| CVIPInfo is a diagnostic tool for getting information about the IP
configuration of a machine. It is mostly used to verify the
configuration of multiple network cards to be used with Galaxy. Configuring Galaxy for Multiple Network Interfaces In order for Galaxy to utilize secondary network interfaces, the secondary interfaces must be configured correctly. Galaxy requires that each interface be given a unique name. This name will need to be the primary name for that address. If using host files, this would be the first name after the IP address; if using DNS, it would be the Fully Qualified Domain Name (FQDN) that causes the DNS server to reply (see Note regarding Windows 2000). It is possible to allow one IP address to resolve directly to the machine name; however this address must be bound first so that it is the primary address for the machine. Once the machine's network cards and name/address resolution are correctly configured, Galaxy must be instructed to use the secondary interfaces. This is done through setting pipeline pairs. A pipeline pair is configured at the subclient level; it is an advanced property on the Storage Device Pane. When adding a pipeline pair, it is important to make sure that the interfaces are capable of communicating with each other. Although pipeline pairs are configured at the subclient level, they affect all backups and restores that are done between that Client and MediaAgent. Configuration of one pipeline pair will automatically update all other subclients on that Client that point to the same MediaAgent (not just the storage policy). If multiple pipeline pairs are configured for a Client/MediaAgent, Galaxy will alternate between them. NOTE

|
When CVIPInfo is run without arguments, it lists all the addresses that
are bound to the local machine. It then takes each address and attempts
to do a reverse lookup to find the name for that address. This list of
names is the list of interfaces that Galaxy will display as possible
selections for pipeline pairs. CVIPInfo will then try to find the
primary address for each interface name. This address should match the
address that was resolved back to the interface name; if so, cvipinfo
simply displays a + after the interface name. If the address does not
match, CVIPinfo displays a - after the interface name and prints the
address that was returned. If a interface name is used that did not
resolve back to the correct address, Galaxy will use the second address
listed. Put simply, Galaxy will only correctly use addresses that
displayed a +.
When CVIPInfo has checked all the addresses, it will print a warning report about any problems it encountered. This will include any address that did not have a name entry, names that didn't have address entries, and finally names that had mismatched addresses. CVIPInfo can also look up remote names. This is done by specifying the name to look up as the first parameter on the command line. This can be useful to ensure that two machines know a name as the same address. Using the Utility
Examples
Sample Output Sample 1: Looking up Local Host info for mystery In this sample the both addresses are correctly configured and Galaxy will not have any problems using either address. Sample 2: Looking up Local Host info for GLADIATOR In this sample, none of the secondary addresses are registered in DNS or the host file. Galaxy will list GLADIATOR.commvault.com four times and they will all use 172.19.63.139 to communicate. Sample 3: Looking up Local Host info for mystery WARNING: 1 Interface Names did not resolve back to the correct address In this sample, the second address, which actually has the primary address's name, points back to the primary address. This is due to an incorrect binding order. The address that has the machine name as its own name should be bound before secondary cards. |
