VNX2 how to set a hot backup VNX2

When using unis to create a hot backup disk for the VNX2 generation, you cannot find the menu for creating a hot backup disk according to the VNX1 generation product creation method. How can I set a hot backup disk for the VNX 2 generation storage?

Cause analysis:

VNX2 varies greatly in terms of storage microcodes. It is different from VNX1's hot spare disk setting method, and VNX2 can choose to set a hot spare disk policy.

Solution:

VNX2 sets the hot spare disk location under uniseries in System-Hardware-Hotspare Policy, as shown in the following figure:

 

There are three hot backup policies:

No Hot Spare disk (No Hot Spare): all unused hard disks are Hot Spare disks;

Custom (M): You can set a hot spare disk for each hard disk. Only the Custom policy allows you to select the number of hard disks.

You can define different hot backup policies for different types of disks, as shown in the following figure:
