Vsan Upgrade System Ex Perform Vsan Upgrade Preflight Check Ex
Perform an upgrade preflight check on a cluster.
It deprecates API vim.VsanUpgradeSystem.PerformVsanUpgradePreflightCheck, and helps to check following issues which would break vSAN upgrade process:
- Any vSAN host is disconnected from vCenter server
- ESXi host before vSphere 6.0 exists in vSAN cluster, of which on-disk format cannot be upgraded
- Any vSAN host enables auto-mode to claim disk
- Network issue exists in vSAN cluster, which leads to communication problem among vSAN hosts
- Not all vSAN member hosts reside in specified vCenter cluster
- Any vSAN host contributes in the other vSAN cluster
- There is inaccessible vSAN object in vSAN datastore
- Any in-use vSAN disk that are unhealthy, such as physical disk lost
- Hybrid disk group exists in vSAN cluster, and requests to enable Deduplication and Compression
- To request enable Deduplication and Compression, but there is ESXi host software version is below then ESXi 6.0 Update 2
- vSAN downgrade is requested, but vSAN objects have already been upgraded to 2.0 or above
- Any vSAN object that would present an upgrade issue
Any issue detected by preflight check, requires manual fix by end user, before trigger vSAN upgrade process through PerformVsanUpgradeEx.
