Environment

vCenter 8.x

Cause

There is EMC_bootbank_emcsplitter present on the cluster which caused the issue as it is not part of the single image for the cluster 

Resolution

Note : Before you begin take a non memory snapshot of vCenter VM (or offline snapshot if part of ELM)

Remove the "IoFilter-EMC_bootbank_emcsplitter" using vCenter mob :

1. Log in to the Managed Object Browser (MOB) using the URL format: https://<VC_IP>/mob.
2. Click Content > groud-d1 (Datacenter) > datacenter-3 (<Datastore-name>) > group-h5 (host).
3. Copy the required cluster name MOID from childEntity.
   For example: domain-c8
4. Click Home > Content > IoFilterManager > QueryIoFilterInfo.
5. Paste the MOID of cluster ex: domain-c8 in place of MOID and click Invoke Method, to view the installed IO Filters:
6. Copy the id value of splitter without double quotations.
   Example: Splitter id: EMC_bootbank_emcsplitter_5330.m.169-1OEM.700.1.0.15843807
7. Run UninstallIOFilter_Task, Home > Content > IoFilterManager > UninstallIOFilter_Task .
8. Paste the ID of splitter or jiraf and give the MOID and click Invoke Method to run uninstallation of splitter.

Once EMC_bootbank_emcsplitter has been removed, attempt the remediation.
