Workaround These are informational events. When the system is booted up, a type DC event entry is generated in the SEL. When the system is gracefully shut down, one or more type DD event entries are generated in the SEL. Unknown IPMI Type-E1 event Issue The iLO SL (Show Event Logs) menu might report an unknown IPMI Type-E1 event after an OS boot completed event or after an OS graceful shutdown occurred event. Servers HP Integrity BL8x0 i2 Server Blade Workaround You can ignore these unknown IPMI Type-E1 events as they are duplicates of the OS boot completed and OS graceful shutdown occurred events. Network Interface Cards (NICs) Possible performance issues with 10 Gb NICs in systems with greater than 32 physical CPUs Issue On systems with greater than 32 physical CPUs and AD385A-HP PCI-X 266MHz 10Gb Ethernet SR multi-OS cards, under heavy networking traffic an issue with the NDIS driver can cause system sluggishness and performance issues. Servers Superdome SX2000 Workaround HP recommends placing the 10Gb Ethernet cards in the I/O chassis attached to the root cell. Additionally, if the task manager reports high utilization on CPU0, HP recommends that you change the RssBaseCpu registry value for the 10 Gb adapter from CPU0 to a non-zero CPU. See the Microsoft Knowledge Base for instructions. A driver with a workaround will be available soon on http://www.hp.com. AD385A NIC card can affect server performance under a load Issue When handling IPv6 traffic, a server with the Neterion AD385A NIC card installed can exhibit sluggish performance. In some cases, a DPC Watchdog timeout event occurs. Servers Superdome SX2000, rx8640, rx7640, rx6600, rx3600, rx2660 Workaround Set the RssBaseCpu registry value in HLKM\System\CurrentControlSet\ Services\NDIS\Parameters to 8 (the default is 4).

Servers Superdome SX2000, rx8640, rx7640, rx6600, rx3600, rx2660 Workaround Manually reboot the system. HP is aware of this issue.
