Armdsp-A vaname is suitable for the va7xx0 series. It is said that other products can also be used (you can use armdsp-I to check the VA name)
Amdsp-A vaname is suitable for fc60
Arraydsp-A vaname suitable for autoraid
However, EVA can only be viewed in command view.

HP autoraid
I have to mention that HP's autoraid method has long been applied by HP, but it is still in use.
Autoraid combines RAID 1 and RAID 5. When there is a large amount of space, RAID 1 is used, and RAID 5 is used when there are few;
In addition, there is also the so-called active hot spare, that is, to retain a certain amount of space, as a backup disk, can be a disk, two disks, or multiple disks, that is to say, if one disk crashes, the other active hot spare can be used immediately. However, it is actually distributed across all disks and is a virtual concept.
Let's look at the above:
