OS 为 5.2
P630 和 7133 连接,如果用户将所有的硬盘都用来做 raid ,例如 6 块盘做 raid5 ,但是在做 raid 配置时,将“ enable use of hot spare ”设置为“ yes ”(缺省设置),如下所示( raid0 和 raid1 和 raid10 类似):
如果该选项设置为“ yes ”,则 SSA RAID Manager 将会用 hot spare disk 来顶替该 raid 中失效的磁盘;如果设置为“ no ”,则该 raid 将不使用 hot spare disk ;如果该选项设置为“ exact ”,只有 hot spare disk 的容量和失效的磁盘的容量完全匹配时才使用该 hot spare disk 。
如果该选项设置为“ yes ”,但是在系统中没有设置 hot spare ,则在系统的 error log 中会报错,信息如下:

用 diag 命令对 SSA 卡进行诊断,报出的错误信息为: SRN 49530 ,通过查资料( SSA Card User Guide and Maintenance Information )可得知,该错误信息的含义是指系统的 hot spare disk 数量的设置低于最小值。因为用户在配置 raid 时将“ enable use of hot spare ”设置为“ yes ”,而并没有在系统中指定 hot spare disk ,所以会报出上述错误信息。只需要更改 raid 中的“ enable use of hot spare ”为“ no ”即可解决上述问题。
注意:“ enable use of hot spare ”选项在缺省情况下是“ yes ”状态。如果没有 hotspare 硬盘,应手动将此项选为“ no ”。
