config
NAME
config – command for configuration management
SYNOPSIS
config clone <filer> <remote_user>config diff [-o <output_file>] <config_file1> [ <con_fig_file2> ]
config dump [-f] [-v] <config_file>
config restore [-v] <config_file>
DESCRIPTION
The config command is used for managing the configuration of a filer. It allows the user to backup, restore and clone the configuration of a filer.The config clone <filer> <remote_user> command is used to clone the configuration of a filer, filer. Cloning operation reverts back the filer to the old configuration, if something goes wrong. Filer instance specific information like network interface info.(ip address, netmask etc.), /etc/rc file, license codes and serial number etc. are not cloned. The registry key "default.options.clone.exclude” lists the set of prefixes that are not cloned. At present, we are not cloning the keys, whose prefixes match one of the following prefixes: file.contents.rc, file.contents.hosts, options.if, options.hosts, options.license, options.system.hostname, options.vfconfig. We are also not cloning the volume specific configuration(keys in the options.vols.* namespace). After running this command, reboot the filer for the configuration changes to take effect.
The argument remote_user is specified in the following format : username:passwd, where username is the name of the remote user account and passwd is the password of the remote user account.
The config diff [-o <output_file>] <config_file1> [ <con_fig_file2> ] command finds out the differences between the specified configuration files config_file1 and con_fig_file2. It prints out all the key-value pair mismatches in alphabetical order. This command helps the administrators in configuration auditing. This is also useful to compare the configuration files of the partners in a cluster failover setup to detect configuration mismatches. Use -o option to redirect the output of this command to a file output_file.
The config dump [-f] [-v] <config_file> command backs up the filer configuration into the specified config_file. Configuration is stored as a set of name-value pairs in the backup file. By default, this command backs up only the filer specific (head-specific) configuration. Use -v option for backing up the volume specific configuration also. Use -f option for overriding an existing backup file forcefully.
The config restore [-v] <config_file> command restores the filer configuration information from a backup configuration file, config_file. By default, this command restores only the filer specific configuration available in the config_file. Use -v option, for restoring the volume specific configuration also. After running this command, reboot the filer for the configuration changes to take effect.
In some cases, restore operation may not succeed because the previously saved configuration information is no longer valid. For example, a previous configuration included information about a volume that no longer exists or specifies values (e.g., snapshot reserve) that can no longer be met. In these cases, restore operation reverts back the filer to the old configuration.
For this command, config_file can also be specified as a HTTP URL location, to restore the configuration from remote files. But, config dump command doesn’t support backing up the configurations to a remote location. This will be supported in future releases. HTTP URL location is specified in the following format:
http://[remote_user@]host_name[:port]/path_to_the_backup_file where
remote_user specifies the credentials for the basic http authentication and should be in the following form: user_name[:passwd]
hostname is the name of the http server, like www.mycompany.com.
port is the http port value. If this is not specified, default value 80 (default http port) is used.
path_to_the_backup_file specifies the location of the backup file on the http server.
Note: The configuration file argument {config_file} specified in all the above commands can be one of the following types:
a) A simple file name – this would get saved by default as a file in the /etc/configs directory.
b) A full-path file name.
c) Just a `-’. In this case, it indicates either standard input or standard output. This value can only be used with config dump and config restore commands. When used with config dump command, the whole filer configuration is written on to the standard output. When used with config restore command, filer configuration information is read from the standard input.
EXAMPLES
Here are a few examples of the use of the config command.1. Filer> config clone foo1 root:xxxx Clones the remote filer, “foo1′s” configuration on to the filer executing the clone command, i.e. on to “Filer”. 2. Filer> config diff 11_30_2000 Compares the filer’s current configuration with the configuration information available in the backup file /etc/configs/11_30_2000. 3. Filer> config diff 11_30_2000 12_04_2000 Compares the configuration information available in the backup files /etc/configs/11_30_2000 and /etc/configs/12_04_2000. 4. Assume that test1.cfg and test2.cfg are two sample config files with the contents shown below: sample test1.cfg file: options.auditlog.enable=on options.autosupport.enable=off file.contents.hosts.equiv=\\ #Auto-generated by setup Sun May 27 23:46:58 GMT 2001 testfiler1 \\ sample test2.cfg file: options.autosupport.enable=on options.sysconfig.boot_check=on options.sysconfig.boot_errors=console, syslog, autosupport file.contents.hosts.equiv=\\ #Auto-generated by setup Sun May 27 20:12:12 GMT 2001 testfiler2 \\ Following command displays the differences between the above two config files. Filer> config diff test1.cfg test2.cfg ## deleted < options.auditlog.enable=on ## changed < options.autosupport.enable=off --- > options.autosupport.enable=on ## new > options.sysconfig.boot_check=on ## new > options.sysconfig.boot_errors=console, syslog, autosupport ## changed < file.contents.hosts.equiv=\\ #Auto-generated by setup Sun May 27 23:46:58 GMT 2001 testfiler1 \\ --- > file.contents.hosts.equiv=\\ #Auto-generated by setup Sun May 27 20:12:12 GMT 2001 testfiler2 \\ 5. Filer> config dump 11_30_2000 Backs up the filer specific configuration in /etc/configs/11_30_2000. 6. Filer> config dump /home/user/12_04_2000 Backs up the filer specific configuration in /home/user/12_04_2000. 7. Filer> config dump -v 12_12_2000 Backs up the entire filer (filer specific and volume specifc) configuration in /etc/configs/12_12_2000. 8. Filer> config restore 11_30_2000 Restores the filer specific configuration from /etc/configs/11_30_2000. 9. Filer> config restore /home/user/12_04_2000 Restores the filer specific configuration from /home/user/12_04_2000. 10. Filer> config restore -v /home/user/12_04_2000 Restores the entire filer (filer specifc and volume specific) configuration from /home/user/12_04_2000. 11. Filer> config restore http://root:hello@www.foo.com/backup_12_04_2000 Restores the filer specific configuration from a remote file, backup_12_04_2000, available on the http server www.foo.com.
