P550 掉电,系统启动后黄灯消除问题
今天机房掉了两次电.致P550(AIX5.3)启动后亮黄灯,用diag运行报以下错误:
The path between the following resources is missing:
U787B.001.DNW4387-
hdisk5 P1-T14-L8-L0 16 Bit LVD SCSI Disk Drive (73400 MB)
U787B.001.DNW4387-
scsi0 P1-T14 PCI-X Dual Channel Ultra320 SCSI Adapter
bus
Select an option to resolve the missing path.
Continue to run diagnostics on the selected resource.
This selection will leave the path in the system configuration.
The path has been removed.
This selection will remove the path from the system configuration.
The path has not been removed.

各位帮忙看看是不是硬盘有问题了,有什么解决办法?先谢了

disk能认到么？vg、lv、fs都还正常么？如果挂载应用都没有问题，就把黄灯关掉再观察吧……收起

我这里前些时也遇到过同样信息，用“errpt -a ”查看提示错误类型为“H”，错误为：硬盘“hdisk0,hdisk1”和阵列卡问题，也是机房停电因起的，我在坛里也发过帖子你可以找下，后来我也用diag 进行消除，可一会儿又亮了，又用命令"/usr/lpp/diagnostics/bin/usysfault -m normal" 还会出现。最后执行diag--Advanced Diagnostics Routines--problem Determination--sysplanar0"提示要重启后，仍会出现，后来坛里的兄弟们看了我传的日志说是硬盘有可能坏了，或者要再插拔下，因为我们这个P550是工作机不想停时间长，所以我当时没有进行停机插拔，那天如果有机会再做，后来系统又出现了页面空间不足的情况，我看网上说修改"lru_file_repage"参数可解决，就执行了"vmo -p -o lru_file_repage=0",奇迹出现了，不但解决了页面空间的问题，而且以前的错误不会再出来了，观察了一个星期，用"errpt -a"从来没出现过任何错误，性能也有所提高。你可以试下，我也不明白当初IBM工程师为什么没有修改这里的参数，造成资源严重浪费，希望对你有帮助!收起
