Increase SVM memory to accommodate additional SDS device

When adding additional disks to an SDS, you may need to add additional memory to the SVM.

About this task

After an initial partial population of disks (less than the SDS full capacity), when adding more disks, you may need to add SVM memory. If the SDS doesn't have enough memory, error messages will be displayed.

(You can avoid this procedure by using the deployment wizard to allocate adequate memory during initial deployment.)

Perform this procedure in a maintenance window.

Steps

  1. From the PowerFlex GUI, put an SDS in maintenance mode.
  2. From the vCenter, power off the SVM.
  3. From the vCenter, edit the SVM and increase the SVM memory by 300 MB for each 5 TB of added storage capacity.
  4. Power on the SVM.
  5. From the PowerFlex GUI, remove the SDS from maintenance mode.
  6. Wait for the rebalance to complete.
  7. Repeat the entire procedure for each SVM, one-at-a-time.

Next steps

You can now use any of the PowerFlex management tools to add more drives to the SDS.
