3 Device discovery
Devices must be discovered (added to the HPDM asset database) by HPDM before they can be managed. See the following sections for information on different methods of device discovery:
●
Automatic registration (normal thin clients)
●
Automatic registration (PCoIP zero clients)
●
Searching for devices
●
Manually registering a device
●
Manually registering multiple devices
Automatic registration (normal thin clients)
When the device is attached to your network, its HPDM Agent will try the following methods to automatically register it with the HPDM Server. The HPDM Agent works through these methods in this order and stops as soon as one is successful.
If the HPDM Agent loses contact with its current HPDM Gateway or the device is rebooted, the automatic registration process restarts and will be run at regular intervals until it is successful.
1.
The device will check its own local configuration settings for a preset primary or backup HPDM
Gateway to use. These settings can be configured using the following steps: a.
Switch to Administrator Mode (see your device operating system documentation for instructions).
b.
Open the HP Agent applet in the control panel.
c.
Enter the IP address of the HPDM Gateway in the Current Gateway field.
d.
Click OK.
If the primary HPDM Gateway is set, the HPDM Agent will try to contact it. If that fails and a backup HPDM Gateway is also set, it will then try to contact that. If that also fails, the HPDM
Agent will move on to the next method.
2.
The HPDM Agent will check the device's DHCP lease file to see if tag 202 is defined. Tag 202 is interpreted as a string representation of the HPDM Server’s IP address, followed by a space and then the HPDM Gateway IP address.
For example, if the following value is found associated with tag 202 in the device's DHCP lease file, then the HPDM Agent will attempt to connect to the HPDM Gateway 192.168.1.1:
192.168.1.5 192.168.1.1
3.
If a DNS server exists on the device’s local network, a request is sent to the device to perform a lookup for the DNS name hpdm-gateway to identify the HPDM Gateway IP address.
4.
The HPDM Agent will send a request to the broadcast address of its subnet. If an HPDM
Gateway is present on the subnet, it will reply to the broadcast and the HPDM Agent will connect to it.

Automatic registration (PCoIP zero clients)
Using a DNS service record
HP PCoIP zero clients must have either a static domain name or access to a DHCP server to get the domain name via DHCP option 15 or 12.
If the DHCP server only supports DHCP option 12, the hostname string must contain the domain name.
To create a DNS service record:
1.
Open the DNS console, and select the zone containing PCoIP zero clients.
2.
Right click to display the menu, and then select Other New Records to display the Resource
Record Type dialog.
3.
Select Service Location (SRV) and click the Create Record button to display the New Resource
Record dialog.
4.
Set the Service value to _pcoip-broker (recommended) or _pcoip-tool. Set the Protocol value to
_tcp, set the Host offering this service to the fully qualified domain name (FQDN) of the HPDM
Gateway, and then click OK. Click Done.
5.
Restart the PCoIP zero clients. They will report to HPDM automatically.
If you want to set one or more backup HPDM Gateways, add other (_pcoip-broker or _pcoip-tool) service records with different priority values. A lower value means more preferred. Each record points to one HPDM Gateway.
For more information about setting multiple DNS service records for one service, go to http://en.wikipedia.org/wiki/SRV_record .
To troubleshoot this method:
1.
Verify the network information, including the IPv4 address and domains, of the PCoIP zero clients.
2.
The PCoIP zero clients have an embedded diagnostic tool. Use it to ping the HPDM Gateway address in the DNS service record.
Using a DHCP vendor class option
To create a vendor class:
1.
Open the DHCP console, and then select the DHCP server that the PCoIP zero clients are in.
2.
Right-click to display the menu, and then select Define Vendor Classes to display the DHCP
Vendor Classes dialog.
3.
Click the Add button to display the New Class dialog.
4.
Set the Display Name to PCoIP Endpoint, set the value to PCoIP Endpoint, and then click OK.
To set a vendor class option:
1.
Right-click the DHCP server to display the menu, and then select Set Predefined Options to display the Predefined Options and Values dialog.
2.
Set the Option class to PCoIP Endpoint, and click Add to display the Option Type dialog.
Automatic registration (PCoIP zero clients) 19
3.
Enter MC Address in the Name field, set the Data type to String, set Code to 1, and then click
OK.
4.
Set the Value of the MC Address to the IP address of the HPDM Gateway, and then click OK.
To enable a vendor class option:
1.
Select the Scope Options of the Scope that the PCoIP zero clients are in.
2.
Right-click to display the menu, and then select Configure Options to display the Scope Options dialog.
3.
Select the Advanced tab.
4.
Set the vendor class to PCoIP Endpoint, enable the MC Address option, and then click OK.
5.
Restart the PCoIP zero clients. They will report to HPDM automatically.
To troubleshoot this method:
1.
Verify the network information, including the IPv4 address and domains, of the PCoIP zero clients.
2.
The PCoIP zero clients have an embedded diagnostic tool. Use it to ping the HPDM Gateway address in the MC Address.
Searching for devices
HPDM can search a range of IP addresses for HPDM Agents and HPDM Gateways. There are two methods: Walking With IP Range and Walking With IP List. Each of these methods begin in the same manner:
1.
In the HPDM Console, click the HPDM Gateway tab.
2.
Right-click the desired HPDM Gateway and select Discover Device in the menu.
3.
Select the device type (normal thin client or PCoIP zero client).
4.
Proceed to Using the Walking With IP Range method on page 20 or
Using the Walking With IP
List method on page 21 , depending on the method you wish to use.
Using the Walking With IP Range method
To search using the Walking With IP Range method:
1.
Select Walking With IP Range, and then click Next.
2.
You can specify the range of IP addresses to search by using either an IP scope or by manually specifying an IP range. An IP scope is a range of IP addresses that you have built and saved for future scans.
To search using an IP scope:
▲
Select the Use Preset IP Scope checkbox, select an IP Search Scope, and then click OK.
To search using a manually-specified IP range:
▲
Deselect the Use Preset IP Scope checkbox, enter a Starting IP Address and an Ending IP
Address, and then click OK.
You can check the progress of the discovery by displaying the HPDM Gateways tab and selecting the name of the HPDM Gateway. The discovery progress will be displayed in the tasks pane at the bottom of the HPDM Console window.
