The Dell_diags diagnostics file is written to the following location: /var/log/diags_client location.
The following example shows the process for collecting the OST diagnostic logs (the root user account shown
represents one that resides on the media server, and is not to be confused with a root user account on the DR Series
system):
root@oca3400-74 ~]# ./Dell_diags –collect
Collecting diagnostics...Done
Diagnostics location: /var/log/diags_client//oca3400-74_2012-02-27_23-02-13.tgz
The default log level is set to Error in the OST plug-in, is user-configurable, and can be modified via the DR Series system
CLI or GUI.
Rotating OST Plug-In Logs for Linux
If you set the OST plug-in log level to Debug, this can cause the plug-in log to quickly grow in size. The best practice for
preventing any issues with log sizes is to rotate the OST plug-in logs using the logrotate utility that is commonly available
on Linux-based systems.
To configure log rotation, complete the following:
1.
Create a file in /etc/logrotate.d/, name it “ost”, and add the following entries:
/var/log/libstspiDell.log {
rotate 10
size 10M
copytruncate
}
2.
Create a file in /etc/cron.hourly/, name it “ost_logrotate.cron”, and add the following entries:
#!/bin/bash
/usr/sbin/logrotate /etc/logrotate.d/ost
The logrotate utility runs every hour, and rotates the logs whenever the log file size exceeds 10 megabytes (MB). This
procedure is automated and is available as part of the OST plug-in installation.
Guidelines for Gathering Media Server Information
In addition to the DR Series system diagnostics log file bundles and core files that you can collect for history and
troubleshooting purposes, if you have run any OpenStorage Technology (OST) operations, Dell recommends that you
also gather some important media server-related files. This topic introduces some of these key media server files that
reside on Linux and Windows platforms .
NetBackup on Linux Media Servers
For NetBackup running on a Linux media server, Dell recommends gathering the following files:
•
OST plug-in configuration files and log files from the media server
– Location: /var/log/libstspiDell.log.*
•
NetBackup backup job logs and command logs from the media server:
– Location: NetBackup log files reside in /usr/openv/netbackup/logs/. For each process in NetBackup, there is a
subdirectory in the logs directory. Dell is interested in the following process-related logs: bptm, bpdm, bprd,
bpcd, bpbrm.
– Be aware that these five directories may not exist by default, so only collect these logs if they exist on your
media server. If they were created, the locations where these log files reside are as follows: /usr/openv/
