I replaced one faulty disk with a new disk in the same disk slot. The
faulty disk has a device name as c2t6d0. I expect the system would use
the same device name for the new disk. However, it did not. Instead,
the system uses c2t14d0, which is next free available device name, for
the new disk. Is this epxected?
If I want to use the same device name, should I first unconfigure the
device and then reconfigure it after replacing faulty disk? Is
assigning device controllable?
Normally, you wouldn't try to reuse the old device name. Normally, you'd
just embrace the new name for the new device, and move on.
That would work until the next time the device tree is rebuilt. You
just have to follow the procedure shown in the docs or probably on line
in Google to "detach, offline, cfgadm" to remove the bad disk from ZFS
and from the device tree. You then use the above in the reverse order
to put the new disk back with the same device name.
