oracle数据库关于GRID的问题，请大佬帮忙

Redhat7.3安装了grid和oracle，安装完成后没问题，如下图，可以正常shutdown immediate以及startup，连接数据库也没问题。

对root操作时，启动关闭都很流畅：
[root@dbserver hz]# srvctl stop db -d tdr
[root@dbserver hz]# srvctl start db -d tdr

[root@dbserver hz]# crs_stat -t
Name Type Target State Host

ora.evmd ora.evm.type ONLINE ONLINE dbserver
ora.ons ora.ons.type OFFLINE OFFLINE
ora.tdr.db ora....se.type ONLINE ONLINE dbserver

问题来了
但是重启虚拟机后就出现问题了，我是先对oracle操作shutdown immediate，然后对root操作reboot。
系统起来之后所有命令都出了问题，百度各种办法也没有解决，请前辈们指教一二。

[root@dbserver hz]# ll /dev/sd*
brw-rw---- 1 root disk 8, 0 Apr 7 23:14 /dev/sda
brw-rw---- 1 root disk 8, 1 Apr 7 23:14 /dev/sda1

brw-rw---- 1 grid asmadmin 8, 32 Apr 7 23:14 /dev/sdc

[root@dbserver hz]# srvctl start db -d tdr
PRCD-1027 : Failed to retrieve database tdr
PRCR-1115 : Failed to find entities of type resource that match filters ((NAME == ora.tdr.db) && (TYPE == ora.database.type)) and contain attributes VERSION,ORACLE_HOME,DATABASE_TYPE
Cannot communicate with crsd

[root@dbserver hz]# crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.

对oracle操作startup时：
SQL> startup;
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DG01/tdr/spfiletdr.ora'
ORA-17503: ksfdopn:2 Failed to open file +DG01/tdr/spfiletdr.ora
ORA-29701: unable to connect to Cluster Synchronization Service

对grid操作时：
[grid@dbserver ~]$ asmcmd
Connected to an idle instance.
sh: /u01/app/oracle/product/11.2.0/dbhome_1/bin/clsecho: No such file or directory
ASMCMD> lsdg
Can't exec "/u01/app/oracle/product/11.2.0/dbhome_1/bin/clsecho": No such file or directory at /u01/app/oracle/product/11.2.0/dbhome_1/lib/asmcmdshare.pm line 494, <STDIN> line 1.

以上，请问各位大神这是哪里出了致命问题，请指教。会不会是我的外挂磁盘sdb和sdc没有做分区？sdb是安装GRID，sdb是数据库用的DG01。
[root@dbserver hz]# lsblk

sda 8:0 0 40G 0 disk
sda1 8:1 0 1G 0 part /boot
