Step by Step: Upgrading the capacity disks in a vSAN 7 Hybrid Cluster

Posted on

My GEN5 Home Lab is ever expanding and the space demands on the vSAN cluster were becoming more apparent.  This past weekend I updated my vSAN 7 cluster capacity disks from 6 x 600GB SAS HDD to 6 x 2TB SAS HDD and it went very smoothly.   Below are my notes and the order I followed around this upgrade.  Additionally, I created a video blog (link further below) around these steps.  Lastly, I can’t stress this enough – this is my home lab and not a production environment. The steps in this blog/video are just how I went about it and are not intended for any other purpose.

Current Cluster:

  • 3 x ESXi 7.0 Hosts (Supermicro X9DRD-7LN4F-JBOD, Dual E5 Xeon, 128GB RAM, 64GB USB Boot)
  • vSAN Storage is:
    • 600GB SAS Capacity HDD
    • 200GB SAS Cache SDD
    • 2 Disk Groups per host (1 x 200GB SSD + 1 x 600GB HDD)
    • IBM 5210 HBA Disk Controller
    • vSAN Datastore Capacity: ~3.5TB
    • Amount Allocated: ~3.7TB
    • Amount in use: ~1.3TB

Proposed Change:

  • Keep the 6 x 200GB SAS Cache SDD Drives
  • Remove 6 x 600GB HDD Capacity Disk from hosts
  • Replace with 6 x 2TB HDD Capacity Disks
  • Upgraded vSAN Datastore ~11TB

Upgrade Notes:

  1. I choose to backup (via clone to offsite storage) and power off most of my VMs
  2. I clicked on the Cluster > Configure > vSAN > Disk Management
  3. I selected the one host I wanted to work with and then the Disk group I wanted to work with
  4. I located one of the capacity disks (600GB) and clicked on it
  5. I noted its NAA ID (will need later)
  6. I then clicked on “Pre-check Data Migration” and choose ‘full data migration’
  7. The test completed successfully
  8. Back at the Disk Management screen I clicked on the HDD I am working with
  9. Next I clicked on the ellipse dots and choose ‘remove’
  10. A new window appeared and for vSAN Data Migration I choose ‘Full Data Migration’ then clicked remove
  11. I monitored the progress in ‘Recent Tasks’
  12. Depending on how much data needed to be migrated, and if there were other objects being resynced it could take a bit of time per drive.  For me this was ~30-90 mins per drive
  13. Once the data migration was complete, I went to my host and found the WWN# of the physical disk that matched the NAA ID from Step 5
  14. While the system was still running, removed disk from the chassis, and replaced it with the new 2TB HDD
  15. Back at vCenter Server I clicked on the Host on the Cluster > Configure > Storage > Storage Devices
  16. I made sure the new 2TB drive was present
  17. I clicked on the 2TB drive, choose ‘erase partitions’ and choose OK
  18. I clicked on the Cluster > Configure > vSAN > Disk Management > ‘Claim Unused Disks’
  19. A new Window appeared and I choose ‘Capacity’ for the 2TB HDD, ‘Cache’ for the 200GB SDD drives, and choose OK
  20. Recent Task showed the disk being added
  21. When it was done I clicked on the newly added disk group and ensured it was in a health state
  22. I repeated this process until all the new HDDs were added

Final Outcome:

  • After upgrade the vSAN Storage is:
    • 2TB SAS Capacity HDD
    • 200GB SAS Cache SDD
    • 2 Disk Groups per host (1 x 200GB SSD + 1 x 2TB HDD)
    • IBM 5210 HBA Disk Controller
    • vSAN Datastore is ~11.7TB

Notes & other thoughts:

  • I was able complete the upgrade in this order due to the nature my home lab components.  Mainly because I’m running a SAS Storage HBA that is just a JBOD controller supporting Hot-Pluggable drives.
  • Make sure you run the data migration pre-checks and follow any advice it has.  This came in very handy.
  • If you don’t have enough space to fully evacuate a capacity drive you will either have to add more storage or completely remove VM’s from the cluster.
  • Checking Cluster>Monitor>vSAN>Resyncing Objects, gave me a good idea when I should start my next migration.  I look for it to be complete before I start. If you have an very active cluster this maybe harder to achieve.
  • Checking the vSAN Cluster Health should be done, especially the Cluster > Monitor > Skyline Health > Data > vSAN Object Health, any issues in these areas should be looked into prior to migration
  • Not always, but mostly, the disk NAA ID reported in vCenter Server/vSAN usually coincides with the WWN Number on the HDD
  • By changing my HDDs from 600GB SAS 10K to 2TB SAS 7.2K there will be a performance hit. However, my lab needed more space and 10k-15K drives were just out of my budget.
  • Can’t recommend this reference Link from VMware enough: Expanding and Managing a vSAN Cluster
