VVR Replication: Environment variables used in application migration

In the source and target cluster nodes, configure every disk group that must be migrated with a Storage Replicator Log (SRL) volume. During Rehearse operation, create cache volume in every disk group on the secondary site so that space-optimized snapshots can be created. The application migration plan creates the required SRL volume and cache volume. For creating these volumes, 10% of the used size of the disk group is taken as the default size.

To override the default size of both SRL volume and cache volume, mention the size required for a disk group using specific variables in the appmig.conf file. The file is not present by default. On the node where the disk group is online, create the file in the /opt/VRTSsfmh/etc directory. In the file, define the variable for each disk group.

For example, for a set of service groups to be migrated, if one disk group is online on one node and another disk group is online on another node, create the file for each node and define the variable in the file where the corresponding disk groups are online.

Arctera recommends keeping one copy of the environment file with all necessary entries and copy the same file across all nodes in the source and target clusters.

Note:

Mention the size in megabytes.

Define the following environment variables in the file:

  • SRLVOL_SIZE_DiskGroup

  • CACHEVOL_SIZE_DiskGroup

Example

To specify 1 GB size for SRL volume and 2 GB size for cache volume for disk group dg1, define the variables as follows:

  • SRLVOL_SIZE_dg1 = 1024M

  • CACHEVOL_SIZE_dg1 = 2048M

Scenarios in which the environment file (if created) is read

  • During plan creation from the source cluster node the file checks whether:

    • Sufficient space is available in the source disk group for creating SRL volume.

    • Sum of the size of disks selected for creating disk group in the target cluster is greater than the sum of the used space in the source disk group, plus SRL volume and cache volume size calculated by the plan.

  • During the Setup Storage operation, the SRL volume size is retrieved from the file in the source cluster node and the size is used to create the SRL volume for the disk group in the source and target cluster nodes.

  • During the Rehearse operation, the cache volume size is retrieved from the file in the target cluster node and the size is used to create the cache volume for the disk group in the target cluster node.
