Dell EqualLogic Host Integration Tools for Microsoft Edition Version 5.4 Release Notes

If you are using the native Windows firewall on your failover cluster and you want to use the Dell EqualLogic Multipath I/O DSM, you must configure your firewall to allow ICMP echo requests (pings) for ICMPv4 and ICMPv6. The installation procedure detects the firewall and gives you the option to amend your firewall configuration automatically.

Use the iSCSI Initiator Properties Page Extension to verify that Multipath I/O is working correctly.

If you do not configure the firewall automatically at installation time but you still want to use multipathing, you must configure your firewall manually to allow ICMP requests. The following command-line examples show typical firewall configuration rules:

netsh advfirewall firewall add rule name="Dell EqualLogic MPIO Ping IPv4" dir=in action=allow description="Dell EqualLogic MultiPath I/O Ping rule" enable=yes profile=any localip=any remoteip=any protocol=icmpv4

netsh advfirewall firewall add rule name="Dell EqualLogic MPIO Ping IPv6" dir=in action=allow description="Dell EqualLogic MultiPath I/O Ping rule" enable=yes profile=any localip=any remoteip=any protocol=icmpv6

Refer to the documentation for your version of the Windows operating system for instructions on how to configure a firewall.
