Table 3 Limitations with Advanced Web Tools Launch switch environment Problems Firmware: Fabric OS 3.1+ or 4.1+ Issue: When viewing the topology from Web Tools, if your initial login was a v3.1+ or v4.1+ switch and you view the topology from a switch with previous version of Fabric OS, there is no print function available in the Fabric Topology window. Operating System: any supported OS with a supported browser Browser: any supported browser on a supported OS Web Tools 3.1.0+ and 4.1.
Table 3 Limitations with Advanced Web Tools (continued) Launch switch environment Problems Firmware: version earlier than Fabric OS 2.6.2, 3.1.2, or 4.2.0 Operating System: any supported OS with a supported browser Issue: When trying to access a switch running firmware versions earlier than Fabric OS 2.6.2, 3.1.2, or 4.2.0 from the launch switch, Switch Explorer will display a null pointer exception and the SwitchInfo applet will not be displayed.
Table 4, Table 5, and Table 6 list important information for switches running Fabric OS 4.4.0b. Table 4 Information Specific to SAN Switch 4/32 SAN Switch 4/32 Description SWL and LWL SFP modules release mechanism The SAN Switch 4/32 uses an octal-style SFP cage that places SFPs in close proximity. As a result of the physical space limitation between the SFPs, HP requires the use of approved SFP modules only.
Table 4 Information Specific to SAN Switch 4/32 (continued) SAN Switch 4/32 Description Fan, RPM reading The RPM range can differ by as much as 1000 from fan to fan, which is within specifications. At the lowest RPM, the cooling specification is met; at the highest RPM, the acoustic specification is met. In other words, during normal operation, both the lowest and the highest observed fan speeds are within adequate margin of the acoustic and cooling specifications.
Table 5 Core Switch 2/64 Information Core Switch 2/64 Description Power supply requirements Customers reconfiguring SAN Director 2/128-only configurations by adding Core Switch 2/64 blades must ensure that all three power supply FRUs are installed, because Core Switch 2/64 blades have greater power requirements. Table 6 Fabric OS area information Fabric OS Area Description Compatibility Sometimes in a mixed fabric of Fabric OS 4.x, 3.x, and 2.
Table 6 Fabric OS area information (continued) Fabric OS Area Description Firmware download: boot ROM The boot ROM in Fabric OS 4.4.0 is automatically upgraded, by firmware download, to version 4.5.0 in all version 4.x switches. After it has upgraded, the boot ROM will not downgrade if a firmware downgrade is performed. This boot ROM version supports a redundant boot ROM capability and redundant boot environments in the SAN Switch 4/32. Firmware upgrade Fabric OS 4.
Table 6 Fabric OS area information (continued) Fabric OS Area Description Logging: Solaris syslogd local7 users When using the new syslogdFacility command to set the local7 level, if an even-numbered facility level is selected (for example, 0, 2, 4 or 6), all switch Critical system messages appear in the odd-numbered .emerg facility level file on the target Solaris systems: for example, local6.emerg will appear in local7.emerg if syslogd facility level 6 is selected.
Table 6 Fabric OS area information (continued) Fabric OS Area Description Security: error counter Telnet security errors that arrive in quick succession are recorded as a single violation by the telnet error counter. For example, a login error from a host whose IP address is 192.168.44.247 is logged as follows: Security violation: Login failure attempt via TELNET/SSH/RSH. IP Addr: 192.168.44.
Table 6 Fabric OS area information (continued) Fabric OS Area Description Security: PKICERT utility, installing certificates PKICERT 1.0.6 is the most current version of the PKICERT utility. When running the PKICERT utility to install switch certificates in a fabric that did not previously contain switch certificates and now includes a SAN Director 2/128, select the option to specify that certificates are installed only on those switches that do not currently contain certificates.
Table 6 Fabric OS area information (continued) Fabric OS Area Description Security: SLAP fail counter and two switches The SLAP counter is designed to work when all the switches in the fabric are in secure mode. All the switches in the fabric must be in secure mode for accurate SLAP statistics. Security: SSH login To properly connect SSH login, wait for secure mode to complete before rebooting or performing HA failover on the Core Switch 2/64 or SAN Director 2/128.
Table 6 Fabric OS area information (continued) Fabric OS Area Description WWN card FRU repair If an HA failover or power cycle occurs during a FRU replacement on the WWN card, the Core Switch 2/64 or SAN Director 2/128 becomes nonoperational. CAUTION: When performing a FRU replacement on a WWN card, complete the FRU procedure before attempting an HA failover or power cycling the chassis. Zoning Issue: Domain 0 in a zoning configuration file is invalid but has not been previously enforced.
