Recovery of data after ASM Disk fails

OS : Sun Solaris
DB: 10.2.0.3 RAC (2 Nodes)
Are there any steps to be followed for recovery of data after ASM Disk fails?
We are using a 2 Node RAC with ASM normal redundancy. Say if one disk of a diskgroup fails, then what steps we need to follow to make sure that Database is aware of the new disk ?

you said you are using NOrmal Redundancy, which is 2 way mirroring. So with that said, your data should be fine as one only disk has failed and got mirrored. So once you replace to disk, oracle should pick that up and move to data back into it....BUT NOT QUIET SURE, just an opinion.

Recovery data after crash DISK

Hi,
Instance PROD
AIX 5.2
DB 10.2.0.4
Suddenly database server disk crashed.
AIX teams are trying to recover the disk. My question is after recover the disk by AIX admin what steps to follow to make consistent database at DBA side. What issues could arise to come out at the side of database after recover the disk or replace the disk.
Thanks

is the disk full?
--97% full(35 gB free)
is disk available.
--yes disk is available.
I am not able to connect to database with sys user(find below error) but from dev14 user it is connecting and some query is running some not.

Trying to salvage iCal data after hard disk failure!

Hi all,
I had a major hard disk failure recently, and also discopvered that my regular backups weren't including my iCal data! Eek! All that info I use for tax records gone!
Anyway, the wonderful DiskWarrior managed to salvage a drive that was not visible to the naked eye and it recovered various pieces of information. Many of these pieces seem to be re-packaged, or should I say 'Un-packaged'. I have a heap of folders of files that are probably supposed to be within another file structure to be useful to iCal.
I have a few folders with very long names (such as EBD6EF28-1595-49DD-8AEA-8525C9F2CB55.calendar) these have the corestorage.ics
Info.plist
Index files in them, so appear to be the /App support/iCal folders, with a file extension added?!
Also I have folders called the same as the .calendar folders above (but no extension) and these are filled with events like this:
FEAD3FA1-FC1B-4D5B-8C3B-2AB72EA87DF7%2F-.icalevent
FDDD239C-6B90-11DA-B375-00039383DFDE%2F-.icalevent
In textEdit I can see that these are all my events... so near and yet so far. If all else fails I will store these for records.
I can get Calendars to appear but iCal 2.0.5 won't open or imprt the event files...
Can anyone suggest how I might restore said structure so that iCal can import them?
Kind regards
Rosie

Well, the structure of an ics file is easy to get (drag an event to desktop and open it with a text editor) and is well-described on the web, but I don't know about the structure of your icalevents, other than what we can see in the plist editor. After trimming out the time zone info, I get this for an ics file:
BEGIN:VEVENT
SEQUENCE:3
TRANSP:OPAQUE
UID:5E87B2F7-CF39-447E-B252-B3BF5F9C4A61

According to Fat Cat's web page PlistEdit Pro is scriptable, so it might be possible to do something with Applescript.

HT1766 Finding a recent backup (Recovering data after app sync fail)

Hi there.
I have searched EVERYWHERE, downloaded programs, copied copies, and I still can't recover my data.
Here's what happened:
On June 15, Before I went on a long trip, I synced my iPhone 4. I'd synced it the day before (June 14), but I wanted to add a new song.
Since I hadn't updated any apps, I unchecked "Sync Apps" in my iPhone's menu in iTunes. I am almost 100% positive that I checked "Keep Apps" when the alert popped up.
(FOOLISH MORTAL.)
We're on the road, and I am horrified to see that all my third-party apps are GONE.
When I get back from the trip on June 18, I rush home to sync all apps, making sure to re-check "Sync Apps". Happy day, they were back...until I realized that all data on my third-party apps was GONE.
Not just preferences and saved passwords...but two years of budget records from my Tip Sheet app.
I decided this whole thing could be easily solved by restoring my phone to the June 14 backup. But where was it? When I went to "iTunes > Preferences > Devices", there were a few backups, but aside from the June 18 backup, all other backups listed were from March and earlier. This made no sense to me, as I back up my device daily, both to my computer and through iCloud (though most recently on my computer, as iCloud started telling me I didn't have enough space to backup - so there's also an older backup on iCloud).
I begin my research and learn that iTunes only rarely creates a brand-new backup treats its backups like Time Machine, in that it updates the backup with only changed information. But, unlike Time Machine, there doesn't seem to be an easy way to access a recent, but not most recent, backup.
All I really want is my data from Tip Sheet, a third-party app, which was apparently lost in the June 15 backup, but must be salvagable. If I go to "Users/[me]/Library/Application Support/MobileSync/Backup", open the most recent backup folder itself, and delete all files in the folder modified after June 14, and then try to restore my phone from that backup, iTunes gives the error message that my "backup is corrupted". When I put the files back in, the backup works, but the data is still not showing up in my app.
HELP ME PLEASE.

