IssueHow to perform a nightly Linux RAID configuration backup on RSA NetWitness and RSA Security Analytics appliances.
Resolution

RSA Support recommends that the hardware RAID configuration of all NetWitness appliances be backed up on a daily basis to allow for easy recovery in the event of a RAID hardware failure and to avoid data loss.


 


In order to configure the nightly backup, follow the steps below.


  1. Download the attached nwraidbackup.sh file from this article.
  2. Use scp or another file transfer client to move the file to your RSA NetWitness appliance.
  3. Copy the file to /usr/sbin with the following command:  cp nwraidbackup.sh /usr/sbin
  4. Verify that the script is executable with the following command:  chmod +x /usr/sbin/nwraidbackup.sh
  5. Run this command:  ln -s /usr/sbin/nwraidbackup.sh /etc/cron.daily/nwraidbackup

 


The configuration of all hardware RAID controllers will now be backed up into an archive file as /var/raidbackup/raidbackup-<DATE>.tar.bz2.  The following are the contents of a sample backup archive:



raidbackup-2012.06.19-16.43.05/
raidbackup-2012.06.19-16.43.05/adapevents.out
raidbackup-2012.06.19-16.43.05/adap0-PERCH700Integrated.cfg
raidbackup-2012.06.19-16.43.05/ldpdinfo.out
raidbackup-2012.06.19-16.43.05/adaplist.out
raidbackup-2012.06.19-16.43.05/adap1-MegaRAIDSAS8888ELP.cfg
raidbackup-2012.06.19-16.43.05/pdlist.out
