格式和探测 scsi-all 输出不一致

我的平台：SPARC T4-1 solaris 10 Generic_150400-24 sun4v sparc sun4v

当我在控制台 CLI 上时，磁盘 1 在格式的输出中似乎有所不同，即使相关磁盘在探测 SCSI 所有输出的输出中看起来与其他磁盘相同，下面的 c0t5000CCA07058B9F0d0（输出中的第一个磁盘）可能有什么问题？

我确实看到前面板上的磁盘 LED 与其他的一样是绿色的。

奇怪的是，当我从 CDROM 安装菜单执行 solaris 10 安装时，ZFS 也无法识别该磁盘的容量，它显示 0 MB（我从其他框添加了下面的示例，因此安装菜单中的磁盘名称不同）

─ Select Disks ─────────────────────────────────────────────────────────────────

  On this screen you must select the disks for installing Solaris software.
  Start by looking at the Suggested Minimum field; this value is the
  approximate space needed to install the software you've selected. For ZFS,
  multiple disks will be configured as mirrors, so the disk you choose, or the
  slice within the disk must exceed the Suggested Minimum value.
  NOTE: ** denotes current boot disk

答案1

我以前也遇到过这种情况，根据我的经验，可能是以下两个原因之一：

  1. 该磁盘与其他磁盘略有不同。它的磁盘几何结构略有不同，或者已经存在某种奇怪或损坏的元信息，导致 Solaris 无法正确读取磁盘几何结构

  2. 磁盘已损坏，正在发生故障，或者即将发生故障。

如果磁盘尚未使用，我建议将其替换为另一个。我建议进行格式化/分析读取（或分析写入，如果磁盘上没有有用的数据）以进行全面测试。如果发现任何错误，请更换磁盘。

如果这是供应商（Oracle？）更换的磁盘，请注意，即使它们可能是同一品牌或大小，他们也并不总是使用完全相同的磁盘。即使标签匹配，驱动器的内部结构也可能不同。我过去经常遇到这种情况。
