Many thank's all with the answers received. We will continue to invest on high
availability on Parallel sysplex. Thank's

Yes Rob, we are base sysplex and GDPS was proposed to do things in seconds
without Parallel sysplex. that we understand is not possible. Thank's

Yes that's right, and this imply a specific design of data infratructure, aka
two copies of data, software replicated. Many thank's.

Many thank's Lizette for your reply. I'm happy to see that the Parallel Sysplex
is the solution we can continue to invest on.
When IBM announce a 'Star Trek' solution we investigate on it. Don't hold it
against me just to be curious what others do and what the future can Be.
Thank's again.
As you said Rob. Interesting, since the "GDPS solution" was suggested by an IBM
representative. :)

Thank's Jan for detailed reply. Yes for the impact of LPM. We use it for
planned outages, and work fine. I cannot do with my sysplex, because your reply
is applicable to a Parallel sysplex, which is a HIGH step forward. From all the
reply, i understand that Parallel Syplex is really the solution
Sorry. i do not know all the solutions, but know what the GDPS and Hyperswap
do. I'm confused to invest many hard work on Parallel Sysplex if one day, i can
do LPM on Z with one clic. I think all the mainframe community would
appreciate...

Sorry but GDPS do not do this in seconds. it automate start / stop with
approximatively 30 mn of interruption and do dasd swap in seconds (base swap of
dasd). So the minimum interrupt time is 30mn-1hour when LPM do this **in
seconds**.
Sysplex do the job, but only in full parallel sysplex, whi
Thank's for the reply. No GDPS do not cover this specific area; it automate the
IPL stop end start process, in approximatively 30 mn.
With LPM on I series, the mobility of partition is in seconds !!! We use it on
planned outages and it work very well.
Z/OS is not the future ?
I'm am confused about one thing.
IBM has created the Live Partition Mobility on system I, with the
virtualization layer.
Why this doesn't exit on Z machines, with an integrated flavor of Z/VM for
example ?
Does IBM has intent to have such feature one day ?
I think this is nearly a 'revolution
