Document History:
July 9, 2012: Originally published
February 19, 2013: Updated with newer firmware revision and Etrack references

RAID controller firmware in NetBackup 5000, 5020 and 5200 Appliances shipped prior to July 2012 must be updated to prevent a condition where the failure of a single disk could cause a cascading failure on multiple (good) drives. If multiple drives appear to fail it can lead to a forced offlining of the RAID Virtual Disk and other unexpected results, up to and including data loss.


Environment



The following NetBackup Appliances have the potential to be affected: 

  • 5000
  • 5020
  • 5200

Note: NetBackup 5220 Appliances are not affected by this issue.

How to Determine if a 5000 or 5020 Appliance is Affected:
To check firmware version, log into the sysadmin account and issue these commands:

  • admin
  • su
  • /opt/MegaRAID/MegaCli/MegaCli64 -adpallinfo -a0 | grep "FW Version"

Example:
Entering root view, following commands are available...

admin     --Administrator user account
history   --Display the current session's command line history
logout    --Logout the CLI session
network   --Network Management
nodeinfo  --Show storage pool nodes info
PDCLI     --PureDisk Command Line Interface Management
FC        --Fibre Channel management
PureDisk  --PureDisk Management
scsp      --Symantec Critical System Protection
storage   --Storage Management
system    --System Management
vzone     --Virtual Zone Management
IPMI      --IPMI Management
          
example5020-01> admin
Entering admin view, following commands are available...

exit      --Return to root view
history   --Display the current session's command line history
logout    --Logout the CLI session
nodeinfo  --Show storage pool nodes info
password  --Change user password
su        --Change to root access

example5020-01.admin> su
example5020-01:~ # /opt/MegaRAID/MegaCli/MegaCli64 -adpallinfo -a0 | grep "FW Version"
FW Version         : 1.40.322-1445
 

Note: Enter logout twice to log out.

If the value of the last four digits is less than 1650, then the Appliance has the potential to be affected.  A firmware upgrade should be undertaken as soon as possible.
