The disk is unmounted and can be safely removed.
2 Remove the hard drive as described in one of the following:
Removing a SATA Hard Drive from the CTERA C200 (on page 12)
Removing a SATA Hard Drive from the CTERA C400 (on page 23)
Removing a SATA Hard Drive from the CTERA C800 (on page 33)
Hot Swapping a Disk in a RAID1, 5, or 6 Array
When using RAID1 (mirroring) or RAID 5/6, you can replace any single hard drive without
losing any of your data. Your data remains available and online during the entire process.
To hot swap a disk
1 Remove the hard drive as described in Safely Removing Hard Drives (on page 84).
2 Install a new hard drive into the vacant slot as described in Installing a SATA Hard Drive
(on page 84).
3 In the Configuration tab's navigation pane, click Main > Dashboard.
The Main > Dashboard page appears.
4 Wait until the array's status is optimal.
Enlarging a RAID1 Array
You can use hot swapping to enlarge a RAID1 array. For example, assume you have two hard
drives, HDD1 and HDD2, in a RAID1 mirroring configuration and in optimal state. The capacity
of HDD1 and HDD2 is 500GB each, meaning the array size is 500GB. You can enlarge the array
to 1TB as follows:
1 Hot swap HDD1, replacing it with a 1TB hard drive as described in Hot Swapping a Disk in
a RAID1, 5, or 6 Array (on page 86).
2 Wait until the array's status is optimal.
3 Hot swap HDD2, replacing it with a 1TB hard drive as described in Hot Swapping a Disk in
a RAID1, 5, or 6 Array (on page 86).
4 Wait until the array's status is optimal.
The array will now be 1TB in size.
You can now enlarge volumes on the array to fill the available space, or add new volumes.
