3.7.6.2.
Smart Polling Interval
Besides the scheduled volume check, user can define the Smart Pulling Interval to pull the
SMART status of each disk. The default is "on demand". User can schedule every certain period
of time interval to pull the SMART status of each disk. When SMART pulling is executed, disk
activity will be temporally halted until the SMART parameter reading is finished. It is not
recommend to set the Interval too frequent. Decide based on user applications and experiment
results.
3.7.6.3.
Hot Plugged Disk For Rebuilding
It defines if the RAID array volume should start rebuilding or not when detects a disk is
inserted/re-inserted during online. The options are: "Blank Disk Only", "Always", and "Disable".
The default is "Blank Disk Only".
3.7.7. HDD Power Management
The RAID controller card 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.
"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. So when a previously
removed disk is self re-inserted, it won't trigger the degraded RAID array to rebuild, and
so that the administrator has a chance to identify this misbehaving disk and replaces it.
"Always" – it is what it was before. 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 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.
