Introduction TABLE 1 Common troubleshooting problems and tools (continued) Problem area Investigate Hosts ∙ Physical issues between switch and devices ∙ Lower or incompatible HBA firmware ∙ Incorrect device driver installation ∙ Incorrect device driver configuration Storage Management Applications ∙ Incorrect installation and configuration of the storage devices that the software references. For example, if using a volume-management application, check for: ∙ Incorrect volume installation ∙ Incorrect volume configuration Tools ∙ Device LEDs ∙ Host operating system diagnostic tools ∙ Device driver diagnostic tools ∙ Switch commands (for example, switchShow or nsAllShow ) for diagnostics Also, make sure you use the latest HBA firmware recommended by the switch supplier or on the HBA supplier's website ∙ Application-specific tools and resources Questions for common symptoms You first must determine what the problem is. Some symptoms are obvious, such as the switch rebooted without any user intervention, or more obscure, such as your storage is having intermittent connectivity to a particular host. Whatever the symptom is, you must gather information from the devices that are directly involved in the symptom. The following table lists common symptoms and possible areas to check. You may notice that an intermittent connectivity problem has lots of variables to look into, such as the type of connection between the two devices, how the connection is behaving, and the port type involved.

Questions for common symptoms
You first must determine what the problem is. Some symptoms are obvious, such as the switch rebooted without any user intervention,
or more obscure, such as your storage is having intermittent connectivity to a particular host. Whatever the symptom is, you must gather
information from the devices that are directly involved in the symptom.
The following table lists common symptoms and possible areas to check. You may notice that an intermittent connectivity problem has
lots of variables to look into, such as the type of connection between the two devices, how the connection is behaving, and the port type
involved.
