Thanx for the response.
There were few occurrences of our SolrCloud cluster where when a primary
went down in a shard, the replica didn't get promoted which eventually led
to downtime. We had to restart zookeeper services (we have three zookeeper
nodes) to promote the replica into primary.
But I
If you have two replicas (one leader/one replica) for each shard of your
collection, and you ensure that no two replicas are on the same node,
and you have three independent Zookeeper nodes, then yes, you should
have HA.

Hi Jack,
Appreciate you helping me to clear this up.
For replicationFactor = 1, that means only keeping one copy of document in
the cluster.
Currently, for our SolrCloud setup, we have two replicas (primary and
replica) per each shard (total of 5 shards). This should achieve the HA
already, cor
There is no HA with a single replica for each shard. Replication factor
must be at least 2 for HA.

Solr Cloud provides HA when you configure at least two replicas for each
shard and have at least 3 zookeepers. That's it. No deck or detail document
is needed.
