A Mirror Cannot be Created for a Database After Failover is Configured

Publication Date:  2012-07-19 Views:  330 Downloads:  0

Issue Description

After failover is configured, you allocate storage LUNs and delete the existing database mirror. When you attempt to add a new database mirror, the error information is displayed.

Alarm Information


Handling Process

Wait for a while, scan for LUNs, and add the database mirror again.

Root Cause

The VTL only allows one database mirror to be configured. If the VTL software is not refreshed after the existing database mirror is deleted, a new database mirror cannot be added. View the log and find that the database has a mirror.
