In your code, you'd have to break out of the loop when the test passes. Or, do the test directly in while, then read at the end of loop:

Code:
#!/bin/bash

echo "Please enter the source system: "
read SYSTEM_NAME

while ! [[ $SYSTEM_NAME == "L1" || $SYSTEM_NAME == "L2" || $SYSTEM_NAME == "P1" || $SYSTEM_NAME == "P2" ]] ; do
      echo "\nPlease enter the source system as L1 L2 P1 P2"
      read SYSTEM_NAME
done

echo "Making $SYSTEM_NAME as source system for particular script"

#continue with  $SYSTEM_NAME

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
