Chapter 12 Command Line Interface Reference
scsirouter target profile
scsirouter target profile
To disable the use of an initial iSCSI Ready-to-Transfer (R2T) on connections coming to this target, use
the scsirouter target profile command.
scsirouter name target name profile {high | low}
Syntax Description
Defaults All targets are configured as high profile targets.
Command Modes Administrator.
Command History
Usage Guidelines The SN 5428-2 Storage Router supports up to 16 concurrent connections that do not use an initial R2T.
If there are 16 existing connections to targets configured as high profile, the 17th connection will be
handled as though the target were defined as low profile, causing the connection performance to be a bit
slower.
By default, all targets are defined as high profile targets to provide the best performance. Use the
scsirouter target profile command to configure targets that do not require the additional performance
as low profile targets.
Examples The following example configures the target labserver8 for SCSI routing instance lab4 as a low profile
target. Any host opening a connection to the labserver8 target cannot send any data to the target until
the target sends the host an R2T.
[SN5428-2A]# scsirouter lab4 target labserver8 profile low
name Name of the SCSI routing instance to which you are adding the target
profile.
target name The name of the storage target.
high Disable the use of R2T for the specified target. This allows a host that opens
a connection to the specified target to start sending data of a certain length
as if it had received an initial R2T.
low Enable the use of R2T for the specified target. This prevents a host that
opens a connection to the specified target from sending any data packets to
the target until the target has sent the host an R2T message. This adds
latency to data transfer activities to this target.