Forgot to add:
I did use Time Machine to look into backups, and on June 14 I had backed up using TIme Machine...but the most recent folder in its "MobileSync/Backup" was Last Modified May 15(?!) and, sure enough, when I replaced the old folder with the new and Restored from Backup, the TIp Sheet data was there - from May 15 and before.
A month might not seem like much, but that's a lot of data that would be hard for me to replace. I know that at least part of my June 14 backup is somewhere in the most recent jumbled-number folder of backup files dating back to October 2010, when I got my phone.
Any insight into this matter would be much appreciated.

Please Help - When I try to add ASM Disk to ASM Diskgroup it crashes Server

We are using a Pillar SAN and have LUNS Created and are using the following multipath device: (I'm a DBA more then anything else... but I am rather familiar with linux .... SAN Hardware not so much)
Device Size Mount Point
/dev/dpda1 11G /u01
The Above device is working fine... Below are the ASM Disks being Created
Device Size Oracle ASM Disk Name
/dev/dpdb1 198G ORCL1
/dev/dpdc1 21G SIRE1
/dev/dpdd1 21G CART1
/dev/dpde1 21G SRTS1
/dev/dpdf1 21G CRTT1
I try to create to the first ASM Disk
/etc/init.d/oracleasm createdisk ORCL1 /dev/dpdb1
Marking disk "ORCL1" as an ASM disk: [FAILED]
So I check the oracleasm log:
#cat /var/log/oracleasm
Device "/dev/dpdb1" is not a partition
I did some research and found that this is a common problem with multipath devices and to work around it you have to use asmtool
# /usr/sbin/asmtool -C -l /dev/oracleasm -n ORCL1 -s /dev/dpdb1 -a force=yes
asmtool: Device "/dev/dpdb1" is not a partition
asmtool: Continuing anyway
now I scan and list the disks
# /etc/init.d/oracleasm scandisks

# /etc/init.d/oracleasm listdisks

Well Clicking OK hun it again and I am waiting to get back into it, to see what new information might be gleened
Does anyone have any ideas on what to check or where to look????? Will update more once I can log back in

Hi Mark,
It looks like something is not correct with your raw device partition based on the error messages:
Aug 14 13:52:06 seer kernel: Add. Sense: Logical unit not supported
Aug 14 13:52:06 seer kernel:
Aug 14 13:52:06 seer kernel: sda: test WP failed, assume Write Enabled
Aug 14 13:52:06 seer kernel: sda: asking for cache data failed
Aug 14 13:52:06 seer kernel: sda: assuming drive cache: write through
Aug 14 13:52:06 seer kernel: sda:end_request: I/O error, dev sda, sector 0
It could be a number of things. I would check with your vendor and Oracle support to see if the multipath software drive is supported and if there is a potential workaround for ASM. Sorry this is not quite the solution, but its what jumps to mind based on issues with multipath software and storage vendors for ASM with Linux and Oracle. Have you checked the validation matrix available on Metalink?
Cheers,
Ben

