Version 5.3.0a Effective date September 2007 Description Fabric OS 5.3.0a is a patch release that contains fixes since the release of Fabric OS 5.3.0. There is no new device support added with this release for HP StorageWorks platforms. Update recommendations HP strongly recommends that users upgrade to Fabric OS 5.3.0a as soon as possible. Install Fabric OS 5.3.0a before installing the latest released port and intelligent blades. Consider the following before upgrading: • If upgrading from Fabric OS 5.
Support for embedded switch models The B-Series embedded switches have transitioned from supporting the Fabric OS 5.0.5 stream only, to operating with Fabric OS 5.2.1b and later. The B-Series embedded switch models include: • 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.
New features in Fabric OS 5.3.0 This section lists Fabric OS 5.3.0 added features and improvements: NOTE: The Fabric OS 5.3.0a patch firmware contains the same features introduced in Fabric OS 5.3.0.
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. This architecture allows the deployment of many additional servers without requiring a domain and the associated fabric rebuild traffic that is prevalent when switches are powered on, or added, or removed from a fabric.
• MAC policies have now been replaced by IP filters, allowing configuration of acceptable IP addresses and ranges that may gain management access to the switch. • Protected-Extensible Authentication Protocol (P-EAP with MSCHAP-v2) support for RAdmin DomainIUS. • DH-CHAP now supported for authentication of HBAs and end-devices in addition to switches • Additional password security options • Lockout of Admin users that fail authorization.
Prerequisites Table 1 summarizes current Fabric OS firmware versions. These are the earliest recommended software versions that work together. However, HP recommends using the latest supported firmware release versions to get the greatest benefit from the SAN. For a list of retired products, visit the HP web site http://www.hp.com. Table 1 Current supported Fabric OS versions Model Earliest compatible version Recommended version HP StorageWorks 1 Gb Switch 2.6.2c 2.6.
Firmware upgrade instructions IMPORTANT: HP strongly recommends that users upgrade to Fabric OS 5.3.0a as soon as possible. To access the latest Fabric OS 5.3.0a firmware, configuration files, and MIB files, go to the following HP web site: http://www.hp.com/go/san. 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.
Important notes Table 2 provides information relevant to the release of Fabric OS 5.3.0a. Table 2 Important release information Topic Description 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. FICON support With release 5.2.
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 or 5.3.0, 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.
HA If there is an already segmented port and backbone devices are exported to an edge fabric, a build fabric/fabric reconfiguration can occur after running haFailover. Ensure that there are no segmented ports before upgrading firmware. 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.
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.
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 created 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.
Fabric OS 5.3.0 fixes Table 3 lists defects closed in the Fabric OS 5.3.0 firmware release. Table 3 Fabric OS 5.3.0 closed defects Closed defect summary Solution 4/256 Director running FICON with fsmode enabled & DLS on and port based route policy panics after upgrade from Fabric OS 5.0.x to 5.1.x or 5.2.0. Fixed per Fabric OS 5.3.0 Kernel Ops error when counter is overrun during stress to fail test. Fixed per Fabric OS 5.3.
FICON traps sent with wrong “Enterprise” value resulting in trap being processed as a swFault. Fixed per Fabric OS 5.3.0 In Web Tools customized port detail report, the report will be generated for all ports even if the user gives a particular port range as a filter. Fixed per Fabric OS 5.3.0 On 2Gb/s platforms, switch panic can occur if unstable or faulty port generates excessive number of interrupts. Fixed per Fabric OS 5.3.
In a FICON environment a Switch panic (in the Management Server daemon) could be seen if the switch receives one of three FICON specific frames (FICON GCAP, RLIR, RNID) and the fabric goes "unstable" (fabric being rebuilt such as when one of the switches in the fabric is powered off) before a response is sent. Fixed per Fabric OS 5.3.0 Traffic can’t be routed into backbone fabric from EX_port on 400 MP router with domain ID 7 or 12 and from FR4-18i blade in 4/256 with various domain ID’s.
Modifying port speed and trunking on FC4-48 ports from Web Tools, followed by HAfailover, and then trying to re-launch, Port Admin window on those same ports fails to reload Web Tools window. Fixed per Fabric OS 5.3.0 F_Port route cleanup doesn’t happen correctly when NPIV is used on switch in Access Gateway mode. Fixed per Fabric OS 5.3.0 EZSwitch Setup device display is overlapped in Display Connection window when window size not maximized. Fixed per Fabric OS 5.3.
Portstats: Selecting the “Show delta” radio button and clicking on the clear counter button, doesn’t clear the counters. It changes the values to negative. Clicking the clear counter button again will reset counter to zero. Fixed per Fabric OS 5.3.0 May see FFDC warning messages when manually changing switch IP address in DHCP network. Fixed per Fabric OS 5.3.
During stress testing, switch may report fabric busy following issuance of a long string of operations repeatedly. Fixed per Fabric OS 5.3.0 When using interactive mode to execute pathinfo, but with an invalid source port value, there is no error message. Fixed per Fabric OS 5.3.0 After receiving login reject on FC4-16IP, subsequent login attempts may fail intermittently under some conditions. This can be avoided by moving the session back to init state after rejecting a login. Fixed per Fabric OS 5.3.
Denial-of-Service condition affecting X.509 certificates verification (NISCC #729618) due to SSL vulnerability in OpenSSL. FOS 5.3.0 includes new version of OpenSSL that resolves this. Fixed per Fabric OS 5.3.0 Incorrect time in Web Tools Switch Health report. Fixed per Fabric OS 5.3.0 Incorrect F_Port behavior when RX side of the cable is disconnected, while the TX side is still inserted. Fixed per Fabric OS 5.3.
Fabric OS 5.3.0a fixes Table 4 lists defects closed in this Fabric OS 5.3.0a firmware release. Table 4 Fabric OS 5.3.0a closed defects Closed defect summary Solution Iswitchd panic occurred when doing data migration using DMM when invalid frame issued to the switch. Fixed per Fabric OS 5.3.0a. Diag failure caused FA4-18 to report a fault after continuously running CP failover test. Fixed per Fabric OS 5.3.0a.
