HP 3PAR OS 3.1.3 Command Line Interface Reference

–freq <minutes>
Specifies the interval, in minutes, that the command enters standby mode between iterations using
an integer greater than 0. If this option is not specified, the number of iterations is looped
indefinitely.
–vvlayout
Specifies that the layout of the virtual volume is displayed. If this option is not specified, the layout
of the virtual volume is not displayed.
–portstat
Specifies that statistics for all disk ports in the system are displayed. If this option is not specified,
statistics for ports are not displayed.
–pdstat
Specifies that statistics for all physical disks, rather than only those with high service times, are
displayed. If this option is not specified, statistics for all disks are not displayed.
–chstat
Specifies that chunklet statistics are displayed. If not specified, chunklet statistics are not displayed.
If this option is used with the –movech option, either on or force must be specified. See
“RESTRICTIONS” (page 650) for conditions on using the -chstat option.
–maxpd <number>
Specifies that only the indicated number of physical disks with high service times are displayed.
If this option is not specified, 10 PDs are displayed.
–movech auto|manual
Specifies that if any disks with unbalanced loads are detected that chunklets are moved from those
disks for load balancing.
auto
Specifies that the system chooses source and destination chunklets. If not specified, you are prompted
for selecting the source and destination chunklets.
manual
Specifies that the source and destination chunklets are manually entered.
SPECIFIERS
maxsvct <msec>|highest
Specifies that either the maximum service time threshold (<msec>) that is used to discover
overutilized physical disks, or the physical disks that have the highest maximum service times
(highest). If a threshold is specified, then any disk whose maximum service time exceeds the
specified threshold is considered a candidate for load balancing.
avgsvct <msec>|highest
Specifies that either the average service time threshold (<msec>) that is used to discover overutilized
physical disks, or the physical disks that have the highest average service time (highest). If a
threshold is specified, any disk whose average service time exceeds the specified threshold is
considered a candidate for load balancing.

• Access to all domains is required to run this command.
• This command requires a System Tuner license. Contact your local HP 3PAR representative
