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,

Qmaster error: shared storage client timed out while subscribing to...

Here's my Qmaster setup:
computer 1: CONTROLLER, no nodes
- 8TB RAID hooked up via Fiber
- connected to the GigE network switch via a 6-port bond
- cluster storage set to a path on the RAID
computers 2, 3, 4, 5: RENDER NODES
- each computer has a 2-port bonded connection with the GigE switch
computer 6: Client, with FCS2 installed.
- connected with a single GigE link
I have set up this cluster primarily for command-line renders, and it works great. I submit command-line renders from the client computer, which get distributed and executed on each node. The command line renders specify a source file on the RAID, and a destination path on the RAID. Everything works great.
I run into trouble when trying to use Compressor with this same setup. The files are on the RAID, and all my computers have an NFS automount that puts it in the /Volumes folder on each computer.
I set up my Compressor job and submit it to the cluster. It submits sucessfully, and distributes the work. After a few seconds, each node gives me a timeout error:
"Shared storage client timed out while subscribing to [computer1.local/path to cluster storage]"
Is this a bandwidth issue? Command line renders work fine, I can render 16 simultaneous Quicktimes to the RAID over NFS. I don't see much network activity on any of the computers when it's trying to start the Compressor render, it's as if it's not even trying to connect.
If I submit the SAME compressor job to a cluster with nodes ONLY on the controller computer, it renders fine. Clearly the networked nodes are having trouble connecting to the share for some reason.
Does anybody have any ideas? I have tried almost everything to get this to work. Hooking up each node locally to the RAID is NOT an option unfortunately.

WELL I DO NOW!
Thanks. it's taken 6th months and several paid 'professionals' and then you come in here...swinging your minimalist genius. one line. one single line. and its done.

Shared storage client timed out error

Hello everybody, please help
I have been at this now for about 2 days and still can't find out the source of my issue using FCP to render a project through compressor to multiple macs using Qmaster.
What is happening is that I start the render and it gets sent to the second computer, I can see the prosessor ramping up then after (+-) 30 seconds I get the error bellow, and the render fails.
Here is my set up:
MacBook1 as the cluster controller
Macbook2 as the service node
connected via a gigabyte switch using an ethernet cable
The error I keep getting is this ("Macintosh-7" is the name of MacBook1, "chikako-komatsus-computer" is the name of MacBook2):
3x HOST [chikako-komatsus-computer.local] Shared storage client timed out while subscribing to "nfs://Macintosh-7.local/Volumes/portable/Cluster_scratch/4AD40699-B5BD6A1A/sha red"
The volume mentioned above in the error is a shared Fire wire drive connected to the MacBook1. It is have full read and write privileges to everyone. This drive is where the project file and all the source video are located. MacBook1 via the Qmaster system preferences is pointing to a folder "Cluster_scratch" on this drive.
I have been mounting this drive from macBook2 using the connect to sever option in the finder under Go menu. This method seems to only enable me to connect to this drive using AFP, is this my problem?
I have "allowed all incoming traffic" of the fire wall on the MacBook1
What is funny (not really) is that i can Compress a previously compiled video with the cluster If I don't go thou Final Cut Pro!
Any help with this would be greatly appreciated.
Thanks

I also administer a managed cluster with 6 machines, and have been using it successfully for almost a year now. But the only encoding that is submitted is directly through Compressor, never via FCP.
With QMaster, it sees a Quickcluster and a managed cluster the same way. While they are set up differently, the principle is the same, QMaster only sees services.
Exporting out of FCP to any cluster has always been slow. If you want to harness the power of distributed encoding, you could export a Quicktime reference file and take that into Compressor to be submitted to the cluster for encoding.

Upgrade 3.1- 7.0: internal error Workbook storage fault (read/open)

Dear all,
after upgrading an 3.1 (SP12) BW-system to BI 7.0 (SP15) the following error occures when we want to open existing BEx workbooks (in the BEx Analyzer 3.x):
<b><internal error> Workbook storage fault (read/open)</b>
<b>We have found out, that this refers only to those BW workbooks being created in BW 2.x and not modified ever since. Thus this actually seems to be an 2.x->7.0 issue.</b>
Scope of our projekt it not the use of any new BI function, we are just upgrading the system.
Unfortunately some (but not all) workbooks do not run any more now. Checking existing SAPnotes has not helped yet unfortunately.
I saw very similar problems on this forum, if there is a solution, please provide it to us urgently.
THANKS for helping
Frank

Hello Venkat,
thanks for helping. Since I work with SAP_ALL authorization, I do not think this issue is related to missing auth. objects. The error message desribed above is withoutan number-ID, that´s why it is different than those described in the mentioned notes.
It definitely is related with the upgrade, as I can open those "corrupt" workbooks originating from BW 2.x in the productive system (still on BW3.1).
Any more suggestions?? Who remembers the 2.x - 3.x upgrade of BEx workbooks?
Thanks, Frank

Access iphoto 08 file on shared storage device from multiple machines

I recently installed ilife 08 on both an imac and macbook. Previously (iphoto 06), both devices accessed the iphoto library on a shared storage device without any problems. After the upgrade, my imac is able to view thelibrary but my macbook (the second machine to be upgraded) no longer has access. 'Sharing' is too slow over the wireless network and doesn't represent a reasonable option.
Is anyone else experiencing this issue? Any suggestions.

Actually, neither repairing permissions or changing them with Get Info worked for me. What did work for me was deleting the empty iPhoto Library in the user folder who couldn't access the shared library, and put an alias of the shared library in that user's Pictures folder. Everything then worked as it did prior to upgrading. Thanks.

Problem of using OCFS2 as shared storage to install RAC 10g on VMware

Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition

Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!

