Getting started with Flash Accel : Discovering hosts and virtual machines

Discovering hosts and virtual machines
Discovering a resource gives Flash Accel access to it. You need to discover datacenter resources before you can configure them for caching.
Before you begin 
Make sure you have entered the default credentials for hosts and VMs. If the default credentials are not accepted on a host or virtual machine, you will need to manually enter the credentials before Flash Accel can be used to manage the resource.
Note: Hosts must have DNS mappings. Flash Accel cannot discover hosts that do not have DNS mappings. VMs must be pingable by Flash Accel. For best discovery results, VMs should have DNS mappings.
You can use the Flash Accel command line interface, called the Advanced Management Terminal (AMT), to ping hosts or VMs from the FAMC virtual machine. For more information, see "Pinging a resource from the FAMC virtual machine."
About this task 
Discovery can be time-consuming. You may want to discover a single datacenter first, so that you can get some idea of how much time it will take to discover an entire vCenter.
Steps 
1.
From the Navigation area of the FAMC, click Console Settings > Discovery.
Note: Ignore the Auto-Rediscover Settings section of the tab for this task.
2.
In the vCenter Inventory Details section, select the check box for each datacenter you want to discover. Click Select All to select all the datacenters, click Unselect All to unselect all the datacenters.
Note: Attempting to discover more than 5,000 VMs with a single FAMC instance may result in a failure of the discovery operation. The workaround is to use multiple FAMC instances, one instance per datacenter. If all 5,000+ VMs are in the same datacenter, no workaround is possible. For best discovery performance, manage no more than 2,000 VMs with a single FAMC instance.
If the check box for a datacenter is disabled, the datacenter is being managed by an instance of the Flash Accel Management Console running on another VM. If you are sure you want to manage the datacenter with your instance of the console (for example, because you know that the VM for the other instance has been deleted), click Enable Takeover. Click Disable Takeover if you do not want your instance of the FAMC to manage the datacenter.
Note: Do not attempt to manage a datacenter with more than one instance of the FAMC. Use only a single FAMC instance (accessible to multiple team members) to manage a datacenter.
3.
Click Discover All.
Click Discover New.
Note: When you perform a Discover All of a previously discovered datacenter, Flash Accel refreshes already discovered resources and discovers previously undiscovered resources.
A discovery confirmation dialog opens.
4.
A progress bar indicates the percentage of discovery complete. The duration of the process depends on the size of the selected datacenters. Wait until all resources have been discovered before attempting to configure hosts and VMs.
Result 
When discovery is complete, the FAMC host and VM inventories are updated with the discovered resources.
Use the Flash Accel command line interface, called the Advanced Management Terminal (AMT), to troubleshoot discovery issues. For more information, see "Pinging a resource from the FAMC virtual machine."
Note: You can use the FAMC export/import feature to import configuration information for hosts and VMs from a previous FAMC version. Initially, discovery of hosts and VMs using the imported credentials will appear to have failed. Their status indicators will be red, and you will see messages stating that the imported credentials are incorrect. Ignore these messages. Assuming no other problems were encountered, the hosts and VMs will be displayed correctly as soon as they are refreshed. For information on how to refresh hosts and VMs, see "Refreshing resources."
