Enclosure Loss Protection and Drawer Loss Protection

For enclosure loss protection to work, each physical disk in a disk group must be in a separate enclosure. If you set the
enclosureLossProtect parameter to TRUE and have selected more than one physical disk from any one
enclosure, the storage array returns an error. If you set the enclosureLossProtect parameter to FALSE, the
storage array performs operations, but the disk group that you create might not have enclosure loss protection.
Enclosure loss protection is not valid when you create virtual disks on existing disk groups.
The drawerLossProtect parameter defines if data on a virtual disk is accessible if a drawer fails. When you assign
the physical disks, if you set the drawerLossProtect parameter to TRUE and select more than one physical disk
from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter to FALSE,
the storage array performs operations, but the disk group that you create might not have drawer loss protection. You
must set the enclosureLossProtect parameter and the drawerLossProtect parameter to the same value.
Either both the parameters must be TRUE or both must be FALSE. If the enclosureLossProtect parameter and
the drawerLossProtect parameter are set to different values, the storage array returns an error.

Create Disk Pool

Description

This command creates a new disk pool based on the specified parameters. You can create the disk pool by entering
either a list of physical disks or a type of physical disk that you want to use for the disk pool. Each disk pool must be
created from a minimum of 11 physical disks specified. There is no upward limit of physical disks supported in a single
disk pool, but the number cannot exceed the number of physical disks supported on the storage array.

NOTE: If you enter a list of physical disks, ensure that all of the physical disks have the same capacity. If the
physical disks do not have the same capacity, each physical disk in the disk pool reports capacity equal to the
smallest physical disk.
