7.5.4 Handling shared resource connection errors
This subsection explains the handling of shared resource connection errors. Normally, HA Monitor connects shared resources. In the event of a failure, the operator must connect the shared resources manually. This subsection explains how to connect shared resources manually.
For notes about manipulating shared resources, see 7.2.3 Notes about maintaining shared resources. If you do not observe these notes, the shared resources might become corrupted or hot standby processing might fail.

Use the mount OS command to mount the file system.
