Symptoms

在啟動 ESXi 7.0 後,安裝了大量網路介面卡 (NIC) 的伺服器注意到 NIC 連接埠上的連結中斷。

網卡組態如下:

TSR 中的乙太網路清單

分析:

  1. 在 BIOS 中執行迴路測試,確認功能可搭配插槽 7 網路卡使用。
  2. 已收集作業系統記錄並分析 vobd 記錄中,發現對應至 VMNIC16 和 17 的插槽 7 port3 和 port4 並未註冊為裝置。
  3. 檢查 VMkernel 記錄並找到對應的十六進位 ID b4:00.3 報導”failed to allocate 64 MSIX interrupts.」

作業系統版本:

  • VMware ESXi 7.0.3 組建-23794027
  • VMware ESXi 7.0 U3

Cause

ESXi 未偵測到所有的 vmnic 適配器,但是,那些 vmnic 配接卡出現在「lspci“而不是在 esxcfg-nics -l. 

vmkernel.log 檔案中,您會看到類似以下內容的項目:

xxxx:xx:xx.x failed to allocate 64 MSIX interrupts

因應措施:
要變通解決此問題,請調整引導選項”maxIntrCookies」以增加中斷限制。

“ 的預設值”maxIntrCookies」取決於使用中的 ESXi 版本,以及進階設定值是否在主機升級至 ESXi 版本 8 之前手動設定得更高,其中預設值已提高。  

  • ESXi 版本 7.x「maxIntrCookies」的預設值設定為 1024
  • ESXi 版本 8 中的預設值已增加到 4096。
 
注意:最大中斷 Cookie 的上限為 4096,即使將其 > 設置為 4096 的值也是如此。
