Storage Mirroring Recover uses ICMP pings to monitor the source for failover. A failover
monitor will not be created if ICMP is blocked (although the data and system state will
still be protected). You should configure your hardware to allow ICMP pings between the
source and target. If you cannot, you will have to monitor for a failure manually and
create a dummy monitor at failover time that can be manually failed over. Contact
technical support for assistance with this manual process.
Microsoft Windows ports
Storage Mirroring Recover uses WMI (Windows Management Instrumentation) which
uses RPC (Remote Procedure Call). By default, RPC will use ports at random above
1024, and these ports must be open on your firewall. RPC ports can be configured to a
specific range by specific registry changes and a reboot. See the Microsoft Knowledge
Base article 154596 for instructions.
Storage Mirroring Recover also relies on other Microsoft Windows ports.
● Microsoft File Share uses ports 135 through 139 for TCP and UDP
communications.
● Microsoft Directory uses port 445 for TCP and UDP communications.
These ports must be open on your firewall. Check your Microsoft documentation if you
need to modify these ports.
Hardware ports
You need to configure your hardware so that the Storage Mirroring Recover and
Microsoft Windows ports are open. Since communication occurs bidirectionally, make
sure you configure both incoming and outgoing traffic.
There are many types of hardware on the market, and each can be configured differently.
See your hardware reference manual for instructions on setting up your particular router.
