Depending on your settings and availability of a replacement drive, your
system automatically rebuilds the degraded disk array. See “Rebuilding a
Disk Array” on page 319.
The system sends an Email message about the incident to subscribing
users, depending on user settings. See “Setting User Event Subscriptions”
on page 84.
Disk Array Offline/Logical Drive Offline
Disk arrays are made up of physical drives. Logical drives are created on the disk
array.
When a disk array and its logical drives go Offline, the data stored in the logical
drives is no longer accessible.
Logical drives based on fault-tolerant disk arrays, RAID 1, 1E, 5, 6, 10, 50, and
60, go Offline when two physical drives are removed or fail.
Logical drives based on non-fault tolerant disk arrays, RAID 0, go Offline when
one physical drive is removed or fails.
WebPAM PROe reports these conditions in the following places:
• Dashboard Tab
A red X icon appears beside the disk arrays, logical drives, and physical
drives under System Status.
