New features in Fabric OS 5.3.0 This section lists Fabric OS 5.3.0 added features and improvements: NOTE: The Fabric OS 5.3.1b firmware release contains the same features introduced in Fabric OS 5.3.0. However, given that 5.3.1b is only supported on 2Gb switches, many of these listed 5.3.0 features, are not applicable to those switches.
Reliability, Availability, Serviceability (RAS) The RASLog is modified to support IPv6. RAS will also obsolete traceftp and savecore CLI and add its functionality to supportsave and supportftp. Management Fabric OS 5.3.0 added a new user role: the secAdmin or Security Administrator. This role maintains security administration, including logging and auditing. The addition of the secAdmin role allows users to isolate security management from complete Administrator management.
New Web Tools features in Fabric OS 5.3.0 Web Tools updates include: NOTE: Some Web Tools features listed are not applicable in this firmware release, as Fabric OS 5.3.1b is only supported on 2Gb switch models. • Usability enhancements • Web-started GUI • Revamped Switch Explorer • Single-signed application • Common GUI components with new search and export capabilities • “Advanced” vs.

Important notes Table 2 provides information relevant to the release. Table 2 Important release information Topic Description ipfilter command Starting with Fabric OS version 5.3.0, you can use the ipfilter command to block unauthorized Telnet access. The option to disable Telnet using the configure command is no longer available.
Topic Description Firmware upgrade/ downgrade • When upgrading from Fabric OS 5.1.x to 5.2.x or 5.3.x, if two or more inter-fabric links (IFLs) connect 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.
Topic Description 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 no segmented port exist before upgrading firmware. 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, HP recommends that all domain ID and zoning conflicts be resolved.
Topic Description Faulty SFPs External port with a faulty SFP will be disabled, then enabled once good SFP is inserted. However, port will still show as faulty even though it is healthy. To get the correct "healthy" indication, after enabling the port with the good SFP, remove and reinsert it and the port will then show as healthy.
Additional Fabric OS 5.3.0 enhancements Additional Fabric OS 5.3.0 enhancements include: • Provides new Fabric OS commands to rename an alias, a zone and a zone configuration. Zone –copy copies the zone object to a new zone object. Zoneobjectrename renames the zone object. • Detects and handles a corrupted zone configuration [under /etc/fabos/zone*] gracefully instead of rebooting. The switch also logs the error in RASLog. • Adds a new command that provides both the WWN and serial number of the switch.
Closed defect summary Solution New active CP got Oops and reboot during initialization after hafailover command issued. Fixed in Fabric OS 5.3.0 After CP reboot, VE tunnel does not come up due to GE0 port on FR4-18i stuck in No_Sync state when using copper SFPs. Fixed in Fabric OS 5.3.0 Switch does not generate RSCN following zoning changes using cfgEnable in interop mode, resulting in no PLOGI from hosts, and no target discovery. Fixed in Fabric OS 5.3.
Closed defect summary Solution With large zoneset (over 1200 zones) API library crashes as the zone library does memcpy that does not have terminating zero in the buffer. Fixed in Fabric OS 5.3.0 Change made in 5.2.0 to limit the number of FDISCs per unit of time, caused timeouts of NPIV logins in some BladeServer configurations with VC-FC. Fixed in Fabric OS 5.3.0. When FOS version prior to 5.2.0 is upgraded to a later version and the fabric.ops.mode.
Closed defect summary Solution Errlog (raslog) messages not available for diagnosing DHCP problems. Fixed in Fabric OS 5.3.0 Web Tools allows (switch,port) members to be added as member of a zone in interop mode, but this won’t actually be created successfully. Fixed in Fabric OS 5.3.0 by blocking addition of D,P members & D,P zoning when in interop mode.
Closed defect summary Solution Web Tools event filtering uses a time range of 0-11 rather than 1-12. In Web Tools Fabric Events and Events window, on invoking filter button and filtering based on “from” time or “to” time, on providing a time greater than 12 (e.g. 12:30 PM) will result in an error stating that time should be in range of 0-11. Fixed in Fabric OS 5.3.0 Additional Port Info column in FC Ports tab in Web Tools shows "None (FMS Mode)" instead of "Disabled (FMS Mode)." Fixed in Fabric OS 5.3.
Closed defect summary Solution Firmware downgrade to Fabric OS 5.1 or earlier is blocked even after ports 256 – 384 are removed from DCC policy created using [*] option. Currently have to delete DCC policy to avoid this. Fixed in Fabric OS 5.3.0 Admin user account with permissions to only Admin Domain 255 can create Admin Domains, but only Admin user accounts with permissions for all Admin Domains should be able to do this. Fixed in Fabric OS 5.3.
