Run a Read/Write Buffer Test

hba wwpn = World wide port name of the adapter
-ex or -exclude = World wide port name of the target device that is
excluded from the read/write test
param name = One of the following:
DataPattern (see “DataPattern (DP)” on page 4-21)
DataSize (see “DataSize (DS)” on page 4-23)
TestCount (see “TestCount (TC)” on page 4-23)
TestIncrement (see “TestIncrement (TI)” on
page 4-23)
OnError (see “OnError (OE)” on page 4-24)
