Use this information to set up and configure devices, and to learn about your system's configuration.</p> <p>A device is a piece of equipment that is connected to your system. Most hardware, including internal processors, ports and adapters, drives, communications hardware, workstations, and printers are considered devices. To manage these devices, the operating system organizes these devices by their type, such as workstation or optical drive (CD-ROMs), and identifies specific devices by their resource name. For most internal devices, like processors, adapters and ports, the operating system automatically assigns the resource name. For most external devices, and some internal storage devices, the iSeries server manages communication with the device through a device controller. Most devices managed through a controller have resource names defined by their device description. You can use the device type to learn its resource name, physical location, current status, and other information.</p> <p>Every device in the system has a current status that describes whether it is turned on, and whether it is currently communicating with the system. Before a device can function, both this device and all devices connecting it to the iSeries server must be varied on (Operational) and functioning. For example, if a communication line or network adapter is varied off, any device attached to the iSeries server through those devices will not function.</p> <p>Most devices have the following possible types of status:</p> <div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="border" border="1" rules="all"><caption>Table 1. Possible types of status for most devices</caption><thead align="left"><tr valign="bottom"><th valign="bottom" width="12.5%" id="d0e41">Status</th> <th valign="bottom" width="87.5%" id="d0e43">Description</th> </tr> </thead> <tbody><tr><td valign="top" width="12.5%" headers="d0e41 ">Varied off</td> <td valign="top" width="87.5%" headers="d0e43 ">The operating system has disabled the device, and it must be varied on again before communicating with the iSeries server</td> </tr> <tr><td valign="top" width="12.5%" headers="d0e41 ">Varied on (Operational)</td> <td valign="top" width="87.5%" headers="d0e43 ">The operating system has enabled communications with the device, and is waiting for communications.</td> </tr> <tr><td valign="top" width="12.5%" headers="d0e41 ">Pending</td> <td valign="top" width="87.5%" headers="d0e43 ">The operating system is attempting to enable communications with the device.</td> </tr> <tr><td valign="top" width="12.5%" headers="d0e41 ">Active</td> <td valign="top" width="87.5%" headers="d0e43 ">The device is currently busy communicating with the server, and cannot be varied off.</td> </tr> </tbody> </table> </div> <p>Other types of status are possible for some specific device types, or to indicate a specific problem. For example, a workstation that is waiting for a user to sign on will have a status of Signon display, and a device that the operating system is unable to locate will have a status of Resource not detected.</p> <div class="section"><h4 class="sectiontitle">View and manage devices</h4><p>iSeries Navigator allows you to display the current status, physical location, and configuration information for devices. To work with devices in iSeries Navigator, expand <span class="uicontrol">Configuration and Service</span> and select <span class="uicontrol">Hardware</span>. You can display detailed information about the device, including its model, type and serial number, physical location in the iSeries server, and logical address by right-clicking on the device and selecting <span class="uicontrol">Properties</span>. Additionally, iSeries Navigator provides many functions for managing tape devices, disk units, and pools. See the online help in iSeries Navigator for more information.</p> <p>To change the status or properties of a device, you must use the character-based interface and type <kbd class="userinput">go device</kbd> from any command line.</p> </div> </div> <div> <div class="familylinks"> <div class="parentlink"><strong>Parent topic:</strong> <a href="rzal2manageops.htm" title="Use this topic to find procedures and supporting information for common system tasks.">iSeries basic operations</a></div> </div> <div class="relinfo"><strong>Related information</strong><br /> <div><a href="../books/sc415121.pdf" target="_blank">Local Device Configuration PDF</a></div> </div> </div> </body> </html>
