--FOR /etc/sysconfig/network-scripts/ifcfg-<network device connecting to COMPELLENT> --Change the following...

  NETMASK=255.255.252.0

--FOR /var/lib/iscsi/iface/<network device connecting to COMPELLENT> --Change/Add the following...

  iface.ipaddress = <IP to COMPELLENT>       
  iface.hwaddress = <MAC Address of network device connecting to COMPELLENT>

 Run this :  ifconfig ens224 |egrep -w inet  |awk '{print " iface.ipaddress = "$2}';ifconfig ens224 |egrep -w ether | awk '{print " iface.hwaddress = "$2}' ### with the correct network device name

   --Example for /var/lib/iscsi/ifaces/p7p1

   iface.iscsi_ifacename = p7p1          
        iface.ipaddress = 10.1.2.134

--FIND the files in /var/lib/iscsi/nodeiqn.2002-03.com.compellent:5000d3100572ee*/10.1.2.22,3260,0/

cd /var/lib/iscsi
ls -1 ifaces |awk '{print "find . -name " $1 " -print"}' | sh  

If the files nodes/iqn.2002-03.com.compellent:5000d3100572ee*/10.1.2.22,3260,0/ are not using the correct iface ...

  cd /var/lib/iscsi/nodeiqn.2002-03.com.compellent:5000d3100572ee*/10.1.2.22,3260,0/ 
  mv <iface file name found> <network device connecting to COMPELLENT>

Some commands that might help doing this...

find . -name <iface name>  -print |awk '{print "mv " $1 " "$1}' 
find . -name <iface name> -print |awk '{print "mv " $1 " "$1}'  >/tmp/mvem
vi /tmp/mvem # change the second iface name to the new one to be used
sh /tmp/mvem
find . -name <iface name> -print |awk '{print "vi " $1}'  >/tmp/viem

Add the following lines to the complete set of files found in /var/lib/iscsi/nodeiqn.2002-03.com.compellent:5000d3100572ee*/10.1.2.22,3260,0/

   iface.hwaddress = <MAC Address of network device connecting to COMPELLENT>
   iface.ipaddress = <IP to COMPELLENT>       
   iface.iscsi_ifacename = <network device connecting to COMPELLENT>

   iface.hwaddress = 00:50:56:a2:77:ba
   iface.ipaddress = 10.1.2.134                
   iface.iscsi_ifacename = ens224

--FOR /etc/iscsi/iscsid.conf
--Change the following...(This might be correct.)
  node.session.iscsi.FastAbort = Yes  ### No to Yes

--CONFIRM ENTRIES in /etc/multipath.conf
   /sbin/multipath -ll
   /sbin/pvscan

At this point a reboot should be done to load the correct values changed above.

The alternative to this is to umount all the luns and delete all the files created by the discovery process and starting over... Those insructions can be found in Migrate-to-Compellent.html
Once that is done do the compelete process of created an iface file with the correct name of the network device, discovery and login session check and mounting of the luns..
