Dell PowerStore 5200T EMC PowerStore Release Notes for PowerStore OS Version 3 - Page 32

Issue ID MDT-152993 MDT-151804 MDT-146763 MDT-119414 Functional Area Description Workaround/Resolution Virtualization Virtualization Virtualization Virtualization A periodic, automatic cleanup process on vSphere that is performed randomly (every few days) deletes empty config vVols (directories). However, this process also deletes the ISOs folder that is pre-created by PowerStore in case you have not placed any ISO images into the folder. In a PowerStore cluster with multiple VMFS datastores that are mapped to multiple hosts, a performance impact might occur if several VMs are powered off or powered on simultaneously. During a vMotion process, some vVols are deleted. If the VASA provider becomes unavailable during a storage vMotion operation, the deletion of the vVols fails. These vVols are left orphaned and may appear as duplicates. Deploying a VM fails, and checking the vvold.log vCenter log file reveals the following messages: 2019-11-15T05:24:35.161Z info vvold[2112740] [Originator@6876 sub=Default] VVolAbandonedObjectScan::ProcessNamesp ace examining namespace /vmfs/volumes// Recreate the ISOs folder using the following PowerStore CLI command: pstcli -service storage_container -id create_directory -size 100G -name ISOs By default PowerStore creates a 500 GB folder, but you can specify another size if necessary. Refer to the Dell Knowledge Base Article 000320477: Best practices for VMFS datastores - for Bootstorm or Failover with VMware SRM. Delete the orphaned vVols using PowerStore CLI or REST API. Try to deploy the VM again.
