duplicate LUNs being displayed with the HP-UX

operating systems, the HSG80 controller is restricted to SCSI-2 mode of operation

when set to Transparent failover mode.

SCSI-3 mode of operation in Multibus failover mode is fully supported with the use of

Secure

Pa th software, 3.0 or later versions.
