FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks HA-Fabric Manager Release Notes (AA-RUR6G-TE, August 2005)

Firmware 05.03.01-01 is available for the Edge Switch 2/24, and ﬁrmware

05.05.01-01isavailablefortheEdgeSwitch2/12.Theseversionsareinstalledonlyon

the Edge Switch 2 /24 and Edge Switch 2/12, and only when these switches are placed

in a M-Series SAN running 05.02.00 ﬁrmware. A copy of these versions of ﬁrmware,

are contained on the HP StorageWorks edge switch documentation and ﬁrmware CD

(Par t Number 524-000001-005).

Reinstalling feature licenses

Feature licenses (or keys) must be reinstalled after per forming a factory reset on a

director to regain use of the licensed features (e.g., SANtegrity Binding).

CTP controls port lights

Por t lights on the edge switch and director products are controlled by the CTP

functionality. Certain activities such as ﬁrmware updates, I PLing the CTP, or switching

over to the backup CTP (director) c an cause these port lights to extinguish m om entarily

until control is reasserted by the CTP. The actual Fibre Channel trafﬁcisnotaffected

during these times.

Allocation for ports

Firmware

07.00.00 or later, supports the ability to allocate a speciﬁcnumberofbuffer

credits per port. This feature provides beneﬁt primarily in the Edge Switch 2/12 and

2/24 switches, where a single pool of buffers is shared among all ports. Users will now

be able to allocate buffer credits only where needed. For the Director 2/64, Director

2/140, and Edge Switch 2 /32 switches, this enhancement sim ply allows m o re granular

conﬁguration options for users who want complete conﬁguration control.

NVRAM caching

All writes to non-volatile mem ory random access memory (NVR AM) , which stores

conﬁguration data, are now cached to prevent possible corruption of information. Prior

to ﬁrmware 07.00.00, a small window existed where a switch power-down during an

NVRAM write could enable the conﬁgu ration default settings when the switch is powered

back on. All switches and d irectors are now protected from potential interruptions to

NVRAM updates.

Robust large fabrics

Numerous low-level enhancements and optimizations have been made to improve the

ability of directors and switches in fabrics containing high po p ulations of devices.
