Troubleshooting Installation
Verifying DNS Connections Within Application Recovery Manager Cell
Chapter 5 103
• To check that a particular Application Recovery Manager client
resolves DNS connections to every Application Recovery Manager
client in the cell properly and vice versa, run:
omnicheck -dns -host <client> [-verbose]
where <client> is the name Application Recovery Manager client
checked.
• To check all possible DNS connections in the cell, run:
omnicheck -dns -full [-verbose]
When the [-verbose] option is specified, the command returns all the
messages. If this option is not set (default), only the messages that are
the result of failed checks are returned.
See the omnicheck man page for more information.
Table 5-1 lists return messages for the omnicheck command. If the
return message indicates a DNS resolution problem, see the online Help
index: “troubleshooting, networking and communication“.
