In this example, swap is made of a two-way mirror named d1; its submirrors are d11 and d21, which are made of slices /dev/dsk/c0t3d0s1 and /dev/dsk/c1t3d0s1, respectively. The metastat command verifies that at least one submirror is in the "Okay" state. (A mirror with no submirrors in the "Okay" state must first be repaired.) Submirror d21 is detached to make d1 a one-way mirror. Next, the /etc/vfstab file must be edited to change the entry for swap to reference the slice that is in submirror d21. For example, if d1 was the mirror, and d21 the submirror containing slice /dev/dsk/c0t3d0s1, the following line:
/dev/md/dsk/d1 - - swap - no - |
should be changed to:
/dev/dsk/c0t3d0s1 - - swap - no - |
After a reboot, the metaclear -r command deletes the mirror and the other submirror, d11. The final metaclear command clears submirrror d21.
