HP StorageWorks Fabric OS 5.3.1a release notes (AA-RWEYJ-TE, May 2008)

Topic Description
Access Gateway Mode
Port State
When a disabled por t on a switch in Access Gateway mode is connected to
aconfigured loop HBA, the por t state alternates between Nosync and Insync.
The switchShow command displays the state of the remote HBA p or t 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 Gateway mode. There is no such restriction with
c-Class, since no servers require F ibre Channel Arbitrated Loop.
Access Gateway supports 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.

instructions.
After connecting to the Brocade 4Gb SAN Switch via the Onboard 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 Index, 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 cr eated unless all switches in the fabric are at
Fabric OS 5.2.0 or later versions. Once 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 World Wide Name
(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.
