01ES330_018_018
This level is a disruptive update from the prior level, ES330_018. The system should be powered off before installing this level of system firmware. If this level is installed when the system is running, the CECs will be rebooted, causing all partitions to be terminated, and a reboot will be required.
System firmware changes that affect all model F2A systems:
HIPER A problem was fixed that caused a concurrent firmware installation to hang with SRC BA00E840 being logged. This problem may also cause a partition migration to hang, under certain circumstances, with the same SRC, BA00E840, being logged. This SRC will be logged when this level of firmware is installed and will generate a call home; it should be ignored. It will not be logged during subsequent installations.
HIPER The processor initialization settings were changed to reduce the likelihood of a processor going into an error state and causing a checkstop or system crash.
HIPER A problem was fixed that caused large numbers of enhanced error handling (EEH) errors to be logged against the 4-port gigabit Ethernet adapter, F/C 5740, under certain circumstances.
HIPER A problem was fixed in the hypervisor that might cause a partition migration to fail.
A problem was fixed that caused the /tmp directory on the system controllers and the service processor in the bulk power controller (BPC) to fill up, which results in an out-of-memory condition. When this problem occurred, the system controllers or service processor in the BPC usually performed a reset/reload. This is one possible cause of SRC B1817201 being logged.
A problem was fixed in the repair and verify (R and V) function on the HMC that caused an unnecessary shutdown of the processor node when an error was logged against a bulk power regulator (BPR).
A problem was fixed that caused a partition using a host channel adapter (HCA) or host Ethernet adapter (HEA) to appear to hang (with progress code D200C1FF being displayed) before successfully shutting down. The amount of time the partition appeared to hang depended on the amount of memory assigned to the partition and the usage of HCA or HEA.
A problem was fixed that prevented the HMC from connecting to the managed system if the HMC's DHCP server IP range is changed when the managed system is running.
The firmware was enhanced so that the IDs "celogin1" and "celogin2" allow an authorized service provider to log into the bulk power controller (BPC).
The firmware was enhanced to improve the system memory error recovery.
The firmware was enhanced so that the contents of /tmp are included when a service processor dump is taken.
The firmware was enhanced so that:
1. A failure when writing VPD to a P6 processor will cause the node to be deconfigured rather than terminating the system.
2. The failure of a VPD write operation will not corrupt the VPD table, which may lead to unnecessary system
down-time and unnecessary FRU replacement.
System firmware changes that affect certain model F2A systems:
On systems using QLogic InfiniBand switches, a problem was fixed that caused the PortInfo:linkWidthActive and PortInfo:linkSpeedActive to be inaccurately stored and displayed on the display of subnet parameters.
