Determining the current configuration for clustered filers
How you check your cluster configuration
There are two ways you can check your cluster configuration prior to placing your cluster online:
- Running the Cluster Configuration Checker script
- Manually, through the command line
Checking options with the Cluster Configuration Checker
The Cluster Configuration Checker is a script that runs under UNIX or as a Common Gateway Interface (CGI) script from a UNIX Web server. It detects the following configuration problems:
- Mismatched licenses
- Mismatched option settings
- Incorrectly configured network interfaces
- Different versions of Data ONTAP on the local and partner filers
You can download this script from the NetApp on the Web (NOW) site at http://now.netapp.com/NOW/tools. Look for the Cluster Configuration Checker (cf-config-check.cgi) file.
To run this script from the command line, complete the following steps.
Step
|
Action
|
|---|
|
1 |
Collect the IP addresses and login information for the local and partner filers.
|
|
2 |
Download the script from the NOW site, then unzip the script.
|
|
3 |
Run the script, as described in the online instructions on the script Web page. You can run the script either from the command line or through a Web browser that can access both filers.
|
|
4 |
Examine the script output and correct any errors or differences identified in the output.
|
Manually checking options and license settings
To check options on the local and partner filers, complete the following steps.
Step
|
Action
|
|---|
|
1 |
View the options set on the local filer by entering the following command at the filer's console:
options
Result
The current option settings on the filer are listed. You should see output similar to the following:
autosupport.doit DONT
autosupport.enable on
.
.
dns.domainname filer1 (might be
overwritten in takeover)
dns.enable off (might be overwritten
in takeover)
ftpd.enable off
.
.
|
|
2 |
Note the values of these options for the local filer, and repeat Step 1 on the partner filer.
|
|
3 |
Verify that the options that have comments in parentheses are set to the same value for both filers. The comments you see are as follows:
- Value might be overwritten in takeover
- Same value required in local+partner
- Same value in local+partner recommended
|
|
4 |
Correct any mismatched options using the following command:
options option_name option_value
|
|
5 |
Check the license settings on both filers using the following command:
license
|
|
6 |
Correct mismatched license settings using the following command:
license option=code
