measure rec-round-trip-time

After setting up the REC path information, the round trip times to all remote storage systems where a time
has not yet been set must be measured. This command measures the round trip time for each REC path,
displays it, and can also save it in the system if so desired.
• If the round trip time is measured with "-mode auto" specified, the path multiplicity is automatically set
to the recommended multiplicity.
• If the round trip time is measured with "-mode manual" specified, the path multiplicity is automatically
changed to the recommended multiplicity only if the results are saved to the system.
■ Syntax
measure rec-round-trip-time -mode {auto | manual}
[-remote-boxid

remote_storage_system_box_id
This parameter specifies the round trip time measurement and the setting mode.
auto Automatic mode. Round trip times are measured for all remote storage systems
for which the round trip time has not yet set, and these times are set to the
system as base information to optimize REC performance. This mode is
recommended for initial setup.
manual Manual mode. Round trip times are measured for the specified single remote
storage system. The displayed times can then be saved to the system if desired.
Optional. This parameter specifies the Box ID of a single remote storage system. Only one Box
ID can be specified at a time.
•
When "-mode auto" is specified, this parameter cannot be specified and when "-mode manual" is
specified, this parameter must be specified.
•
Box IDs use a maximum of 40 alphanumeric characters, spaces, and pound key characters (#).
•
All alphabetic characters are handled as uppercase.
•
The pound key characters (#) are automatically appended when the input characters are less than 40.
Optional. This parameter specifies the save mode. If omitted, the displayed round trip time can
be saved to the system if requested by the operator. If "-mode auto" is specified, this
parameter cannot be specified.
yes Path multiplicity is automatically set to the recommended multiplicity.
no Path multiplicity is not set.
