Path Time Out
You can enable or edit the Path Time Out field only when MPIO is disabled.
Specifying Path Time Out using the GUI
1. Select Configure > Basic Port Configuration from the Host Connectivity Manager.
The Basic Port Configuration dialog box displays.
2. Type a value in the Path Time Out text field. Its value range is 0 to 60. A timeout value of 30 is
the default.
3. Click OK to close the window.
Specifying Path Time Out using the BCU
Enter the following command to set the MPIO mode to on or off. If the MPIO mode is off, you can
specify an optional path time out value (TOV) in seconds (1 to 60). A timeout value of 30 is the
default.
bcu fcpim - -pathtov < port_id > tov
Refer to “fcpim” on page 177 for details about this command.
Target rate limiting (HBA only)
NOTE
The target rate limiting feature is not supported on the converged network adapter (CNA).
The target rate limiting feature is used to minimize congestion at the adapter port caused by a slow
drain device operating in the fabric at a slower speed. A remote port’s operating speed is
determined from the fabric. Traffic destined to the remote port is limited to its current operating
speed.
Enabling and disabling rate limiting on the adapter side using the GUI
Target rate limiting is supported only when the adapter port is connected to the fabric. Therefore,
target rate limiting is not supported when the port is directly connected with another device.
1. Select Configure > Basic Port Configuration from the Host Connectivity Manager.
The Basic Port Configuration dialog box displays.
2. Enable the Target Rate Limiting feature by clicking the corresponding check box.
3. Select the default rate limit from the list. Options include 1 Gbps, 2 Gbps, and 4 Gbps; the
default is 2 Gbps.
4. Click OK to close the window.
