Re: [Engine-devel] Low Level design for HotPlug/HotUnplug feature
----- Original Message -----
Suppose, we unplug and then re-plug a disk, will VDSM expect the
disk
be
in the same device path as before? More generic, will the unplugging
and plugging keep the PCI device path as the same as before?
No guarantee for that.
For example, suppose you unplug a disk, plug another disk then re-plug the first one.
Unplug is just like removing a physical disk from your machine, the disk does not have any
property stating what PCI address it had.
It would be nice though if the address were kept and when plugging, if the address is not
taken then use the same one and if taken then remove address and let the system choose
where to place it...
