FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks Edge Switch Release Notes (AA-RTDZH-TE, August 2005)

192.168.0.0 through 192.168.0.255—This subnet is used internally to the HAFM

appliance. Using an I P ad dress in this range causes the call-home feature to function

incorrectly.

Hard zoning

Hard zoning is a security enhancement introduced in ﬁrmware 05.01.00-24 that

prevents ports from accessing devices outside their zones. Hard zoning is enabled

by default when using ﬁrmware 05.01.00-24 or greater and cannot be disabled. All

HP-approved host bus adapters (HBAs) limit access to devices within their zones, so you

will not see a c

hange in fabric behavior unless you are using n onstandard HBAs. Ha rd

zoning improves security against intruders that load nonstandard H BA drivers.

Hard zoning is compatible with legacy zone deﬁnitions, including World Wide Name

(WWN) and por t zoning. You can use your existing zones and zone sets without any

changes. There are no changes to the zoning interfaces, so you do not need to modify

your zone managem ent practice, modify your documentation, or retrain Storage Area

Network (SA

N) administrators.

Hard zoning controls access at the ingress port. When a port attempts to send a frame

to a destination outside its zones, the frame is blo cked. A Class 2 frame is fabric

rejected, and a Class 3 frame is dropped.

Zoning change RSCN control

Normally, when a zone set is activated, a fabric format domain Register State Change

Notiﬁcation (RSCN) is sent to all devices in the fabric. With ﬁrmware 05.00.00 or later,

you can disable these RSCNs from being sent. This is done using the Suppress RSCNs

on zone set activations check box on the Con ﬁ gure Switch Parameters dialog box.

This feature signiﬁcantly changes the normal behavior of the fabric. Devices will have no

warning when zones change and will not automatically update their zoning information.

The ability to suppress RSCNs is disabled (check box is not selected) by default. This

feature can be conﬁguredthroughHAFM,EWS,andCLI.
