Cohesity Virtual Edition - expand disk capacity

If you run out of space on your virtual Cohesity below are steps which allow you to extend its capacity.

1. In Cohesity Web UI you can see capacity 534.6 GB

2. SSH to the Cohesity, switch to iris_cli and run: "disk ls" to determine disks size, as you can see we have 50 GB metadata disk and 502 GB data disk

3. Login to ESX or vCentre server and confirm current drives size

4. Expand "Hard Disk 2" metadata disk form 50 to 70 GB and "Hard Disk 3" data disk from 512 to 1024 GB, then restart Cohesity appliance to ensure it can properly recognize the drives new size.

5. SSH to Cohesity, switch to iris_cli, run:

• disk ls - make note of "CURRENT NODE ID"
• disk extend node-id=CURRENT_NODE_ID

Now wait few minutes to allow system to expand disks

6. Run "disk ls" to confirm drives have new sizes as expected

8. Run "cluster restart all-services=true" to allow Cohesity to utilize new capacity

9. While all services are restarted login to Cohesity Web UI to confirm new available capacity
