Shared Storage Check

Hi all,
We are planning to add a node to our existing RAC deployment (Database: 10gr2 and Sun Solaris 5.9 OS). Currently the shared storage is IBM SAN.
When i run shared storage check using cluvfy, it fails to detect any shared storage. Given that i can ignore this error message (since cluvfy doesn't work wth SAN i beleive), how can i check whether the storage is shared or not?
Note
When i see partition table from both servers, it looks same (for the SAN drive, of course) but the name/label of the storages are different (For example: In existing node it show c6t0d0 but in the new node, which is to be added, it shows something different. Is it ok?).
regards,
Muhammad Riaz

Never mind. I found solution from http://www.idevelopment.info.
(1) Create following directory structure on second node (same as first node) with the same permissions on existins node:
/asmdisks
- crs
-disk1
-disk2
- vote
(2) use ls -lL /dev/rdsk/<Disk> to find out major and minor ids of shared disk and attach those ids to relveant direcotries above using mknod command:
# ls -lL /dev/rdsk/c4t0d0*

Hello,
It seems that your storage is not accessible from both the nodes. If you want you can follow these steps to configure 10g RAC on VMware.
Steps to configure Two Node 10 RAC on RHEL-4
Remark-1: H/W requirement for RAC
a) 4 Machines
1. Node1
2. Node2
3. storage
4. Grid Control
b) 2 switchs
c) 6 straight cables
Remark-2: S/W requirement for RAC
a) 10g cluserware
b) 10g database
Both must have the same version like (10.2.0.1.0)
Remark-3: RPMs requirement for RAC
a) all 10g rpms (Better to use RHEL-4 and choose everything option to install all the rpms)
b) 4 new rpms are required for installations
1. compat-gcc-7.3-2.96.128.i386.rpm
2. compat-gcc-c++-7.3-2.96.128.i386.rpm
3. compat-libstdc++-7.3-2.96.128.i386.rpm

3. storage configuration
PART-A Open-filer Set-up
Install openfiler on a machine (Leave 60GB free space on the hdd)
a) Login to root user
b) Start iSCSI target service
# service iscsi-target start
# chkconfig –level 345 iscsi-target on
PART –B Configuring Storage on openfiler
a) From any client machine open the browser and access openfiler console (446 ports).
https://192.9.201.182:446/
b) Open system tab and update the local N/W configuration for both nodes with netmask (255.255.255.255).
c) From the Volume tab click "create a new physical volume group".
d) From "block Device managemrnt" click on "(/dev/sda)" option under 'edit disk' option.
e) Under "Create a partition in /dev/sda" section create physical Volume with full size and then click on 'CREATE'.
f) Then go to the "Volume Section" on the right hand side tab and then click on "Volume groups"
g) Then under the "Create a new Volume Group" specify the name of the volume group (ex- racvgrp) and click on the check box and then click on "Add Volume Group".
h) Then go to the "Volume Section" on the right hand side tab and then click on "Add Volumes" and then specify the Volume name (ex- racvol1) and use all space and specify the "Filesytem/Volume type" as ISCSI and then click on CREATE.
i) Then go to the "Volume Section" on the right hand side tab and then click on "iSCSI Targets" and then click on ADD button to add your Target IQN.
j) then goto the 'LUN Mapping" and click on "MAP".
k) then goto the "Network ACL" and allow both node from there and click on UPDATE.
Note:- To create multiple volumes with openfiler we need to use Multipathing that is quite complex that’s why here we are going for a single volume. Edit the property of each volume and change access to allow.
f) install iscsi-initiator rpm on both nodes to acces iscsi disk
#rpm -ivh iscsi-initiator-utils-----------
g) Make entry in iscsi.conf file about openfiler on both nodes.
#vim /etc/iscsi.conf (in RHEL-4)
and in this file you will get a line "#DiscoveryAddress=192.168.1.2" remove comment and specify your storage ip address here.
OR
#vim /etc/iscsi/iscsi.conf (in RHEL-5)
and in this file you will get a line "#ins.address = 192.168.1.2" remove comment and specify your storage ip address here.
g) #service iscsi restart (on both nodes)
h) From both Nodes fire this command to access volume of openfiler-
# iscsiadm -m discovery -t sendtargets -p 192.2.201.182
i) #service iscsi restart (on both nodes)
j) #chkconfig –level 345 iscsi on (on both nodes)
k) make the partition 3 primary and 1 extended and within extended make 11 logical partition
A. Prepare partitions
1. #fdisk /dev/sdb
:e (extended)
Part No. 1
First Cylinder:
Last Cylinder:
:p
:n
:l
First Cylinder:
Last Cylinder: +1024M
2. Note the /dev/sdb* names.
3. #partprobe
4. Login as root user on node2 and run partprobe
B. On node1 login as root user and create following raw devices
# raw /dev/raw/raw5 /dev/sdb5
#raw /dev/raw/taw6 /dev/sdb6
# raw /dev/raw/raw12 /dev/sdb12
Run ls –l /dev/sdb* and ls –l /dev/raw/raw* to confirm the above
-Repeat the same thing on node2
C. On node1 as root user
# vi .etc/sysconfig/rawdevices

