current directory. The names of the output files follow the naming convention for statistic
information files (See Remark). A file name indicates the disk array name from which statistic
information is collected and the date (or month) of collection. If the file with the same name exists,
the file is overwritten.
iSMprfarc automatically switches between summarizing processes depending on the type of the
specified file.
If a statistic information history file is specified as an input file, iSMprfarc performs primary
summarizing and outputs a primary summarized file. The name of the output file consists of string
indicating the disk array name and date of collection with the extension of the summarized file. You
can specify multiple statistic information history files for different disk arrays with different collection
dates. In this case, each file is summarized separately and a primary summarized file is created
respectively.
If a primary summarized file is specified as an input file, iSMprfarc performs secondary summarizing
and outputs a statistic information secondary summarized file. Basically, you need to specify primary
summarized files for one month which have a name indicating the same disk array and collection dates
in the same month. If the files are for less than one month, the specified files are summarized. The
name of the output file consists of string indicating the disk array name and month of collection
(collection dates of the files minus days) with the extension of the summarized file. You can specify
multiple primary summarized files for different disk arrays or primary summarized files on collection
dates in different months mixed together. In this case, summarizing is performed for each disk array
and for each collection month, and a statistic information secondary summarized file is created
respectively.
If a statistic information history file is specified as an input file with the -d option, iSMprfarc performs
direct secondary summarizing. It creates a statistic information secondary summarized file from a set
of statistic information history files for one month which have a name indicating the same disk array
and collection dates in the same month. The file output conditions are the same as secondary
summarizing described above. If a primary summarized file is specified with the -d option, the
operation is the same as the normal secondary summarizing.
The -o option changes the destination of files to the directory specified in the argument.
Statistic information history files and primary summarized files cannot be mixed. If they are mixed,
an error occurs.
With Windows, you cannot use wildcard (e.g. * and ?) in a file name. To specify a file name with
spaces, enclose it in double quotation marks.
(ii)
Period Specification
If the input/output directory (the -p option), unit of summarizing (the -hour or -day option), and target
period of summarizing (argument of the -hour or -day option) are specified, iSMprfarc summarizes in
the Period Specification Mode. They are mandatory options and cannot be omitted.
