Switch Diagnostics Dialog Box - HP StorageWorks 8/20q User Manual

• Offline—A disruptive test that exercises all port connections for a switch in the diagnostics state. When
you run an offline test, the switch will automatically be put into diagnostics state, and the switch will not
be returned to its original state until the Switch Diagnostics dialog box is closed. A disruptive switch
reset must be done at that time to return the switch to its original state.
• Connectivity—A disruptive test that exercises all port and inter-port connections for a switch in the
diagnostics state. When you run a connectivity test, the switch will automatically be put into diagnostics
state, and the switch will not be returned to its original state until the Switch Diagnostics dialog box is
closed. A disruptive switch reset must be done at that time to return the switch to its original state. The
two types of connectivity tests are internal loopback and external loopback.
