The systems can access the shared storage.

use or
telnet ping
LLT uses its own protocol, and does not use TCP/IP. So, you must ensure that
the private network connections are used only for LLT communication and
not for TCP/IP traffic. To verify this requirement, unplumb and unconfigure
any temporary IP addresses that are configured on the network interfaces.
The installvcs program configures the private network in the cluster during
installation.
See "About installing and configuring VCS"
You must perform additional network configuration on SuSE. You need not perform
this procedure for the systems that run SLES 10 or later. By default, SLES 10 uses
udev to achieve persistent interface names. Refer to the OS documentation for
information on configuring persistent interfaces on SLES 10.
In rare cases where RedHat does not automatically configure the network
interfaces, RedHat users may also have to perform the network configuration.
Review the following tasks that allow VCS to function properly:
VCS must be able to find the same network interface names across reboots.
VCS must have network interfaces up before LLT starts to run.
Symantec suggests the following steps for configuring network interfaces on
SUSE.
Note: You must not reboot the system between configuring the persistent interface
names and configuring the interfaces to be up before starting LLT.
Note: The MAC address in the ifcfg-eth-id-mac file can be in uppercase or
lowercase. SUSE, and therefore the Veritas product installer, ignores the file with
lowercase MAC address if the file with uppercase MAC address is present.
