Follow these steps to expand a Storage Pool.
Before you begin
Before you expand a Storage Pool, the following preconditions must be met:
- Upgrade all Accesser® nodes and Slicestor® nodes to release 3.6.0 or later.
- Approve a number of Slicestor nodes equal to a
multiple of the least common multiple of all the vault IDA widths for the vaults that use the
Storage Pool to be expanded. If you are using Concentrated Dispersal, you can expand by using either the Concentrated Dispersal set size or an integer multiple of the full IDA
Width.
Note: If you reimaged a Slicestor
appliance to expand a storage pool, the device might not be available for use immediately after
approval. The Slicestor appliance can be used when the
device starts publishing a valid "Storage Engine" and "Total Size" to the Manager.
Procedure
-
In the Configure tab, click Storage Pools in the
left navigation panel.
-
Click the Storage Pool to replace a device. The Storage Pool:
<Pool Name> page displays.
-
In the Slicestor Devices section, click
Change Sets and Devices.
-
In the Expand Storage Pool section, click Configure Storage Pool
Expansion.
-
From the Width drop-down menu under the General
bar, select the IDA Width for the expanded Storage Pool.
-
Select the Slicestor devices to be used to expand
this pool.
These devices are used to form a new Device Set within this Storage
Pool.
-
If you know the devices you want to add, filter devices by storage engine, model, or site,
then select the Slicestor devices for the new
device set.
Note: Available filters can vary based on system configuration.
-
If you don't know the devices you want to add, click Suggest Devices to
allow the Manager application to select Slicestor
devices on your behalf.
- Click Save. The new set is now part of the storage pool "pending
addition."
- If additional set expansions are to be added, repeat steps 3-7. If
other set changes are to be configured, perform those. Otherwise, from the Slicestor Devices section
click Start Reallocation. A confirmation page appears.
