automatic data placement and automatic load balancing occurs within a pool,
based on the overall workload of the storage hardware resources within
the pool.
NOTE: It is recommended that you keep the OCR mirror and the voting disk mirrors
on a different volume to avoid warning messages during OCR and voting disk
configuration.
Table 6-4 shows a sample volume configuration. Create volumes in
PS5000XV array and create an access list to allow all host iSCSI network
interfaces to access the volumes.
