7–72 CLI Commands
Specify NOPOLICY to prevent the controller from automatically replacing a failed
disk device. This causes the mirrorset to operate in a reduced state until either
POLICY=BEST_PERFORMANCE or POLICY=BEST_FIT is selected, or a
member is manually replaced in the mirrorset. See “SET mirrorset-name,”
page 7–110.
Example
This example shows how to create a one-member mirrorset from each member of a
stripeset. These commands set the nominal number of members in each mirrorset to
two and adds a second disk to each mirrorset. It is not necessary to initialize the
mirrorsets or add them as units; the higher-level structure of the stripeset is carried
down to the mirrorsets.
