Correct steps to reload ASM disks into a running ASM instance on Linux RHEL
Hi guys,
i hope this is the correct forum, awfully i did not found any document specifically talking abou this.
first of all let me explain quickly my goal: in my server (it contains the same data of 3 production RACs for reporting purposes) i would like to shutdown a single instance (i have 3) and realod his disks to refresh the data or because for some reason its mount into ASM is failed.
this is a mix of Oracle ASM and Linux stuff...
on this server there is a shell script that perform the following steps:
1) shutdown 3 instances of 11g (11.2.0.2.0 with patch for asm already installed for bug... dont remember)
2) shutdown ASM instance
3) stop ASMLIB
4) stop multipathd
5) remove all disks devices from linux
6) take a snapshot on the 3 production RACs
7) remap the disks to this server (SAN stuff)
8) rescan the disks
9) start ASMLIB
10) start ASM instance
11) mount the DiskGroups
12) start 3 oracle instances
this works fine... my problem is when i try to refresh the disks of just 1 of the 3 instances, i perform the following steps:
1) stop instance ABC
2) dismount ABC diskgroups related to ABC instance
3) wait 5 seconds (dont ask... if idid it without ASM still have the disks locked)
4) delete the ASMLIB disks (oracleasm deletedisk XYZ) relate to such diskgroups
5) remove mpaths related to the disks that need to be refreshed or correctly mounted oneagain
6) remove devices
7) unmap disks on SAN
8) take snapshot (clone disks)
9) map disks from SAN
10) delete bindings file
11) rescan devices
12) execute multipath command (to rebuild bindings file)
13) execute oracleasm scandisks
14) mount DiskGroups
15) start instance ABC
actually i dont understand why the OS (or specifically ASMLIB) do not recognize me anymore one of the ASMLIB disk
do you have any idea ? or im completly crazy doing that ?
best regards,
Luca
Hi,
well this step
4) delete the ASMLIB disks (oracleasm deletedisk XYZ) relate to such diskgroups
is not good. Because it will clear the ASM Header and as a result ASM will never again be able to detect the disks.
So it is clear that "scnadisks" later will not see the disks, because you wiped them.
Worse: You did the snapshot after deleting them... this gets tricky to get them "repaired" again.
However there is the possibility to relabel a dropped ASM disks. You need to open an SR for this, since the procedure to restore the lost ASM header is not that simple..

