一些有用的Exadata诊断命令

检测check Exadata Image & OS versions , GI & DB patches

sundiag
exacheck
cellserv ==>  imageinfo
dbhost   ==>  /usr/local/bin/imagehistory 

Also check the version of the switch.

Login to Switch and execute the following command

[root@myswitch-1 sbin]# version

[root@dmorlsw-ib2 sbin]# cd /usr/local/bin
[root@dmorlsw-ib2 bin]# ls -lrt version
-rwxr-xr-x 1 root root 20356 Apr 4 2011 version

Output will look as below.

检测 cell server Cache Policy

cell08#  MegaCli64 -LDInfo -Lall -aALL | grep 'Current Cache Policy'
Current Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU

cell09#  MegaCli64 -LDInfo -Lall -aALL | grep 'Current Cache Policy'
Current Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU

Default Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache Policy: WriteThrough, ReadAheadNone, Direct, No Write Cache if Bad BBU
Cache policy is in WB
Would recommend proactive  battery repalcement.

Example :
a. /opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp  -Cache -LALL -aALL ####( Will list the cache policy)

b. /opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp  -WB  -LALL -aALL ####( Will try to change teh policy from xx to WB)
     So policy Change to WB will not come into effect immediately
     Set Write Policy to WriteBack on Adapter 0, VD 0 (target id: 0) success
     Battery capacity is below the threshold value
