Configuring a Data Pattern

To optionally configure a data pattern for SCSI commands, follow these steps:
Command
Step 1
switch# san-ext-tuner
switch(san-ext)#
Step 2
switch(san-ext)# nport pWWN
12:00:00:00:00:00:00:56 vsan 200 interface
gigabitethernet 3/4
switch(san-ext-nport)#
Step 3
switch(san-ext-nport)# data-pattern-file
bootflash://DataPatternFile
switch(san-ext-nport)# no data-pattern-file
Step 4
switch(san-ext-nport)# write command-id 100
target 22:22:22:22:22:22:22:22 transfer-size
512000 outstanding-ios 2 num-transactions
5000000
Step 5
switch(san-ext-nport)# stop command-id 100

Chapter 42 Configuring the SAN Extension Tuner
Purpose
Enters the SET configuration submode.
Configures the nWWN for the SAN
extension tuner.
Creates a virtual N port on the specified
Gigabit Ethernet port and VSAN. This N port
can act as an initiator or a target.
Configures SCSI tape read commands to be
issued continuously.
Use the stop command-id command
Tip
to stop the outstanding configuration.
Configures SCSI tape write commands to be
issued continuously.
Stops the command with the specified ID.
Stops all outstanding commands.
Clears the counters associated with this N
port.
Exits the SAN extension tuner submode.
Purpose
Enters the SET configuration submode.
Creates a virtual N port on the specified Gigabit
Ethernet port and VSAN. This N port can act as
an initiator or a target.
Specifies the data pattern used by the N port to
generate data as a target for read commands
and initiator for write commands.
Removes the specified transfer ready size
configuration for SCSI write commands and
defaults to using the all-zero pattern.
Specifies a transfer size of 512,000 bytes with
two outstanding I/Os. The total number of I/Os
is 5,000,000 bytes.
Stops the command with the specified ID.
