Managing Flash Accel caching systems : Refreshing resources : Refreshing resources automatically

Refreshing resources automatically
It is almost always a good idea to schedule a daily autorefresh in the Console Settings > Discovery tab. Autorefresh works like Discover All: Flash Accel refreshes already discovered resources and discovers previously undiscovered resources. The discovery preferences you set in this tab determine the datacenters Flash Accel discovers.
Before you begin 
Hosts must have DNS mappings. Flash Accel cannot discover hosts that do not have DNS mappings. For best discovery results, VMs should have DNS mappings as well.
About this task 
Depending on the size of the vCenter, the refresh can be time-consuming. Try to schedule the refresh during off-hours, when running it will not prevent you from working in the FAMC.
Steps 
1.
From the Navigation area of the FAMC, click Console Settings > Discovery.
2.
In the Hour to execute drop-down, select the hour (in 24-hour format) you want Flash Accel to refresh resources. The time is for the ESXi server hosting the FAMC. You can view the time on the server in the lower right corner of the FAMC.
3.
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.
4.
Click Discover All.
Click Discover New.
5.
Click Save Configuration.
Result 
Flash Accel refreshes the selected resources at the specified time.
Note: If you cancel the discovery operation, make sure to perform it again before attempting to use the FAMC.
After you finish 
Wait until all resources have been updated before attempting to configure hosts and VMs. If a host or virtual machine does not have a DNS mapping, you receive an error message for the device. You need to configure a DNS mapping for that device before Flash Accel can be used to manage the resource.
