Devices can be in a communication error status for several reasons, such as the device is turned off or the IP address assigned to the device has changed. If devices are in a communication error status because the IP addresses assigned to the devices have changed, you can use the Resolve IP Addresses wizard to rediscover these devices and resolve the status.
The Resolve IP Addresses wizard retrieves a list of all the devices that are currently in a communication error status, regardless of the reason for the communication error. For each of these devices, the wizard retrieves
ENWW Device Lists 111
the hostname assigned to the device, and then looks up the hostname in the Domain Name System (DNS) to determine if the corresponding IP address has changed. If a new IP address has been assigned to the device, the wizard adds that device to a list of devices to be rediscovered. The wizard then runs a Specified Addresses discovery using this list of devices to be rediscovered. If there are PC-connected devices and
network-connected devices in a communication error status, the wizard runs a separate discovery for each group of devices.
If you know that the IP addresses assigned to some of the devices on the network have changed, you can run the Resolve IP Addresses wizard one time to resolve the status of those devices. If the IP addresses assigned to the devices on the network change frequently, you can create a schedule to run the wizard on a recurring basis, such as daily, weekly, or monthly.
To resolve devices that are in a communication error status, perform the following steps:
1. Go to Tools > Resolve Device Communication Failures. The Resolve IP Addresses wizard starts.
2. To run the discovery immediately, leave the Schedule checkbox cleared.
-or-To create a schedule for the discovery, select the Schedule checkbox.
All schedules use the date and time on the server where HP Web Jetadmin is installed. The client used to access HP Web Jetadmin might not be in the same time zone as the server where HP Web Jetadmin is installed. You should be aware of the potential for time and date differences when configuring schedules.
3. Click the Next button. The Specify credentials page appears.
4. If credentials are required to discover the devices, select the Specify credentials to use for this discovery option, and then perform the following steps:
a. If the devices on the network have an SNMPv1 Get Community Name other than public defined, select the SNMPv1 Get Community Name checkbox, and then enter the SNMPv1 Get Community Name in the box.
b. If HP Web Jetadmin is configured to discover SNMPv3 devices, select the SNMPv3 Credentials checkbox, and then enter the user name, authentication password, and private password in the boxes.
NOTE: To enable HP Web Jetadmin to discover SNMPv3 devices, go to Tools > Options > Device Management > Device Discovery > General.
c. If the devices are connected to the network through a PC, select the WMI Credentials checkbox, and then enter the administrator (local) credentials for the Windows host that HP Web Jetadmin queries during the discovery in the boxes.
d. To use the global credentials, select the Use global credentials checkbox.
NOTE: To define the global credentials, go to Tools > Options > Shared > Credentials, and then select the appropriate option.
5. Click the Next button.
6. If you did not select the Schedule checkbox, the Confirm page appears. Perform the following steps:

a. Click the Start Resolving Devices button.
b. The Results page appears and shows the progress of the discovery. While the discovery is running, you can hide the Resolve IP Addresses wizard or cancel the discovery.
This discovery is available in the Devices – Scheduled Tasks task module on the Device Management > Overview page. You can view the progress or stop the discovery from this task module.
c. When the discovery is finished, the Results page indicates the status of the discovery and displays the number of devices that were found in a communication error status, the number of devices that were resolved, and the number of devices that were not resolved.
NOTE: If a device is in a communication error status, but the IP address assigned to the device has not changed or the Resolve IP Addresses wizard was unable to discover the new IP address found in the DNS, the wizard cannot resolve the status. The device remains in a communication error status.
d. Click the Done button.
7. If you selected the Schedule checkbox, the Specify schedule options page appears. Perform the following steps:
a. In the Name box, enter a name for this discovery schedule.
b. In the Start time boxes, specify the date and time this discovery starts.
c. In the Recurrence section, select the option that defines how often this discovery runs, and then specify the corresponding settings.
d. Click the Next button.
e. On the Confirm page, click the Create Schedule button.
f. The Results page appears and displays the details about the discovery. Click the Done button.
This discovery schedule is available in the Devices – Scheduled Tasks task module on the Device Management > Overview page. You can edit and delete the schedule from this task module.