Difference between ASM Disk Group, ADVM Volume and ACFS File system
Q1. What is the difference between an ASM Disk Group and an ADVM Volume ?
To my mind, an ASM Disk Group is effectively a logical volume for Database files ( including FRA files ).
11gR2 seems to have introduced the concepts of ADVM volumes and ACFS File Systems.
An 11gR2 ASM Disk Group can contain :
ASM Disks
ADVM volumes
ACFS file systems
Q2. ADVM volumes appear to be dynamic volumes.
However is this therefore not effectively layering a logical volume ( the ADVM volume ) beneath an ASM Disk Group ( conceptually a logical volume as well ) ?
Worse still if you have left ASM Disk Group Redundancy to the hardware RAID / SAN level ( as Oracle recommend ), you could effectively have 3 layers of logical disk ? ( ASM on top of ADVM on top of RAID/SAN ) ?
Q3. if it is 2 layers of logical disk ( i.e. ASM on top of ADVM ), what makes this better than 2 layers using a 3rd party volume manager ( eg ASM on top of 3rd party LVM ) - something Oracle encourages against ?
Q4. ACFS File systems, seem to be clustered file systems for non database files including ORACLE_HOMEs, application exe's etc ( but NOT GRID_HOME, OS root, OCR's or Voting disks )
Can you create / modify ACFS file systems using ASM.
The oracle toplogy diagram for ASM in the 11gR2 ASM Admin guide, shows ACFS as part of ASM. I am not sure from this if ACFS is part of ASM or ASM sits on top of ACFS ?
Q5. Connected to Q4. there seems to be a number of different ways, ACFS file systems can be created ? Which of the below are valid methods ?
through ASM ?
through native OS file system creation ?
through OEM ?
through acfsutil ?
my head is exploding
Any help and clarification greatly appreciated
JimQ1 - ADVM volume is a type of special file created in the ASM DG. Once created, it creates a block device on the OS itself that can be used just like any other block device. http://docs.oracle.com/cd/E16655_01/server.121/e17612/asmfilesystem.htm#OSTMG30000
Q2 - the asm disk group is a disk group, not really a logical volume. It combines attributes of both when used for database purposes, as the database and certain other applications know how to talk "ASM" protocol. However, you won't find any general purpose applications that can do so. In addition, some customers prefer to deal directly with file systems and volume devices, which ADVM is made to do. In your way of thinking, you could have 3 layers of logical disk, but each of them provides different attributes and characteristics. This is not a bad thing though, as each has a slightly different focus - os file system\device, database specific, and storage centric.
Q3 - ADVM is specifically developed to extend the characteristics of ASM for use by general OS applications. It understands the database performance characteristics and is tuned to work well in that situation. Because it is developed in house, it takes advantage of the ASM design model. Additionally, rather than having to contact multiple vendors for support, your support is limited to calling Oracle, a one-stop shop.
Q4 - You can create and modify ACFS file systems using command line tools and ASMCA. Creating and modifying logical volumes happens through SQL(ASM), asmcmd, and ASMCA. EM can also be used for both items. ACFS sits on top of ADVM, which is a file in an ASM disk group. ACFS is aware of the characteristics of ASM\ADVM volumes, and tunes it's IO to make best use of those characteristics.
Q5 - several ways:
1) Connect to ASM with SQL, use 'alter diskgroup add volume' as Mihael points out. This creates an ADVM volume. Then, format the volume using 'mkfs' (*nix) or acfsformat (windows).
2) Use ASMCA - A gui to create a volume and format a file system. Probably the easiest if your head is exploding.
3) Use 'asmcmd' to create a volume, and 'mkfs' to format the ACFS file system.
Here is information on ASMCA, with examples:

TT Issue "9994 Loading data store from disk into RAM in progress"
Getting this strange issue. Sometimes (2-3 times a day) TT just becomes unavailable and when trying to connect to it getting "9994 Loading data store from disk into RAM in progress".
Any advise on what the root cause for this behavior might be?In all likelihood this is exactly what it sounds like - your datastore is being reloaded from disk into memory. Connections can't be completed until the datastore has gone through recovery and is fully in-memory. You need to look back through your ttmesg.log files and find out why the datastore was taken out of memory in the first place. Possibly there's been a crash and it has been invalidated, meaning it needs to be recovered from the checkpoint files and transaction logs. Or maybe there were no user connections and it was taken out of memory and checkpointed to disk in a normal, controlled fashion. The ttmesg.log files will tell you what happened.

Hi,
A few days ago, I have asked a question about“ASM disk header corruption”at ASM disk header corruption .
Because it was only my assumption, I didn't think about it deeply. This morning I encountered a problem from a thread. It said that the diskgroup couldn't mount, and ORA-15196 appeared in the alert.log.
It occurred to me that if the diskgroup couldn't mount and the header of an asm disk corrupted, how should I deal with it? Will the data in the ASM disk be lost?
Please help me with this problem.
Thanks in advance.user526904 wrote:
I hope you have the backup, Incase its the media failure and if you can detemine the corroupt datafiles, just restore the corroupt datafiles from backup and recover them. Database backups cannot restore a corrupted ASM header. rman backups the Oracle data files. Not the physical ASM disk itself with the disk's headers.
To restore that, you will need a physical disk backup. A physical disk backup will need all processes using the disks to terminate in order to ensure that all file handles are closed and that the backup is consistent. Not something that is easily done in today's 24x7 environments. RAID is usually used to address this type of failure (e.g. via hot swappable disks, where you simply replace the faulty disk with a new one, while the storage system is running).
So where you do not have that physical redundancy, and have to deal with "physical disk" error (like corrupted header blocks), you need to be extremely careful on how to try and recover that. I would not even try and touch that disk. I will ensure that no processes touch that disk at all, create a duplicate disk (same size) and manually "mirror" the data (using dd for example). This will serve two purposes. Tests whether physical reads on the problem disk succeeds (is this actual media failure, or logical failure?). And create a 2nd disk that can be used for testing/playing purposes, prior to trying any fixes on the problem disk. -
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
Scanning the system for Oracle ASMLib disks: [ OK ]
# /etc/init.d/oracleasm listdisks

