Click the
Space Reclamation

thin provisioning pool. Click the
Apply
button to confirm and proceed.

Hot Spares
The XEVO system sets all free disks as a global spare. If one disk drive of the pool fails or has
been removed from any singly redundant RAID, the pool status will change to degraded mode.
At the moment, the XEVO system will search the spare disk to execute pool/volume/data
rebuild into a healthy RAID drive automatically.
5.5.
Disk Roaming
Disks can be re-sequenced in the same system or move all member disks in the same pool from
system-1 to system-2. This is called disk roaming. The system can execute disk roaming online.
Please follow these steps.
1.
Select the
Storage
tab, selects a pool. Click the icon beside the pool name, and then click
the
Deactivate
option.
2.
Click the
Apply
button to apply. The Status changes to Offline.
3.
Move all member disks of the pool to another system.
4.
In the
Storage
tab, select the pool. Click the icon beside the pool name, and then click
the
Activate
option.
5.
Click the
Apply
button to apply. The Status changes to Online.
Disk roaming has some constraints as described in the following.
1.
Check the firmware version of two systems first. It is better for both systems to have the
same firmware version or the firmware version of the system-2 is newer.
2.
All physical disks of the pool should be moved from system-1 to system-2 together. The
configuration of both pool and volume will be kept but LUN configuration will be cleared in
order to avoid conflict with the current setting of the system-2.
