Hi,
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?
I am running Solaris 10 U7.
Is this device attached to an mpt controller? If so,
then mpt's firmware (not the driver) will assign a
new target id to the device that you replaced, and
will keep doing so until you get to (iirc) 120.
So yes, what you saw is expected.
Assuming this is an mpt-attached device, then you won't
be able to use the same cXtYdZ name as the old device.
It really shouldn't be a problem for you.
