Version 5.2.0b Effective date February, 2007 Description Fabric OS 5.2.0b contains enhancements since the release of Fabric OS 5.2.0a and provides support for the following new hardware platform: HP StorageWorks 4/48 SAN Director Blade (FC4–48) for the 4/256 SAN Director IMPORTANT: You must upgrade to Fabric OS 5.2.0a or later before installing the HP StorageWorks 4/48 SAN Director Blade (FC4–48). Update recommendations HP strongly recommends that users upgrade to Fabric OS 5.2.0b as soon as possible.
Supported product models • • • • • • • • • • • • • HP StorageWorks 4/8 SAN Switch and 4/16 SAN Switch (SilkWorm 200E) HP StorageWorks 4/64 SAN Switch (SilkWorm 4900) HP StorageWorks 400 Multi-protocol Router (SilkWorm 7500) HP StorageWorks 16 Port 4Gb Blade (FC4–16) HP StorageWorks 32 Port 4Gb Blade (FC4–32) B-Series MP Router blade (SilkWorm FR4-18i blade) HP StorageWorks 4/48 SAN Director Blade (FC4–48) HP StorageWorks SAN Switch 2/8V (SilkWorm 3250) HP StorageWorks SAN Switch 2/16V (SilkWorm 3850) HP St
IMPORTANT: Any enhancements for the above models will be delivered in Fabric OS 3.2.x, Fabric OS 5.0.x and XPath OS 7.4.x sustaining releases. Devices supported See the HP StorageWorks SAN design reference guide for supported devices: http://www.hp.com/go/san. Operating systems See http://www.hp.com/go/san for a list of supported operating systems. Enhancements This section describes Fabric OS 5.2.0b new features.
• Port Mirroring—captures traffic between two devices for non-disruptive traffic analysis (available on the SAN Switch 4/32, 4/64 SAN Switch, 4/256 SAN Director, and 400 MP Router). 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.
• Long distance mode simplification: • LD is a dynamic distance mode that automatically discovers lengths and assigns the correct amount of buffer credits with an Extended Fabrics license. • LS is a static distance mode that allows you to specify the number of buffer credits required with an Extended Fabrics license. • LE supports up to 10 kilometers at any speed and does not require an Extended Fabrics license.
Fabric scalability Fabric OS 5.2.0b supports the same fabric scalability as Fabric OS 5.0.x and 5.1.x, that is, 2,560 ports with fifty domains. For FC Routing environments, refer to Table 1.
Prerequisites Table 2 summarizes current Fabric OS firmware versions. These are the earliest recommended software versions that work together. However, HP recommends using the latest supported software release versions to get the most benefit from the SAN. For a list of retired products, visit the following HP web site: http://www.hp.com Table 2 Current supported Fabric OS versions Model Earliest compatible version Recommended version HP StorageWorks 1Gb Switch 2.6.2c 2.6.
IMPORTANT: The B-Series MP Router blade (for use with the 4/256 Director only) must run Fabric OS 5.1.0b or later. Please note, the Core Switch 2/64 does not support the B-Series MP Router blade. Firmware upgrade instructions IMPORTANT: HP strongly recommends that users upgrade to Fabric OS 5.2.0b as soon as possible. See At startup — FC link connection shows G-Port status for details when update not recommended. To access the latest Fabric OS 5.2.
In addition, the following conditions must be met before upgrading to Fabric OS 5.2.0b: • Device-based routing must not be in use, otherwise the upgrade will fail. You can use the aptPolicy command to verify the routing policy. • Chassis configuration options 3 and 4 are no longer supported for the 4/256 SAN Director Additional notes on Fabric OS 5.2.0b firmware upgrade/downgrades include: • HP supports downgrading up to two previous releases, for example, if you upgrade to Fabric OS 5.2.0b from 5.0.
Fabric OS 5.2.0b updates The following sections list important updates. At startup — FC link connection shows G-Port status Under certain circumstances, with some switches running 5.2.0x (HP StorageWorks 4/8 or 4/16 SAN Switch, HP StorageWorks 4/32 SAN Switch, HP Storageworks 4/64 SAN Switch and HP StorageWorks 4/256 Director) connection to the SAN may not be established due to switch port showing G-Port status.
Refer to the Fabric OS Command Reference Guide for more information on how to use these commands: portcfgspeed 7,2 portcfgeport 7,0 portcfggport 7,1 This option can be used as a temporary workaround until a more permanent fix is available. Nevertheless, even after having defined these settings, it is recommended to verify proper connectivity after the controller restarts.
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 3 lists important information for Fabric OS 5.2.0b.
FC4–48 port blade for the 4/256 SAN Director • The HP StorageWorks 4/48 SAN Director blade requires FOS 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. After the FOS has been updated and a FC4-48 has been installed the FOS will not be able to be downgraded lower than 5.2.0a until the FC4–48 is removed. • The FC4–48 blade only supports core PID (fmt 1) in Secure FOS. • NPIV supported only in ports 0 to 15 of the FC4–48 blade.
• Users may install up to four FC4-16IP iSCSI blades per 4/256 SAN Director chassis, or any combination of up to four blades (FC4-16IP and B-Series MP Router blades, not exceeding the individual blade limit per chassis.
FC Routing • If an HP StorageWorks MP Router is present in the backbone fabric, the command fcrDisable may take up to 8 minutes to complete. If the MP Router is replaced by a B-Series MP Router blade (FR4-18i) or an HP StorageWorks 400 MP Router, the command completes immediately. • EX_Port trunking is not enabled by default. Security Remove any password enforced expiration of admin or root accounts before downgrading firmware to 5.0.1 or lower versions.
• User is not informed with the IPSec mismatch RAS event when configuring a tunnel with IPSec mismatch on either ends. 18 Fabric Merge Do not try to merge fabrics with conflicting domain IDs over a VE_Port. Before merging two fabrics over FC-IP with VE_Ports at each end, it is recommended that all domain ID and zoning conflicts are resolved. Scalability • Support for Default Zoning policies has been added to Fabric OS 5.1.0.
Fabric OS 5.2.0a fixes Table 4 lists defects closed in the Fabric OS 5.2.0a firmware release. Table 4 Fabric OS 5.2.0a closed defects Closed defect summary Solution Running a script that is repeatedly adding and removing LSAN zone failed when LSAN zone added to edge fabric zoning. Configuration does not propagate to both FCRs. Per Fabric OS 5.2.0a, the configuration now propagates correctly to both FCRs. Fabric OS 5.2.0b fixes Table 5 lists defects closed in this Fabric OS 5.2.0b firmware release.
Closed defect summary Solution ISCSI: unable to disable iSNS after peering with iSNS server. If not upgrading to Fabric OS 5.2.0b, the workaround is to issue the following commands. 1. Display the outstanding transaction: iscsicfg --show transaction 2. Abort transaction that is displayed in Step 1 above: iscsicfg --abort transaction -x ISCSI: host loses target with any IO when port is set to Error Recovery Level 2 (ERL2), digests enabled. If not upgrading to Fabric OS 5.2.
Closed defect summary Solution ISCSI: a command does not exist to report current iSNS status. Fixed per Fabric OS 5.2.0b On a SilkWorm 48000, the rtedebug cli returns error: REASON: ROUTE_ABSENT for a device connected to FC4-48 port blade. Fixed per Fabric OS 5.2.0b After extended stress testing with repeated slotpoweroff/on on two FC4-16IP blades, ICPD stopped by kSWD and switch CP failed over. Fixed per Fabric OS 5.2.
