Mirrorclone states

The following mirrorclone states are reported by the replication manager.

Mirrorclone state

Remarks

Fractured

There is no replication activity between the mirrorclone virtual disk and its

 

source virtual disk. At the instant of the fracture, data on the mirrorclone

 

is identical to its source. After a fracture, data on the two disks might no

 

longer be identical due to host I/O to the source or the mirrorclone.

Restore in progress

In response to a replication command, data is being copied from the

 

mirrorclone virtual disk to its original source virtual disk. Data on the

 

original source is not yet identical to its mirrorclone.

Synchronized or normalized

The source virtual disk and its mirrorclone are synchronized. Data on the

 

mirrorclone is identical to its source. Any changes to data on the source

 

virtual disk are automatically copied to its mirrorclone.

Sync in progress

In response to a user Sync command, data is being copied from the source

 

virtual disk to its mirrorclone virtual disk. Data on the mirrorclone is not

 

yet identical to its source.

Detached

When a mirrorclone has been detached, it is no longer a mirrorclone. It

 

becomes a normal virtual disk, independent of its source virtual disk.

Containers

A container is disk space that is preallocated for later use as a snapclone, a snapshot, or a mirrorclone. Snapshots and snapclones that are created using containers are called preallocated snapshots and preallocated snapclones, respectively. Use containers when you need faster copies, for example, to reduce the time a host application is suspended for a backup.

Follow these guidelines for using containers:

•The array must have a local replication license.

•When used for mirrorclones and preallocated snapclones, the container can be in a different disk group than the source virtual disk. When used for preallocated snapshots, the container must be in the same disk group as the source virtual disk.

•A container must be exactly the same size as the source of the preallocated snapclone or snapshot.

•The redundancy (Vraid) level of the container determines the redundancy (Vraid) level of a preallocated snapclone.

•For a preallocated snapshot, the redundancy (Vraid) level of the container must be the same or lower than the source. If the source has other snapshots, the redundancy (Vraid) level of the container must be the same as the other snapshots. For descriptions of redundancy (Vraid) levels, see “Redundancy (Vraid) levels” (page 29).

•Containers cannot be presented to hosts or used for storage.

•Virtual disks can be converted to containers, but only if they are not presented.

Containers cannot be created from a virtual disk that:

•Is a snapshot

•Has a snapshot or mirrorclone

•Is a member of a DR group

•Is presented to a host

•Is in the process of normalizing (snapclone in progress) or being deleted
