Remove a Spare
The Remove spare opton appears only f you have a a RAID array wth a spare dsk
allocated to t.
Clck Remove spare to start the Remove Spare Wzard and then follow the nstruc-
tons.
You can press F1 to access the onlne help that walks you through the Wzard wth
step-by-step nstructons.
Mgrate an Array
In a tradtonal RAID envronment, when a user wants to change the current state of a
dsk or a current array to a new RAID configuraton, the process of reconfigurng the
new array nvolves multple steps. The user must back up the data, delete the array,
re-boot the PC, and then reconfigure the new array.
MedaSheld RAID allows the end user to change the current state of the dsk or array to
another wth a one-step process called "Mgratng". Ths secton descrbes the NVIDIA
Mgratng process and explans how to use Mgratng to convert from one RAID array
type to another.
General Mgratng Requrements
■ The new array capacty must be equal to or greater than the prevous array.
■ For example, t s possble to mgrate from a RAID 1 array to a RAID 0 array as long
as the RAID 0 array s the same sze as (or larger than) the RAID 1 array.
■ The number of dsks n the new array cannot be less than the number of dsks n
the orgnal array.
■ You cannot mgrate
- To or from a JBOD (Spannng) array
- From RAID 1 to RAID 1
- From RAID 0+1 to RAID 1
- From RAID 5 to 1
Mgratng to an Array Larger Than 2 TB
Your dsks must be parttoned usng the GUID partton table (GPT) f you plan to m-
grate to an array wth greater than 2 TB storage.
If your orgnal array s not a GPT dsk and you expand your array's capacty usng the
mgraton feature to over 2 TB, you wll not be able to access the addtonal storage
above 2 TB n the new array. To use the addtonal storage n ths stuaton, back up your
data, repartton the array usng GPT, then restore your data to the new volume.
Important
Be sure to make the volume dynamc f you plan to have more than four parttons.
