In Exalogic rack, in some cases ZFS heads part rack end up in active-active configuration instead of active-passive configuration which is recommended.
Following is the output of "configuration cluster show" command in ZFS CLI from both the heads. From below output you can see both the heads are Active.
Active-Active it not supported and not recommended for Exalogic. We have to switch ZFS heads part of Exalogic rack to Active-Passive configuration.