done
E. Repeat the same thing on node2 also
F. To make these partitions accessible to oracle user fire these commands from both Nodes.
# chown –R oracle:oinstall /dev/raw/raw*
# chmod –R 755 /dev/raw/raw*
F. To make these partitions accessible after restart make these entry on both nodes
# vi /etc/rc.local
Chown –R oracle:oinstall /dev/raw/raw*
Chmod –R 755 /dev/raw/raw*
4. SSH configuration (User quivalence)
On node1:- $ssh-keygen –t rsa
$ssh-keygen –t dsa
On node2:- $ssh-keygen –t rsa
$ssh-keygen –t dsa
On node1:- $cd .ssh
$cat *.pub>>node1
On node2:- $cd .ssh
$cat *.pub>>node2
On node1:- $scp node1 node2:/home/oracle/.ssh
On node2:- $scp node2 node2:/home/oracle/.ssh
On node1:- $cat node*>>authowized_keys
On node2:- $cat node*>>authowized_keys
Now test the ssh configuration from both nodes
$ vim a.sh
ssh node1 hostname
ssh node2 hostname
ssh node1-priv hostname
ssh node2-priv hostname
$ chmod +x a.sh
$./a.sh
first time you'll have to give the password then it never ask for password
5. To run cluster verifier
On node1 :-$cd /…/stage…/cluster…/cluvfy
$./runcluvfy stage –pre crsinst –n node1,node2
First time it will ask for four New RPMs but remember install these rpms by double clicking because of dependancy. So better to install these rpms in this order (rpm-3, rpm-4, rpm-1, rpm-2)
1. compat-gcc-7.3-2.96.128.i386.rpm
2. compat-gcc-c++-7.3-2.96.128.i386.rpm
3. compat-libstdc++-7.3-2.96.128.i386.rpm
4. compat-libstdc++-devel-7.3-2.96.128.i386.rpm
And again run cluvfy and check that "It should given a clean cheat" then start clusterware installation.

Please help me out. Thank you!!

I just ran into this myself while building an enterprise system on Win Server 2003. The answers here did not sit well with me and I needed to be sure of the shared storage prior to proceeding further. Researching Metalink did not uncover any relevant information either. I then opened an SR with Oracle and I did get back a satisfactory response which allowed me to verify my shared storage. The entire text of their solution can be found at http://www.webofwood.com/rac/oracle-response-to-shared-storage-check-failed-on-nodes/. Basically, it is a method of using another utility to identify the storage device names used by Windows and then writing and reading to them from each node to verify each node 'sees' what is written by the other node(s). If this check is successful, you can then proceed.

Hi,
CLUFVY COMP SSA checks if the used storage/location is shared.
If you do "cluvfy comp ssa -t software" cluvfy checks if your software home is shared.
It tells you it is not. Hence the checks fails (which is correct, because you said DB Home is not shared).
So where is the problem?
CLUVFY COMP SSA only makes sense to check the sharedness. If it is not shared, then there is no sense in testing for it.

When installing clusterware, shared storage trouble

I was trying to install clusterware. When I typed location of OCR, I got error below:
Oracle Cluster Registry (OCR) is not shared across all the nodes in the cluster
Then, I found I can not mount ocfs2 on both nodes at the same time. But I can mount it on any one of nodes if it is umounted on the other one.
Can you anyone give me a hand?
Environment is as following:
- OS: Oracle Linux 5 (update 4)
- Openfiler 3 + ocfs2
- Oracle 10gR2

is there any thing do i have to do to make it work ??Check to see if the physical disk appears under the default volume group for your san. If not, refresh the san and wait until it does. Also, make sure you have an admin server configured for that san and that your Oracle VM servers are in the default access group.

