Hi,
Check out the following link.
It provides the Dir structure in Win as well as in UNIX.
http://help.sap.com/saphelp_nw2004s/helpdata/en/a4/5964df13e8f14a9f1151bbf65304fe/content.htm.
Else you can refer to SAP Weeks material in which it will be explained very clearly.

@shl1024 ,
Hello and thank you for posting back with the screen shot.
Now if you can boot into your system and get to the desktop. Back up all your files you do not want to loose.
Once this is done. You will want to enter the system BIOS. You should be able to access the BIOS by tapping the F10 key as soon as you see the HP welcome screen. Once you are in the BIOS you will want to run a hard drive test.
Testing a Hard Disk from the BIOS
You will want to do this to make sure the hard drive is still in good shape. If it comes up with a bunch of issues in this test. Replace.
If not run other hard drive tests.
HP Notebook PCs - Testing a Hard Disk using the Built in Self Test
Now if this finds issues then if you have everything backed up you may be able to run the Windows system recovery to put it back to the way it was out of the box.
You may just ran into an issue with corrupted data in the system file and the system is unable to read.
Here is a link to help you with the Windows System Recovery.

Pls check my current file system of PROD .
Filesystem    GB blocks      Used      Free %Used Mounted on
/dev/prddata1lv    120.00     66.61     53.39   56% /oracle/IRP/sapdata1

1, How much Space is recommended to increase the total space of the sapdata1..4 file system in SAP.
Currently we have assigned 120GB to each datafile. if its any recommendation of sapdata1,2,3,4 total space , how can proceed for further ?
ie ---> is there any limitation to increase the sapdata file system in SAP .
example sapdata1,...4 ---> max limit to increase is 200 GB like that .....
2,secondly only sapdata4 is keep on growing and rest of the file system are not much .
Kindly suggets
Edited by: satheesh0812 on Dec 20, 2010 7:13 AM

Hi,
Please identify what are the activities that were taking place which was consuming your space so rapidly.
Analyze if the same activities are going to be performed in future, if so for how many months.
Based on the comparision of present growth trend you can predict future trend and decide. Also analyze which table/tablespace is growing fast and what were its related data files and where are they located, you need to increase that file system to high level rather increasing all file systems sapdata1...4.
Based on gathered inputs you can easily predict future growth trends and accordingly increase your size with additional space of 10%.
You can increase your file system there is no limitation such, but you will face performance related problems. For this you need to create a separate tablespace and move the heavily growing table data files into that table space with proper index build.
Regards.

Event ID 55 NTFS Error: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume.

One of our File Server getting this error. I explained to you what happened. One of the HDD has failed from this server, which is on RAID. So we put the new one. But we get the NTFS Error. We make the schedule to run the chkdsk /r /c. But still we get this
error on events viewer. Now i have the other problem is that this system's backup is taken care by Dell AppAssure application. this application took the snapshot of each hdd. but due to this error it stops. So I talk to the Dell person to resolve the problem,
but he said to resolve the problem of the NTFS Error. If you resolve this issue the application will work.
So can anyone please help me ASAP to resolve this issue? My sever operating system is Windows 2003 R2.
Thanks.
don

Doesn't the "/c" argument skip directory corruption tests? Have you tried just using "chkdsk /r" ?
The /I or /C switch reduces the amount of time required to run Chkdsk by skipping certain checks of the volume.

SAP file system restoration on other server

Dear Experts,
To check that our offline file system backup is successful, we are planning to restore the offline file system backup from the tape on to a new test server.
Our current SAP system (ABAP only) is in cluster with CI running on one node (using virtual host name cicep) & DB running on another node (using virtual host name dbcep).
Now, is it possible to restore the offline file system backup of the above said cluster server on to a single server with a different host name?
Please help on this.
Regards,
Ashish Khanduri

2. Is it possible to directly backup the filesystems (like /dev/oracleGSPlv)? This requirement is because, when I backup (using tar) /oracle, all the folders in /oracle, like /oracle/GSP, /oracle/GSP/sapdata1 etc, are also backed up. I do not want it. I would like to backup the filesystems directly.
3. Which unix backup tools are used to backup the individual filesystems?
4. How do we restore the filesystems to the test server?
Thanks for your advise.

