Name Resolution Problems when Installing
the Cell Manager
During the installation of the Application Recovery Manager Cell
Manager, Application Recovery Manager detects and warns you if the
DNS or the LMHOSTS file is not set up as required. In addition,
Application Recovery Manager notifies you if the TCP/IP protocol is not
installed on your system.
Problem Name resolution fails when using DNS or LMHOSTS
If the name resolution fails, the “error expanding hostname” message
is displayed and the installation is aborted.
• If you encounter resolution problems when using DNS, you get a
warning message about your current DNS configuration.
• If you encounter resolution problems when using LMHOSTS file, you
get a warning message to check your LMHOSTS file configuration.
• If you have not configured either DNS or LMHOSTS, you get a
warning message to enable the DNS or the LMHOSTS resolution in
the TCP/IP properties dialog.
Action Check your DNS or LMHOSTS file configuration or activate it. See the
“Verifying DNS Connections Within Application Recovery Manager Cell”
on page 102.
Problem The TCP/IP protocol is not installed and configured on your
system
Application Recovery Manager uses the TCP/IP protocol for network
communications; it must be installed and configured on every client in
the cell. Otherwise, the installation is aborted.
Action Check the TCP/IP setup. For information, see “Setting Up the TCP/IP
Protocol on Windows Systems” on page B-20.
