Is there any way to verify that pciid is locked and stay assured that everytime it would expect (/) at c1d0p1? Since it has changed in our case, it is important to check that. >> Does anyone know what can cause this device name to swap, & how does >> it effect server in case it happens again?

Yes, I believe so, looked at the grub.conf it no where mentions any name like c1d0 or c0d0. > > Easy way to test this is using usb keys. get 2 of them insert them in > some order, pvcreate, vgcreate, allocate to a lv. then shutdown and > remove the drives. bring the machine back up, reinsert in 'different > order', pvscan; check for results. Good suggestion, BTW is there any way we can control this naming, with program such as udev? I am bit concerned about, what happens if it flips and it expects root at c0d0p1, in that case what should i do?
