Hi,
I have managed to get the disk names to change to c4t8d0-c4t13d0 by
turning the D2 off and on.
However, format command still shows the old disks names (t0-t5) as well
as the new names. The command shows the old disks c4t0d0-c4t5d0 are
'drive not available: formatting'.
Will a "devfsadm -C" get rid of the old disks names in shown in format
or is a reconfiguration reboot the preferred solution?
Thanks in advance.
