mirror
The mirror rule is used to describe one or more mirrors of a volume. All the basic rules except
striped and parity, and a restricted form of the stripe rule, can be used within a mirror
rule. Rules that are specified within a mirror rule apply only to those mirrors that are constructed
from this rule.
The following examples demonstrate the application of the mirror rule:
◆ Confine each mirror within an enclosure so that no mirror spans more than one enclosure:
mirror all {
confineto "Enclosure"
}
◆ Configure two mirrors of a volume with the EMCSnapshot feature:
mirror 2 {
apply EMCSnapshot
}
◆ Use confineto rules to force one mirror to be created on each of four separate enclosures:
mirror 1 {
confineto "Enclosure"="enclr1"
}
mirror 1 {
confineto "Enclosure"="enclr2"
}
mirror 1 {
confineto "Enclosure"="enclr3"
}
mirror 1 {
confineto "Enclosure"="enclr4"
}
