我继承了一个带有两个智能阵列控制器的ProLiant DL360p Gen8:

[...]但是,配置的逻辑驱动器没有显示在SCSI子系统中:
# lsscsi -g

[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 逻辑驱动器最初处于失败状态,我通过以下方式重新启用了该状态:
# hpssacli ctrl slot=1 ld 1 modify reenable在此之后,我认为驱动器将出现在系统中,但它没有显示( dmesg中也没有新消息)。
我还做了一次扫描:
# echo 1 >/sys/class/scsi_host/host2/rescan
# echo 1 >/sys/class/scsi_host/host3/rescan没有效果。
我是否遗漏了一个基本步骤(我还没有重新启动服务器/附件.)?

数组最初的“失败”是什么?这是我想知道在你写问题之前发生了什么的例子之一。
[3:0:0:0] disk HP LOGICAL VOLUME 6.34 - /dev/sg3 你的D 2700‘S逻辑驱动器在那里。也许dmesg | tail会按照modify reenable命令向您显示重扫描信息。我可以肯定地说,reenable开关不是常用的。它不需要在正常操作中使用。所以:
/etc/fstab中查看是否有一个挂载点等待这个逻辑驱动器。https://serverfault.com/questions/765293
