Answer 1

Hi,

How do we connect to the cluster storage, via ISCSI, FC or others?

1. If we are using FC, please check if the HBA card driver is up to date, if not, please update the driver.
2. It's recommended to run Cluster validation at the maintenance time, check if there's any wrong with the cluster storage.
3. Besides, it's recommended to turn to the storage vendor to check if there's anything run, generally, 5120 is related with the storage disk issues. Thanks for your time!
   Best Regards,
   Anne

Answer 4

Hey,

The error you are facing is related to the lost connection to your storage. Storage connectivity should be checked to understand the root cause of the issue. Might help: https://www.dell.com/support/kbdoc/en-us/000138971/cluster-storage-loses-access-to-cluster-shared-volumes

Adding redundant storage can help to avoid this kind of problems. StarWind VSAN can be used to create replicated storage pool for Failover Cluster, which will allow you to increase uptime of the cluster. https://www.starwindsoftware.com/vsan
