[root@rac20 ~]#




Execute following as root, it will configure the iscsi to pick server san1.rac.meditate.com at each start-up:

service iscsi start
iscsiadm -m discovery -t sendtargets -p san1.rac.meditate.com

Output is as:

[root@rac20 ~]# service iscsi start

[root@rac20 ~]# iscsiadm -m discovery -t sendtargets -p san1.rac.meditate.com

Starting iscsid:                                           [  OK  ]

10.10.1.116:3260,1 iqm.mgmt.volumes-san

[root@rac20 ~]#

Later if you ever want to add more servers for SAN to the configuration, you can use the same command given above. But if you want to remove some ip/name from the configuration use something like the one given below:

To disable running service:
iscsiadm --m node --portal 10.10.1.156:3260 -u

To delete the old ip:
iscsiadm -m node -o delete --portal 10.10.1.156:3260

Note - sdb to sdx are the iscsi disks and if you don't see them reboot the machine and try discovery again and you should be able to see these luns.

Execute following as root so that iscsi service starts on every reboot.

chkconfig --level 345 iscsi on

Output is as follows :

[root@rac20 ~]# chkconfig --level 345 iscsi on

[root@rac20 ~]#

Now create the following directories and chnage their ownership.

mkdir /u01 /u02 /software

chown oracle:oinstall /u01 /u02 /software

Output is as:

[root@rac20 ~]# mkdir /u01 /u02 /software

[root@rac20 ~]# chown oracle:oinstall /u01 /u02 /software

[root@rac20 ~]#

Now do the following change :

create file "/etc/resolv.conf_shld_be" and the contents should be:

[root@rac10 ~]# cat /etc/resolv.conf_shld_be

# Generated by NetworkManager

nameserver 192.168.1.117

search rac.meditate.com

[root@rac10 ~]#

edit file "/etc/rc.d/rc.local" and the following in the end on this file:

#Command to fix the permissions of the luns

service iptables stop

chown oracle:oinstall /dev/sd[b-x]

# Command to fix scan ip

rm -rf /etc/resolv.conf

cp /etc/resolv.conf_shld_be /etc/resolv.conf

Cat on this file should look like following:

[root@rac20 ~]# cat  /etc/rc.d/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.

touch /var/lock/subsys/local

#Command to fix the permissions of the luns

service iptables stop

chown oracle:oinstall /dev/sd[b-x]

# Command to fix scan ip

rm -rf /etc/resolv.conf

cp /etc/resolv.conf_shld_be /etc/resolv.conf

[root@rac20 ~]#

Now bounce the machine using command "reboot" as user root.

Now as root execute "ls -l /dev/sd*" and you should see the following luns:

[root@rac20 ~]# ls -l /dev/sd*

Lets create ASM disks as:

Create a new file:

"/etc/scsi_id.config"

and here should be its contents:

options=-g

So cat on the file looks like:

[root@rac20 ~]# cat /etc/scsi_id.config

options=-g

[root@rac20 ~]#

Now execute hte following commands as root and geet their names.

[root@rac20 ~]#

In the same way fomat all these disks.

/dev/sd[d-x]

Options are:

n,p,1,enter,enter,w

Once done execute following as root:

/sbin/udevadm control --reload-rules

/sbin/start_udev

and then execute the following command as root and you should see all the ASM disks:

ls -al /dev/asm*

The disks should now be visible and have the correct ownership using the following command. If they are not visible, your UDEV configuration is incorrect and must be fixed before you proceed.

[root@rac20 ~]# ls -al /dev/asm*

[root@rac20 ~]#

The shared disks are now configured for the grid infrastructure.

Now reboot the machine and check the disks look good by executing the following command:

ls -al /dev/asm*

Now shutdown the machine using command "shutdown -h now".

