Creating Storagesets 3–53
n DESTROY (default) overwrites the user data and forced-error
metadata on a disk drive when it is initialized.
n NODESTROY preserves the user data and forced-error metadata
when a disk drive is initialized. Use NODESTROY to create a
single-disk unit from any disk drive that has been used as a member
of a mirrorset. See the REDUCED command in the Appendix B,
“CLI Commands,” for information on removing disk drives from a
mirrorset.
The NODESTROY switch is not valid for RAIDsets and single-
disk configurations.
See Appendix B, page B–73, for more information on the Destroy/
Nodestroy switch.
