New Microcode for 1010

Notification


Risk classification

HIPER (high Impact and/or Pervasive)

Abstract

The latest service pack 1010.22 is now available for system firmware level MH1010.
If you have applied FW1010.20, FW1010.21, or FW1010.22 concurrently a system reboot is strongly recommended. If a reboot is not done, your system could experience an unexpected outage. If a recoverable core event occurs anytime after a concurrent code update has been performed, the system will terminate. A system IPL will eliminate the exposure. 
 
This service pack address HIPER issue.
HIPER/Pervasive: A problem was fixed for loss of memory resources during the system IPL with SRCs BC20E504 and BC20090F logged and memory DIMMs deconfigured. This happens because of an intermittent failure during DIMM initialization. These memory errors can be recovered by clearing all the memory deconfiguration and then doing a re-IPL of the system. The problem has a greater likelihood of occurrence on servers at FW1010.20 or FW1010.21.
