Issue



A newer version of the RAID firmware for NetBackup 5220 Appliances is available which resolves several issues.

A defect has been identified in the RAID firmware stack which prevents the controller from coming ready when a device reset is issued from the device driver. The RAID controller is not completing the online controller reset (OCR) sequence.

A RAID Fatal Firmware error may be encountered on the Intel SROMBSAS RAID Controller under a specific set of circumstances. This RAID Controller hosts the internal RAID 6 Virtual /Storage Disk. When this error occurs, the RAID Controller and the RAID 6 Virtual Disk will no longer be seen in the Appliance Operating System and NetBackup.  Backup jobs will fail.

Finally, aging battery backup units (BBUs) are affected by an issue which causes incorrect status reporting.  This new firmware also contains an enhancement that prolongs the life of aging BBUs.


Error



Several errors may be observed relating to the above issues.

1. An incorrect absolute state of charge of the BBU is reported - for example:

Relative State of Charge: 100 %
Charger System State: 49168
Charger System Ctrl: 0
Charging current: 0 mA
Absolute state of charge: 3808 %

2. Fatal firmware errors are logged - for example:

Event Description: Fatal firmware error: Line 334 in ../../i2c/i2cArbitrator.c

String: Line 334 in ../../i2c/i2cArbitrator.c

or

Event Description: Fatal firmware error: Line 252 in ../../raid/mtask.c

_monTask: Online Controller Disabled  0  0 

How to determine if Affected:
To check firmware version, log into the CLISH menu and issue these commands:

  • Support
  • MegaCli Run
  • -adpallinfo -aall | grep "FW Version" | grep "1.40"

Examine the final number in the firmware version returned - versions prior to 2004 have the potential to be affected by this issue.
