Implement ASM on LVM

Environment: RHEL-5.8 ORACLE _ 10gr2

 

Bind a bare Device

[root@localhost ~]# fdisk -lDisk /dev/sda: 32.2 GB, 32212254720 bytes255 heads, 63 sectors/track, 3916 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes   Device Boot      Start         End      Blocks   Id  System/dev/sda1   *           1          13      104391   83  Linux/dev/sda2              14        1288    10241437+  83  Linux/dev/sda4            1289        3916    21109410    5  Extended/dev/sda5            1289        1301      104391   8e  Linux LVM/dev/sda6            1302        1314      104391   8e  Linux LVM/dev/sda7            1315        1327      104391   8e  Linux LVM/dev/sda8            1328        1340      104391   8e  Linux LVM/dev/sda9            1341        1353      104391   8e  Linux LVM/dev/sda10           1354        1366      104391   8e  Linux LVM/dev/sda11           1367        1379      104391   8e  Linux LVM/dev/sda12           1380        1392      104391   8e  Linux LVM

② In/etc/sysconfig/rawdevices, add:

/dev/raw/raw5    /dev/sda5/dev/raw/raw6    /dev/sda6/dev/raw/raw7    /dev/sda7/dev/raw/raw8    /dev/sda8/dev/raw/raw9    /dev/sda9/dev/raw/raw10   /dev/sda10/dev/raw/raw11   /dev/sda11/dev/raw/raw12   /dev/sda12

③ Under assign_raw at start of/etc/rc. d/init. d/rawdevices, add:

sleep 3chown -R oracle:oinstall /dev/raw/

④ Check bare Devices

[root@localhost init.d]# chkconfig rawdevices on[root@localhost init.d]# partprobe[root@localhost init.d]# service rawdevices restartAssigning devices:            /dev/raw/raw5  -->   /dev/sda5/dev/raw/raw5:  bound to major 8, minor 5           /dev/raw/raw6  -->   /dev/sda6/dev/raw/raw6:  bound to major 8, minor 6           /dev/raw/raw7  -->   /dev/sda7/dev/raw/raw7:  bound to major 8, minor 7           /dev/raw/raw8  -->   /dev/sda8/dev/raw/raw8:  bound to major 8, minor 8           /dev/raw/raw9  -->   /dev/sda9/dev/raw/raw9:  bound to major 8, minor 9           /dev/raw/raw10  -->   /dev/sda10/dev/raw/raw10: bound to major 8, minor 10           /dev/raw/raw11  -->   /dev/sda11/dev/raw/raw11: bound to major 8, minor 11           /dev/raw/raw12  -->   /dev/sda12/dev/raw/raw12: bound to major 8, minor 12done[root@localhost init.d]# raw -qa/dev/raw/raw5:  bound to major 8, minor 5/dev/raw/raw6:  bound to major 8, minor 6/dev/raw/raw7:  bound to major 8, minor 7/dev/raw/raw8:  bound to major 8, minor 8/dev/raw/raw9:  bound to major 8, minor 9/dev/raw/raw10: bound to major 8, minor 10/dev/raw/raw11: bound to major 8, minor 11/dev/raw/raw12: bound to major 8, minor 12

⑤ Add permissions

[Root @ localhost init. d] # cd/dev/raw/[root @ localhost raw] # ls-L total 0crw ------- 1 Oracle oinstall 162, 10 10-31 23:35 raw10crw ------- 1 Oracle oinstall 162, 11 10-31 raw11crw ------- 1 Oracle oinstall 162, 12 10-31 raw12crw ------- 1 Oracle oinstall 162, 5 10-31 raw5crw ------- 1 Oracle oinstall 162, 6 10-31 raw6crw ------- 1 Oracle oinstall 162, 7 10-31 raw7crw ------- 1 Oracle oinstall 162, 8 10-31 raw8crw ------- 1 Oracle oinstall 162, 9 10-31 raw9 [root @ localhost raw] # chmod 660 * [root @ localhost raw] # ls-L total 0crw-rw ---- 1 Oracle oinstall 162, 10 10-31 raw10crw-rw ---- 1 Oracle oinstall 162, 11 10-31 raw11crw-rw ---- 1 Oracle oinstall 162, 12 10-31 raw12crw-rw ---- 1 Oracle oinstall 162, 5 10-31 raw5crw-rw ---- 1 Oracle oinstall 162, 6 10-31 raw6crw-rw ---- 1 Oracle oinstall 162, 7 10-31 raw7crw-rw ---- 1 Oracle oinstall 162, 8 10-31 raw8crw-rw ---- 1 Oracle oinstall 162, 9 10-31 raw9

⑥ Start the CSS Service

[root@localhost ~]# cd /u01/app/oracle/product/10.2.0/db_1/bin[root@localhost bin]# ./localconfig add/etc/oracle does not exist. Creating it now.Successfully accumulated necessary OCR keys.Creating OCR keys for user 'root', privgrp 'root'..Operation successful.Configuration for local CSS has been initializedAdding to inittab Startup will be queued to init within 90 seconds.Checking the status of new Oracle init process...Expecting the CRS daemons to be up within 600 seconds.CSS is active on these nodes.        localhostCSS is active on all nodes.Oracle CSS service is installed and running under init(1M)

7. Check CSS

[root@localhost ~]# strings /etc/inittab......h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1 </dev/null[root@localhost ~]# ps aux | grep cssroot     18650  0.0  0.1   2952  1160 ?        S<s  23:43   0:00 /bin/su -l oracle -c sh -c 'cd /u01/app/oracle/product/10.2.0/db_1/log/localhost/cssd;  ulimit -c unlimited; exec /u01/app/oracle/product/10.2.0/db_1/bin/ocssd 'oracle   18749  0.0  1.3 149296  8660 ?

Mongodbca Process

 

⑨ Start the ASM instance

[oracle@localhost ~]$ export ORACLE_SID=+ASM[oracle@localhost ~]$ sqlplus /nologSQL*Plus: Release 10.2.0.1.0 - Production on Thu Nov 1 00:19:25 2012Copyright (c) 1982, 2005, Oracle.

Summary:

Although it is not recommended to deploy ASM on LVM on the official website, the environment where I am located is tossing around on LVM ...... Of course, there are still many issues to be aware of during the establishment of ASM. I will make up for them later, and I will only give a brief introduction here.
