Note:
Automatic share failover only occurs for standard Windows file system
shares. Other shares must be configured for failover through the failover
scripts or created manually on the target. See Macintosh shares or NFS
Shares for more information.
If you are failing over Windows shares but your source and target do not
have the same drive letters, you must use the All to One selection when
establishing your Storage Mirroring Recover connection. Otherwise, the
shares will not be created on the target during failover.
If a Windows share is created on Windows 2003 with the default full
access permissions (without an ACL) and then failed over, the
permissions given to the target will be read-only permissions.
Windows share information is automatically updated on the target once an
hour. If you need to manually update the share information, click Update
Shares on the main Failover Control Center window after the monitor has
been established.
15. By default, Manual Intervention is enabled, allowing you to control when failover
occurs. When a failure occurs, a prompt appears in the Failover Control Center
and waits for you to manually initiate the failover process. Disable this option only
if you want failover to occur immediately when a failure occurs. This option is not
configurable if the Method to Monitor for Failover is set to No Monitoring.
16. If the Shares selection under Items to Failover is selected, verify that the Use
.SHR Share Mapping File check box is selected if you would like to use the
Storage Mirroring Recover share mapping file to create shares on the target during
failover. If this option is not selected, shares will be created using the information
gathered when the machine was selected as a source to be monitored.
Note:
If the Shares selection under Items to Failover is not selected, shares
will not be failed over to the target regardless of the Use .SHR Share
Mapping File selection.
17. By default, Failover Hostname is disabled. This option automatically removes the
host SPN (Service Principle Name) from Active Directory on the source and adds it
to Active Directory on the target. If you are using Active Directory, enable this
option or you may experience problems with failover.
18. Failback Hostname returns the host SPN on the source and target back to their
original settings on failback. If you are using Active Directory, enable this option or
you may experience problems with failback.
