5.5.6.3 Hot Plugged Disk For Rebuilding
It defines if the RAID volume should start rebuilding or not when controller
detects a disk is inserted/re-inserted during online. The options are: “Blank Disk
Only”, “Always”, and “Disable”. The default is “Blank Disk Only”.
Blank Disk Only: it will trigger the rebuilding if and only if the inserted disk has
not been in the RAID array before, which has no RAID signature on it. When a
previously removed disk is self re-inserted, it won’t trigger the degraded RAID
array to rebuild, and the administrator has a chance to identify this misbehaving
disk and replaces it.
Always: whenever a disk is inserted/re-inserted whether new or previously
existed, it always trigger a rebuilding for the Degraded RAID set/Volume.
Disable: it will not trigger rebuilding regardless what sort of disk plugging in.
When “Disable” and/or “Blank Disk Only” is selected, the re-inserted/previously
removed disk will be identified as a disk in a separate RAID set with duplicated
RAIDset# and with all the rest of RAID members missing.
5.5.7 HDD Power Management
RAID Controller has automated the ability to manage HDD power based on
usage patterns. The “HDD Power Management” allows you to choose a
“Stagger Power On Control”, “Low Power Idle”, “Low RPM” and completely
“Spins Down Idle HDD”. It is designed to reduce power consumption and heat
generation on idle drives.
