hi ,
you can from HMC run commands that can give you information about different partitions , maybe change different partition settings , you'll have to probably write a script
to run certain commands on different partitions
see
what command are you trying to run ?

Thanks for the reply. What if I need to create a file system on all partitions at a time ? Is there anyway do get this done? We use dsh from SP Control work station to run scripts or commands on all the nodes attached to that CWS. I was wondering is there anything similar to dsh in partitioning environment?
You could do it with some good scripting and ssh.
1. write your script
2. deliver the script to the client with ssh private/public key pair
3. execute the script using ssh
I do things like this all the time. You may have to get tricky and use sudo if you have strict rules about remote logins as root.

What hfaix said is absolutely right
having him mentioning ssh i will say you can use rsh as well but ssh is more secure off course.
you just have to specify the hostname of the machine you want to use (machine1) to connect to the current machine(machine2). You just have to put machine1 name in .rhost file one machine2 on root directory (/).
then from machine1 you can use the following command:
rsh machine2 Action_to_be_done_on_machine2
example:
rsh machine2 ls -al
Exactly this can be used as specified by hafix with ssh (after configuring it)
ssh machine2 ls -al

You can install the csm.core and csm.client filesets without installing a 1600 cluster. The dsh command is in /opt/csm/bin and you can run it as you would for pssp.
# /opt/csm/bin/dsh -w node1 df
or set the working collection:
echo node1 > /tmp/nodelist
echo node2 >> /tmp/nodelist
# export WCOLL=/tmp/nodelist
# dsh df
# /opt/csm/bin/dsh -w node1 df
or set the working collection:
echo node1 > /tmp/nodelist
echo node2 >> /tmp/nodelist
# export WCOLL=/tmp/nodelist
# dsh df
