ProLiant DL360p Gen8 + P421 + D2700 機箱 + hpsa - 看不到邏輯磁碟設備 (Ubuntu 14.04)

我繼承了帶有兩個 Smart Array 控制器的 ProLiant DL360p Gen8：

# lspci -d '103c:323b' -k
02:00.0 RAID bus controller: Hewlett-Packard Company Smart Array Gen8 Controllers (rev 01)
       Subsystem: Hewlett-Packard Company P420i
       Kernel driver in use: hpsa
04:00.0 RAID bus controller: Hewlett-Packard Company Smart Array Gen8 Controllers (rev 01)
       Subsystem: Hewlett-Packard Company P421
       Kernel driver in use: hpsa

P421 控制器顯然有一個 D2700 機箱插入了一堆配置為 RAID6 的 SAS 驅動器：

# hpssacli ctrl slot=1 show config

但是，配置的邏輯驅動器不會顯示在 SCSI 子系統中：

# lsscsi -g
[2:0:0:0]    disk    HP       LOGICAL VOLUME   6.34  /dev/sda   /dev/sg1 
[2:3:0:0]    storage HP       P420i            6.34  -          /dev/sg0 
[3:0:0:0]    disk    HP       LOGICAL VOLUME   6.34  -          /dev/sg3 
[3:3:0:0]    storage HP       P421             6.34  -          /dev/sg2 

邏輯驅動器最初處於故障狀態，我通過以下方式重新啟用：

# hpssacli ctrl slot=1 ld 1 modify reenable

之後我認為驅動器會出現在系統中，但它沒有（兩者都沒有新消息dmesg）。

我也做了重新掃描：

# echo 1 >/sys/class/scsi_host/host2/rescan
# echo 1 >/sys/class/scsi_host/host3/rescan

沒有效果。

我是否錯過了一個基本步驟（我還沒有重新啟動伺服器/機箱……）？

hpssacli ctrl all show config defailt 這裡的輸出。

陣列最初“失敗”的是什麼？這是我想知道在您寫問題之前發生了什麼的情況之一。

[3:0:0:0]    disk    HP       LOGICAL VOLUME   6.34  -          /dev/sg3 

您的 D2700 的邏輯驅動器在那裡。也許 admesg | tail會根據您的modify reenable命令向您顯示重新掃描資訊。我可以肯定地說，reenable開關不常用。這不是需要在正常操作中使用的東西。所以：

• 為什麼陣列失敗？D2700 是否物理拔出？
• 您希望將其安裝在哪裡？查看/etc/fstab是否有掛載點在等待這個邏輯驅動器。
• 重新啟動*（或幫助我們了解您尚未重新啟動的原因）*。
