The number of disks you can register with one class has the following limitations:
To root class [EFI], you can register up to 100 disks.
To local class or shared class, you can register up to 1024 disks.
There are the following limits to the number of disks that can be connected to one group:
To a mirror group, a maximum of 8 disks and lower level groups can be connected collectively. In other words, a maximum of eight-way multiplex mirroring is supported. However, be aware that the spare disk that will be automatically connected when a disk failure occurs is also included in the count.
To a netmirror group, a maximum of 2 disks can be connected. In other words, a maximum of two-way multiplex mirroring among servers is supported.
To a stripe group, a maximum of 64 disks and lower level groups can be connected collectively. In other words, a maximum of 64-column striping is supported.
To a concatenation group, a maximum of 64 disks can be connected. In other words, a maximum of 64 disks can be concatenated.
To a switch group, a maximum of 2 disks can be connected.
To a mirror group of a root class [EFI], a maximum of 2 disks can be connected.
To a proxy group of a root class [EFI], only one disk can be connected.
