Flag Description -g Displays the ASCII representation of unformatted error log entries. The output of this flag is in the following format: el_sequence Error log stamp number el_label Error label el_timestamp Error log entry time stamp el_crcid Unique cyclic-redundancy-check (CRC) error identifier el_machineid Machine ID variable el_nodeid Node ID variable el_class Error class el_type Error type el_resource Resource name el_rclass Resource class el_rtype Resource type el_vpd_ibm IBM vital product data (VPD) el_vpd_user User VPD el_in Location code of a device el_connwhere Hardware-connection ID (location on a specific device, such as slot number) et_label Error label et_class Error class et_type Error type et_desc Error description et_probcauses Probable causes et_usercauses User causes et_useraction User actions et_instcauses Installation causes et_instaction Installation actions et_failcauses Failure causes et_failaction Failure actions et_detail_length Detail-data field length et_detail_descid Detail-data identifiers et_detail_encode Description of detail-data input format et_logflg Log flag et_alertflg Alertable error flag et_reportflg Error report flag el_detail_length Detail-data input length el_detail_data Detail-data input -i File Uses the error log file specified by the file variable. If this flag is not specified, the value from the error log configuration database is used. 114 IBM ^ Certification Study Guide - AIX 5L Problem Determination Tools and Techniques
Flag Description -j ErrorID[,ErrorID] -k ErrorID[,ErrorID] -l SequenceNumb er Includes only the error log entries specified by the ErrorID (error identifier) variable. The ErrorID variables can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. When combined with the -t flag, entries are processed from the error-template repository. (Otherwise, entries are processed from the error-log repository.) Excludes the error log entries specified by the ErrorID variable. The ErrorID variables can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. When combined with the -t flag, entries are processed from the error-template repository. (Otherwise, entries are processed from the error-log repository.) Selects a unique error log entry specified by the SequenceNumber variable. This flag is used by methods in the error-notification object class. The SequenceNumber variable can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -m Machine Includes error log entries for the specified machine variable. The uname -m command returns the machine variable value. -n Node Includes error log entries for the specified node variable. The uname -n command returns the node variable value. -s StartDate Specifies all records posted after the StartDate variable, where the StartDate variable has the form mmddhhmmyy (month, day, hour, minute, and year). -t Processes the error record template repository instead of the error log. The -t flag can be used to view error record templates in report form. -y File Uses the error record template file specified by the file variable. When combined with the -t flag, entries are processed from the specified error template repository. (Otherwise, entries are processed from the error log repository, using the specified error template repository.) -z File Uses the error logging message catalog specified by the file variable. When combined with the -t flag, entries are processed from the error template repository. (Otherwise, entries are processed from the error log repository.) Chapter 6. Error reports 115
