Flag Description -F FlagList Selects error record templates according to the value of the Alert, Log, or Report field of the template. The FlagList variable can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. The -F flag is used with the -t flag only. Valid values of the FlagList variable include: alert=0, which selects error record templates with the Alert field set to False. alert=1, which selects error record templates with the Alert field set to True. log=0, which selects error-record templates with the Log field set to False. log=1, which selects error record templates with the Log field set to True. report=0, which selects error record templates with the Report field set to False. report=1, which selects error record templates with the Report field set to True. -J ErrorLabel Includes the error log entries specified by the ErrorLabel variable. The ErrorLabel variable values can be separated by commas, or enclosed in double-quotation marks and separated by commas or blanks. When combined with the -t flag, entries are processed from the error template repository. (Otherwise, entries are processed from the error log repository.) -K ErrorLabel Excludes the error log entries specified by the ErrorLabel variable. The ErrorLabel variable values can be separated by commas, or enclosed in double-quotation marks and separated by commas or blanks. When combined with the -t flag, entries are processed from the error template repository. (Otherwise, entries are processed from the error log repository). -N ResourceName List -R ResourceTypeLi st Generates a report of resource names specified by the ResourceNameList variable. For hardware errors, the ResourceNameList variable is a device name. For software errors, it is the name of the failing executable. The ResourceNameList variable can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. Generates a report of resource types specified by the ResourceTypeList variable. For hardware errors, the ResourceTypeList variable is a device type. For software errors, it is the LPP value. The ResourceTypeList variable can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. 116 IBM ^ Certification Study Guide - AIX 5L Problem Determination Tools and Techniques
