Re: Connections.  are you referring to the iSCSI sessions to the array?   If so, those are dynamic.  When you shutdown they will go away.  If everything is the same, then technically yes.  You can shutdown reload and bring it back up. 
Hi,  We use EqualLogic, Windows 2008R2, HIT and iSCSI initiator to access volumes. Now I am re-installing OS to Windows 2012. All hardware, IP addresses, volumes, host name will be the same on new OS. Changes just OS. Will it be the correct way to remap iSCSI volumes back to new OS: 1. On windows 2008 R2 take volume offline in Disk Manager console.2. Disconnect "Discovered targets" in Windows iSCSI Initiator.3. Take volumes offline in Dell EqualLogic Group Manager (to reset connections).4. On new Windows 2012 install HIT 4.5 and configure (is this correct software version  for Windows 2012?)5. Enable volumes in Dell EqualLogic Group Manager.6. Discovery target and connect to targets.7. Take volumes online in OS Disk Manager console. Are these steps correct? Are all of them required? Is HIT 4.5 correct software for windows 2012? thanks    
Reattach EqualLogic iSCSI volumes to Windows 2012
