我正在尝试查找阵列中磁盘的 SMART 参数，但这种简单的方法似乎不起作用：
% smartctl -d sat --all /dev/sg0 -H

Read Device Identity failed: scsi error unsupported scsi opcode
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

还有其他方法可以查询这些（SATA）磁盘的状态吗？
答案1
你可以做
smartctl -a -l ssd /dev/sda -d cciss,1
或者
smartctl -a -l ssd /dev/sda -d sat+cciss,1
您可以数出最后一个数字然后再选择新的硬盘。
这将导致：
root@pve:~# smartctl -a -l ssd /dev/sda -d cciss,1

答案2
您不必在 HP 服务器上使用 smartctl。
HP 已为这些目的构建了专用工具，因此ssacli和ssaducli实用程序将是最有帮助的。
https://downloads.linux.hpe.com/SDR/project/mcp/
要获取数组状态，类似的方法ssacli ctrl all show config detail可以提供。
