Re: I hosting I safeguard for PWRDWNSYS

Absotively!

I have written some Reasonably flexible CL that allows me to send SSH 
commands to HMC as well as Storwize, and Fiber switches too (add zones 
for example).  With this you can check things or you could move tape 
drives or create or start partitions or check who owns the tape drive. 
The possibilities are literally endless!

Done correctly the output (return from the command) ends up in a file 
member. You can then simply read that with your favorite language (Mine 
is CL) and react based on that.

I set my code up to allow for either a single return (e.g. who owns the 
tape drive) or a list of returns which I send back in a data queue. 
(e.g. list the WWNs for a partition so I can create the fiber zoning)

Other things I've set up are reaching out to Storwize to start a flash 
copy or to end a flash copy. Then reaching out to HMC to IPL the 
partition we just flashed into existence.

I could play with this stuff for days, if I had days.....
