Synchronizing volume group mirrors

You can use the C-SPOC utility to synchronize shared LVM Mirrors by volume group.

About this task

To synchronize shared LVM Mirrors by volume group using the C-SPOC utility, complete the following steps:

Physical volumes (hdisks) in the volume group must be installed, configured, and all nodes must be available and running the clcomd daemon.
From the SMIT interface, select System Management C-SPOC > Storage > Volume Groups > Synchronize LVM Mirrors > Synchronize By Volume Group and press Enter.
SMIT displays a list of shared volume groups and their owning resource group, if any, and the node list.
Select a volume group and press Enter.
SMIT displays the Synchronize Mirrors by Volume Group panel, with the chosen entries filled in.

Enter values for other fields as follows:

Table 1. Synchronize Mirrors by Volume Group fields
Field	Value
Resource Group Name	SMIT displays the name of the resource group to which this shared volume group belongs.
VOLUME GROUP name	SMIT displays the name of the volume group that you selected to mirror.
Node List	The nodes on which this volume groups is known
Reference node	SMIT displays the node from which the name of the physical disk was retrieved.
Number of Partitions to Sync in Parallel	Leave empty.
Synchronize All Partitions	The default is no.
Delay Writes to VG from other cluster nodes during this Sync	The default is no.

If this panel reflects the correct information, press Enter to synchronize LVM mirrors by the shared volume group. All nodes in the cluster receive this updated information.
