Configuration of SIOSDataReplTest

This test auto-discovers the volumes on the source system. For each volume, the test reports the mirror state, and thus sheds light on broken synchronization attempts. Besides, this test also captures network reconnects, which can potentially cause delays in replication. The test additionally reports the length of the write queue, so that you can figure out if too many writes are pending. The count of dirty blocks in the intent log and its impact on resynchronization time is also revealed.

The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• Specify the IP address of the HOST textbox for which this test is to be configured.

• Specify the PORT at which HOST listens.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
