刚学习asm,问题可能有点二,大家不要见笑,自己研究了好久,也没有解决,放到论坛上,ML和大家给看看,指点下! alertASM.txt (17.96 KB, 下载次数: 937)

ORA-15063: ASM discovered an insufficient number of disks for diskgroup "ASMDG"

找不到足够的asm disk数目

应当有4个ASM DISK

action plan:
  1. #! /bin/sh
  2. rm /tmp/kfed_DH.out /tmp/kfed_FS.out /tmp/kfed_BK.out /tmp/kfed_FD.out /tmp/kfed_DD.out /tmp/kfed_PST.out
  3. for i in `ls /dev/raw/raw*`
  4. do
  5. echo $i >> /tmp/kfed_DH.out
  6. kfed read $i >> /tmp/kfed_DH.out
  7. echo $i >> /tmp/kfed_FS.out
  8. kfed read $i blkn=1 >> /tmp/kfed_FS.out
  9. echo $i >> /tmp/kfed_BK.out
  10. kfed read $i aun=1 blkn=254 >> /tmp/kfed_BK.out
  11. echo $i >> /tmp/kfed_FD.out
  12. kfed read $i aun=2 blkn=1 >> /tmp/kfed_FD.out
  13. echo $i >> /tmp/kfed_DD.out
  14. kfed read $i aun=2 blkn=2 >> /tmp/kfed_DD.out
  15. echo $i >> /tmp/kfed_PST.out
  16. kfed read $i aun=1 blkn=2 >> /tmp/kfed_PST.out
  17. done
复制代码
运行以上脚本 并将 /tmp 下 kfed开头的输出文件打包上传
