Configuring remote physical volume servers and clients

The RPV device driver is the software layer after LVM that is used by LVM to maintain geographically remote copies of the data. Similar to standard, or local physical volumes (PVs), remote physical volumes (RPVs) can become part of a volume group, a logical volume, and a mirror copy of a logical volume. RPVs differ from local physical volumes in that they have a site name associated with them. This is the site that hosts the RPV server.

Using SMIT you can:

• Configure RPV server and client pairs for volume groups
• Display the remote physical volumes (RPVs) that are configured in the cluster, and
• List the details of the RPVs that are used.
• You can also change the state of the RPV server from defined (configured to the system but not started) to available by specifying in SMIT that the previously configured RPV server should start immediately, which indicates that the RPV server is in the available state.

Use the SMIT menu, Devices, to configure the RPV clients and servers. Before creating RPVs, configure volume groups and logical volumes using the standard AIX® LVM SMIT panels.
