01EH340_001_001 Firmware upgrade New Features and Functions Support for concurrent processor node addition, as well as hot and cold node repair. Support for up to 32 I/O drawers in two powered I/O racks. Support for migrating memory DIMMs from POWER5 model 59x systems to model FHA systems. Support for concurrently connecting an I/O rack to a model FHA system. Support for the 8GB fiber channel adapter, F/C 5735. Support for a virtual tape device. Support for USB flash memory storage devices. Support in the system controller firmware for IPv6. Support in the hypervisor for three types of hardware performance monitors. Support for installing AIX and Linux using the integrated virtualization manager (IVM). On systems running AIX, support was added for an enhanced power and thermal management capability. When static power save mode is selected, AIX will "fold" processors to free processors which can then be put in the "nap" state. System firmware changes that affect all systems A problem was fixed that prevented the default partition environment in the advanced system management interface (ASMI) power on/off menu from being set to "i5/OS" when it was blank. The firmware was enhanced so that SRC B1xx3409, which indicates an invalid state change (such as pushing the power on button twice quickly) will be logged as informational instead of predictive, and will not call home. A problem was fixed that caused a service processor dump to be taken and SRC B181EF88 to be logged, even though the operation of the system was not affected. On systems that are managed by a hardware management console (HMC), a problem was fixed that, under certain rare circumstances, caused SRC B181E411 to be logged, a call home to be made, and a service processor dump to be taken. The firmware was enhanced so that SRC B1812224, which indicates that the user attempted to enable redundancy when the managed system was booting, will be logged as informational instead of predictive. A problem was fixed that prevented error log entries on the secondary service processor (or system controller) from generating a serviceable event on the hardware management console (HMC). A problem was fixed that, under certain rare circumstances, caused SRC B1754202 to be erroneously logged (as a predictive error with a call home) after a disruptive firmware installation. A problem was fixed that caused SRC B1818A0F to be erroneously logged during a firmware installation when service processor (or system controller) failover is disabled. A problem was fixed that prevented the machine type and model data from being added to a node controller's error log entries. On systems with external I/O frames, a problem was fixed that might have prevented the firmware from "unthrottling" processors after entering power save mode. System firmware changes that affect certain systems On systems with the integrated x-series adapter (IXA), a problem was fixed that prevented the creation of a system plan on the HMC. On systems with multiple host channel adapter (HCA) cards, a problem was fixed that logical ports on the HCA cards to be intermittently inactive. In networks using a time server, a problem was fixed that caused the date on a client system to be reset to 1969 if the client system lost power.
