Version 5.2.1b Effective date June 2007 Description Fabric OS 5.2.1b contains enhancements and fixes since the release of Fabric OS 5.2.0b. These Release Notes add support for a new HP StorageWorks platform (the 4/32B SAN Switch), and for the iSCSI Director Blade (FC4-16IP). Update recommendations HP strongly recommends that users upgrade to Fabric OS 5.2.1b as soon as possible. Install Fabric OS 5.2.1b before installing the latest released port and intelligent blades.
New support for embedded switch models Fabric OS 5.2.1b supports the merge of the Fabric OS 5.0.x code stream with the Fabric OS 5.2.x code stream. This adds support for the following embedded switches: • Brocade 4Gb SAN Switch for HP p-Class BladeSystem (Brocade 4012) • Brocade 4Gb SAN Switch for HP c-Class BladeSystem (Brocade 4024) NOTE: The Fabric OS 5.0.5 stream remains active for the Core Switch 2/64 and for the SAN Director 2/128 in chassis modes 3 and 4.
Access Gateway allows a switch to operate in a special agmode that allows simplified connectivity between large numbers of servers and the SAN. Access Gateway leverages NPIV (N_port ID virtualization) to hide the complexity of the servers (both physical and virtual) attached to it while allowing easy SAN connectivity. The edge fabric switch provides all the fabric services while Access Gateway connects to the edge switch by what appears as a Host Bus Adapter (HBA) connection.
Management • Role-Based Access Control (RBAC) adds support for the new RBAC roles: Operator, Zone Manager, Fabric Administrator, and Basic Switch Administrator. • Virtual fabrics through administrative domains (Admin Domains or AD) provides data, management, and fault isolation through administrative domains. • DHCP support for B-Series switches.
Enabling or disabling DHCP To enable or disable this feature: 1. Log in with the following default values: • username admin • password password 2. Issue the ipaddrset command. Using External DHCP to set the Ethernet IP address NOTE: This procedure applies to c-Class only. To set the Ethernet IP address via DHCP: 1. Connect to the active OA via a web browser. 2. Document the DHCP-assigned address by selecting the switch from the GUI Rack Overview window. 3.

CAUTION: Install port blades like the HP StorageWorks 4/48 SAN Director Blade (FC4–48) only after upgrading to Fabric OS 5.2.0a or later. HP does not support directly upgrading from more than two previous releases. For example, upgrading from Fabric OS 5.0.x to 5.2.1b is supported, but upgrading from Fabric OS 4.4.0 or a previous release directly to 5.2.1b is not. Upgrading a switch from Fabric OS 4.4.0 or a previous release to 5.2.1b requires a two-step process: first upgrade to Fabric OS 5.0.x or 5.1.
PKI certification If you have purchased and are running the Secure Fabric OS option, go to the following web site for information on obtaining a PKI certificate: http://www.hp.com/storage/go/secureos. Important notes Table 2 provides information relevant to the release of Fabric OS 5.2.1b. Table 2 Important release information Topic FICON support Description With this release, the Switch Connection Control high integrity requirement for cascading FICON is available in the standard base Fabric OS.
FC4–48 port blade for the 4/256 SAN Director • The HP StorageWorks 4/48 SAN Director blade requires a minimum of Fabric OS 5.2.0a. Do not insert the FC4–48 blade into the 4/256 chassis until the chassis is running Fabric OS 5.2.0a or later. After Fabric OS has been updated and an FC4–48 has been installed, the Fabric OS will not be able to be downgraded earlier than 5.2.0a until the FC4–48 is removed. • The FC4–48 blade supports only core PID (fmt 1) in Secure Fabric OS.
Firmware upgrade/ downgrade • When upgrading from Fabric OS 5.1.0x to 5.2.0x, if there are two or more inter-fabric links (IFLs) connected to an edge fabric, one IFL will stay online and the other IFLs will go online and offline. This will cause a temporary traffic disruption going from multiple IFLs to one IFL and then back to multiple IFLs. This is due to the new front domain consolidation feature in Fabric OS 5.2.0, where the IFLs connected to the same edge share the same front domain.
