Configuring the SAN Extension Tuner
SCSI Tape Read/Write Assignment
You can assign SCSI tape read and write commands on a one-time basis or on a continuous basis.
Note
There is only one outstanding I/O at a time to the virtual N-port that emulates the tape behavior.
To assign SCSI tape read and or write commands on a one-time basis, follow these steps:
Step 5
switch(san-ext-nport)#
transfer-ready-size
512000
Specifies the maximum transfer ready size of
512,000 bytes as a target for SCSI write
commands. For a SCSI
write
command with
a larger size, the target performs multiple
transfers based on the specified transfer size.
switch(san-ext-nport)#
no
transfer-ready-size
512000
Removes the specified transfer ready size
configuration for SCSI write commands.
Step 6
switch(san-ext-nport)#
stop command-id 100
Stops the command with the specified ID.
Step 7
switch(san-ext-nport)#
end
switch#
Exits the SAN extension tuner submode.

san-ext-tuner
switch(san-ext)#
Enters the SET configuration submode.
Step 2
switch(san-ext)#
nWWN 10:00:00:00:00:00:00:00
Configures the nWWN for the SAN
extension tuner.
Step 3
switch(san-ext)#
nport pWWN
12:00:00:00:00:00:00:56 vsan 200 interface
gigabitethernet 3/4
switch(san-ext-nport)#
Creates a virtual N port on the specified
Gigabit Ethernet port and VSAN. This N port
can act as an initiator or a target.
Step 4
switch(san-ext-nport)#
tape-read command-id 100
target 22:22:22:22:22:22:22:22 transfer-size
512000 num-transactions 5000000
filemark-frequency 32
Specifies a transfer size of 512,000 bytes
with space over the filemark every 32 SCSI
read commands. The total number of I/Os is
5,000,000 bytes.
Step 5
switch(san-ext-nport)#
tape-write command-id 101
target 22:22:22:22:22:22:22:22 transfer-size
512000 num-transactions 5000000
filemark-frequency 32
Specifies a transfer size of 512,000 bytes
with filemarks written every 32 SCSI write
commands. The total number of I/Os is
5,000,000 bytes.
Step 6
switch(san-ext-nport)#
stop command-id 100
Stops the command with the specified ID.
switch(san-ext-nport)#
stop all
Stops all outstanding commands.
Step 7
switch(san-ext-nport)#
clear counters
Clears the counters associated with this N
port.
Step 8
switch(san-ext-nport)#
end
switch#
Exits the SAN extension tuner submode.