Issue with ASM disk

Hello,
When using database configuration assistant to configure ASM and create disk group, it can't find any disk. I've tried to chage disk discovery path by using 'ORCL:*', '/dev/oracleasm/disk/*' and install procedure is as follow:
TIA,
Step 1 :
# rpm -Uvh oracleasm-support-2.0.3-1.i386.rpm \
oracleasm-2.6.9-42.0.0.0.1.ELsmp-2.0.3-2.i686.rpm \
oracleasmlib-2.0.2-1.i386.rpm
Step 2 :
#vi /etc/sysconfig/rawdevices
add a line
/dev/raw/raw1 /dev/sdb1
To bind the disk devices to the raw devices, enter the following command:
# /sbin/service rawdevices restart

Hi,
Me also facing same issue while creating ASM.
i done what you said,but now also i'm facing same issue. Please find below steps what i did.
1) ]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb7
Marking disk "VOL1" as an ASM disk: [FAILED]
2) then i enter the raw devices in the below directory
]# vi /etc/sysconfig/rawdevices
/dev/raw/raw7 /dev/sdb7
3) then i changed the ownership root to oinstall
4) then i given the permissions to the raw device
5) after that i given the below command
]# dd if=/dev/zero of=/dev/raw/raw7 bs=1M count=100
dd: opening `/dev/raw/raw7': Device or resource busy
6) Then i tried the below way
]# dd if=/dev/zero of=/devsdb7 bs=1M count=100
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 0.077255 seconds, 1.4 GB/s
7) then i tried to create the ASM Diskgroup but again i got same issue.
Can you please give suggession to me it's very important to me
Regards,
Ram

Concerned about possibility of recovery personal data from my old iPhone

I'm concerned about possibility of recovery personal data after applied "Erase All Content and Settings" option on an iPhone or iPad. Does Apple guarantee that no one can recover my personal data after I deleted & reset my old iPhone by the "Erase All Content and Settings" option ?

Welcome to the Apple Community.
You can safely delete the old back up now.

Can't have ASM mark a NFS file as an ASM disk : -is not a block device

Hello,
I’m trying to experiment with ASM for learning purpose. Because I don’t have access to a SAN, I am trying to use NFS files but I can’t manage to have ASM mark those files as ASM disks.
[root@localhost /]# /etc/init.d/oracleasm createdisk ASM_DISK_1 /mnt/asm_dsks/dg1/disk1
Marking disk "ASM_DISK_1" as an ASM disk: [FAILED]
The oracleasm log says: File "/mnt/asm_dsks/dg1/disk1" is not a block device
OK, more context now:
I am trying to install ASM on a RHEL5 virtual machine (on vmware).
[root@localhost /]# uname -rm
2.6.18-8.el5 x86_64
I followed this document:
http://www.oracle.com/technology/pub/articles/smiley-11gr1-install.html until I got stuck at the following command:
/etc/init.d/oracleasm createdisk ...
Now, the NFS filesystem comes from a Solaris 10 system (the only one that's available) running on a physical sun box (this one is not a virtual system).
I have tried many combinations. I tried creating the files on the linux VM, using dd. As root, as oracle. I tried creating them on the Solaris side, using mkfile... no matter what I try, I always get the same issue.
I tried to follow this document: Creating Files on a NAS Device for Use with ASM (http://download.oracle.com/docs/html/B10811_05/app_nas.htm#BCFHCIEC)
But nothing seems to work.
Any idea, recommendations?
Thanks,
Laurent.

Hi buddy,
I guess the metalink note 731775.1 should help You.
In fact the procedure is:
- Create the disk devices on your NFS directory (using dd)
- Adjuste the permissions over those files (in this case, oracle:dba)
- Adjust the ASM_DISKSTRING at the ASM instance and setting the NFS directory in the discovery path
- Verify if they are available at v$asm_disk view
- Create the diskgroup using the the NFS disks that You have created.
Hope it helps,
Cerreia

