000017775 - RSA Security Analytics core device cannot be pinged after swapping out disks to complete RMA

• RSA Security Analytics core device cannot be pinged after swapping out disks to complete RMA
• Connectivity issues occur after an RSA Security Analytics Appliance RMA.
• Appliance appears to be started normally, however, it cannot be pinged nor ping any other hosts that are even in the same subnet.
• The ifconfig command shows no interface.
• the dmesg command shows eth0, eth1, etc. instead of em1, em2, etc.

To resolve the issue, perform the following steps:

1. Leave the configuration files as ifcfg-emX.
2. Modify /etc/udev/rules.d/70-persistent-net.rules to add 'emX' to 'NAME=' for the corresponding MAC address.
3. Reboot

If the interface name remains the same, backup and delete /etc/udev/rules.d/70-persistent-net.rules and reboot the appliance so the file can be regenerated. 

Alternatively, follow the steps below to work around the issue temporarily as "emX" naming convention is the new standard for the current Series 4S appliances.

1. Rename 
   
   • '/etc/sysconfig/network-scripts/ifcfg-em1' to '/etc/sysconfig/network-scripts/eth0'  
   • '/etc/sysconfig/network-scripts/ifcfg-em2' to '/etc/sysconfig/network-scripts/eth1'
   • and so on for all interfaces.
2. Modify 'DEVICE=emX' to 'DEVICE=ethX' for every ifcfg-ethX file.
3. Restart the network service:
   

   
   # service network restart
