Configuring LVM split-site mirroring

Edit online

LVM split-site mirroring is a mechanism that replicates data between the disk subsystems located and configured at two remote sites to ensure disaster recovery. You can use SMIT and C-SPOC to configure mirrored pools that belong to a volume group for LVM split-site mirroring.

Before you configure LVM split-site mirroring, you must complete the following tasks:
  • Plan for implementing LVM split-site mirroring in your environment.
  • Run the PowerHA® SystemMirror® discovery process.
  • Configure all nodes and resource groups.
  • Determine the disk names that are at each location.
  • Verify that forced varyon is set to Yes for all resource groups that contain a volume group for LVM split-site mirroring.
