[HPADM] Multiple paths to a SAN disk

Next question for today...



I might not explain this clearly enough...



Our HP-UX servers have 2 fiber connections acting as redundant paths to
our SAN. Basically, we use pvlinks for path failover. The system has
just been provided a new disk. Ioscan is listing the device twice
basically with a different c/t/d.



I can't find anything on how to configure this dual-path device to put
it into LV management. I run pvcreate against both, for example, then
move on? Pvlinks only comes into play after I have a VG?



Ultimately, I need to use this new disk to increase an existing LVOL.
In the lab, my plan is to use a existing disk to create a VG/LVOL, then
use this new disk to extend it.



(Our docs have gone missing, and our memory is starting to fail.)



I can't remember if pvlinks applies to disks or VGs. Likely the latter,
but I'm going to look that up after lunch.
