Managing Shared Disks

Refreshing the IBM Recoverable Virtual Shared Disk subsystem

The IBM Recoverable Virtual Shared Disk daemon can dynamically refresh the IBM Recoverable Virtual Shared Disk subsystem. This means that nodes and virtual shared disks can be dynamically added or removed from an active virtual shared disk configuration without having to stop all applications and unconfigure the virtual shared disks.

In general, the process for changing an existing virtual shared disk configuration is as follows:

1. Follow the steps for whichever change to your configuration is necessary (adding or removing virtual shared disks and nodes).
2. Make the new information known to the other nodes in the virtual shared disk configuration.
   • Click on the icon of a node that already has the IBM Recoverable Virtual Shared Disk subsystem running
   • Click on Actions>Control RVSD Subsystem...
   • Click on Refresh>OK

The refresh support of the IBM Recoverable Virtual Shared Disk subsystem automatically configures all the virtual shared disks on all the virtual shared disk nodes and starts them.