Installing Oracle 11gR2 RAC Problem: ASM disks

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
At the first time, I create VM rac1. While its OS Oracle Linux 5.6 is booting, initializing ASMLib Driver OK. I create 5 ASM disks successfully using the command:
[root@rac1 /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
Output: Marking disk "ASMDISK1" as an ASM disk: OK
Because the hard disk space of rac1 is not enough to install Database, I create VM rac1 again with bigger hard disk space (30GB). I do everything the same with that at the first time. But this time, While OS Oracle Linux 5.6 is booting, initializing ASMLib Driver failed. I create 5 ASM disks using the same command:
[root@rac1 /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
Output: Marking disk "ASMDISK1" as an ASM disk: failed
But when I use the command:
[root@rac1 /]# /etc/init.d/oracleasm listdisks
Output: ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5
My questions are:
First, can the 5 disks "ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5" be used correctly in spite of Marking disk "ASMDISK1(2 3 4 5)" as an ASM disk failed ?
Second, how to fix OS Oracle Linux 5.6 so that initializing ASMLib Driver OK while booting ?
Thanks.

Folks,
Hello. The issue is solved by myself. Thanks.

28830 write(2, "oracleasm-instantiate-disk: ", 28) = 28
28830 write(2, "Unable to create ASM disk \"ASMDI"..., 56) = 56
We changed /dev/oracleasm/disks to 777 in order to test but we got the same result. Do we need to adjust the permissions to all of the parent directories in the path (/dev/oracleasm/disks)? I've been looking around for anything related to permissions on /dev/oracleasm but the docs don't mention anything. Any help would be greatly appreciated.

From what I understand, you should not set device permissions of /dev/oracleasm since oracleasm takes care of it according to /etc/init.d/oracleasm configure.
The problem in your case seems to be that ASM refuses to initialize and write metadata to your device. Was the device previously used by ASM? ASM will fail to initialize a device that contains previous ASM metadata. To erase the device you will need to use the dd command, e.g. dd if=/dev/zero of=/dev/sdb. Both ASMLib and raw devices require the candidate disks to be partitioned before they can be accessed. To create a partition on /dev/sdb, for instance, type fdisk /dev/sdb and create a standard partition using the defaults. This will create /dev/sdb1 and you can try oracleasm createdisk again.
You may try the above, but anyway, I was not sure how much you can trust your installation. The problem could also be that you installed the oracleasm kernel driver and asmlib software for OEL 5. Oracle Linux 6 includes an oracleasm kernel driver and as far as I remember you must not install another oracleasm kernel driver. Using modprob oracleasm and installing oracleasm support package using yum should do the trick. You may also need to download and install the asmlib package for the Oracle ASM grid install to see the ASM disks.

Cleaning up ASM disk group after failed rman duplicate session?

I am using rman duplicate to create a clone of a production database. The rman duplicate failed in phase 1 (retoration of datafiles) and my datafile are being restored to an ASM diskgroup.
I read in the metalink note Manual Completion of a Failed RMAN Duplicate [ID 360962.1] the following...
Note : From 10g onwards, if duplicate failed during step 1, which is the restore of datafiles, it is probably best to restart the duplicate process. Any files that have already been restored will be skipped and the duplicate process can continue without manual intervention
So I followed the advice in the note and started the rman duplcate script over again from the beggining. I am hoping it will have the intelligence to skip any files that have already been restored but if it is not since this is 10.1.0.3 and I cannot use the asmcmd command to connect to the ASM instance to delete any files that have been created then how can I delete and of the files since the database instance never got created correctly and cannot open?
Any thought on how I can now cleanup the files in the ASM disk group? Also, has anyone started an rman duplicate again after it has previously failed and did it actually skip the files that are already there as stated in the metalink note?
Thanks.

Recover OCR and VOTE disk after complete corruption of ASM disk groups.

