Prerequisites for Upgrading or Restoring Firmware Note: SAN Switch 2/32 products require firmware Version 4.0.2b or higher. Version 4.0.2b firmware and future upgrades are available on the HP website at: http://h18006.www1.hp.com/products/storageworks/fcsanswitch232/index.html Prerequisites for Upgrading or Restoring Firmware Read this section before upgrading/restoring switch firmware.
Firmware Upgrade Procedures Firmware Upgrade Procedures UNIX environments Use the following procedure to upgrade the SAN Switch 2/32 to firmware Version 4.0.2b in UNIX environments: 1. Download the firmware from the hp website into a Windows or UNIX machine. 2. Unzip the firmware zip file. It will create several files and folders. 3. Verify that the FTP service is running on the UNIX or Windows machine. 4.
Firmware Upgrade Procedures 7. Reissue the haShow command from the switch IP session, as follows: ter1_127:admin> haShow Local CP (Slot 6, CP0): Active. Remote CP (Slot 5, CP1): Non-Redundant ?This says the standby CP is still rebooting. ter1_127:admin> haShow Local CP (Slot 6, CP0): Active Remote CP (Slot 5, CP1): Standby <- Standby CP has completed rebooting and ready to become the active CP. HA Enabled, Heartbeat Up 8. From the switch IP address issue the haFailover command.
Firmware Upgrade Procedures second haFailover command after doing the second firmwareDownload, since the two CP cards are equivalent, and it makes no difference which is active and which is standby. OpenVMS Environments Use the following procedure to upgrade the SAN Switch 2/32 to firmware Version 4.0.2b in OpenVMS environments: Note: Do not use an OpenVMS machine as the FTP server without modifying the filenames and the script. OpenVMS uses periods for subdirectories instead of forward slash.

Firmware Enhancements Error Log Enhancements The Error Log subsystem now retains a maximum of 1,536 messages in RAM, that is, a total of 256 messages for each error message level (Panic, Critical, Error, Warning, Info, and Debug). In addition, important messages are stored in a separate persistent error log to guarantee that they are not lost in case of power outage or system reboot. Note: The enhancement prevents messages of lesser severity from overwriting messages of greater severity.
Firmware Enhancements Note: Within Web Tools, the Fabric View Events ICON window does not separate persistent from RAM error messages. Please use the Events ICON located on the SAN Switch 2/32 for additional log details. New Persistent Error Logging Commands Three Fabric OS commands were modified and four new commands added for the persistent error logging functionality. For more information, refer to the HP StorageWorks Fabric OS Version 3.0.x/4.0.x Reference Guide.
Firmware Enhancements portcfglongdistance Extended links in the same SAN are either 1 Gbps or 2 Gbps, but not both. If you have 1 Gbps extended links in the SAN you can not add a 2 Gbps Extended Link to the same SAN. Enhancement A new parameter was added to this command. The new syntax is as follows: portCfgLongDistance [slot/]port[, distance_level][, linkinitmode] linkinitmode Operand The linkinitmode operand applies to long distance setup only. It does not affect a normal link.
Fabric OS Commands Version 4.0.2b. Fabric OS Version 4.0.2b and all subsequent versions include the most current patch level of v15.3.1.4 of the SNMP Research agent, which SNMP Research has indicated is not susceptible to the vulnerability described in notes VU#854306 and VU#107186. ■ SNMP trap recipients have been linked to the Access Control List (ACL).
Fabric OS Commands Note: It is recommended that you only use these commands from the serial console port. Example 1: To advertise all modes of operation, follow this scenario for the ifModeSet command: Are you sure you really want to do this? (yes, y, no, n): [no] y Proceed with caution.
Fabric OS Commands Fabric Watch Daemon Startup During a switch startup or switch reboot, the Fabric Watch daemon is one of the last processes to become active. Depending on the size of the fabric, Fabric Watch may take several minutes to complete its start up sequence. Before Fabric Watch is completely active, it will not be able to monitor events occurring in the fabric. During this time, the switchStatusPolicyShow command will show the default settings instead of any custom settings.
Fabric OS Commands SNMP Commands The following SNMP commands are included with this release of firmware. loopporttest Command A new admin level command, loopporttest, has been added to this release. This command enables the administrator to perform a functional test of L_port M->M path on a loop.
Fabric OS Commands Note: You can specify a payload pattern to be used when executing this test. If the pattern is not specified, then at every 30 passes, a different data type is used to generate new pattern to create the frame. The data pattern will be generated base on each data type. Some data types may generate different data patterns on every pass. The data types are repeated every 210 pass.
Fabric OS Commands Diagnostics The following are possible error messages if failures are detected: DATA INIT PORT_DIED EPI1_STATUS_ERR ERR_STAT ERR_STATS ERR_STATS_2LONG ERR_STATS_BADEOF ERR_STATS_BADOS ERR_STATS_C3DISC ERR_STATS_CRC ERR_STATS_ENCIN ERR_STATS_ENCOUT ERR_STATS_TRUNC ERR_STAT_2LONG ERR_STAT_BADEOF ERR_STAT_BADOS ERR_STAT_C3DISC ERR_STAT_CRC ERR_STAT_ENCIN ERR_STAT_ENCOUT ERR_STAT_TRUNC FDET_PERR FINISH_MSG_ERR FTPRT_STATUS_ERR LESSN_STATUS_ERR MBUF_STATE_ERR MBUF_STATUS_ERR NO_SEGMENT PORT_

