HP OpenView Storage Mirroring User Guide (360226-002, May 2004)

11 - 15
! Shares—Failover is performed on shares.
14. Disable Manual Intervention only if you want failover to occur immediately when a failure occurs.
15. 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 Storage Mirroring share mapping file to create shares on the target machine during
failover. If the Use .SHR Share Mapping File check box is not selected, shares will be created using the information
gathered when the machine was selected as a source machine to be monitored.
16. 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.
17. 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.
18. If you are using Active Directory, click Account and identify a user and the associated password that has update
privileges within Active Directory. This allows SPNs to be created and deleted during failover. Click OK to return to the
Monitor Settings dialog box.
NOTE: 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
connection has been established.
If a share is created on Windows NT 4 or Windows 2000 with the default full access permissions
(without an ACL) and then failed over, the permissions given to the target will be dependent on the
target's operating system. On a Windows 2003 target, the default permission will only be read-only
permission.
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.
Share information is automatically updated on the target once an hour. If you need to manually update the
share information regardless of the
Use .SHR Share Mapping File selection, click Update Shares on the
main Failover Control Center window after the monitor has been created.
Automatic share failover only occurs for Windows shares. Other shares, such as NFS shares or Macintosh
Volumes, must be configured for failover through the failover scripts.
NOTE: If you are using Active Directory, your account password cannot be blank.
