4 hard drives
(RAID-5)
•
Provides an operating system and a
single media repository striped across all
drives
• Fault tolerant; if a single drive fails, the
system functions in degraded mode
•
Drive hot-swapping is supported if a
single drive fails
• If an additional drive fails before the first
drive is replaced and the RAID set
rebuilds, data is lost and the system fails
If one drive fails, replace the failed drive as
described in the
“Replacing a Hard Drive”
section on page B-3 .
If multiple drives fail, replace each failed
drive as described in the
“Replacing a Hard
Drive” section on page B-3 . Then, reimage
the system as described in the “Reimaging a
Multiservices Platform Series Device that is
Running VSM” section on page B-5

• Fault tolerant; if a single drive fails, the
system functions in degraded mode
•
If the second drive fails before the first
drive is replaced and the RAID set
rebuilds, data is lost and the system fails
If one drive fails, replace the failed drive as
described in the
“Replacing a Hard Drive”
section on page B-3 .
If multiple drives fail, replace each failed
drive as described in the
“Replacing a Hard
Drive” section on page B-3 . Then, reimage
