背景：最近发现公司一台惠普服务器异常自动重启了，所以尝试排查下了原因。 排查步骤：1、登录机器，执行last或uptime等命令，查看重启时间 $ last | grep reboot reboot system boot 3.10.0-1160.24.1 Mon Oct 11 19:19 - 10:49 (15:30) reboot system boot 3.10.0-1160.24.1 Wed Oct 6 14:08 - 10:49 (5+20:41) reboot system boot 3.10.0-1160.24.1 Mon Oct 4 13:03 - 10:49 (7+21:46) reboot system boot 3.10.0-1160.24.1 Sun Oct 3 21:39 - 10:49 (8+13:10) reboot system boot 3.10.0-1160.24.1 Sun Oct 3 09:12 - 10:49 (9+01:37) reboot system boot 3.10.0-1160.24.1 Sat Sep 25 23:13 - 10:49 (16+11:36) $ uptime 10:53:27 up 15:34, 1 user, load average: 2.43, 1.74, 1.432、查看系统相关日志（如dmesg、/var/log/messages、kdump等） dmesg：开机日志 $ dmesg | grep -Ei 'error|Fail' [ 0.000000] tsc: Fast TSC calibration failed [ 3.120763] pci 0000:12:00.1: BAR 6: failed to assign [mem size 0x00080000 pref] [ 3.178571] pci 0000:5c:00.0: BAR 6: failed to assign [mem size 0x00200000 pref] [ 3.223819] pci 0000:5d:00.1: BAR 6: failed to assign [mem size 0x00080000 pref] [ 3.240238] pci 0000:5d:00.2: BAR 6: failed to assign [mem size 0x00080000 pref] [ 3.256824] pci 0000:5d:00.3: BAR 6: failed to assign [mem size 0x00080000 pref] [ 3.366034] pci 0000:00:14.0: xHCI BIOS handoff failed (BIOS bug ?) 00012201 [ 4.635351] ioapic: probe of 0000:00:05.4 failed with error -22 [ 4.642051] ioapic: probe of 0000:11:05.4 failed with error -22 [ 4.648757] ioapic: probe of 0000:36:05.4 failed with error -22 [ 4.655459] ioapic: probe of 0000:5b:05.4 failed with error -22 [ 4.662176] ioapic: probe of 0000:80:05.4 failed with error -22 [ 4.668874] ioapic: probe of 0000:85:05.4 failed with error -22 [ 4.675576] ioapic: probe of 0000:ae:05.4 failed with error -22 [ 4.682278] ioapic: probe of 0000:d7:05.4 failed with error -22 [ 4.716010] ERST: Error Record Serialization Table (ERST) support is initialized.

ERST报错可参考说明：https://access.redhat.com/solutions/527433 3、登录服务器的带外管理后台查看下相关日志 因为公司的这台惠普服务器有带外管理页面，所以就直接登录进去看了，带外里面能看到具体的一些硬件报错信息，很方便。 于是进入到带外管理后台的 Integrated Management Log 页面，果然看到有一个CPU类型的硬件报错信息，如下： Uncorrectable Machine Check Exception (Processor 2, APIC ID 0x00000038, Bank 0x00000003, Status 0xBE000000'00800400, Address 0xFFFFFFFF'81637323, Misc 0xFFFFFFFF'81637323).建议是： Update the system firmware. If the issue persists, contact support.Learn more：https://techlibrary.hpe.com/docs/enterprise/servers/gen10/ilo5/en/class0x0005code0x0003-gen10.html 结论就是，这个要找到服务器厂家的售后工程师，协助排查并修复。 |
