Event logs Forward Progress Logs and System Event Logs normally captured by the server management system will not be updated during the firmware update process. IPMI Watchdog During the online complex firmware update process, the IPMI watchdog timeout will be disabled. It will be re-enabled when the system wakes up. The OS will discover the watchdog timer has disappeared after the firmware update process has completed, and will recreate it by design. Partition ID The # getconf _CS_PARTITION_IDENT command (which returns HP-UX partition ID), is used for licensing. It is a concatenation of UUID + nPartition # + vPar #. UUID is continuously available from the SMBIOS table. The latter two (nPartition, vPar #s) are obtained using an IPMI call which may fail during the firmware update process. HP-UX caches this information after the very first call to getconf _CS_PARTITION_IDENT, so this command would only fail if it had never been run before the firmware update process began. Console When the firmware update is in progress, the OS console cannot be serviced on the server management side. Since all active sessions to the OA CLI and GUI interfaces are closed at the beginning of the firmware update process, the OS console cannot be actively viewed during this process. The OS console is normally a quiet interface with little character traffic; however there are conditions (OS panics, for example) where the character buffer could potentially fill up during the firmware update process. If the console character buffer is full during an active online complex firmware update, new incoming characters will be dropped so the console does not hang on the OS side. This potential for console character loss does not extend to kernel memory (dmesg) or impact the OS syslog or crashdump area in any way, so this should not inhibit OS problem diagnosis in the unlikely event something unexpected occurs at the OS level. The characters captured in the buffer will be drained once the firmware update process completes, and console operation will return to normal. Online complex firmware update on Superdome 2 179
