What Did We Do?

Asystec PM and Technical lead worked closely with the customer’s team to execute the Disk install in 3 phases, each site:


  • Perform full system health check to ensure correct version of SCOS and that the systems were in a healthy state prior to upgrade.
  • Confirm that recent backups had been completed and that an offline phone home has been initiated and collected.


  • Add additional disks in each SCv4020 & SC220.
  • Confirm new disks are detected and present.
  • Perform RAID rebalances.
  • Enable replication & disable maintenance mode.
  • Verify all process are complete and all arrays are error free.


  • Validate all storage is now available to hosts and that volumes can be expanded.
