sundiag收集哪些信息？

sundiag是exadata上收集磁盘信息的利器，这个脚本十分全面，涵盖了与磁盘包括flash盘有关的所有信息。在早期的与HP合作的Exadata V1上不存在这个脚本，从脚本的命名方式就能看出来，是属于收购sun以后的产物。Exadata V1类似的脚本，名字叫GetSCConf.zip , 相比sundiag而言，这个脚本非常简陋，仅仅只能查看cell, lun, physicaldisk, celldisk, griddisk的信息。

在exadata image 11.2.2.2.0版本以后都自带这个脚本，此脚本位于# /opt/oracle.SupportTools/sundiag.sh。Solaris X86也存在对应的版本，收集到的信息与Linux基本一致。

如果您怀疑Exadata机器的磁盘有损坏，例如机器有盘亮黄灯，就可以在这台机器上运行sundiag，完成以后会生成对应的一个压缩包，然后将其上传到SR，供Exadata后台支持工程师分析。在很多硬件相关的SR中，SR工程师通常也要求客户上传sundiag的信息以供诊断。所以掌握 sundiag的使用对于Exadata维护工程师至关重要。一下就是对这个脚本进行简单的分析，看sundiag收集了一些什么信息。

这个脚本本身比较简单，但是涵盖了所有与磁盘相关的信息。

4. 收集了pci的硬件信息以及其十六进制配置信息 lspci
5. 收集了scsi设备信息 lsscsi
6. 收集了分区表的信息 fdisk
7. 收集了目标服务器的系统日志SEL信息
8. 收集SAS磁盘控制器的所有信息，MegaCli64
如果是cell 节点，那么则会额外收集以下信息
9. 收集所有cell的详细信息
10. 收集所有celldisk的详细信息
11. 收集所有LUN的详细信息
12. 收集所有physical disk的详细信息
13. 收集所有非正常状态的physical disk的详细信息
