Configuring Host iSCSI “no traffic” reattach
Follow these steps to automatically reattach dropped multipath connections that are currently
carrying no traffic.
1. Change the EnableNOPOut parameter for the iSCSI Initiator in the Windows registry (iSCSI
Ping):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E97B-E325-11CE-BFC1-08002BE10318}\0005\<parameters>]
NOTE: The \0005\ part of the registry path may be a different decimal number, such as
\0003\.
2. Change the <parameters> value from 00000000 to 00000001:
"EnableNOPOut"=dword:00000000
3. Reboot the server(s) for the change to take effect.