Can we store ORACLE DATA and LOG files in seperate file system

I am installing NW2004s in HP UNIX Server with Oracle database
I have selected the option as custom
I would want the SAP datafiles to be stored in /sapdata file system
Log files to be stored in /oraclelog file system
While installation SAP is just asking me for the location of SAP data files. It is not asking me for the location of the log files.
(It is asking me for the location of control files)
Hence as per my understanding the oracle log files can be saved only in the same directory as oracle Data file.
Please confirm

I have heard reports of people that made some kind of synchronization between AD and OID, but I have no hands on experience with this. There are some notes on metalink that describe the process, but I try to stay away from AD as far as possible (I usually work on unix or linux environments and those don't really mix with AD).

_NTFS - File system corrupt

A couple of weeks ago I purchased a new Seagate HDD because the old hard disk was failing. Now I get a message every day in the event viewer that the NTFS file system structure on the disk is corrupt and unusable. I have run checkdisk several
times, but the message keeps reappearing. I also downloaded Update for Windows 7 for x64-based Systems (KB982018), but I still receive the message. I do not know how to delete shadow copies on C:.

Hi,
What is the result of chkdsk command?
Generally, if you got a corrupted disk, in the result of chkdsk output, you need get information about disk fault.
If this is a hardware issue, please contact the device manufacture for more help.

SAP Backups ; R/3 & file system

Hello,
What is the different between SAP R/3 backup and SAP File System backup?
what are the files that backing up in each cases
To which back up does the oracle DB fit in. (Data Files,Control files, Redo Logs, SPFILE)
To which back up does the O/S files fit in. (here Suse O/S)
thankx

There is not any concept of SAP file system backup.....it means OS level file system backup.
SAP R/3 backup can backed up all the sapdata(database) files, controlfiles as well as redologs.
OS filesystem level backup can backed up all the files based on your requirement and rotation.
Both backups you can use for restorations.....SAP R/3 backup will take all the responsibilities in backup as well as in restoration.
but in OS level backup first you must know which files need to be backed up and what exactly the all directoruies contains.

Archive Repository - Content Server or Root File System?

Hi All,
We are in the process of evaluating a storage solution for archiving and I would like to hear your experiences and recommendations. I've ruled out 3rd-party solutions such as IXOS as over kill for our requirement. That leaves us with the i5/OS root file system or the SAP Content Server in either a Linux partition or on a Windows server. Has anyone done archiving with a similar setup? What issues did you face? I don't plan to replicate archive objects via MIMIX.
Is anyone running the SAP Content Server in a Linux partition? I'd like to know your experience with this even if you don't use the Content Server for archiving. We use the Content Server (currently on Windows) for attaching files to SAP documents (e.g., Sales Documents) via Generic Object Services (GOS). While I lean towards running separate instances of the Content Server for Archiving and GOS, I would like to run them both in the same Linux LPAR.
TIA,
Stan

Hi Stanley,
If you choose to store your data archive files at the file system level, is that a secure enough environment? A third party certified storage solution provides a secure system where the archive files cannot be altered and also provides a way to manage the files over the years until they have met their retention limit.
Another thing to consider, just because the end users may not need access to the archived data, your company might need to be able to access the data easily due to an audit or law suit situation.
I am a SAP customer whose job function is the technical lead for my company's SAP data archiving projects, not a 3rd party storage solution provider , and I highly recommend a certified storage solution for compliance reasons.
Also, here is some information from the SAP Data Archiving web pages concerning using SAP Content Server for data archive files:
10. Is the SAP Content Server suitable for data archiving?
Up to and including SAP Content Server 6.20 the SAP CS is not designed to handle large files, which are common in data archiving. The new SAP CS 6.30 is designed to also handle large files and can therefore technically be used to store archive files. SAP CS does not support optical media. It is especially important to regularly run backups on the existing data!
Recommendation for using SAP CS for data archiving:
      Store the files on SAP CS in a decompressed format (make settings at the repository)
       Install SAP CS and SAP DB on one server
       Use SAP CS for Unix (runtime tests to see how SAP CS for Windows behaves with large files still have to be carried out)
