Unstable system after connecting XL-RAID-213SA
Q1.
After installing XL-RAID-213SA, we are unable to start the computer or the computer can not
locate
XL-RAID-213SA upon startup.
A :
1. Please check whether the readings on the XL-RAID-213SA LCD display screen appear
normal.
2. Please check whether the SATA Cable connection cables are properly connected to the
computer system and whether SATA drives are functioning normally.
3. If everything is functioning properly but the user still can not start the computer system,
then the problem might be the system incompatibility. If such incompatibility takes place,
please contact our technical support department.
Q2.
When the XL-RAID-213SA is in use, the computer system is functioning normally but the
XL-RAID-213SA access speed is abnormal.
A :
Please first check whether the XL-RAID-213SA is in the progress of executing data auto-
rebuild.
1. Please examine if the length of the connection cables, SATA cable that connect the
drives to the computer system is too long and whether the specification these cables
complies with the requirements.
2. If both the lengths and specification of the cables are checked out ok, please turn off
XL-RAID-213SA and remove the hard drive from XL-RAID-213SA. Test the hard drive
directly with the computer system since it might be the bad sectors in the hard drive that
are causing the longer than normal system down time.
Hard Drive Failure
Q1.
Under the mirror mode (RAID 1), what will be the system
’
s total storage capacity when
adding a brand new hard drive?
A :
1. The total storage capacity for XL-RAID-213SA is determined by the storage
capacity of the primary hard drive installed during the initial usage.
2. The storage capacity will not increase after initial installation even when place a brand
new hard drive with larger storage capacity.
Q2.
Why does the error message appear when I installed the second hard drive?
A :
1. The storage capacity of the second hard drive must be larger than the first hard drive.
Otherwise, XL-RAID-213SA can not rebuild the new hard drive and the LCD display
screen will display
“
Wrong
Capacity”.
2. The LCD display screen might display rebuilding error messages such as
Pri(s)->Sec(s) or Sec(s)->Pri(s). The term (s) signifies that both hard drives are treated as
original hard drive. The user must determine which hard drive will be the original hard drive
prior installing the hard drives into XL-RAID-213SA. Once the original hard drive is
designated and installed in XL-RAID-213SA, the user can place in the second hard drive by
taking advantage of XL-RAID-213SA
’
s Auto Rebuilding function.
Q3.
My hard drive is obviously operating properly but why is it shown as failed in the
XL-RAID-213SA display?
A :
XL-RAID-213SA uses more strict requirements and standards to examine the bad sectors in
the hard drive. The user can first overwrite the bad sector on a PC before placing the hard
drive into XL-RAID-213SA.
