Q
If you encounter a problem while using the RA4000e Series, check this section for help.
1. My Operating System is Linux. I have enabled the over 2TB capacity setting, but I
still cannot partition a device over 2TB in OS. Why?
Ö
The RA4000e Series is over 2TB available, but most OS still cannot support SATA
device to over 2TB capacity. Please refer to the below lost for choosing the OS.
a) Microsoft Windows Vista
2. I have connected the RA4000e Series, but it does not appear in the motherboard
BIOS. Why?
Ö
Ensure that an array is initialized completely.
3.
How should I react to disk failure?
Ö
For a R5/R0+1 array, you should replace the failed disk. Data rebuilding will then
begin.
Ö
For a R5+hot spare array, data will be rebuilt automatically to the hot spare disk. There
is no need to immediately replace the failed drive.
Ö
The capacity of new DISK you installed must equal or larger than the smallest disk in
the RA4000e Series. Otherwise, it will be rejected by the RA4000e Series, though it
has no any damage.
4.
How should I react to a disk failure while creating a RAID5?
Ö
Replace the failed DISK with another of equal or larger capacity. The array will
re-initialize from starting.
5.
If I only have two or three disks, can I create a RAID?
Ö
2 disks: No.
need at least 3 disks to configure R5+hot spare
Ö
3 disks: Yes, but you can only choose R5+hot spare. The three disks must be installed
in the bottom three disk carriers with the top layer – the hot spare location, left empty.
