1. 检查共享的NFS权限
   [root@nymtx ~]# id grid
   uid=6001(grid) gid=5001(oinstall) groups=5001(oinstall),5003(asmdba),5004(asmoper),5005(asmadmin)
   [root@nymtx ~]# id oracle
   uid=6002(oracle) gid=5001(oinstall) groups=5001(oinstall),5002(dba),5003(asmdba),5005(asmadmin)

gird 和Oracle同属 asmadmin 组,所以asmadmin要有写限,用以下命令加权限
chmod g+s /asm/*
问题如下:
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=266 device type=DISK
channel ORA_DISK_1: starting datafile backup set restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set

channel ORA_DISK_1: reading from backup piece /oracle/app/oracle/19c/assistants/dbca/templates/Seed_Database.dfb
channel ORA_DISK_1: ORA-19870: error while restoring backup piece /oracle/app/oracle/19c/assistants/dbca/templates/Seed_Database.dfb

ORA-17502: ksfdcre:5 Failed to create file +DATA
ORA-15081: failed to submit an I/O operation to a disk

failover to previous backup

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-03002: failure of restore command at 07/01/2020 01:07:32
ORA-01180: can not create datafile 1

2.DNS 问题是一个BUG可以直接忽略

3.以下IP不需要指定网卡,写在/etc/hosts 中就可以
192.168.1.83 nymtxvip.inno.com nymtxvip
192.168.1.84 hzmtxvip.inno.com hzmtxvip
192.168.1.85 mtscan.inno.com mtscan

4.出现问题要查找日志
/oracle/app/oracle/diag/rdbms/mtxdb/mtxdb1/trace/alert_mtxdb1.log
/oracle/app/oracle/cfgtoollogs/dbca/mtxdb/trace.log_2020-07-01_08-26-16AM
[root@nymtx mtxdb]# pwd
