Shutdown(block='false') only works via Admin Server, not managed servers

Question

Hello,
We want to shut down all 10 managed servers in our domain gracefully, and in parallel. 5 of those managed servers are on the same OS/host as the AdminServer, the other 5 are on a separate OS/host (i.e. we have 5 x 2-node clusters).
I'm writing scripts to gracefully shut down all of our servers upon an OS reboot command. On the OS with the AdminServer (and 5 managed servers), I can simply do this:
connect(user, pwd, http://localhost:7001)
shutdown('myserver1', 'Server', block='false')
shutdown('myserver3', 'Server', block='false')
shutdown('myserver5', 'Server', block='false')
shutdown('myserver7', 'Server', block='false')
shutdown('myserver9', 'Server', block='false')
All 5 servers will be shutting down at the same time. If they each took 2 minutes to shut down, the whole shutdown process would take 2 minutes.
However, on the OS running the other managed servers, I cannot assume that the AdminServer [on the other OS] will be online. Hence, I would like to gracefully shut down each server locally like this:
connect(user, pwd, url='t3://localhost:8001')
shutdown(block='false')
disconnect()
connect(user, pwd, url='t3://localhost:9001')
shutdown(block='false')
disconnect()
connect(user, pwd, url='t3://localhost:10001')
shutdown(block='false')
disconnect()
connect(user, pwd, url='t3://localhost:11001')
shutdown(block='false')
disconnect()
connect(user, pwd, url='t3://localhost:12001')
shutdown(block='false')
disconnect()
NOTE that the ports are different (i.e. I connect via WLST to the managed servers themselves rather than to the AdminServer).
Unfortunately, in this scenario, the block='false' does not work. WLST waits until the managed server is shut down before proceeding to the next connect() command. So if each server took 2 minutes to shut down, the whole shutdown process now takes 10 minutes.
We don't want to use the nmKill() command on the local Node Manager because we want a graceful shutdown.
What options do we have to issue a graceful shutdown command either to a local Node Manager or to the managed servers themselves (since we can't expect the AdminServer to be online when our script runs)?
Best regards,
Michael

Hi Mike,
WLST will create it temp directory with /var/tmp/wlstTemp which is shared by all users. Since we cannot differentiated by different users which cause block on particular user at that time.
One solution is to grant write access to all users to the directory where the WLST temporary directory is created (e.g. on Solaris /var/tmp; you can verify the default on your system by executing java utils.getProperty and search for java.io.tmpdir).
If for whatever reason you cannot grant these access modes on the temporary directory, then you can create a directory somewhere on the file system where every user has the correct permissions.
Start the scripting tool with one the following options to redirect the cache files to the specified directory. Dependent on your environment one or the other will apply.
java -Djava.io.tmpdir=<path-to-tmpDir> weblogic.WLST
or
java -Dpython.cachedir=<path-to-tmpDir> weblogic.WLST
This will be useful to make shutdown of servers without any problem.
Note: block=false will always works it should not be the problem.
