If you want to remove a known, good drive (for example, if
you want to test the system), you must force a rebuild. You have already created a file system
when you first bound the disks. You do not have to create a file system, but you now have to
rebind the disk. Note that in a RAID 5 system with one AIC controller, you have 2 LUNs and 10
bound drives. Five drives are bound to each LUN.
-
Use the Storage Utility application to identify the disk
you want to remove.
-
Right click on the disk in the tree and select Identify
Disk. You will see the “Disk will be forced offline. Do you want to continue?”
-
Click OK. The “Operation successful. You may now
safely remove the drive from the system.” message displays. Note that the LUN is degraded
and the disk is now in a fault state.
-
Use the thumbscrews to remove the bezel, note that all the LEDs for the disks in the
LUN are flashing amber.
-
Remove the drive.
-
Replace the drive.
-
Replace the bezel. This is important, because the fans are in the bezel and you want to
keep the system cool.
-
Select Refresh from the View menu.
-
The Disk is in an Unbound state. One disk in the Bound LUN reads “disk missing.”
-
Click on the disk in the Unbound state.
-
Right click and select Rebuild. You will see a message that reads “Succeeded to
start to rebuild.”
-
Select Refresh from the View menu. There is now no disk in an Unbound
state.
