My two cents:
What would be good to know is the best way to exploit the famed zSeries I/O
capabilities. I have questions like:
- How many PAV "paths" should I use for optimal I/O?
- What does the IOCDS configuration look like?
- What has to be done differently on the z/VM user ID?
- On Linux, does the logical volume still have to be striped?
- Can I have a non-striped logical volume with PAV and still get an I/O
performance boost?
- If so, can the logical volume be extended with vgextend?
- Can I have a 1TB logical volume with PAV?, 2TB?
Such a HOWTO would be a great resource for the zLinux community!
