Select File–Set System Configuration to start the array
expansion. The status flag on the array group turns blue and
the flags on the components turn white during the expansion
process. You can perform other activity on the system while
the expansion continues, because the array is fully functional
during the expansion process.
For large arrays, the expansion can take several hours to
complete. Host I/O activity can prolong the expansion process.
If you want to monitor the progress of the expansion
operation, you can use Storage Manager to view the Array
Group Information window. Status is Expanding during the
expansion process, Optimal when it has completed.
Note: If a drive fails during expansion, the expansion may
complete successfully. However, the new, larger array
remains in a degraded state until the problem is fixed. If
there is a hot spare associated with the array, the degraded
array is rebuilt using the hot spare. If there is no hot spare,
replace the defective drive and rebuild the array.
Reconfiguring and Array After Expansion
When the array expansion is complete, you need to configure the
array so that Windows recognizes the additional space. Follow these
steps:
1
Shut down and restart the system.
Note: When restarting, Windows runs chkdsk to verify the
new space.
2
Start Disk Administrator. The new space appears as free space
at the end of the existing logical drive.
3
Select both the original logical drive and the free space by
highlighting both segments.
4
Select Partition–Extend Volume Set... Select Yes when
prompted to save your changes and restart Windows.
