How to shrink your data RAID to fewer physical disks.
To shrink your data RAID set use the RAID menu and press the Shrink button. Note the minimal
number of drives for your selected RAID set. Important: Remember to balance the RAID device after
shrinking by pressing the balance button on the RAID menu.
How to grow your RAID set.
To grow your data RAID set use the RAID menu and press the Grow button. Add available drives to
the RAID set by clicking on the list of available drives. Important: Remember to balance the RAID
device after growing by pressing the balance button on the RAID menu.
How to change your RAID level.
At this time there is no method available for changing a RAID level. If you must have a new RAID
level then:
1. Backup the data.
2. Create a new RAID set with the desired RAID level.
3. Restore the data to the new RAID set.
4. Delete the old RAID set once you are happy that the data was successfully restored.
How to determine if your physical drive is about to fail.
The simple method of seeing a physical drive issue is on the Dashboard. The section marked Drive
Health will give you the first indication of a drive issue. Beyond that you can access the S.M.A.R.T.
information for each drive by:
1. Navigating to the Storage menu and selecting the S.M.A.R.T tab.
2. Selecting a drive from the list.
3. Running a self test on the drive in question. Note some tests can degrade performance and, in
some cases, cause the system to halt. It is best to do these tests when users are offline.
How to assign a new disk as a Hot Spare
A hot spare is a drive that takes over for a failing or failed drive in a RAID set. It is a live drive inserted
in the server and connected to the backplane. The idea behind hot spares is that if you have a drive
fail or one you need to remove then the hot spare takes the place of the drive you are removing
without any loss of time or access to the data.
INFORMATION:
A hot spare needs time to sync/balance with your RAID set after it has been
activated.
Steps for adding a hot spare:
1. Make sure you have an available disk.
2. Go to Storage>RAID
3. Click hot spare. This button is always active.
