FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks Director Release Notes (AA-RTDVH-TE, August 2005)

Some IP addresses must be avoided

If you use HAFM to manage other M-Series Fabri c directors and edge switches, when

you select IP addresses for edge switches, directors, and for the HAFM appliance, do

not use IP addresses in the following range:

192.168.0.0 thro

ugh 192.168.0.255— This subnet is used internally to the HAFM

appliance. Using

an IP address 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 a nd cannot be disabled. All

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

will not see a change in fabric behavior unless you are using nonstandard HBAs. Hard

zoning improves security against intruders that load nonstandard HBA drivers.

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

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

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

your zone manag em ent practice, modify your documentation, or retrain Storage Area

Network (SAN) 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 blocked. 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 act ivations check box on the Conﬁgure Switch Parameters dialog b ox.

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

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

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

featu

re can be conﬁguredthroughHAFM,EWS,andCLI.

SNMP changes

Firmware 07.01.02-4 supports the following management information base (MIB)

versions on all products:

• Fabric Element MIB: 1.1

• MIB-II MIB: RFC-121 3 , non-implemented sections are not included
