How to use kfod(Kernel Files OSM Disk)

kfod(Kernel Files OSM Disk)工具可以用来从操作系统层面模拟发现适用于ASM的Disk,可以从$GI_HOME/bin或$CRS_HOME/bin下面找到她,也可以从安装介质中找到她

在安装GI的时候我们就用到她了(安装的时候kfod会在/tmp的临时目录中)

[root@ohs1 bin]# pwd
/media/stage/ext/bin
[root@ohs1 bin]# echo $LD_LIBRARY_PATH 
/media/stage/ext/lib:
[root@ohs1 bin]# id
uid=0(root) gid=0(root) groups=0(root) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[root@ohs1 bin]# ls
coex  kfod.bin  lsnodes  oifcfg  rdbms  srawutl

如果使用了asmlib,可以通过下列方法找到对应的网络磁盘