Fabric OS Commands Operands This command has the following operands: ■ slot-Specify the slot number in a Core Switch. The slot number must be followed by a slash ( / ) and the port number. The Core Switch has a total of ten slots counted from 1 to 10. Slot number 5 and 6 are Control Processor cards, and slot 1 - 4 and 7 - 10 are switch cards. On each switch card, there are sixteen ports counted from the bottom 0 to 15.
Fabric OS Commands portCfgLongDistance Command A new parameter was added to this command. The new syntax is as follows: portCfgLongDistance [slot/]port[, distance_level][, linkinitmode] linkinitmode Operand Only applies to long distance setup. It does not affect a normal link. It is added to ensure the long distance link initialization sequence. It is not required for long distance, but may be useful when initiating L1 and L2 links.
Fabric OS Commands For switches which have flash memory set into two equal partitions, the primary partition is the where the system boots from, the secondary partition is where a copy of the firmware is stored, in case the primary partition is damaged. To maintain the integrity of the firmware image in the flash memory, the firmwaredownload command does update both partitions at once. You must download the new firmware to the secondary partition of a CP.
Fabric OS Commands Example: switch12k:admin> firmwarecommit Doing firmwarecommit now. Please wait ... ........................................ ........................................ ........................................ ........................................ ........................................ ........................................ ...................... Replicating kernel image. ................................ FirmwareCommit completes successfully.
Fabric OS Commands ■ Implemented as a circular buffer. When more than maximum entries are added to the persistent log, old entries are over-written by new entries. ■ All error messages of levels Panic and Critical are automatically saved in the persistent log. ■ Guarantees that critical or panic level messages are not lost in the event of unexpected system reboot or failover.
Fabric OS Commands The output of the errDump command includes the display of errors/events history recorded in the persistent error log and error/events logged in the current run time cycle. This command also provides options to display ONLY those error/event messages that are saved in the persistent error log, or ONLY those messages generated during the current run time cycle.

Example Following example shows how to display current error log save level. switch:admin> errSaveLvlShow The following example shows how to display current error log save level on the Standby CP for switch 0.
Fabric OS Commands This parameter is required on the Standby CP. This parameter should not be used on the Active CP. You must follow -s with the switch instance number where the command is to be executed. Valid values for switch instance are 0 (for the switch instance associated with slots 1 though 4) or 1 (for the switch instance associated with slots 6 though 10). number_of_entries Specify the new persistent error log size in unit of number of error log entries.
Fabric OS Commands Operands This command has the following operands: s swinst - This is an optional parameter. It specifies a switch instance number. This parameter is required on the Standby CP. This parameter should not be used on the Active CP. You must follow -s with the switch instance number where the command is to be executed. Valid values for switch instance are 0 (for the switch instance associated with slots 1 though 4) or 1 (for the switch instance associated with slots 6 though 10).
Fabric OS Commands The syslogd is a process that runs on UNIX or Linux systems that reads and logs messages to the system console, log files, other machines and users as specified by its configuration file. Refer to the manual pages and related documentation for your particular UNIX host system for more information on the syslogd process and its capabilities. Note that the host system can be running UNIX, Linux or any other operating system as long as it supports standard syslogd functionality.
Fabric OS Commands Message Classification Syslogd messages are classified according to facility and priority (severity code). This enables a system administrator to take different actions depending on the error. The switch supports 6 message severity levels for error log messages. The following table provides a mapping between severity levels used by the switch and the syslogd severity levels supported by the UNIX system.
Fabric OS Commands To disable sending of error log messages to a previously enabled remote syslogd host do the following: 1. Login to the switch as Admin user. 2. At the command line enter the syslogdipremove command as follows: switch:admin>syslogdipremove “IP address of the remote syslogd host” 3. Verify the IP address was deleted using the syslogdipshow command.
Updating the Core Switch PID Format Command Summary ■ syslogdipadd—Add the IP address of the remote syslogd host to the switch. ■ syslogdipremove—Remove the IP address of the remote syslogd daemon. ■ syslogdipshow—Show the list of configured syslogd IP addresses. ■ errshow—Display messages from the error log on the switch. Updating the Core Switch PID Format Updating the Core Switch PID Format is necessary when upgrading an existing SAN to support larger port-count switches.
Updating the Core Switch PID Format Note: All switches running any version of Fabric OS 4.x are shipped with the Core Switch PID Format enabled, so it is not necessary to perform the PID format change on these switches. The actual process of changing the PID format is quite simple. Telnet into each switch in the fabric, and disable the switch using the switchDisable command.
Additional CLI commands Virtual Channel parameters (yes, y, no, n): [no] Switch Operating Mode (yes, y, no, n): [no] Zoning Operation parameters (yes, y, no, n): [no] RSCN Transmission Mode (yes, y, no, n): [no] Arbitrated Loop parameters (yes, y, no, n): [no] System services (yes, y, no, n): [no] Portlog events enable (yes, y, no, n): [no] Committing configuration...done. switch:admin> switchenable Use cfgEnable [active_zoning_config] on the switch to update zoning to use the new PID format.
Adding the SAN Switch 2/32 to an Existing Fabric Enhancement A new parameter was added to this command. The new syntax is as follows: portCfgLongDistance [slot/]port[, distance_level][, linkinitmode] linkinitmode Operand The linkinitmode operand applies to long distance setup only. It does not affect a normal link. It is added to ensure the long distance link initialization sequence. The linkinitmode operand is not required for long distance, but may be useful when initiating L1 and L2 links.
Adding the SAN Switch 2/32 to an Existing Fabric Note: The SAN Switch 2/32 is preconfigured with the Core PID format enabled. The existing fabric must also have this format enabled. The configure command is used to change the PID format on older switches. If the PID format is not consistent across the fabric, the fabric will segment. Refer to Appendix B in the HP StorageWorks SAN Switch 2/32 Installation Guide supplied with your switch for information on setting the Core PID format. 4.