BWA OS Upgrade Error Shared Storage

We have recently upgraded our IBM BWA to SUSE Linux 11.1, upgraded the GPFS 3.4.0-7 and recompiled RDAC. Everything seemed to work fine, the queries execute, but when I run the checkBIA, I get these warning/error messages:

Anyone seen this before, or have any idea what may be the cause? Thank you

Hello Karl,
first, BWA is not supported for all SUSE versions. Please check http://service.sap.com/pam > "BW Accelerator 7.20". It's certainly not supported for BWA 7.0.
Secondly, you should not upgrade the OS unless specifically instructed to do so by SAP Support or if security patches are required. Especially moving from SUSE 9 or 10 to 11 is not something that is recommended.
Finally, because of #1 please contact IBM to make sure you have a supported OS version for your specific BWA hardware. IBM also needs to make sure that your hardware fulfills the minimum specifications for network and storage throughput (which is check by the script).
Thanks,

Shared storage is a hardware device, which cant be created by you. Ofcourse you can use that shared device to configure ASM.

can You help me where I doing mistake
thank You Brano

Please find the answer in the below link

Server Pool WITHOUT shared storage

The documentation defines Server Pool as:
+Logically an autonomous region that contains one or more physical Oracle VM Servers.+
Therefore, should it possible to add multiple servers (physically separate VM servers) to the same Server Pool even though they are NOT using shared storage? When I tried to add the second VM Server to the Server Pool I received the following error:
During adding servers ([vmoracle2]) to server pool (VM_Server_Pool), Cluster setup failed:
(OVM-1011 OVM Manager communication with vmoracle1 for operation HA Setup for Oracle VM
Agent 2.2.0 failed: <Exception: SR '/dev/sda3' not supported: type 'ocfs2.local' not in
['nfs', 'ocfs2.cluster']> )Thanks.

Nothing is as easy as it seems when it comes to Oracle VM.
When trying to create a new Server Pool to accommodate my second VM Server, I received the following error:

Runcluvy on shared storage

Hey, I just might forget anything.
I am going to install a rac cluster on SLES11 SP1.
I am using multipathing where shared storage are provided by two SAN´s.
I see all LUNs and did a raw device mapping via disk by-id ( all LUNs hava a partion on it)
I am able to write with dd on the raw devices from both rac nodes at the same time.
I set the permissions to the raw devices
Installed cluvy.rpm on both nodes.
When I start cluvy it passes the first checks successful.
./runcluvfy.sh stage -post hwos -n raca,racb -verbose
But when its starts checking the shared storages - it fails.
But prereq needs to be configured for a successful check of the storage devices ?
Chris
cluvy comes out of the installation package from 10.2.0.1

cluvy comes out of the installation package from 10.2.0.1do you want to do pre-check or post-check?
if you would like to do pre-check, check with
./runcluvfy.sh stage -pre crsinst -n raca,racb -verbose
HTH,
Refer installation guide for reference.
Good Luck.

Backup Exec 9.2 SSO (shared storage option) SCSI LTO

Greetings, all...
I have a 2-node cluster setup at a particular client. Backup Exec is licensed for SSO, and unfortunately, while I have the HP Ultrium 960 in the middle of a shared SCSI bus between the two servers, because it's not on the SAN, Backup Exec apparently refuses to recognize it as a valid shared storage device.
I was wondering if anyone has been able to get around this in Backup Exec, as the drive is indeed shared (can be seen) by both servers. When using a clustered setup, but without SSO, it is difficult to keep the media management in sync, as each node is given its own subdirectory instead of sharing the media management db.
TIA

Acessing shared storage

For some reason I just cannot access the shared storage device on my home network. The device appears as a media device, but not as a computer as it normally does. I have tried every kind of troubleshooting, but nothing seems to work.

Hi,
If the issue did not occur before, you may try to use the system restore, return to the point which did not appear the problem.
Please try the following:
1. Check the permission settings of the network storage device: Add Everyone to Sharing tab and Security tab
2. Adjust "File sharing connections” encryption setting:
a. Go to “Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings”.
b. Adjust the File sharing connections setting and check if the computer can access the network storage device.
3. Please temporarily disable Windows Firewall and security software.
4. Try to manually use UNC (\\server\share) and IP (\\ip.add.res.s\share) to access the device for a test.
Please also use Device Manager to verify that your network adapter is working correctly and reinstall the drivers.
If the shared folder still can’t be accessed, please re-create the connection and check the result again.
Hope it helps.

Blair Deng

Find shared storage in clustered nodes

Hi,
How to check shared storage in clustered nodes
OS – Solaris
Regards,
M@rk....

I've just discovered that one of the SCSI cards was faulty which explains why I couldn't see all the disks from one of the nodes.
