Background activities work in conjunction with disk arrays and logical drives. See
“Managing Disk Arrays” on page 158 and “Managing Logical Drives” on page 172
for more information about how and when to use background activities.
Background Activity Management includes the following functions:
• Viewing Current Background Activities (page 184)