Hi Gurus,
I am simulating a recovery situation to perform recover of OCR and Vote files after complete corruption of ASM related disks and diskgroups. I have setup my environment as follows:\
Environment: RAC
OS: OEL 5.5 32-bit
GI Version: 11.2.0.2.0
ASM Disk groups: +OCR, +DATA
OCR, Vote Files location: +OCR
ASM Redundancy: External
ASM Disks: /dev/asm-disk1, /dev/asm-disk2
/dev/asm-disk1 - mapped on +OCR
/dev/asm-disk2 - mapped on +DATA
With the above configuration in place I have manually corrupted +OCR, +DATA diskgroups with dd command. I used this command to completely corrupt +OCR disk group.
dd if=/dev/zero of=/dev/asm-disk1. I have manual backups as well as automatic backups of OCR and Vote disk. I am not using ASMLib.
I followed this link:
http://docs.oracle.com/cd/E11882_01/rac.112/e17264/adminoc.htm#TDPRC237
When I tried to recover OCR file, I could not do so as there is no such diskgroup which ASM can restore the OCR, Voting disk to. I could not Re-create OCR and DATA diskgroups as I cannot connect to ASM instance. If you have a solution or workaround for my situation please describe it. That will be greatly appreciated.
Thanks and Regards,
Suresh.

Please go through the following document which have the detailed steps to restore the OCR
How to restore ASM based OCR after complete loss of the CRS diskgroup on Linux/Unix systems [ID 1062983.1]

Disk utility recovery of files after deleting from external hard drive?

I had downloaded some files to add to an external hard drive, the hard drive was assigned to a pc before adding these files so it wouldn't let me add files from my MacBook..
Had a look around online and made some changes (well thats what I thought) and I was able to transfer files form my MacBook onto the external hard drive.
What I then figured out was that there was nothing left on the hard drive except for the two file sI just transferred..
It turns out I deleted everyting without noticing.
The stpes I followed was to go to disk utility then select the hard drive and click erase (not knowing this would erase evrything).
So now I have two files on my hard drive and no idea how to recover the 'delted' files.
I tried using Disk Drill, which found the files but then it said I need to buy the full version to recover them.
I am wondering if there is any free methods to recover these files at all, any help is appreciated.

The files are still on the drive, and will remain unless and until you overwrite them with new data. So don't write anything more to the drive in addition to the two files you added after reformatting it, and do download the free trial version(s) of one or more data recovery utilities:
Data Rescue 3: http://www.prosofteng.com/products/data_rescue.php
FileSalvage 7: http://subrosasoft.com/OSXSoftware/index.php?main_page=product_info&products_id= 1
Each is offered in a free demo version that will show you exactly what the full version could recover before you have to pay for anything. There are others on the market, but these are the ones I'm familiar with.
To recover data using any such utility, you must have another drive available on which to save the recovered files. Saving them on the same drive they're being recovered from would just overwrite other files that haven't yet been recovered.

ASM CREATE DISK FAILED

i am getting this error while trying to create disk
[root@dbanew sysconfig]# /etc/init.d/oracleasm createdisk VOL1 /dev/sda3
Marking disk "/dev/sda3" as an ASM disk: asmtool: Unable to clear device "/dev/sda3": Input/output error

[root@dbanew sysconfig]#
could any please look into this and help me

try to clear the disk with the command:
dd if=/dev/zero of=/dev/sda3 bs=4096 count=10000
and after that do your createdisk. perhaps there are some infos in the diskheader that prevents
asmlib from doing its work.

     None of the Disk Agents completed successfully.
     Session has failed.
We checked the configuration, tried linking /oracle/client/11x_64 to 10x_64, removing the link and renewing the 10x_64 oracle client, but still Data Protector can't find the library libclntsh.so.10.1. A new system which was installed with Oracle 11.2.0.2 doesn't have any problems with online backups.
Any help is appreciated!

Hi,
did you create the other link according to the upgrade guide (point 5.5) ?
You need to create this link so that BR*Tools
(which is linked to the Oracle 10.2 client)
can use the newer Oracle 11.2 clients.
After the software installation has finished,
create a symbolic link in $ORACLE_HOME/lib as follows:
cd $ORACLE_HOME/lib
ln u2013s libnnz11.so libnnz10.so
or (HP-UX)
ln u2013s libnnz11.sl libnnz10.sl

Second part: For the DP job, there can be set different environment settings inside the DP job.
Did you check if there are still relicts from the previous release ?
You could integrate a small pre-exec script into the job and let it plot the output of
id
env
set
to a logfile, just to see which values the backup is using.
