How to Collect Diagnostic Data for Hitachi Data Center Analytics Server, Probe Server and RAID Agent
Objective
Diagnostic data collects all the essential logs required to find the root cause of any issue on the Data Center Analytics. It consists of various configuration and log files, to help to resolve the issue. If the issue is not resolved, the generated data file can be sent along with the error messages to the support team for analysis.
As an alternative to capturing the various components separately as described in this article; a simpler method can be used by running the single UNIX getcfg764 script to collect all of the component Diag data, including the JPCRAS collection. Please refer to UNIX Getconfig for more information.
Environment
- Hitachi Data Center Analytics (HDCA)
- All versions
Procedure
HDCA server:
1. In the browser, type the Data Center Analytics server URL https://<ip_address>:<Port-Number>.
2. Log on to Data Center Analytics server.
3. On the Home page, from the Application menu, click Manage.
4. On the Manage window, click the Download Diagnostic Data link.
5. On the Download Diagnostic Data window, click Download to download the file.
Collecting the log file for the Analytics probe server
1. In the browser, type the Analytics probe server URL https://<ip_address>:<Port-Number>.
2. Log on to Analytics probe server.
3. Do steps 3 to 5 from the previous section.
Collecting the log file for the RAID Agent:
To do the following procedure, you must use an OS user account with root user permissions:
1. Log on to the host on which the Analytics Probe server is installed.
2. Run the jpcras command with the following specific information: the information to be collected and the directory in which to store the collected information.
The following is an example of how to run the jpcras command to collect all information and store the collected information in the /tmp/jpc/agt directory: /opt/jp1pc/tools/jpcras /tmp/jpc/agt all all
The collected information is compressed by the tar command and the compress command, and then stored in the specified directory. The file name is as follows:
jpcrasYYMMDD.tar.Z
Where YYMMDD represents the year, month, and date.
Additional Notes
Please reference (MK-96HDCA002-xx) "Hitachi Data Center Analytics User Guide" where -xx = specific version of the HDCA software.
The Unix Getconfig version 7.64 has logic to collect these various components of the HPA environment in addition to other Linux OS configuration and performance data. This getcfg764.tar script can be used instead of the methods described above.
