一、环境

 OS:

 [root@yitai ~]# lsb_release --all
LSB Version:    :core-3.0-ia32:core-3.0-noarch:graphics-3.0-ia32:graphics-3.0-noarch
Distributor ID: RedHatEnterpriseAS
Description:    Red Hat Enterprise Linux AS release 4 (Nahant Update 7)
Release:        4
Codename:       NahantUpdate7
[root@yitai ~]#

[root@yitai ~]# uname -r
2.6.9-78.ELsmp

RDBMS:

[oracle@yitai ~]$ sqlplus  -version

SQL*Plus: Release 10.2.0.4.0 - Production

oracleasm ：

[oracle@yitai ~]$ oracleasm --version
oracleasm version 2.1.7

软件包：

[root@yitai ~]# ls -l

-rw-r--r--  1 root root 134679 Aug 27 12:38 oracleasm-2.6.9-78.ELsmp-2.0.5-1.el4.i686.rpm
-rw-r--r--  1 root root  13105 Aug 27 12:46 oracleasmlib-2.0.4-1.el4.i386.rpm
-rw-r--r--  1 root root  83636 Aug 27 12:46 oracleasm-support-2.1.7-1.el4.i386.rpm

二、修改之前显示格式:

[oracle@yitai ~]$ /etc/init.d/oracleasm  listdisks
total 0
M512_1
M512_2
M512_3
VOL1
VOL2
VOL3
VOL4

[oracle@yitai ~]$ /etc/init.d/oracleasm  querydisk VOL1
Disk "VOL1" is a valid ASM disk .

三、修改/etc/init.d/oracleasm脚本:

[root@yitai ~]# ls /etc/init.d/oracleasm -l
-rwxr-xr-x  1 root root 7311 Aug 30 07:28 /etc/init.d/oracleasm

  [root@yitai ~]# vi  /etc/init.d/oracleasm  

 listdisks)
   #     "${ORACLEASM}" listdisks -l "${ORACLE_ASMMANAGER}"
   #     ;;
        if [ -d "${ORACLE_ASMMANAGER}/disks" ]
        then
            ls -l "${ORACLE_ASMMANAGER}/disks"
        fi 
        #echo "\${ORACLE_ASMMANAGER} = ${ORACLE_ASMMANAGER}"
        ;;
       

    querydisk)
        shift
        "${ORACLEASM}" querydisk -l "${ORACLE_ASMMANAGER}" -d "$@"
        ;;
   

四、修改之后显示格式：

[root@yitai ~]# /etc/init.d/oracleasm listdisks
total 0
brw-rw----  1 oracle dba 8,  81 Aug 30 06:07 M512_1
brw-rw----  1 oracle dba 8,  97 Aug 30 06:07 M512_2
brw-rw----  1 oracle dba 8, 113 Aug 30 06:07 M512_3
brw-rw----  1 oracle dba 8,  17 Aug 30 06:07 VOL1
brw-rw----  1 oracle dba 8,  33 Aug 30 06:07 VOL2
brw-rw----  1 oracle dba 8,  49 Aug 30 06:07 VOL3
brw-rw----  1 oracle dba 8,  65 Aug 30 06:07 VOL4

[root@yitai ~]# /etc/init.d/oracleasm querydisk VOL1
Disk "VOL1" is a valid ASM disk on device /dev/sdb1[8,17]
