My previous question regarding testing disk failures when using DiskSuite
lead me to another question. I reviewed a few scripts that are intended to
configure DiskSuite mirroring on a system. One of them used 'fmthard' to
rewrite the VTOC on a disk that was in use as the root disk. I think I
understand how 'fmthard' works to rewrite the VTOC. Based upon my
understanding, it would seem that using the 'fmthard -s new_vtoc
/dev/rdsk/c0t0d0s0' construct on a mounted disk, especially one that
contains the root filesystem, would be bad.
Am I correct in my understanding? Or is there something that I don't
understand about how this works?