Closed defect summary Solution Host takes a long time to log in when disabled/unused GE-iSCSI ports have IP addresses configured to them. When host does a "SendTargets=All" those IP addresses will be in the list, but will be unreachable. Fixed in Fabric OS 5.3.0 After changing Backbone FID, switchshow does not display LE port information for some EX or VEX ports. Ports function correctly, only the display is incorrect. Fixed in Fabric OS 5.3.
Closed defect summary Solution When upgrading 4/256 to Fabric OS 5.2.0b from 5.2.0a, both ISL trunk connections to an edge switch connected to FC4-16IP were lost. Found in test lab and due to “lab mode” setting, not accessible to customers. Fixed in Fabric OS 5.3.0 Counter Address_err counting inappropriate data. Fixed in Fabric OS 5.3.0 When assigning IP address to a GE port with no cable connection, the FC4-16IP Blade incorrectly reports back to iSCSI initiator that port is valid.
Fabric OS 5.3.0a fixes Table 4 lists defects closed in the Fabric OS 5.3.0a firmware release. Table 4 Fabric OS 5.3.0a closed defects Closed defect summary Solution Iswitchd panic occurred during data migration with DMM when invalid frame issued to the switch. Fixed in Fabric OS 5.3.0a. Panic occurred on SAN Director 2/128 when running MS commands GPT/GPPN/GPS/GAPNL continuously. Fixed in Fabric OS 5.3.0a. When the 4/64 SAN Switch is constantly rebooted, the Name server crashed in rare conditions.
Fabric OS 5.3.0b fixes Table 5 lists defects closed in the Fabric OS 5.3.0b firmware release. Table 5 Fabric OS 5.3.0b closed defects Closed defect summary Solution With FC Tape Pipelining enabled on a 400 MP Router/MP Router Blade FCIP connection, data written to tape using a block size of greater than 128 KB will not be readable by some applications, causing backup to be unreadable.
Closed defect summary Solution When FRU in a 4/256 Director is inserted/removed a fruHistoryTrap should be generated, but is not. Fixed in Fabric OS 5.3.0c. Note that fruStatusChangeTrap will not be generated with FRU insert/remove. After upgrading switches to FOS 5.3.0, the Web Tools GUI bar showing the "Initializing Switch Details" will get stuck at 93% if the client’s regional and language settings are set to some non-US languages such as Dutch, Russian, and Greek.
Fabric OS 5.3.1 fixes Table 8 lists defects closed in the Fabric OS 5.3.1 firmware release. Table 8 Fabric OS 5.3.1 closed defects Closed defect summary Solution Management Server Daemon (MSD) panic occurs on switch during fabric initialization. When fabric hasn’t initialized its database during fabric initialization, MSD gets ipaddress of switches in fabric which could lead to memory corruption and cause MSD to panic. Fixed in Fabric OS 5.3.
When executing fastwrite with tape pipelining with a slow responding tape device, the switch sent improper frame causing tape job to fail. Ultimately, this caused the initiator to lose access to the tape drive. Fixed in Fabric OS 5.3.1 When FICON host sends PLOGI directly to a device immediately after registering with the Management Server, PLOGI may be rejected because the routing tables have not been established. Fixed in Fabric OS 5.3.
Fabric OS 5.3.1a fixes Table 9 lists defects closed in the Fabric OS 5.3.1a firmware release. Table 9 Fabric OS 5.3.1a closed defects Closed defect summary Solution F_Port link initialization failure caused by the switch not responding to NOS with OLS (continues to send idles). Fixed in Fabric OS 5.3.1a When downgrading from 6.0.0x to Fabric OS 5.3.0c, then 5.2.1b, then 5.0.5a, the switch can get into an endless reboot causing file system errors to be reported. Fixed in Fabric OS 5.3.
Fabric OS 5.3.1b fixes Table 10 lists defects closed in this Fabric OS 5.3.1b firmware release. Table 10 Fabric OS 5.3.1b closed defects Closed defect summary Solution An ipfilter --transabort command running in one Telnet session can be aborted from another Telnet session. Fixed in Fabric OS 5.3.1b Problems within an IP network could cause a switch running Fabric OS 5.3.x to panic. Fixed in Fabric OS 5.3.1b Workaround—Disable the clients trying to access evmd.
