Verifying and synchronizing the GLVM configuration in PowerHA SystemMirror

Edit online

The configuration changes that you have completed to this point need to be synchronized to the other cluster nodes.

Note: When you configure geographically mirrored volume groups, some automatic corrective actions of the PowerHA® SystemMirror® cluster verification utility, such as automatically importing or exporting a volume group, do not work. Therefore, run the automatic corrective action of the cluster verification utility in the Interactive mode.

GLVM for PowerHA SystemMirror Enterprise Edition verifies the configuration and ensures that the following conditions are met. Otherwise, the system issues errors. For some checks, GLVM for PowerHA SystemMirror Enterprise Edition issues a warning. This is indicated in parentheses.

  • The fileset cluster.xd.glvm is installed on all cluster nodes.
  • The RPV site name of the associated geographically mirrored volume group for each node matches its PowerHA SystemMirror site name.
  • From one up to four XD_data networks are defined.
  • A XD_ip network is defined to protect against site isolation. GLVM for PowerHA SystemMirror Enterprise Edition issues a warning if these networks are not configured.
  • There is at least one node at each site in the resource group.
  • All nodes in the resource group have service labels defined on the XD_data network.
  • The inter-site management policy is not Ignore and is either Online on Either Site or Prefer Primary Site.
  • The resource group policy could be either concurrent or nonconcurrent.
  • Each node in the resource group has an RPV server defined for every local physical volume in its geographically mirrored volume group.
  • If there are any geographically mirrored volume groups in the resource group, all volume groups in the resource group are geographically mirrored volume groups.
  • All logical volumes in each PowerHA SystemMirror managed geographically mirrored volume group have the disk allocation policy set to Super Strict.
  • Each PowerHA SystemMirror managed geographically mirrored volume group has a complete mirror copy of all logical volumes at both sites.
  • PowerHA SystemMirror also performs all the existing checks that verify the consistency of the disks, volume groups and file systems configuration across the cluster.
  • In addition, PowerHA SystemMirror performs the existing checks that verify the configuration of the XD_data and XD_ip networks.
