HP P6000 Replication Solutions Manager Administrator Guide (T3680-96069, June 2012)

Tru64 UNIX
This section describes special procedures for Tru64 UNIX hosts.
Running mount jobs on Tru64 UNIX hosts
When running mount jobs (such as MountHostVolume) on a Tru64 UNIX host, ensure that the
mount point is not placed in a subdirectory of /tmp. Otherwise, the job will hang.
Removing a host agent does not automatically terminate the daemon
Uninstalling an HP P6000 Replication Solutions Manager host agent from a node that is different
from the node on which the host agent is installed on an HP Tru64 UNIX cluster removes the files
but does not terminate the daemon. After removing the host agent, you must manually terminate
the hprsmha daemon.
Windows
This section describes special replication procedures for Windows hosts.
Windows 2003 and Windows 2008 requirements and considerations
HP P6000 DC-Management is not supported on dynamic volumes.
Configuring Windows and Linux systems with multiple network interface cards
Installing the replication manager host agent on a host with multiple network interface cards (NICs)
can require changing the IP binding order.
To configure a host with multiple NICs:
1. Modify the SERVER_NAME_IP parameter in hprsmha.cfg with a specific IP address.
2. Uncomment the hprsmha.cfg file before restarting the host agent service.
By default, the host agent will bind to all IP addresses available on the server.
Failing over DR groups for Windows hosts
Before a planned failover of DR groups in a Windows environment, ensure that all Windows
cached data has been flushed. Small files left in Windows cache can disrupt remote replication.
Reboot the host if requested.
In order to fail over DR groups in asynchronous mode, a transition should take place to synchronous
mode in order to synchrnize all outstanding data from the source to the target.
NOTE: Making a snapclone of the target site in asynchronous mode does not guarantee data
consistency.
Sizing the Windows System Event Log
The Windows Removable Storage service and multipath software can generate entries in the host's
System Event Log for each mount and unmount operation by the replication manager. Multipath
software can also report path failures during device removal. These entries do not indicate a
problem and can be ignored. If mount and unmount activity is heavy, the number of log entries
can be significant. Keep this in mind when sizing a Windows System Event Log in replication
manager implementations.
Avoiding device pop-ups on Windows hosts
When the replication manager mounts a host volume, a Windows host may display a pop-up
window indicating that Windows has installed new devices and that the system must be restarted
for the changes to take effect. It is not necessary to restart the host. Click No to close the pop-up.
