Restart iscsi software service in esxi

To restart the software iSCSI stack ,we have to follow below steps

1. Disable the software iSCSI :
   esxcfg-swiscsi -d
2. Terminate the software iSCSI processes with the command:
   esxcfg-swiscsi -k
   
   In some cases, the iSCSI stack is in an unresponsive state and does not terminate on this command. If this happens, you must find the process ID and issue a terminate command directly to the operating system for this process.
   1. Obtain the process ID for the vmkiscsi processes with the command:ps ax | grep vmkiscsid
   2. Terminate the process with the command:
      kill <process ID>
3. Enable the software iSCSI configuration with the command:
   esxcfg-swiscsi -e
4. Perform a rescan of the software initiator with the command:
   esxcfg-rescan vmhba40
