这几天发现磁盘非常慢,awr事件发现各种写读等待。今天用orion测试了一下。报告如下:
存储采用双节点(10.2.0.1 on aix 6.1)ds4300:4块10k fc盘做的raid1+0
ORION VERSION 11.1.0.7.0
Commandline:
-run advanced -testname case1 -num_disks 4 -size_small 8 -size_large 8 -type rand
This maps to this test:
Test: case1

1 FILEs found.
Maximum Large MBPS=4.84 @ Small=0 and Large=8
Maximum Small IOPS=879 @ Small=20 and Large=0

没有采用存储交换机,rac结构如下:
检查存储,发现存储存在控制器飘逸现象,原本在raid10在A控制器上,现在转移到b控制器上,附上报错信息。
