HP StorageWorks B-Series Remote Replication Solution Best Practices Guide (5697-6731, June 2007)

-r retransmissions
Specifies the ma ximum retransmissions. Retransmissions
values are 1 to 8; default is 8. If tape pipelining is
enabled, the de
fault value is calculated based on the
minimum retra
nsmit time to ensure that tcp connection
does not timeo
ut before the host times out. If the user
changesthisv
alue, the value specified must be greater
than the calc
ulated value.
-s
Disables sel
ective acknowledgement c ode (SAC K) on
the tunnel specified.
-t
Enables tape pipelining on the tunnel specified (requires
fastwrite t
o be turned on). This argument cannot be used
together wi
th -ike, -ipsec or -key (IPSec).
NOTE:
Only a single IPSec-enabled tunnel can be
configured on a port. No other tunnels (IPSec
or otherwise) can be configured on the same
port. Jumbo frames will not b e supported
on secure
tunnels. Only a single route is
supporte
donaninterfacewithasecure
tunnel.
Arguments
modify tu
nnel_id
Modifies t
he properties of the existing FCIP tunnel. This
will disrupt the traffic on the FCIP tunnel specified for a
brief period of time. If the FCI P tunnel has IPSec enabled,
it cannot be modified. To change it, you must delete it
and recreate it.
Optional
Arguments
-b comm_rate
Specifies the desired com m itted rate for the existing
tunnel.
-c 0|1
Disable (0) or Enable (1) compression on the existing
tunnel.
-f 0|1
Disable (0) or Enable (1) fastwrite on the existing tunnel.
-k timeout
Specifies the keep alive timeout, in seconds, for the
existing tunnel. timeout values are 8 to 7,200; default is
10. If tape pipelining is enabled, the minimum value
is 80.
-m time
Specifies the minimum retransmit time, in milliseconds,
for the existing tunnel. time values are 20 to 5,000;
default is 100.
-r retransmissions
Specifies the maximum retransmission for the existing
tunnel. retransmission values are 1 to 16; default is 8. If
tape pipelining is enabled, the default value is calculated
based on the minimum retransmit time to ensure that tcp
connecti on does not timeout before the host times out. If
the user changes this value, the value specified must be
greater than the calculated value.
