Audit Logs

  • Steps
    • If audit logging is turned off, enter the following command to turn audit logging on:
    • options auditlog.enable on
    • To change the maximum size of the audit log file, enter the following command:
    • options auditlog.max_file_size value
    • value is the maximum size in bytes. The default value is 10,000,000 (about 10 MB).
    • sending audit logs to a remote log server
      1. First enable syslog to a remote server
      2. enable accepting remote logs on your linux/unix log server
      3. add a line that says: “local7.* @your_log_server” to the netapp’s syslog.conf. reference

Follow the steps for Red Hat:
1. Check the below packages available.
rpm -q device-mapper
rpm -q device-mapper-multipath

2.To start the multipath daemon
# /etc/init.d/multipathd start

3. To configure the DM-Multipath devices

4. Configuring DM-Multipath to start automatically while booting.
chkconfig --add multipathd
chkconfig multipathd on

5. Verify that the multipathd is running

  • ssh to vserver example:
::> security login unlock -username vsadmin -vserver nfs
::> security login password -username vsadmin -vserver nfsEnter a new password:

Enter it again:

::> security login unlock -username vsadmin -vserver nfs

Once you have the vsadmin, login via SSH using vsadmin@vs_mgmt_lif.
