Need to shorten disruptive time when reconfiguring nodes

System : IBM Storwize series
Actor : User needs to improve I/O wait time during Storwize microcode (SVC code) upgrading.

When concurrent SVC code upgrading on Storwize storage series, we need to "reconfigure" a node to the cluster after code update. Now it take closed 20 secs to 30 secs in this customer's environment and servers have to stop all I/O operation during that time. Yes, that may met the limitation of OS timeout, like as 30 secs in Windows, AIX and so on, but VMware ESX shows time-out errors when ESX detects no response from storage device over 14 secs. The customer as infrastructure service unit cannot accept the long waiting time over 14 secs. So disruptive time of Storwize SVC code upgrading should be shorter than 14 secs or less.
