Troubleshooting and Repairing

During the previous business day, a cache drive failed on one of the vSAN OSA nodes. The administrator contacted the manufacturer and received a replacement drive the next day. When the drive failed, vSAN began a resync to ensure data health, and all objects now show a healthy, compliant state. The vSAN administrator must replace the failed cache drive.

Which sequence of steps should the vSAN administrator perform?

  • A Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
  • B Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards, vSAN will rebuild the disk group automatically.
  • C Remove the existing vSAN disk group, and physically replace the device. Then, check to verify that the ESXi host automatically detects the new device. Afterwards, manually recreate the Disk Group.
  • D Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
Explanation

In vSAN OSA, failure of a cache-tier device makes its entire disk group unavailable. The failed disk group must be removed, the replacement device detected by ESXi, and the disk group manually recreated using the replacement cache device and capacity devices. vSAN does not automatically create a new disk group after a cache-device replacement.
