The SRP window opens.
Step 2 Click the Global tab.
Table 13-2 describes the fields in the tab.
Table 13-2 Global Attribute Field Descriptions
Field
|
Description
|
DefaultGatewayPortMaskPolicy
|
Boolean value that indicates if ports allow new SRP initiators to communicate through the Fibre Channel interface card(s).
|
DefaultLunPolicy
|
Boolean value that indicates if new SRP initiators have immediate access to target LUNs.
|
DefaultItlHiMark
|
Maximum number of requests that can be sent per logical unit. This value, an integer, falls between 1 and 256. This value defaults to 16.
|
DefaultItlMaxRetry
|
Number of times that an initiator may send the same I/O to a logical unit. Increase the value if you expect heavy traffic, or increase the default-itl-min-io-timeout value. The value, an integer, falls between 1 and 100. The value defaults to 5.
|
DefaultItlMinIoTimeout
|
Maximum amount of time for a logical unit to accept I/O traffic. Increase this value if you use a known slow connection, or increase the default-itl-max-retry value. The value, an integer, falls between 1 and 1800. The value defaults to 10 seconds.

•Click the nonRestricted radio button to grant new initiators access to Fibre Channel gateway ports.
Step 4 In the DefaultLunPolicy field, click one of these radio buttons to configure the LUN mask policy:
•Click the restricted radio button to deny new initiators access to logical units.
•Click the nonRestricted radio button to grant new initiators access to logical units.
Step 5 Configure global defaults for nonsequential (random) storage devices as follows:
a. In the DefaultItlHiMark field, enter an integer value, between 1 and 256, to specify the maximum number of requests that Fibre Channel gateways send to individual logical units.
b. In the DefaultItlMaxRetry field, enter an integer value, between 1 and 100, to specify the number of times that an initiator may send the same I/O to a logical unit.

b. In the DefaultSeqItlMaxRetry field, enter an integer value, between 1 and 100, to specify the number of times an initiator may send the same I/O to a logical unit.
c. In the DefaultSeqItlMinIoTimeout field, enter an integer value, between 1 and 1800, to specify the amount of time (in seconds) for an ITL to accept I/O traffic.
d. (Optional) Check the DefaultSeqItlDynamicPathAffinity check box.
