![nagios check_raid，megacli 报告错误的磁盘容量，C240M5 Cisco 12G 模块化 Raid 控制器 [SAS3516] 上的卷信息。东芝 MG06SCA800A](https://linux22.com/image/769835/nagios%20check_raid%EF%BC%8Cmegacli%20%E6%8A%A5%E5%91%8A%E9%94%99%E8%AF%AF%E7%9A%84%E7%A3%81%E7%9B%98%E5%AE%B9%E9%87%8F%EF%BC%8CC240M5%20Cisco%2012G%20%E6%A8%A1%E5%9D%97%E5%8C%96%20Raid%20%E6%8E%A7%E5%88%B6%E5%99%A8%20%5BSAS3516%5D%20%E4%B8%8A%E7%9A%84%E5%8D%B7%E4%BF%A1%E6%81%AF%E3%80%82%E4%B8%9C%E8%8A%9D%20MG06SCA800A.png)
带有 Cisco 12G 模块化 Raid 控制器 SAS3516 的新型 CiscoC240M5 的 nagios raid_check 出现故障。
目前，我已修改 check_raid 以跳过卷检查部分，仅检查物理驱动器，但理想情况下，我们希望使用 check_raid 检查两者。有人找到解决这个问题的方法吗？或者我应该放弃 check_raid 并使用 megaclisas-status --nagios 的包装器脚本，接受虚拟驱动器大小数字的（表面？）问题？
板载 14 个磁盘，
- RAID1 中的 2* 480 GB Micron_5300_MTFDDAK480TDS
- 12* 8T TOSHIBA MG06SCA800A 处于 RAID10 中，其中 2 个是热备件。
错误：
CRITICAL: megacli:[Volumes(2): DISK0.0:,DISK1.1:; Devices(14): 00,11=Hotspare 03,09,06,12,05,01,08,10,07,04,13,02=Online]
结果是 megacli 命令缺少数据：
# /usr/sbin/megacli -LdInfo -Lall -aall
Adapter 0 -- Virtual Drive Information:
Virtual Drive: 0 (Target Id: 0)
Virtual Drive: 1 (Target Id: 1)
Exit Code: 0x00
来自其他用户的提示
# /usr/sbin/megacli ShowSummary -Aall
另一个问题是，Toshiba MG06SCA800A 8T 磁盘报告的容量为 931.436 GB。这导致虚拟驱动器的总量也相差甚远，报告的容量为 4T，而不是 36T

对于 megaclisas-status 也是一样，因为它使用 megacli。磁盘信息正确，但缺少阵列信息：

storcli 实际上显示了正确的数字，但它不在 hwraid.le-vert.net repo 中，因此它是禁止访问的
