How to calculate and increase Available Assets for Replication Gateway Pairs in Veritas Resiliency Platform
Description
Each asset in Veritas Resiliency Platform (VRP) uses 6 GB of storage space from the secondary disk in each Replication Gateway.Here's the formula:
Examples:
- If you present a 50 GB disk to both gateways, then the pair will be able to handle 4 assets.
- 50 GB secondary disks / 6 GB per asset = 8 available assets (with 2 GB left over on each secondary disk)
- 100 GB secondary disks / 6 GB per asset = 16 available assets (with 4 GB left over on each secondary disk)
To increase the number of available assets in the Replication Gateway:
1. In the VRP Datamover KLISH, check the size of the staging storage disk that the Datamover is using:
manage > staging-storage list-used-disk
2. In the VMWare console, edit the Datamover appliance VM settings to increase the size of the VMDK file used for the staging disk. Click OK to accept the changes.
3. In the VRP Datamover KLISH, increase the size of the staging disk volume:
manage > staging-storage resize-logicalvolume
4. Answer "y" to resize the Staging-Storage Volume.
5. Confirm that the size has changed:
manage > staging-storage list-used-disk
For older VRP Datamover appliances that do not have the "manage > staging-storage" KLISH option:
2. Use the CLISH (Command line menu shell on the appliance) to perform this operation:
a. settings> lvm remove-disk
b. Follow the menu options to replace the secondary disk and specify the new disk
All the data that was on the original secondary disk will be copied to the new, larger disk.
When completed, the original, smaller secondary disk may be removed.
After completing the steps above to increase the size of the secondary cache disks, the available assets will be automatically adjusted in VRP.
