oracle 11g 使用ASM存储迁移

一、环境描述 rhel 6.6 + Oracle 11.2.0.4 存储更换，需要添加新盘，替换掉旧的存储盘，以下为测试步骤。二、测试过程 [root@roidb1 ~]# cd /etc/udev [root@roidb1 udev]# ls makedev.d rules.d udev.conf [root@roidb1 udev]# cd rules.d/ [root@roidb1 rules.d]# ls 55-usm.rules 60-pcmcia.rules 70-persistent-net.rules 98-kexec.rules 60-fprint-autosuspend.rules 60-raw.rules 90-alsa.rules 99-oracle-asmdevices.rules 60-openct.rules 70-persistent-cd.rules 90-hal.rules [root@roidb1 rules.d]# cat 99-oracle-asmdevices.rules KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB134477b8-eb4c906a", NAME="asm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB02fff4da-d0a0c3a3", NAME="asm-diskc", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VBdfa1c4b9-379f6810", NAME="asm-diskd", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB47ca97bf-4f2e68c0", NAME="asm-diske", OWNER="grid", GROUP="asmadmin", MODE="0660" [root@roidb1 rules.d]# [root@roidb1 rules.d]# ##添加一块新盘 [root@roidb1 rules.d]# scsi_id --whitelisted --replace-whitespace --device=/dev/sdf 1ATA_VBOX_HARDDISK_VBf00cea14-af091329 [root@roidb1 rules.d]# [root@roidb1 rules.d]# [root@roidb1 rules.d]# [root@roidb1 rules.d]# ls 55-usm.rules 60-pcmcia.rules 70-persistent-net.rules 98-kexec.rules 60-fprint-autosuspend.rules 60-raw.rules 90-alsa.rules 99-oracle-asmdevices.rules 60-openct.rules 70-persistent-cd.rules 90-hal.rules ##修改配置文件 [root@roidb1 rules.d]# vi 99-oracle-asmdevices.rules KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1AT A_VBOX_HARDDISK_VB134477b8-eb4c906a", NAME="asm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660"Â Â Â Â Â KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1AT A_VBOX_HARDDISK_VB02fff4da-d0a0c3a3", NAME="asm-diskc", OWNER="grid", GROUP="asmadmin", MODE="0660"Â Â Â Â Â KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1AT A_VBOX_HARDDISK_VBdfa1c4b9-379f6810", NAME="asm-diskd", OWNER="grid", GROUP="asmadmin", MODE="0660"Â Â Â Â Â KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1AT A_VBOX_HARDDISK_VB47ca97bf-4f2e68c0", NAME="asm-diske", OWNER="grid", GROUP="asmadmin", MODE="0660"Â Â Â Â Â KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1AT A_VBOX_HARDDISK_VBf00cea14-af091329", NAME="asm-diskf", OWNER="grid", GROUP="asmadmin", MODE="0660" ÂÂ Â ~ ##传输到节点2~ scp 99-oracle-asmdevices.rules 到rac2 [root@roidb1 rules.d]# cat 99-oracle-asmdevices.rules KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB134477b8-eb4c906a", NAME="asm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB02fff4da-d0a0c3a3", NAME="asm-diskc", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VBdfa1c4b9-379f6810", NAME="asm-diskd", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB47ca97bf-4f2e68c0", NAME="asm-diske", OWNER="grid", GROUP="asmadmin", MODE="0660" KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VBf00cea14-af091329", NAME="asm-diskf", OWNER="grid", GROUP="asmadmin", MODE="0660" [root@roidb1 rules.d]# [root@roidb1 rules.d]# [root@roidb1 rules.d]# ##重启udev服务，加载配置文件 [root@roidb1 rules.d]# start_udev Starting udev: udevd[5477]: GOTO 'pulseaudio_check_usb' has no matching label in: '/lib/udev/rules.d/90-pulseaudio.rules' ##生产/dev/asm-diskf [ OK ] [root@roidb1 rules.d]# ls -l /dev/asm* brw-rw---- 1 grid asmadmin 8, 16 Jan 30 19:36 /dev/asm-diskb brw-rw---- 1 grid asmadmin 8, 32 Jan 30 19:36 /dev/asm-diskc brw-rw---- 1 grid asmadmin 8, 48 Jan 30 19:36 /dev/asm-diskd brw-rw---- 1 grid asmadmin 8, 64 Jan 30 19:36 /dev/asm-diske brw-rw---- 1 grid asmadmin 8, 80 Jan 30 19:36 /dev/asm-diskf /dev/asm: total 0 ##查看asm磁盘 SQL> col name for a40 SQL> set line 200 SQL> select name,path,state,HEADER_STATUS from v$asm_disk;