Here is whats going on in /var/log/messages when I run the oracleasm scandisks command

At this point I don't want to click the OK until I am sure someone is in the office to reboot the machine manually if I do hang it again.... I hung it twice yesterday, however I did not have the devices excluded in the oracleasm configuration file as i do now
Edited by: user10193377 on Aug 14, 2009 3:23 PM
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 inHi 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,

ASM Disk preparation for Datafiles and FRA in Oracle 10g RAC Inst
Dear Friends,
Please clarify wheteher the below method is correct to confiure ASM disks for Datafiles and FRA
Partitions provided by IT team for OCR and Voting Disk
/dev/sda1 - 150 GB (For +DATA)
/dev/sda2 - 100 GB (For +FRA)
OS : RHEL 5.6 (64 Bit)
kernel version = 2.6.18-238.el5
Steps:(Node1)
1) Install the RPM's for ASM
rpm -Uvh oracleasm-support-2.1.7-1.el5.x86_64.rpm
rpm -Uvh oracleasm-2.6.18-238.el5-2.0.5-1.el5.x86_64.rpm
rpm -Uvh oracleasmlib-2.0.4-1.el5.x86_64.rpm
2) Configure ASM
/etc/init.d/oracleasm configure
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
3) Cretae ASM Disk
/etc/init.d/oracleasm createdisk DISK1 /dev/sda1
/etc/init.d/oracleasm createdisk DISK2 /dev/sda2
4)/etc/init.d/oracleasm status
5)/etc/init.d/oracleasm scandisks
6)/etc/init.d/oracleasm listdisks
7) Nothing to perform on Node2
8) In dbca choose ASM and map the DISK1 for datafiles and DISK2 for FRA
Please confirm the above steps are right?if not please clarify
If DBCA ->ASM doesn't discover my disk then what should be the Discovery path i have to give?
Please refer any document / Metalink ID for the above complete process
Can i have ASM and oracle DB binary in the same home

I have downloaded Adobe Photoshop digitally but when I activated adobe I keep getting this error message Adobe Premiere.exe - NO DISK - There is no disk in the drive. Please insert a disk into drive/device/harddisk/DR1
It sounds like you downloaded the wrong application, namely Adobe Premiere Elements.
If you meant Adobe Photoshop Elements, you're in the wrong forum. This is not the Elements forum.
Here's the link to the forum you want:
https://forums.adobe.com/community/photoshop_elements/content
If you mean Photoshop proper, since you are posting in the Photoshop forum, give version details and your system specs.
BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),

your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,

if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.

Hyperion 9.3.1 Disaster Recovery Steps For Restoring Prod Backups Into QA ?
Hello All:
We run Hyperion 9.3.1.1 (SQL back end) and I was wondering what the correct steps are for restoring sql backups from PROD into QA?
Does anyone have any experience with this? I've tried it out and can't get the QA system to come up after the restore of the PROD bak files. When I try to log into the QA workspace after the restore, it errors saying I need proper username/id....even when I use the local shared services admin account....like there is a disconnect between workspace and shared services.
Any suggestions are greatly appreciated.....thanks!

