检查asm磁盘的权限是否问题,发现磁盘权限正常
[root@jtp3 ~]# ls -lrt /dev/asm* brw-rw----. 1 grid oinstall 8, 128 Apr 3 2018 /dev/asmdisk07 brw-rw----. 1 grid oinstall 8, 48 Apr 3 2018 /dev/asmdisk02 brw-rw----. 1 grid oinstall 8, 96 Apr 3 2018 /dev/asmdisk05 brw-rw----. 1 grid oinstall 8, 112 Apr 3 2018 /dev/asmdisk06 brw-rw----. 1 grid oinstall 8, 64 Apr 3 2018 /dev/asmdisk03 brw-rw----. 1 grid oinstall 8, 80 Apr 3 2018 /dev/asmdisk04 brw-rw----. 1 grid oinstall 8, 32 Apr 3 2018 /dev/asmdisk01
