用md_restore恢复asm元数据之后...

laobu

请教大家：
用md_restore恢复asm元数据之后，除了recover，是否还可能有其它后续步骤？
总觉得模拟测试不很靠谱的样子
还是实践来的靠谱

1. The options for the md_restore command are described below.
   
2. backup_file - Reads the metadata information from backup_file.
   
3. --silent - Ignore errors. Normally, if md_restore encounters an error, it will stop. Specifying this flag
   
4. ignores any errors.
   
5. --full - Specifies to create a disk group and restore metadata.
   
6. --nodg - Specifies to restore metadata only.
   
7. --newdg -o old_diskgroup:new_diskgroup - Specifies a comma separated list of old diskgroup
   
8. name and new diskgroup names to create a disk group with a different name when restoring
   
9. metadata. The -o option is required with --newdg.
   
10. -S sql_script_file - Write SQL commands to the specified SQL script file instead of executing the
    
11. commands.
    
12. -G diskgroups - Comma separated list of disk groups to be restored. If no disk groups are
    
13. defined, then all disk groups will be restored.
    
14. Examples
    
15. The first example restores the disk group DATA from the backup script
    
16. and creates a copy. The second example takes an existing disk group
    
17. DATA and restores its metadata. The third example restores disk group
    
18. DATA completely but the new disk group that is created is called DATA2.
    
19. The fourth example restores from the backup file after applying the
    
20. overrides defined in the override.sql script file
    
21. ASMCMD [+] > md_restore --full -G data --silent /tmp/dgbackup20090714 ASMCMD [+] > md_restore --
    
22. nodg -G data --silent /tmp/dgbackup20090714
    
23. ASMCMD [+] > md_restore --newdg -o 'data:data2' --silent
    
24. /tmp/dgbackup20090714
    
25. ASMCMD [+] > md_restore -S override.sql --silent /tmp/dgbackup20090714
