Deleting an extent
About this task
You can delete one or more unused extents.
Steps
1. From the GUI main menu, do one of the following:
● In a metro node Local:
a. Select Provision Storage.
b. In the View by drop-down, select Extents.
● In a metro node Metro:
a. Select Provision Storage.
b. In the Provision on drop-down, select the cluster of the extent.
c. In the View by drop-down, select Extents.
2. In the Extents view, select the extents to delete, and then click Delete.
3. Review the extents to delete, and then click OK.
4. Review the results of the Delete operation, and then click Close. You can sort the results in the dialog box.
Extent status
The following tables define an extent's Health, Operational, and I/O status.
Health status
Description
OK The extent is functioning normally.
Degraded The extent may be out-of-date compared to its mirror. (This state applies only to extents
that are part of a RAID-1 device.)
Unknown Metro node cannot determine the extent's Health state, or the state is invalid.
Non-recoverable error The extent may be out-of-date compared to its mirror (applies only to extents that are
part of a RAID-1 device), and/or the Health state cannot be determined.
Isolated One or more storage volumes under this mirror is not performing optimally. metro node has
automatically marked the mirrors as isolated to prevent I/O to them.
Operational status Description
OK The extent is functioning normally.
Degraded The extent may be out-of-date compared to its mirror. (This state applies only to extents
that are part of a RAID-1 device.)
Unknown Metro node cannot determine the extent's Operational state, or the state is invalid.
Starting The extent is not yet ready.
I/O status Description
Alive I/O is proceeding normally on the extent.
Dead The underlying storage volume is marked as hardware-dead.
Unreachable The underlying storage volume is unreachable.
