10gRAC+RHEL5U2+ASM+iscsi(1)
一 实验规划：
| 主机名 | 软件 |
| sl410 | gentoo + sys-block/iscsitarget-0.4.17 |
| rac1 | VMware-Workstation-Full-7.0.0-203739.i386.bundle RedHat.Enterprise.Linux.5.Update.2-XiSO.iso 10201_clusterware_linux32.iso 10201_database_linux32.iso iscsi-initiator-utils-6.2.0.868-0.7.el5.i386.rpm oracleasm-2.6.18-92.el5-2.0.5-1.el5.i686.rpm oracleasmlib-2.0.4-1.el5.i386.rpm oracleasm-support-2.1.3-1.el5.i386.rpm |
| rac2 | VMware-Workstation-Full-7.0.0-203739.i386.bundle RedHat.Enterprise.Linux.5.Update.2-XiSO.iso 10201_clusterware_linux32.iso 10201_database_linux32.iso iscsi-initiator-utils-6.2.0.868-0.7.el5.i386.rpm oracleasm-2.6.18-92.el5-2.0.5-1.el5.i686.rpm oracleasmlib-2.0.4-1.el5.i386.rpm oracleasm-support-2.1.3-1.el5.i386.rpm |
| 主机名 | 设备 | IP 地址 | 子网掩码 | 默认网关地址 |
| rac1 | eth0 | 192.168.0.44 | 255.255.255.0 | 192.168.0.1 |
| eth1 | 10.0.0.44 | 255.0.0.0 | 10.0.0.1 | |
| rac2 | eth0 | 192.168.0.45 | 255.255.255.0 | 192.168.0.1 |
| eth1 | 10.0.0.45 | 255.0.0.0 | 10.0.0.1 | |
| sl410 | eth0:1 | 10.0.0.1 | 255.0.0.0 | - |
ASM管理
| 设备名 | 大小(M) | 描述 |
| /dev/sdb1 | 100(at least) | Ocr |
| /dev/sdb2 | 100 | Votingdisk |
| /dev/sdb3 | 5000 | ASM1 |
| /dev/sdb4 | 5000 | ASM2 |
二 存储准备
由于rac1与rac2运行在vmware-workstation平台,而vmware-workstation没有vmware-server的共享存储功能.因此在sl410主机用iscsitarget发布共享硬盘设备.
下面命令存储发布一块10GB共享设备。其余磁盘划分的任务就让rac1与rac2去完成吧：）
| sl410 oracle # dd if=/dev/zero f=/home/storage.volume count=200 bs=50M sl410 oracle # /etc/init.d/ietd start sl410 oracle # ietadm --op new --tid=1 --params Name=storage sl410 oracle # ietadm --op new --tid=1 --lun=1 --params Path=/data/storage.volume |
可以查看发布情况
| storage oracle # ietadm --op show --tid=1 Wthreads=8 Type=0 QueuedCommands=32 |
| SL410 ~ # cat /proc/net/iet/volume tid:1 name:storage lun:1 state:0 iotype:fileio iomode:wt path:/data/storage.volume |
| SL410 ~ # netstat -a |grep 3260 tcp 0 0 *:3260 *:* LISTEN tcp6 0 0 [::]:3260 [::]:* LISTEN |
三 rac1与rac2存储配置
1.rac1与rac2发现共享存储
| [root@rac1 ~]# /etc/init.d/iscsid start Turning off network shutdown. Starting iSCSI daemon: [ OK ] [root@rac1 ~]# iscsiadm --mode discovery --type sendtargets --portal 192.168.0.29 --login 192.168.0.29:3260,1 storage Logging in to [iface: default, target: storage, portal: 192.168.0.29,3260] Login to [iface: default, target: storage, portal: 192.168.0.29,3260]: successful [root@rac1 ~]# fdisk -l Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 2610 20860402+ 8e Linux LVM Disk /dev/sdb: 10.4 GB, 10485760000 bytes 64 heads, 32 sectors/track, 10000 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Disk /dev/sdb doesn't contain a valid partition table [root@rac1 ~]# |
| [root@rac2 ~]# /etc/init.d/iscsid start Turning off network shutdown. Starting iSCSI daemon: [ OK ] [root@rac2 ~]# iscsiadm --mode discovery --type sendtargets --portal 192.168.0.29 --login 192.168.0.29:3260,1 storage Logging in to [iface: default, target: storage, portal: 192.168.0.29,3260] Login to [iface: default, target: storage, portal: 192.168.0.29,3260]: successful [root@rac2 ~]# fdisk -l Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 2610 20860402+ 8e Linux LVM Disk /dev/sdb: 10.4 GB, 10485760000 bytes 64 heads, 32 sectors/track, 10000 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Disk /dev/sdb doesn't contain a valid partition table |
2 对共享存储分区
| [root@rac1 ~]# fdisk -l Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 2610 20860402+ 8e Linux LVM Disk /dev/sdb: 10.4 GB, 10485760000 bytes 64 heads, 32 sectors/track, 10000 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 500 511984 83 Linux /dev/sdb2 501 1000 512000 83 Linux /dev/sdb3 1001 5500 4608000 83 Linux /dev/sdb4 5501 10000 4608000 83 Linux |
3 映射sdb1 sdb2为raw
rac1配置
| [root@rac1 ~]# raw /dev/raw/raw1 /dev/sdb1 /dev/raw/raw1: bound to major 8, minor 17 [root@rac1 ~]# raw /dev/raw/raw2 /dev/sdb2 /dev/raw/raw2: bound to major 8, minor 18 |
rac2配置
| [root@rac2 ~]# raw /dev/raw/raw1 /dev/sdb1 /dev/raw/raw1: bound to major 8, minor 17 [root@rac2 ~]# raw /dev/raw/raw2 /dev/sdb2 /dev/raw/raw2: bound to major 8, minor 18 |
将raw命令写入rc.local以便系统重启后能自动映射:)
| [root@rac1 ~]# cat /etc/rc.local #!/bin/sh # # This script. will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style. init stuff. raw /dev/raw/raw1 /dev/sdb1 raw /dev/raw/raw2 /dev/sdb2 sleep 5 chown -R oracle:oinstall /dev/raw touch /var/lock/subsys/local [root@rac1 ~]# |