Now on console edit the machine configuration and allocate 1536 MB to this machine instead of 2GB as for RAC install I was able to install grid infrastructure and rac software with only 1.5GB

and take its backup copy and name it "rac20_ready"

Then create 3 more copies as and name then "rac21", "rac22" and "rac23"

On all the machines in thier configuration file like we did earlier update entry 

Change following:

scsi0:0.fileName = "C:\VM\rac_12c\rac20\bbm.vmdk"

to

scsi0:0.fileName = "C:\VM\rac_12c\rac21\bbm.vmdk"

to

scsi0:0.fileName = "C:\VM\rac_12c\rac22\bbm.vmdk"

to

scsi0:0.fileName = "C:\VM\rac_12c\rac23\bbm.vmdk"

respectively

rm -f /etc/udev/rules.d/70-persistent-net.rules

vi /etc/sysconfig/network

and update the hostname from rac20.rac.meditate.com to rac21.rac.meditate.com, rac22.rac.meditate.com, rac23.rac.meditate.com respectively 

vi /etc/sysconfig/network-scripts/ifcfg-eth0

update ip here in all the machines

vi /etc/sysconfig/network-scripts/ifcfg-eth1

update ip here in all the machines

vi /etc/sysconfig/network-scripts/ifcfg-eth2

update ip here in all the machines

vi /etc/sysconfig/network-scripts/ifcfg-eth3

update ip here in all the machines

vi /etc/resolv.conf_shld_be

update ip to hostmachine's ip respectively e.g. 192.168.1.117/118/119/120 on all the machines

Now copy the oracle software using WinSCP as user oracle to rac20 machine under /software

Now login to rac20 as oracle and 

cd to where you copied the software and unzip it. 

 cd /software/12c_database_and_grid_infrastructure

 unzip V38500-01_1of2.zip

 unzip V38500-01_2of2.zip

 unzip V38501-01_1of2.zip

 unzip V38501-01_2of2.zip

 after this ls -lart looks like :

 [oracle@rac20 12c_database_and_grid_infrastructure]$ ls -lart

 total 4325924

 drwxr-xr-x 7 oracle oinstall       4096 Jun 10 05:14 database

 drwxr-xr-x 7 oracle oinstall       4096 Jun 10 05:15 grid

 -rw-r--r-- 1 oracle oinstall  201673595 Jun 25 22:43 V38501-01_2of2.zip

 -rw-r--r-- 1 oracle oinstall 1116527103 Jun 25 23:17 V38500-01_2of2.zip

 -rw-r--r-- 1 oracle oinstall 1361028723 Jun 25 23:22 V38500-01_1of2.zip

 -rw-r--r-- 1 oracle oinstall 1750478910 Jun 25 23:35 V38501-01_1of2.zip

 drwxr-xr-x 3 oracle oinstall       4096 Jul 18 23:48 ..

 drwxr-xr-x 4 oracle oinstall       4096 Jul 19 00:00 .

 [oracle@rac20 12c_database_and_grid_infrastructure]$

Now to save space remove the zip files by executing:

rm V38501-01_2of2.zip V38500-01_2of2.zip V38500-01_1of2.zip V38501-01_1of2.zip

Finally it looks like following:

[oracle@rac20 12c_database_and_grid_infrastructure]$ ls -lart

total 16

drwxr-xr-x 7 oracle oinstall 4096 Jun 10 05:14 database

drwxr-xr-x 7 oracle oinstall 4096 Jun 10 05:15 grid

drwxr-xr-x 3 oracle oinstall 4096 Jul 18 23:48 ..

drwxr-xr-x 4 oracle oinstall 4096 Jul 19 00:05 .

[oracle@rac20 12c_database_and_grid_infrastructure]$

Now "shutdown -h now" all the machines if you want and have space take backup of "rac20","rac21","rac22","rac23"

Let my feet walk on Your Path, and let my eyes behold the Blessed Vision of Your Darshan. With my ears, I will listen to Your Sermon, if the Guru becomes merciful to me.

[root@san1 ~]#

Bounce the VM again with "reboot"

Verify target is ready and the LUNs are present:

tgtadm --lld iscsi --op show --mode target

You should see something like the following:

[root@san1 ~]# tgtadm --lld iscsi --op show --mode target

Target 1: iqm.mgmt.volumes-san

Now shutdown the machine using command “shutdown –h now”

On console of this machine do the following:

Click “Edit virtual machine settings”  and on the following screen enter 256MB in front of “Memory for this virtual machine” and click ok.

and take its backup. Copy folder “san1” inder directory “C:\VM\rac_12c” in the same directory and I will name the backup folder as “san1_ready”, it is required only if you mess-up something during install and want to restore san1 machine.

Everyone calls God his own, O Siblings of Destiny, but the

all-knowing Lord is known only through the Guru. Those who are pierced by His Love are saved, O Siblings of Destiny; they bear the Insignia of the True Word of the Shabad. |
