Bug 16964103 About Underlying did Not Available Still Exists if pg in ZC (24582738)

Problem Summary: In some cases, the ASM device group is unable to come online at switchover because the underlying device is not accepting I/O.

Workaround: To restart the application resource group:

  1. Issue cldevice populate from one node of global cluster.

  2. From one node of the zone cluster, restart the application resource group that failed due to no access to storage (for example, clrg restart <rg>).
