Vsan Upgrade System Ex Perform Vsan Upgrade Ex
Start vSAN disk format conversion on a particular cluster.
It deprecates API vim.VsanUpgradeSystem.PerformVsanUpgrade, besides supporting original basic upgrade options, it also supports advanced disk format conversion spec, to convert vSAN disk format to support corresponding vSAN advanced features, such as vSAN deduplication and compression, etc.
In order to perform this on-disk format upgrade, the upgrade process will perform a rolling evacuation/remove/re-add operation to accomplish the upgrade. In other words, one disk group at a time, it will evacuate the data from the disk group, then remove the old format from the now empty disk group, then reformat the disk group with the new format. Once all disk groups have been upgraded, and if the performObjectUpgrade parameter is set, the vSAN object version is also upgraded. Before the object version is upgraded, it is possible to downgrade the cluster by passing the downgradeFormat parameter. Once objects are of the new object version however, downgrade (and thus rollback) are no longer possible. The new object version is required to allow objects to benefit from new vSAN features.
The upgrade process performs additional "preflight checks" before proceeding to upgrade the next host. The upgrade process will be halted if any of those preflight checks fail.
If the upgrade process has been halted due to a problem, or even due to a crash or other failure, it can be re-started at any point in time. The upgrade will resume where it left off and only do the parts that are still outstanding. If the upgrade process stopped after removing vSAN from a disk group, but before re-adding those disks to vSAN, the upgrade process can recover from that. The preflight check results indicate such a condition.
The unique identifier for the managed object to which the method attaches; the serialized managed object reference for a request has the form moType/moId, in this case VsanUpgradeSystemEx/{moId}.
The vSphere release schema. The current specification covers vSphere 9.0.0.0 APIs.
"PerformVsanUpgradeExRequestType Object"The cluster to be upgraded
Required privileges: Host.Config.Storage
After all disk groups have been updated, also upgrade all objects. Once started, rollback of the on disk format is no longer possible. Object upgrade unlocks new vSAN features. The default behavior is upgrading objects is this parameter is not specified.
Perform a on-disk format downgrade instead of upgrade. Only possible if no upgraded objects exist.
Removes the need for one disk group worth of free space, by allowing reduced redundancy during disk upgrade.
Internal debug option meant for functional testing of vSAN upgrades. Skips upgrade on certain hosts and implies performObjectUpgrade being false. Should not be used by customers.
The specification of advanced disk format configuration. The spec cannot be supported in downgrade process, for now we don't have any advanced features supported by lower disk format.
