* Where “Nn” means the number of member disks in the new RAID level, “No” means the number of member disks in the
original/old RAID level, “OK” means the migration is always possible, and “N/A” means the migration is disallowed.
2.7.4 Expanding the capacity of logical disks in a disk group
To expand the capacity of a logical disk, do the following:
1. Select Maintenance Utilities > LD Reconfiguration from the main menu.
2. Click Expand and specify the following options for an LD expansion task.
3. Click Apply to view the current settings.
4. Click Confirm. The task is created.
2.7.5 Shrinking logical disks
The shrink operation conducts without background task; it simply reduces the capacity of the logical disk.
To release free space of a logical disk on a disk group, do the following:
1. Select Maintenance Utilities > LD Reconfiguration from the main menu.
2. Click Shrink and specify the following options for an LD shrink task.
Stripe Size (KB) This option must be specified when migrating from a non-striping-based RAID level
to a striping-based RAID level.
Schedule Immediately: The task will start immediately.
Once: The task will start on the specified date and time.
Defragment during
migration
Check this option to allow defragmentation during migration.
DG ID/LD ID Select a DG ID and an LD ID from the drop-down menu for expansion.
Capacity (MB) The capacity of a logical disk can be expanded if there is a free chunk available on
the disk group.
Note
1. The new capacity must be bigger than the current capacity.
2. The sum of increased capacity of all logical disks on the disk group must be less than or equal
to the sum of capacity of all selected free chunks.
Schedule Immediately: The task will start immediately.
Once: The task will start on the specified date and time.
Starting Free Chunk /
Ending Free Chunk
This option specifies the start and end of free chunks to be used for the expansion.
The Ending Free Chunk must be bigger than or equal to the Starting Free
Chunk.
Note
At least one free chunk must be adjacent to the logical disk.
Initialization Option Background / Noinit
Background applies only to the logical disks with parity-based RAID level or
mirroring-based RAID level.
DG ID/LD ID Select a DG ID and an LD ID from the drop-down menu for shrink.
Capacity (MB) Enter the new capacity for the specified logical disk to be shrunk. Note that the new
capacity must be higher than zero.
