Whats A Split Brain Condition ? |
|
Answer» SPLIT brain occurs when all the LLT links fails simultaneously. Here systems in the cluster fail to identify whether it is a SYSTEM failure or an interconnect failure. Each mini-cluster thus formed thinks that it is the only cluster thats ACTIVE at the moment and tries to start the service groups on the other mini-cluster which he think is down. Similar thing happens to the other mini-cluster and this may lead to a SIMULTANEOUS access to the storage and can cause data CORRUPTION.
