stormirror

Manages volume based replication functions.

Local replication functions are supported as full copy mirrors of a source volume (for ETERNUS DX/AF) or as snapshots (pointer based) local mirrors of a source volume (for ETERNUS DX/AF).

Remote replication functions are supported as full mirrors in synchronuous and ansynchronous mode (for ETERNUS DX/AF).

Please note for the management of replication functions:

• All logical volumes of a mirror pair have to have a storid assigned.

• When using a list of mirror pairs, the following applies:

  • All sources must be in the same storage system and all targets must be in the same storage system.

  • Only one mirror of a source can be managed in one call.

  • All mirror pairs must have the same mirrortype, replica, copymode and status.

Functions

The –function parameter supplies one of the following functions:

–create

creates new local or remote mirror pair(s) for logical volume(s) by establishing a mirroring relationship between source volume(s) and mirror volume(s)

–modify

Modifies the remote copy mode for remote mirror pair(s) from  synchronous to asynchronous and back

–restart

restarts local or remote mirroring function for mirror pair(s)

–restore

restores local mirror volume(s) of mirror pair(s) to source volume(s)

–suspend

suspends mirroring on local or remote mirror pair(s). Afterwards the  mirror volume(s) are available for direct access from server.

–swap

reverses the roles of local or remote mirror pair(s)

–terminate

terminates local or remote mirroring relationship for mirror pair(s)

–show

displays information related to local or remote mirror pair(s)

If the –show function is specified, the output format can be selected by specifying the -format parameter.
