Hewlett-Packard shall not be liable for errors contained herein or for incidental or consequential damages in connection with the furnishing, performance, or use of this material. This document contains proprietary information, which is protected by copyright. [. . . ] If fmsmode is disabled and a FICON CUP license is installed, no special action is required. Zoning and PDCM considerations The FICON PDCM controls whether communication between a pair of ports in the switch is prohibited or allowed. If there are any differences in restrictions set up with HP Advanced Zoning and PDCM, the most restrictive rules are applied. All FICON devices should be configured in a single zone using the Domain, Area notation. PDCM can then be used to allow or prohibit access between specific port pairs. PDCM persists across a failover because it is replicated at all times to the standby CP blade. The active PDCM configuration is saved to the IPL if the ASM bit is set on. Backing up and restoring configurations The Fabric OS configUpload command saves up to 16 FICON configuration files, including IPL files. For details on the behavior of the configDownload command, see "Restoring configurations in a FICON environment" on page 75. Troubleshooting The following sources provide useful problem-solving information: · The standard support commands (portLogDump, supportSave, supportShow) or the Fabric Manager Event Log By default, the FICON group in the supportShow output is disabled. To enable the capture of FICON data in the supportShow output, issue the supportshowcfgenable ficon command. After you get confirmation that the configuration has been updated, the following information is collected and appears in the output for the supportShow command: · ficoncupshow fmsmode · ficoncupshow modereg 116 Administering FICON fabrics · ficonDbg dump rnid · ficonDbg log · ficonShow ilir · ficonShow lirr · ficonShow rlir · ficonShow rnid · ficonShow switchrnid · ficucmd dump -A · Other detailed information for protocol-specific problems: · Display port data structures using the ptDataShow command. · Display port registers using the ptRegShow command. Identifying ports The ficonshow rlir command displays, among other information, a tag field for the switch port. You can use this tag to identify the port on which a FICON link incident occurred. The tag field is a concatenation of the switch domain ID and port number, in hexadecimal format. The following example shows a link incident for the switch port at domain ID 120, port 93 (785D in hexadecimal): switch:admin> ficonshow rlir { {Fmt Type PID Port Incident Count TS Format Time Stamp 0x18 F 785d00 93 1 Time server Thu Apr 22 09:13:32 2004 Port Status: Link not operational Link Failure Type: Loss of signal or synchronization Registered Port WWN Registered Node WWN 50:05:07:64:01:40:16:03 50:05:07:64:00:c1:69:ca Type number: 002064 Model number: 103 Manufacturer: IBM Plant of Manufacture: 02 Sequence Number: 0000000169CA tag: 155d Switch Port WWN Switch Node WWN 20:5d:00:60:69:80:45:7c 10:00:00:60:69:80:45:7c Type number: SLKWRM Model number: 24K Manufacturer: BRD Plant of Manufacture: CA Sequence Number: 000000000078 tag: 785d } } The Local RLIR database has 1 entry. switch:admin> ficonshow rlir Flag 0x10 Node Parameters 0x200115 Flag 0x00 Node Parameters 0x200a5d Fabric OS 5. x administrator guide 117 Backing up FICON files The FICON file access facility is used to store configuration files. Fabric OS saves the IPL and all other configuration files on the switch. A maximum of 16 configuration files, including the IPL file, are supported. You can upload the configuration files saved on the switch to a management workstation using the configUpload command. If the switch loses the configuration due to a hardware failure or filesystem error, use the configDownload command to restore previously uploaded configuration files. Because data uploaded using the configUpload command also contains the IPL, if Active=Saved mode is enabled, the switch ignores the IPL file downloaded via the configDownload command. Uploading the configuration files Issue the configUpload command. When you execute the configUpload command, all the files saved in the file access facility are uploaded to a management workstation. (There is a section in the uploaded configuration file labeled FICON_CUP that exists in an encoded format. ) Downloading configuration files with Active=Saved mode enabled Issue the configDownload command. The contents of existing files saved on the switch, which are also present in the FICON_CUP section, are overwritten. [. . . ] If your switch is not in a steady state when you issue the haReboot command, the switch performs a cold restart for the affected area, which can disrupt the ASIC and machine traffic. Your service provider may ask you to perform the single-CP blade procedure on HP StorageWorks SAN Directors if a CP blade fails and the replacement CP blade is running a version of firmware that cannot synchronize with the current active CP blade. For information about messages that might appear during the procedures, see the HP StorageWorks Fabric OS 5. x diagnostics and system error messages reference guide. Upgrading HP StorageWorks SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN Switch 4/32 Specify the -s option on the command line for single-CP mode. You are prompted for other options and can enable autocommit and autoreboot using the following procedure. [. . . ]
