Application Notes - Maximizing Efficiency Through Data Replication Manager Data Movement 15
Heterogeneous Configuration Procedures
Whenever configurations are changed or LUNs are created in the data movement procedures that
follow, actions must be taken to enable the hosts to recognize these changes. These actions are
platform specific. The following steps are actions for each operating system currently supported in
your DRM configuration.
1. Compaq OpenVMS: Allow the hosts to recognize new units.
a. If you have shut down the host, boot it. Booting the host enables Compaq OpenVMS to
recognize the drive.
b. If you have not shut down the host, use the following command from a privileged account to
enable OpenVMS to recognize the drives:
MCR SYSMAN IO AUTOCONFIGURE/LOG
2. Compaq Tru64 UNIX: Allow the hosts to recognize new units.
a. If the hosts are shut down, boot them. Booting the hosts enables Tru64 UNIX to recognize the
drives.
b. If the target hosts are not shut down, use the following command to recognize the drives:
hwmgr -scan scsi
This process may take awhile for large configurations. If recognizing the drives takes a long
time, scan only the SCSI bus where one of the DRM host adapters is located with the
following command:
hwmgr -scan scsi -bus x
(where x is the SCSI bus number)
3. IBM AIX: Allow the hosts to recognize new units.
a. If the hosts are shut down, boot them. Booting the hosts enables IBM AIX to recognize the
drives.
b. If the hosts are not shut down, use the following commands to recognize the drives and mount
the file systems:
cfgmgr -v
mount all
4. Microsoft Windows NT: Reboot the hosts and log in using an account that has administrative
privileges. You should be able to see all of the units in My Computer.
5. Microsoft Windows 2000: Reboot the hosts and log in using an account that has administrative
privileges. You should see all of the units by choosing
Computer Management > Disk Management.
