Re[2]: With SAN should you still use internal disk for vios?

I remember why that "Give me back my disk" capability exists, at least
the original version of it. Way back in the System/38 days we had
systems with 3370 drives attached in the System Test lab in Rochester.
Those were the perfect height for someone to set down a notebook or
briefcase and shut off the drive accidentally, which crashed the system
in the middle of our tests. Once it had happened enough times and the
microcode development team had to do diagnostics, we suddenly got an
update to the system that halted and waited for the 3370 to be turned
back on. I think that's what evolved into the way things work today for
loss of contact with a disk.

That was also about the time that Frank Soltis joked he was going to
lock me out of the test lab because I kept "breaking" the microcode. :-)

That time in System Test was some of the most fun I've had in my career!

Jim--

If I follow the user's success, they did NOT power down the Power hardware, but let it idle until the SAN was back up and running, then the IBM i partitions picked up where they left off.

That's what I like about IBM i. If it loses contact with its 'disks,' it posts a message that says "Give be back my disk."
