ESXi 8.0 FreeでNVMe SSDの温度を確認する

ESXi 8.0 Free環境で、NVMe SSDの温度が取得できるのかを確認してみた

まず情報源は「Commands to Display S.M.A.R.T. Data for NVMe Devices in ESXi」

S.M.A.R.T.データの読み出しを行うコマンドがある、と

NVMe系コマンド操作で情報取得する場合

まず、NVMeストレージの一覧を確認

[root@esxi:~] esxcli nvme device list
HBA Name  Status  Signature
--------  ------  ---------
vmhba1    Online  nvmeMgmt-nvmhba0
vmhba0    Online  nvmeMgmt-nvmhba1
[root@esxi:~]

この環境には２つのNVMe SSDがあるので、２個表示される

１個目を確認

Composite Temperatureの値はあるが、Temperature Sensorの値が全部なし

これは、怪しいメーカ製のNVMe SSD(TWSC TSC1BN2562DF7T10A)であることに由来していると思われる

じゃあ、２個目(SPD SP7002D2TNGH)は？

「Drive Temperature」に温度は入っている

検証

ここまではNVMe SSDのヒートシンクに向けて冷却ファンが稼働している状態で実行していた

冷却ファンを止めて温度上昇が発生するのかを検証

検索すると「How to enable CIM Server (WBEM service) in ESXi 8」という記事を発見

wbemを有効化すると使えるようになるらしい

まず、現状wbemがどうなっているかを確認

[root@esxi:~] esxcli system wbem get
   Enabled: false
   WS-Management Service: true
   Enable HTTPS: true
   Authorization Model: password
   Port: 5989
   HTTP Procs: 2
   HTTPS Procs: 4
   Provider Procs: 16
   Keepalive Timeout: 1
   Keepalive Max Requests: 10
   Provider Sample Interval: 30
   Provider Timeout Interval: 120
   HTTP Max Content Length: 1048576
   Max Message Length: 40000000
   Thread Stack Size: 1048576

   WS-Management PID: 0
   CIM Object Manager PID: 0
   Enabled SSL Protocols:
   Enabled System SSL Protocols: tlsv1.2
   Enabled Running SSL Protocols:
[root@esxi:~]

「Enabled: false」なので無効状態だった

「esxcli system wbem set -e true」を実行して有効化する

[root@esxi:~] esxcli system wbem set -e true
[root@esxi:~] esxcli system wbem get
   Enabled: true
   WS-Management Service: true
   Enable HTTPS: true
   Authorization Model: password

で、CIMサーバの状態を確認

[root@esxi:~] /etc/init.d/sfcbd-watchdog status
sfcbd-init[1053334]: args ('status')
sfcbd-init[1053334]: Getting Exclusive access, please wait...
sfcbd-init[1053334]: Exclusive access granted.
sfcbd is running
[root@esxi:~]

勝手に起動していた

Web UI上でも起動を確認した

CIMサーバ稼働したので[ハードウェア]-[ストレージ]に情報が表示されるようになったけど、ストレージじゃないなぁ・・・

AMD Zen系CPU温度をとれるAMD Zen4/Zen5 IPMI Thermal DriverをRyzen 5 3500UのESXi 8.0 Freeにインストールしてみた

VMware Flingsを見ていたらAMD Zen4/Zen5 IPMI Thermal Driver なるものがあった

検索してみると「AMD Zen4/Zen5 IPMI Thermal Driver for ESX Fling」という記事を見つけた

それによれば、Zen4/Zen5とかいてあるがZen3も対応しているらしい

もしかしてZen+のRyzen 5 3500Uでも使えるのかな？と実験してみた

実験した環境はGMKtec NucBox G10 mini (Ryzen 5 3500U)環境で、32GBメモリ2枚増設して使っている。

まず、導入前の状態は下記の様になにもデータがない

Flingsからダウンロードしたドライバzipファイルをローカルデータストア上に配置

[root@esxi:/vmfs/volumes/~/iso] ls -l /vmfs/volumes/~/iso/VMware-amd-zen-ipmi_thermal_910.1.0.0006-5vmw.803.0.0.24022510.zip
-rw-r--r--    1 root     root         23355 Jul  8 00:32 /vmfs/volumes/~/iso/VMware-amd-zen-ipmi_thermal_910.1.0.0006-5vmw.803.0.0.24022510.zip
[root@esxi:/vmfs/volumes/~/iso]

ドライバのインストール

[root@esxi:/vmfs/volumes/~/iso] esxcli softwar
e component apply -d /vmfs/volumes/~/iso/VMwar
e-amd-zen-ipmi_thermal_910.1.0.0006-5vmw.803.0.0.24022510.zip
Installation Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Components Installed: VMware-smntemp_910.1.0.0006-5vmw.803.0.0.24022510
   Components Removed:
   Components Skipped:
   Reboot Required: true
   DPU Results:
[root@esxi:/vmfs/volumes/~/iso]

