1、收集ASM磁盘信息
kfed read /dev/raw3 > /home/grid/kfed_raw3.txt
kfed read /dev/raw4 > /home/grid/kfed_raw4.txt
kfed read /dev/raw5 > /home/grid/kfed_raw5.txt
2、收集2个主要trace
su - grid
cd $ORACLE_BASE/diag/asm/+asm/+ASM*/trace
ls -lrt alert*.log
cd $ORACLE_HOME/log/`hostname`
ls -lrt alert*.log
root用户执行：
crsctl query css votedisk
ocrcheck
ocrcheck -local
ps aux | head -1; ps aux | sort -rnk 4 | head -5
