set rec-round-trip-time

The REC round trip time is set based on the result of the "measure rec-round-trip-time" command. However,
the REC round trip time for individual paths can be tuned in order to maximize REC performance. This
command is used to manually set the REC round trip time.
If the round trip time is specified, the path multiplicity is automatically changed to the recommended
multiplicity.
■ Syntax
set rec-round-trip-time -remote-boxid
■ Parameter
-remote-boxid
-time
■ Example(s)
The following example sets the multiplicity to 5.
CLI> set rec-round-trip-time -remote-boxid "00DXL#########ED06F21AUABCPJ000001######" -time 5
remote_storage_system_box_id
This parameter specifies the Box ID of a single remote storage system. This is the storage
system for which the REC round trip time is to be manually set.
• Box IDs use a maximum of 40 alphanumeric characters, spaces, and pound key characters
(#).
• All alphabetic characters are handled as uppercase.
• Hash marks (#) are automatically appended to Box IDs shorter than 40 characters in
length.
This parameter specifies the REC round trip time. The possible values are from 1 to 65535
milliseconds. The following ranges are recommended:
Asynchronous Through Mode: 100ms or less
Synchronous Transfer Mode: 50ms or less