ドライバインストール後はESXi再起動必須

再起動後、ステータスを確認すると、CPU温度を認識するようになった

CLIでも認識するようになった

[root@esxi:~] esxcli hardware ipmi sdr list
Node-Sensor  Description            Entity-Instance  Computed Reading  Base Unit  Raw Reading  Sensor Type  Timestamp/Comment    Raw  Formatted-Raw
-----------  ---------------------  ---------------  ----------------  ---------  -----------  -----------  -------------------  ---  -------------
0.1          Processor 1 CPU0_Tctl  3.1              59                degrees C  59           Temperature  2026-07-08T00:56:20
[root@esxi:~]

元記事ではドライバインストール後に標準では /etc/vmware/default.map.d/smntemp_extra.map ファイルを新規作成して、認識できるようにする必要がある、的な記載があるけどしなくても見れるなぁ・・・

Ryzen 5 3500Uについては /etc/vmware/default.map.d/smntemp.map の方に情報あり、と

[root@esxi:~] lspci -v | grep -A2 '0000:00:18.3'
0000:00:18.3 Bridge Host bridge: Advanced Micro Devices, Inc. [AMD] Raven/Raven2 Device 24: Function 3
         Class 0600: 1022:15eb

[root@esxi:~] cat /etc/vmware/default.map.d/smntemp.map|grep 15eb
regtype=native,bus=pci,id=102215eb..............,driver=smntemp
[root@esxi:~]

どうやら、元記事は1.0.0005時代で、今回インストールしたのは AMD Zen4/Zen5 IPMI Thermal Driver for ESX 1.0.0006 なので、そこの違いである模様

SPAM対応メモ 2026/06/24

メールサーバに新しいメールが入ってこない、というので調査したら、特定ユーザのメールパスワードがばれていてSPAM送信に使われていたという時のメモ

(1) 落ちてるデーモンはいなかった

systemctl --failed

を実行した際に止まっているものはいなかった

(2) メールのキューに異常

postfixのメールキューの状態を確認

# postqueue -p

数万通のメールが滞留していた

差出人はほぼ1ユーザで、宛先は方々にわたる

(3) メール配送停止

ひとまず、postfixのメール配送処理を止める

# postfix abort

(4) ログ確認

/var/log/messagesと/var/log/maillog に対してそのユーザ名でgrepをかけて確認

roudcubeのログにて、roundcube内から多数のメールアドレスを指定してメール送信していることを確認

(5) アクセス者IPアドレス確認

ログから該当する操作のIPアドレスを確認し、そのアドレスがどこなのかを確認

今回は3IPアドレスからきており、どれも海外

(6) あからさまにSPAMを削除

今回特定の時間帯の送信は全部SPAMっぽかったので以下のコマンドで該当ユーザのメールをpostsuper -d queueIDで削除

# for queid in `postqueue -p|grep "Jun 24 04"  |grep ユーザ名|awk '{ print $1 }' | sed s/\*//ig`; do postsuper -d $queid; done

あと、MAILER-DAEMON関連の返送処理も削除

# for queid in `postqueue -p|grep MAILER|awk '{ print $1 }' | sed s/\*//ig`; do postsuper -d $queid; done

(7) とりあえず再開

2026/07/21追記

外部への影響報告

gmailサーバでのメール受信拒否

gmailサーバからメールの受け取り拒否を食らっていました
　https://support.google.com/a/answer/172179

期間は2026/06/23 23:02～2026/07/19ぐらい？(2026/07/21 09:00には問題なかった)

SPFやDMARCなどの設定は正確に実施されているにもかかわらず、gmail側は設定に不備があるから拒否、と言い張る状態でした。

おそらくIPアドレスが同じ場合は、約30日経過しないと許可しないようです・・・

各SPAMレポートサーバでの登録

いくつかのサービスで登録はされましたが、３日程度で削除されていました。

2日程度のメール受信拒否を食らったところ

2日程度でSPAM扱いでメール受信拒否を食らったメッセージが帰ってきたところはこんな感じです

意外だったのは、outlook.com 系から受信拒否を食らってなかったことです

ONTAPシミュレータのaggregateが見えなくなった

ESXi上に構築したONTAP シミュレータでデータ用のaggregateにあるvolumeが見えなくなった

確認したところ、aggregateの状態が「restricted」となっていた

netapp::>

オンラインにできない状態であった

エラーの事例を調べると、wafliron で処理をしてみて、ダメだったら、WAFLで問題おきてて、解決方法がないので、バックアップからリストアしろ、とのこと

storage aggregate wafliron のコマンドを使えるように diagモードとして、状態を確認

netapp::> set diag
