Re: Remove the Mirrored Root Disk
Remove mirror copies of logical extents of a logical volume from the
physical volume /dev/dsk/c1t0d0:
eg:lvreduce -m 0 /dev/vg01/lvol4 /dev/dsk/c1t0d0
lvreduce -m 0 /dev/vg00/lvname
Remove physical volume /dev/dsk/c0t1d0 from volume group /dev/vg01:
eg:vgreduce /dev/vg00 /dev/dsk/c0t1d0

Re: Remove the Mirrored Root Disk
No... I need to use this disk for an another VG. But I want to remove those partions. But it is done with #idisk -R.
Now I want to remove those device files. Should I need to run rmsf for all individual special files (for both block/character) or any other way?
