First

1. destroy the d5 metadevice: metaclear -f /dev/md/dsk/d5 (won't work without the -f)
2. rebuild the d5 metadevice: metainit d5 -r c1t0d0s5 c1t1d0s5 c1t2d0s5 c1t3d0s5 c1t4d0s5 c1t5d0s5

1. newfs it:
2. mount it as /newscratch?
3. then how does it go?

Second

1. remove c1t4d0* from all its metadevices
   • d5

2. destroy d5
3. reformat the disk (with a new VTOC)
4. rebuild:
   • metadb
   • d31
   • d81
