Description Command
Graphs virtual disk read latency histograms for all LUNs or a specific WWN. This
command is available on the HSV200 series of controllers onward. vdrlg [lunwwn]
Displays virtual disk write latency histograms. This command is available on the HSV200
series of controllers onward. vdwl
Graphs virtual disk write latency histograms for all LUNS or a specific WWN. This
command is available on the HSV200 series of controllers onward. vdwlg [lunwwn]
Verifies array passwords for use with HP P6000 Performance Data Collector. vpw
Verifies whether HP P6000 Command View is accessible for state data collection. verifycvconfig
Command modifiers
Table 7 (page 84) lists the modifiers you can use in the command line interface. Modifiers must
be preceded by a minus sign (–). The modifiers are listed alphabetically.
When using Time Line Vizualizer (TLViz), only the -cont, -csv, -dur, and -ts2 command
modifiers are supported.
Table 7 HP P6000 Performance Data Collector command modifiers
Description Modifier
Substitutes contractions from the fnames.dict file. -cn
Runs an HP P6000 Performance Data Collector command continuously. You can specify
the interval by adding a number (n). Otherwise, the default interval is one second. Press
Ctrl+C to exit from this mode. -cont n
Displays data in comma-separated value (CSV) format and automatically includes a
timestamp. The timestamp format can be modified using the -ts1 or -ts2 modifiers. -csv
Specifies the duration of a continuous mode session. For example, if you enter evaperf
vd -csv -cont -dur 30
, virtual disk data is displayed in CSV format at one second
intervals for a total of 30 seconds.
-dur n
Displays data that contains the specified keywords. You must enter at least one keyword.
To enter multiple keywords, separate each keyword with a space. For example, if you -fd keyword
enter evaperf vd -fd test preliminary good, the data that displays contains
the words test, preliminary, and good.
Displays the WWNs, GroupId, DRMGroupId, and HostName along with their
corresponding friendly names. If friendly names are not configured a No FN message
is displayed in place of the friendly name. -fnid
Copies output to a file as well as displaying it in the command prompt. You can combine
this modifier with -cont and -dur for a fixed-time data capture. For example, if you -fo filename
enter evaperf vd -cont 5 -dur 30 -fo capture.log, virtual disk data is
displayed in CSV at five second intervals for a total of 30 seconds and is also written to
the capture.log file.
Limits virtual disk data collection to the specified virtual disks. You must enter at least one
virtual disk. You can also combine this modifier with -sz to limit data collection to the -fvdvdisk [vdisk]*
specified array(s). For example, if you enter evaperf vd -fvd test1 test2 -sz
server1
, data is collected for virtual disks test1 and test2 on array server1. You can
use this modifier with the vd, vdrl, vdwl, and vdts commands.
Displays output data in kilobytes per second (1,024). The default is megabytes per
second (1,000,000). -KB
Specifies that friendly names should not be used. -nfn
Specifies that no headings be included in CSV output. -nh