IPSec for B-Series MP Router Blade (FR4–18i) • IPSec implementation details: • Pre-shared key • Main mode (IKE negotiation protocol) • Tunnel mode in Encapsulating Security Payload (ESP) • IPSec specific statistics not provided. • No NAT or IPV6 support • FastWrite and Tape Pipelining will not be supported in conjunction with secure tunnels. • Jumbo frames will not be supported on secure tunnels. • ICMP redirect is not supported for IPSec-enabled tunnels.
FCIP • Frame drops observed on FCIP slow links: • The frame drops occur when the FCIP tunnel bandwidth is set to 10 Base-T (10Mbps), E1 (1.048Mbps), or T1 (1.544Mbps). • With E1 or T1, frames are dropped even without an impaired link. • With 10 Base-T, frame drops may be observed when a low impairment is put to the link. • The portperfshow command indicated incorrect (smaller) bidirectional throughput on the FCIP tunnel when Fastwrite/Tape Pipelining is enabled.
portcfgdefault command function change for the Brocade 4Gb SAN Switch for HP c-Class BladeSystem With Fabric OS 5.2.1b, the portcfgdefault command now resets the configuration to HP factory default port settings. Update to Brocade 4Gb SAN Switch for HP c-Class BladeSystem 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.
SNMP configuration set via agtcfgset command can sometimes be initialized back to default when upgrading from one firmware version to another. Unlikely user scenario Fixed per Fabric OS 5.2.1. E-port offline transition caused fabric reconfiguration after firmware download on 2/32 switch in 2560 port fabric. Encountered under specific test conditions. Unlikely user scenario Fixed per Fabric OS 5.2.1 Running continuous portshow command loop hangs telnet session. Fixed per Fabric OS 5.2.1.
When using SMIAgent to connect to a switch in a larger fabric that contains more than 383 FDMI devices, the LoginAsUser fails and the switch panics; it either reboots or does HAfailover depending on platform. Fixed per Fabric OS 5.2.1. Removing a switch from a fabric causes trace files on remote switches to generate error message. Only applies to switches running 5.2.0x. Fixed per Fabric OS 5.2.1.
If failover occurs while FC4-48 blades being slotpoweron, some E-ports and unused ports may get stuck at Mod_Val state. Fixed per Fabric OS 5.2.1. Core file ffc_data is generated after disable/enable switch. Fixed per Fabric OS 5.2.1. swNbEntry under swFabric omits display of trunked EX-port ISLs. Fixed per Fabric OS 5.2.1. After configdownload and reboot, portshow displays FCIP tunnel for an IPIF that does not exist on the GE. Fixed per Fabric OS 5.2.1.
Non-disruptive configdownload may fail if invalid threshold alarm filter is used, due to invalid value. Fixed per Fabric OS 5.2.1. On 4/256, moving the switch PID to 2, waiting for the fabric to stabilize, and then issuing hafailover causes an assert on the new active CP. Fixed per Fabric OS 5.2.1. Redundant message about EX port trunking resulted from checking system settings for firmwaredownload Fabric OS 5.2.0 to 5.1.0d. Fixed per Fabric OS 5.2.1.
Fabric OS 5.2.1a fixes Table 4 lists defects closed in this Fabric OS 5.2.1a firmware release. Table 4 Fabric OS 5.2.1a fixes Closed defect summary Solution When run as a separate command from the CLI, diagclearerror may hang the console or cause the system to crash. Affects only the Brocade 4Gb SAN Switch for HP c-Class BladeSystem platform. Fixed per Fabric OS 5.21a. Fabric OS 5.2.1b fixes Table 5 lists defects closed in this Fabric 5.2.1b firmware release Table 5 Fabric OS 5.2.
