+Predict network adapter name before deployment
+==============================================
+
+
+
+Traditionally, network interfaces in Linux are enumerated as eth[0123…], but these names do not necessarily correspond to actual labels on the chassis. customer need a methods to get consistent and predictable network device name before provision or network configuration. xCAT provide a tool ``getadapters`` to help customer to resolve this problem.
+
+
+**[Note]** : This feature needs to restart your target sever which you want to obtain network adapter from.
+
+How to use get adapters
+-----------------------
+
+
+Using below command to obtain the network adapters information ::
+ 
+    getadapters <noderange>
+
+Then will get output like below ::
+
+
+    The whole scan result:

+
+Every node gets a separate section to display its all network adapters information, every network adapter owns single line which start as node name and followed by index and other information.
+
+xCAT try its best to collect more information for each network adapter, but can’t guarantee collect same much information for every one. If a network adapter can be derived by xcat genesis, this adapter will have a predictable name, if it can’t be, it only has the information xcat can obtain.
+    
+below are the possible information:
+
+* **hitname**: the consistent name which can be used in ``confignic`` derectly in operating system which follow the same naming scheme with rhels7. (``confignic`` doesn’t need to do more work)
+
+* **pci**: the pci location
+
+* **mac**: the MAC address
+
+* **candidatename**: All the names which satisfy predictable network device naming scheme, if customer needs to customize their network adapter name, they can choose one of them. (``confignic`` needs to do more work to support this. if customer want to use their own name, xcat should offer a interface to get customer’s input and change this column) 
+
+* **vendor**:  the vender of network device
+
+* **modle**:  the modle of network device
+

+=head1 NAME
+
+B<getadapters> - Obtain all network adapters's predictable name and some other information before provision or network configuration.
+
+=head1 SYNOPSIS
+
+B<getadapters> I<noderange> [B<-f>]
+
+B<getadapters> [B<-h>|B<--help>|B<-v>|B<--version>|B<-V>]
+
+=head1 DESCRIPTION
+
+Traditionally, network interfaces in Linux are enumerated as eth[0123…], but these names do not necessarily correspond to actual labels on the chassis. B<getadapters> help customer to get predictable network device name and some other network adapter information before provision or network configuration.
+
+B<getadapters> use genesis to collect network adapters information, so that mean it need to restart the target node.
+
+B<getadapters> follows below scheme:
+
+If the target node is scaned for the first time, B<getadapters> will trigger genesis to collect information then save the information at local. 
+If the target node has ever been scaned, i.e. this node has network device information in local, B<getadapters> use the local information first.
+If user doesn't want to use local information, can use B<-f> option to force to trigger new round scan process.
+if part nodes of I<noderange> don't have network device information in local and the rest have, B<getadapters> only trigger real scan process for these nodes which don't have local information, the nodes have network device information in local, B<getadapters> still use the local information first.
+
+B<getadapters> tries to collect more information for the  target network device,  but doesn't guarantee collect same much information for every network device.
+
+Below are the possible information can be collect up to now:
+B<hitname>: the consistent name which can be used by confignic directly in operating system which follow the same naming scheme with rhels7
+B<pci>: the pci location
+B<mac>: the MAC address
+B<candidatename>: All the names which satisfy predictable network device naming scheme. I<(if xcat enhance confignic command later, user can use these names to configure their network adapter, even customize their name)>
+B<vender>:  the vender of network device
+B<model>:  the model of network device
+
+=head1 OPTIONS
+
+B<-h>          
+
+Display usage message.
+
+B<-v>          
+
+Command Version.
+
+B<-V>          
+
+Display verbose message.
+
+B<-f>
+
+Force to trigger new round scan. ignore the data collected before.
+
+
+=head1 EXAMPLES
+
+1. To collect node[1-3]'s network device information, enter:
+ 
+ getadapters  node[1-2]
+
+Output is similar to:
+
+-->Starting scan for: node1,node2
+The whole scan result:
+--------------------------------------
+[node1] with no need for scan due to old data exist, using the old data:
+node1:1:mac=98be9459ea24|pci=/0003:03:00.0|candidatename=enx98be9459ea24|vender=Broadcom Corporation 
+node1:2:mac=98be9459ea25|pci=/0003:03:00.1|candidatename=enx98be9459ea25|vender=Broadcom Corporation
+--------------------------------------
+[node2] scan successfully, below are the latest data
+node2:1:mac=98be9459ea34|pci=/0003:03:00.0|candidatename=enx98be9459ea34|vender=Broadcom Corporation 
+node2:2:mac=98be9459ea35|pci=/0003:03:00.1|candidatename=enx98be9459ea35|vender=Broadcom Corporation
+
+Every node gets a separate section to display its all network adapters information, every network adapter owns single line which start as node name and followed by index and other information.
+
+
+2. Force to trigger new round scan
+
+  getadatpers node -f
