Resolution

• Please take an offline snapshot and/or backup of all vCenter nodes in the SSO domain. Do not skip this step.
• To rectify this, delete the SMS certificate, unregister the offline providers, and restart the SPS service to register the storage providers with the SHA256 certificate. The below steps can also be used to reset the storage providers for troubleshooting.
• Refer to the resolution section of the following KB with the steps to run the python script "unreg_vasa.py": /storage/log filling up after vCenter upgrade to 7.0u2
• If storage providers do not show up after performing the above steps, try resync, and if resync also fails then check if iofiltervpd service is working on each ESXi host or not.
• Run the below command to check the status of 'iofiltervpd' service on ESXi host -

chkconfig --list | grep iofiltervpd

• If the status of 'iofiltervpd' service is 'off', then run the below command to start the service -

chkconfig iofiltervpd on

• This will fix the issue if storage providers are not coming up after implementing step 1 to step 6 mentioned in the above KB: /storage/log filling up after vCenter upgrade to 7.0u2
