CRS ban starts automatically once the server is started
crsctl disable crs
Check the server is no longer relevant application process
ps -ef | grep -v root
Check the server connection is no longer relevant
netstat -antlp | grep -i est
Check the server is no longer shared nfs volume

04.OS verification
Verify whether the change in the basic configuration server
Free -g # check whether there are changes in memory, if memory configuration if there are changes, please note that the result of the expected size
cat / proc / cpuinfo | grep physical | uniq -c # to check whether the change in the number of CPU
ip a # backup information and compare whether all IP All mounts
df -h # backup information and compare whether all mounted disks of all, the size of the disk information is correct, if expanded, delete the disk operating verify whether the expected size
route -n # compare routing and backup information is normal
Ntpq -p # check whether the normal start ntp
date # to check whether the normal time
hwclock # time to check whether the correct hardware
The following authentication server for all SAN storage
If multipath -ll # backup information and compare link have lost, if memory related operations to check whether the results in line with expectations
Are sysauto_SF lunuseinfo # compare disk and backup information fully loaded, if storage, ASM disk related operations to check whether the results in line with expectations
Verify that the system is normal, the normal startup volume CRS
crsctl enable crs
crsctl start crs # manually start the CRS
# Observation watch -n 1 "crsctl stat res -t -init" CRS start state
After crsctl check crs # confirm that all start to see whether the status of all online
crsctl stat res -t # Are all the major online resource
05. notification application verification
