• 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 placed in the mirrorset (see SET
mirrorset-namepage 2–130).
Example
The following steps show how to create a striped mirrorset with full redundancy:
1. Create a normal stripeset.
2. Create a unit from the stripeset.
3. Make each member of the normal stripeset a mirrorset containing two members.
The commands used in the script below set the nominal number of members in each
mirrorset to two and add a second disk to each mirrorset. Because the higher-level
structure of the stripeset is carried down to the mirrorsets, initialization of the
mirrorsets or adding them as units is not necessary.