Documentation updates This section provides information on last-minute additions and corrections to 4.x documentation. HP StorageWorks Fabric OS 4.x command reference guide, part number: AA-RVHVA-TE The following lists changes to the HP StorageWorks Fabric OS 4.x command reference guide. For example, the following commands are not supported in Fabric OS 4.4.
On page 223: Under fportTest, in the “Operands” section, replace the –seed and –width operand descriptions as follows: –seed payload_pattern Specify the pattern of the test packets payload. Valid values are: 0 CSPAT (default) 1 BYTE_LFST 2 CHALF_Sq 3 QUAD_NOT 4 CQRT_SQ 5 CRPAT 6 RANDOM –width pattern width Specify the width of the pattern that the user specified. When payload_pattern is set to 0x00, pattern_width is ignored.
HP StorageWorks Fabric OS 4.x MIB reference guide, part number: AA-RVHXA-TE On page 32, add the following section after Table 3: Firmware upgrades and enabled traps Prior to Fabric OS v4.4, traps were turned on and off as a group (for example, the SW-Trap, or FA-Trap). In these versions of the Fabric OS it was not possible to set individual traps (such as, swSensorStatusChangeTrap, swTrackChangesTrap, or connUnitEventTrap). In Fabric OS v4.
On page 132, the following text should be added to the “Creating and Modifying Zoning Configurations” section: When enabling a new zone configuration, you must ensure that the size of the configuration does not exceed the minimum size supported by all switches in the fabric. This is particularly important if and when you downgrade to a Fabric OS version that supports a smaller zone database than the current Fabric OS version.
The following row replaces the existing row, “State Changes,” in Table 26, “E_Port Class Threshold Defaults,” on page 96.

SAN Switch 2/8V, 2/16V, 2/16N, 4/32 installation guide, part number: AA-RVULC-TE On page 24, insert the following Important Note after step 1: IMPORTANT: Before installing a license key, you must insert transceivers in the ports to be activated. Remember to insert the transceivers in the lowest group of inactive port numbers first. For example, if only 16 ports are currently active and you are installing one 8-Port Upgrade license key, make sure to insert the transceivers in ports 16 through 23.
Core Switch 2/64 and SAN Director 2/128 installation guide, part number: AA-RVUSC-TE This section provides information on last-minute additions or corrections to the HP StorageWorks Core Switch 2/64 and SAN Director 2/128 installation guide, part number AA–RVUSC–TE. On page 45, insert the following “Powering off the switch” section: To power off the Core Switch 2/64: 1. Shut down both logical switches: a.
For details on the switchShutdown command, refer to the HP StorageWorks Fabric OS 4.x command reference guide. Power off the chassis by flipping both AC power switches to “0” (LEDs inside AC power switches should turn off). To maintain the ground connection, leave both power cords connected to the chassis and to an electrical outlet. On Page 110, add the following paragraph before the Note: A SAN Director 2/128 that is fully populated with FC2-16 blades can function on one power supply.
Replace Table 12 on page 76 with the following: Table12: WWN Bezel LED Patterns LED location and purpose LED Color 16-Port card/CP Steady green card Power Flashing green No light (LED is off) Status Recommended Action Power is OK No action required. Power to port card is OK; however, this LED flashes if the port card status LED is flashing. Check port card status LED and determine if it is flashing slow (2 second increments) or fast (1/2 second increments) and then take appropriate action.
Table12: WWN Bezel LED Patterns (continued) LED location and purpose LED Color Status Recommended Action NOTE: Check the individual port card (see Figure 15 on page 81) or CP card status LEDs (see Figure 16 on page 85) on the port side of the chassis to confirm the LED patterns. Power supply/ Power/Status Steady green Power is OK. No action required. Steady amber Power supply is faulty. Ensure that the correct AC power switch is on and the power supply is seated.
On page 136, Table 19, "Core Switch 2/64 and SAN Director 2/128 system specifications," replace the following table entry: "Switch latency <2.1 µsec any port to any port at 2 Gb/sec, cut-through routing" With this table entry: "Switch latency 2.05 < 2.35 µsec any port to any port at 2 Gbit/sec, cut-through routing" On page 56, under the heading "Configure IP Addresses for CP Cards," remove the first sentence in the Note: Use a block of three IP addresses that are consecutively numbered in the last octet.
