normal member A mirrorset member that, block-for-block, contains the same data as other normal
members within the mirrorset. Read requests from the host are always satisfied
by normal members.
normalizing Normalizing is a state in which, block-for-block, data written by the host to a
mirrorset member is consistent with the data on other normal and normalizing
members. The normalizing state exists only after a mirrorset is initialized.
Therefore, no customer data is on the mirrorset.
normalizing member A mirrorset member whose contents is the same as all other normal and
normalizing members for data that has been written since the mirrorset was
created or lost cache data was cleared. A normalizing member is created by a
normal member when either all of the normal members fail or all of the normal
members are removed from the mirrorset.
