Creating An Array - Accusys ACUTA User Manual

Creating an array

To create (initialize) an array:
1. Ensure that four drives are installed.
2. Ensure that the RAID level selectors are
correctly positioned for the desired RAID
level.
3. Connect a power cable.
4. Turn on the power switch.
5. Install drives to begin initialization
ACUTA will check the status of the installed drives. If all of four drives are brand new or never
been used in Acuta then the initialization of the desired RAID level array will begin
automatically.
If any one of DISKs you installed has been used in Acuta before, then Acuta will have a
notification on LCD to remind if you really want to initialize a new RAID with previously used
DISK to prevent wrong operation caused DATA loss.
Acuta confirms with you that "Create New RAID" and you can select "Yes" by button to
re-create new RAID or "No" to retrieve existing RAID according to current drives
32
Four drives should usually be installed for initialization to begin. If four
drives are not installed when the power is turned on, the alarm will
sound. A "RAID Fail" message will also display unless:
RAID 5+hot spare has been set
The bottom three drive carriers have drives installed.
In this case, the initialization of a RAID 5 array will take place.
The RAID capacity determined on the RAID level and the capacity of
drives you installed in Acuta , for an example:
If configuring as R5 and install 4 drives each of them are 10 GB, 20 GB,
30 GB, 40 GB to create an array then the total RAID capacity will be 30
GB.