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*

WRT610N Shared Storage

I recently purchased a WRT610N and have been having some problems setting up the USB shared storage feature. I have a 1.5 Terabyte Seagate drive that I have created two partiions on (I had read elsewhere in the forums that the WRT610N only handled partitions/dirves up to 1 TB). Both partitions are NTFS with the first one being 976,561 GB and the second one being 420,700 GB. Both drives show up in the "Disk" section of the admin console and I can create/define a share for the larger of the two partitions without any problems.
The first of my problems comes when I try to create/define a share for the smaller partition. I can create a share but the admin console does not save the access privleges that I assign to it. Despite setting them up in the admin console they don't show up when I go back and look (in both the detail and summary views) the Access rights show as blank. I do not have this issue with the larger partition where I can add and later view groups in the Access section.
The second problem comes when I try to attach to the larger share from a network client. I can look at the shares if I use ..........Start - Run - and Type \\192.168.1.1. If I enter in my admin User ID and password, I can see the new share on the WRT610N. When I try to double click on it, I am then pompted again for a Username & Password, When I try to re-enter the admin user ID and password, the logon comes right back to me with "WRT610n\admin" populated in the User ID field. From there it won't accept the admin password. There are no error messages.
Help with either problem would be appreciated.

When you select your Storage partition and open it, and if it ask you for the Username and Password, thats the username and password is of your storage drive, Might be you must have set some password for your storage drivers.
Login to your Routers GUI. and click on the Storage Tab and Below you will find the Sub tab "Administration" click on it, if you wish you can Modify the "admin" rights, Like change the password or else you can Create your Own User and password. So whenever you login to your Storage Partition, and it ask for the username and password then you can input that username and password and click OK. This way you will be able to access your Storage Driver.

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:

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:

Sync manager part fail: "Error: Insufficient Storage Space&qu

I'm using sync manager to transfer my collection of 3502 songs from my Zen Xtra to my PC before I upgrade to a 60GB Vision M.
It completes the sync but with 92 songs moved and a message that it is "complete with errors". The remaining songs each have the message "Error: Insufficient Storage Space"
The peculiar thing, my computer has 240GBs free!
Please can someone advise how to fix this and backup my songs? - Thank you.

You're not the only one with problems synching with?an Xtra. It appears that creative introduced a bug in their newer software that causes the transfer to fail regardless of how much space you have. Try installing the old software that came with the Xtra to copy it off. Creative sure has stellar support for their products, eh?Next time I'll go with another vendor. This is simply shoddy service on their part.

2. network Configuration
#vim /etc/host
192.9.201.183 node1.oracle.com node1
192.9.201.187 node2.oracle.com node2

2. Prepare Both the nodes for installation
a. Set Kernel Parameters (/etc/sysctl.conf)
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
b. Configure /etc/security/limits.conf file
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
c. Configure /etc/pam.d/login file
session required /lib/security/pam_limits.so
d. Create user and groups on both nodes
# groupadd oinstall
# groupadd dba
# groupadd oper
# useradd -g oinstall -G dba oracle
# passwd oracle
e. Create required directories and set the ownership and permission.
# mkdir –p /u01/crs1020
# mkdir –p /u01/app/oracle/product/10.2.0/asm
# mkdir –p /u01/app/oracle/product/10.2.0/db_1
# chown –R oracle:oinstall /u01/
# chmod –R 755 /u01/
f. Set the environment variables
$ vi .bash_profile
ORACLE_BASE=/u01/app/oracle/; export ORACLE_BASE
ORA_CRS_HOME=/u01/crs1020; export ORA_CRS_HOME
#LD_ASSUME_KERNEL=2.4.19; export LD_ASSUME_KERNEL
#LANG=”en_US”; export LANG
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
/dev/raw/raw5 /dev/sdb5
/dev/raw/raw6 /dev/sdb6
/dev/raw/raw7 /dev/sdb7
/dev/raw/raw8 /dev/sdb8
/dev/raw/raw9 /dev/sdb9
/dev/raw/raw10 /dev/sdb10
/dev/raw/raw11 /dev/sdb11
/dev/raw/raw12 /dev/sdb12
/dev/raw/raw13 /dev/sdb13
/dev/raw/raw14 /dev/sdb14
/dev/raw/raw15 /dev/sdb15
D. Restart the raw service (# service rawdevices restart)
#service rawdevices restart
Assigning devices:
/dev/raw/raw5 --> /dev/sdb5
/dev/raw/raw5: bound to major 8, minor 21
/dev/raw/raw6 --> /dev/sdb6
/dev/raw/raw6: bound to major 8, minor 22
/dev/raw/raw7 --> /dev/sdb7
/dev/raw/raw7: bound to major 8, minor 23
/dev/raw/raw8 --> /dev/sdb8
/dev/raw/raw8: bound to major 8, minor 24
/dev/raw/raw9 --> /dev/sdb9
/dev/raw/raw9: bound to major 8, minor 25
/dev/raw/raw10 --> /dev/sdb10
/dev/raw/raw10: bound to major 8, minor 26
/dev/raw/raw11 --> /dev/sdb11
/dev/raw/raw11: bound to major 8, minor 27
/dev/raw/raw12 --> /dev/sdb12
/dev/raw/raw12: bound to major 8, minor 28
/dev/raw/raw13 --> /dev/sdb13
/dev/raw/raw13: bound to major 8, minor 29
/dev/raw/raw14 --> /dev/sdb14
/dev/raw/raw14: bound to major 8, minor 30
/dev/raw/raw15 --> /dev/sdb15
/dev/raw/raw15: bound to major 8, minor 31
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.
