适用于

  • ONTAP 9
  • 自动无中断升级 (ANDU)
  • 崩溃

说明

  • 在 ANDU 期间,可以看到 bug 1465726 的症状
  • 当节点启动关闭时(例如,在 ANDU 触发的接管期间),它会死机:

PANIC: page fault (supervisor read data, page not present) on VA 0x20 cs:rip 0x20:0xffffffff8069859e rflags 0x10046 in process mlogd onrelease 9.10.0P1 (C)

PANIC: page fault (supervisor read data, page not present) on VA 0x448 cs:rip 0x20:0xffffffff806b62b9 rflags 0x10246 in process secd on release 9.11.1P8 (C)

  • ONTAP 主版本 ANDU 期间的数据中断(例如 9.9.1 至 9.11.1P14):

无法托管 LIF:

Sat Apr 22 2023 10:33:01 GMT  [Cluster1-n02: vifmgr: vifmgr.lifbeingremoved:NOTICE]: LIF lif_n01_mgmt (on virtual server 44), IP address 10.250.50.50, is being removed from node Cluster1-n02, port a0l-179.

当发生崩溃的节点再次启动时,将托管 LIF 并恢复数据访问:
