PDF《LSI SAS控制器驱动报告Invalid》

3 LSI SAS告警信息分析 我们分析一下打印语句的来源 mptbase: ioc0: LogInfo(0x30030501): Originator={IOP}, Code={Invalid Page}, SubCode(0x0501) cb_idx mptctl_reply . 在SAS控制器中断处理过程中,每次都会检查IOCStatus中是否有Log信息.若有Log信息,就打印出 相关Log代码. 00447: static void 00448: m mp pt t_ _r re ep pl ly y(MPT_ADAPTER *ioc, u32 pa) 00449: { 00450: MPT_FRAME_HDR *mf;
