Array Summary Page

This page shows a summary of the arrays in this system. Click an array name to see the array details.

Field
Indicates
Name
The name of the array as assigned by the system.
Health
The current health status of the array; possible health status conditions include:
  • OK
  • Other
  • Error
  • Starting
  • In Service
  • No Contact
  • Lost Communication
  • Damaged
  • Supporting Entity Error
  • Rebooting
  • Restoring Array Defaults
  • Invalid Configuration
Array Hot Spares
The number of array hot spares configured for this array, per tray: The array supports 0 to 8 hot spares per tray.
Segment Size
The associated segment size in kilobytes: 4 KB, 8 KB, 16 KB, 32, or 64 KB. This is an array attribute and must be the same for all virtual disks within an array. Once a virtual disk exists on any of the array's trays (there can be only 0, 1, or 2 virtual disks on a tray), then all of the virtual disks on that array's trays must have the same segment size as that virtual disk. You cannot have pools whose profiles differ in segment size on the same array. You want to avoid configuring unused disks, on the same array, in which no virtual disks can be configured if the pools' profiles do not have the same segment size.
Read-Ahead Mode
Whether the read-ahead attribute is enabled or disabled. This array attribute must be the same for all virtual disks within an array. Once a virtual disk exists on any of an array's trays (you can have 0, 1, or 2 virtual disks on a tray), all of the virtual disks on that array's trays must have a Read-Ahead Mode Enabled setting that matches that virtual disk's Read-Ahead Enabled setting. You must plan the use of the Read-Ahead Enabled setting carefully, because you cannot have pools whose profiles have different Read-Ahead Enabled settings on the same array. You want to avoid configuring a system with unused disks in which no virtual disks can be configured if the pools' profiles do not match the Read-Ahead Enabled setting.
