When you assign ownership for disks, you need to follow certain guidelines to maximize fault isolation and to keep automatic ownership assignment working. The guidelines are impacted by your autoassignment policy.
Use these guidelines when you assign ownership for disks:
For example, if your autoassignment policy is stack (the default for most platforms), assign all disks on the same stack or loop to the same node and pool. However, if your autoassignment policy is bay (the default for FAS2xxx models), keep your disks in even-numbered bays and odd-numbered bays homogenous by node and pool.
