If a storage system is no longer needed, you can remove and disconnect it from Spectrum
Control Base.
About this task
- A removed storage system, along with its storage pools and volumes, can no longer be managed by
the included solution components (see Included cloud interfaces).
- If the removed storage system contains working storage resources and volumes, the information of
these storage pools and volumes is no longer displayed in vSphere Web Client. However, vSphere
data access and service level for these storage pools and volumes is not affected. In addition,
the removed system and its storage resources and volumes can be managed from the standard IBM storage system management tools.
- After the removal, you can add the storage system back again to fully restore its
management.
Procedure
- In the Storage Systems pane, right-click a storage system that you want
to remove, and then select Delete. The confirmation message is displayed.
- Click OK to confirm your action. The storage system is removed.
Important: Do not change VVol-related configuration on Spectrum Control Base, after the
storage system holding the VVol metadata information was detached from Spectrum Control Base, and
then connected again. - If Spectrum Control Base is not registered as a storage provider on vCenter, perform the
registration (this recovers the metadata) and then connect the storage system.
- If Spectrum Control Base is registered as a storage provider on vCenter, wait until vCenter
finishes VASA Provider activation for this storage system (it happens automatically). The activation
is completed after the storage system appears under Spectrum Control Base in the vCenter. To verify
that activation is successful, refresh the Spectrum Control Base GUI. The storage resource that had
been attached to a VVol-enabled service before the storage system was removed, appears as attached
to this service.
