3.8 Understanding Disks
3.8.1 Disks States
Within the management applications, a disk can be part of one or more arrays and can exist in one
of five states: Online, Offline, New, Legacy, or SMART Error.
 In RAIDXpert2, these states are displayed in the Disk List section in a column named State.
See Table 17, on page 64, for additional information.
 Within the rcadm program, these states are also displayed in a column named State. See Table
41, on page 102, and Table 42, on page 103, for additional information.
The disk states are defined in Table 11.
