一次asm磁碟頭部資訊丟失故障

一、首先介紹下kfed這個工具配置

kfed這個工具預設是沒有編譯的，需要手工編譯

cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk ikfed

使用kfed dump出裸裝置頭資訊，還是比較容易看懂對應的內容的

$kfed read /dev/drsk/c4t6001438007F3072900008000004A0000d0s6 > disk_header6.txt

$cat disk_header6.txt

二、asm磁碟丟失故障描述

故障環境描述：

作業系統：solaris 10
oracle元件：oracle 11g r2 rac
陣列儲存：asm

故障描述：

2011-09-18，接到領導電話說：湖南資料庫客戶端連不上資料庫，需要進行問題處理。

故障檢查：

1）檢查客戶端tnsnames.ora檔案，配置沒有問題。
2）檢查資料庫crs服務，發現節點172.20.1.6有很多服務沒有起來，於是嘗試重啟crs。在啟動的過程中發現磁碟組ora_data_dg啟動失敗，報錯顯示asm disk "6" 丟失。
3）經常檢查確認 disk "6" 在系統和陣列儲存上都沒有問題，可讀可寫可操作。

啟動crs服務時，asm的報錯資訊如下：

三、使用kfed備份磁碟頭部資訊

1）使用kfed獲取磁碟組ORA_DATA_DG number (4,6) /dev/drsk/c4t6001438007F3072900008000004A0000d0s6頭部資訊

$ kfed read /dev/drsk/c4t6001438007F3072900008000004A0000d0s6 > disk_header6.txt

$ cat disk_header6.txt
