问题描述

合作伙伴节点经历了自动接管，以下内容可以在EMS-LOG-FILE

callhome.sfo.takeover:alert]: Call home for CONTROLLER TAKEOVER COMPLETE AUTOMATIC

cf_takeover: callhome.reboot.takeover:notice]: Call home for PARTNER REBOOT (CONTROLLER TAKEOVER)

cf_takeover: cf.fm.takeoverComplete:notice]: Failover monitor: takeover completed

splog_main: mgr.boot.reason_abnormal:EMERGENCY]: System rebooted due to a power glitch. splog_main: callhome.reboot.glitch:notice]: Call home for REBOOT (power glitch)

货架还报告了电源故障，见 EMS-LOG-FILE

cf_hwassist: cf.hwassist.takeoverTrapRecv:notice]: hw_assist: Received takeover hw_assist alert from partner(cluster1-01), system_down because power_loss. dsa_worker5: ses.status.psWarning:error]: DS224-12 (S/N SHF#############) shelf 0 on channel 7a power warning for Power supply 2: warning status; DC undervoltage. This module is on the rear of the shelf at the bottom right. dsa_worker4: ses.status.psWarning:error]: DS224-12 (S/N SHF#############) shelf 10 on channel 9d power warning for Power supply 2: warning status; DC undervoltage. This module is on the rear of the shelf at the bottom right.

Sat Jan 11 00:30:40 +0100 [snes1p208_01: dsa_worker0: callhome.shlf.power.intr:error]: Call home for SHELF POWER INTERRUPTED

ASUP HA 组通知还显示以下内容

HA Group Notification (CHASSIS POWER SUPPLY DEGRADED: PSU3) ERROR

HA Group Notification (CHASSIS POWER DEGRADED: Power Supply Status Critical: PSU3.) ERROR

HA Group Notification (SHELF POWER INTERRUPTED) ERROR

HA Group Notification (SHELF_FAULT) ERROR

检查SP-LATEST-SYSTEM-EVENT-LOG 可以看到以下内容：

Record 407: Fri Feb 28 03:34:17.489482 2020 [Agent.notice]: 127.880: 3 : AC Power Loss Signal PSU1 de-asserted Record 408: Fri Feb 28 03:34:17.489664 2020 [Agent.notice]: 128.100: 4 : AC Power Loss Signal PSU2 de-asserted Record 409: Fri Feb 28 03:34:17.557708 2020 [Agent.notice]: 196.145: 4 : AC Power Loss Signal PSU2 asserted Record 410: Fri Feb 28 03:34:17.570049 2020 [Agent.notice]: 208.526: 3 : AC Power Loss Signal PSU1 asserted Record 411: Fri Feb 28 03:34:17.635848 2020 [Agent.notice]: 274.301: 14 : Attention LED (at Midplane) asserted Record 412: Fri Feb 28 03:34:23.431854 2020 [Agent.notice]: 070.290: 14 : Attention LED (at Midplane) de-asserted Record 413: Fri Feb 28 03:34:27.516634 2020 [SP.warning]: AC_OK Low Detected Record 419: Fri Feb 28 03:39:47.942198 2020 [SP.critical]: Filer Reboots

两个节点的电源同时丢失，不会发生接管。然后将直接执行重新启动。
