HP StorageWorks Fabric OS 5.3.0d Release Notes (AA-RWEYH-TE, December 2007)

Topic Description
Access Gateway Mode
Port State
When a disabled port on a switch in Access Gateway mode is connected to
aconfigured loop HBA, the port state alternates between Nosync and Insync.
The switchShow command displays the state of the remote HBA port that is
continuously attempting to reconnect to the disabled port.
Access Gateway mode is not suppor ted in the p-Class BladeSystem if there are
twohalf-heightservers(BL3xp)inthesamesleeve(ServerSlot1and9,or2and
10, etc). That configuration requires Fibre Channel Arbitrated Loop operation,
which conflicts with Access G ateway mode. There is no such restriction with
c-Class, since no servers require Fibre Channel Arbitrated Loop.
Access Gateway s upports only FCP initiator connections on the F_Ports. Note that
cascading Access Gateway devices or connecting FCP targets, loop devices, or
FICON channel/control units on the F_Ports are not supported.

After connecting to the Brocade 4Gb SAN Switch via the On board Administrator
(OA) connect command, you will be in the switch CLI prompt. To return to
the OA serial prompt:
• Type Exit to log out of the switch.
• Press Shift-Ctrl-underscore (escape sequence) to return to the OA prompt.
Zoning considerations
with FC4–48 Blade
B-Series switches running pre-5.2.0 firmware do not accept zone databases with
Domain, Port I ndex, references to ports higher than 255. Zoning in Fabric OS
5.2.0 and later, therefore, do not allow a Domain, Port Index entry for ports
above 255 to be created unless all switches in the fabric are at
Fabric OS 5.2.0 or later versions. O nce such an entry has been put into the zone
database, an attempt to connect a pre-Fabric OS 5.2.0 switch to the fabric results
in that switch being segmented with a Zone Mismatch segmentation reason.
Any zoning that is already in use can continue to be used. However, in Fabrics
containing pre-Fabric OS 5.2.0 switches, if new devices are added on the upper
16 ports (ports 32-47) of the FC4-48 port Blade, then WWN zoning has to
be used for those devices. If there is an existing Domain Port Index zone that
connects to ports 32–47, HP recommends that you transform just that zone to
WWN zoning. This would minimize the likelihood of rebuilding the entire fabric.
Fabrics containing only Fabric OS 5.2.0 and later switches have no zoning
limitation.