The most recent version of iTunes is 9.0.2
Try updating your iTunes software and *then try to Restore the iPhone.*
On your Mac, click the Apple Menu / Software Updates.
After the installation, repair disk permissions.
Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and *restart your Mac*.
Make sure your Windows based machine has the latest version of iTunes also. 9.0.2
Launch iTunes on the PC. If it's not up to date you should see a dialog box asking if you want to updage your iTunes software.

*** Of course there are other LUNs not going to be part of ASM disk groups so it cannot read all of them initially.
Somehow after first looking at the disks and seeing them the first time the permissions are changed back on the disks over to root:root as soon as the GUI sees the disks.
You select the disks that you want in the GUI ( but the permissions have been changed already ) so click Next and wham INS 30508 ...
The Install log shows that kfod is apparently scanning the disks a bunch of time ... but before the error appears install log sees that permissions have changed.
Somehow actions caused from running the GUI are changing the permissions? Something is wrong somewhere ... powerpath ? 11.2.0.3 on this kernel version ? Seems very bizarre ...

Yeah I know probably going to have to open an SR here but some of you guys around here are pretty sharp. Can I attach the whole install log here somehow?Well I am not exactly opposed to udev rules for the powerpath devices ... not that I know what that is exactly ... if this can fix my problem.
I found an example or two from google ...
It looks like on my OL 6.2 system there is a difference in the files ( rules I guess ) under /etc/udev/rules.d

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.

Hi,
We have two Linux hosts accessing EMC SAN LUNs and we have Oracle ASM Disks created on those devices. Both the Linux Hosts (server1/2)are in once Dell Blade Chassis1 and one of the Server we are planning to move to a different Dell Chassis(2) to have redundency in case of Chassis1 faliure. But if we move one server2 to Chassis2 the HBA WWN Number for the host on the new Dell Chassis2 will change ( WWNs are assigned by Chassis on Dell) and the server2 will loose all the SAN LUNs from EMC Array. I will have to rezone the new server WWNs to storage and pesent the same disks again and rescan the disks which will take couple of reboots. During this period EMC LUNs will not be visible to server2 and I would like to what will happen to ASM disks on the server2 and how to I accomlish this goal? Any detailed steps please? This is a production system with oracle 11g running.
This is the output of emc powerpath devices (LUNs) which is same on both the hosts.
[root@server2 ~]# powermt display dev=all | grep emc
Pseudo name=emcpowerl
Pseudo name=emcpowerj
Pseudo name=emcpowerf
Pseudo name=emcpowerk
Pseudo name=emcpowerg
Pseudo name=emcpowerh
Pseudo name=emcpowerm
Pseudo name=emcpoweri
[root@server2 ~]#
This are the ASM disks on both the hosts:
[root@server2 ~]# oracleasm listdisks
DATA01_F1
DATA01_G1
DATA01_H1
DATA01_I1
FRA01_L1
LOG01_J1
LOG01_K1

WWNs are global - not local. If the WWN is foo123 on server1 for EMC LUN1, why would it not also be foo123 on server2 for EMC LUN1? When you move to server3 or install server3, why would EMC LUN1 not have a WWN of foo123 on server3?
I will have to rezone the new server WWNs to storage and pesent the same disks again and rescan the disks which will take couple of reboots. Using Powerpath perhaps - using multipath, not. New devices (LUNs) can be made visible by the kernel my refreshing multipath - no reboot required. If existing LUNs are going to be changed - yes, a single reboot will be needed. But not multiple (unless you have a driver issue with stale connections not being reset on the storage server side).
This is the output of emc powerpath devices (LUNs) which is same on both the hosts.We dropped Powerpath a long time ago. There were compatibility issues between it and AsmLib kernel drivers. Powerpath taints the Linux kernel and limits kernel upgrade flexibility. I refuse to run it on our new clusters. I use multipath instead - the very same s/w used by some of the largest clusters (with Pentabyte storage) in the world. The comfort factor using Open Source drivers (and certified for that kernel version) is significantly higher than installing 3rd party kernel driver binaries - and having to deal with a 2nd party when it comes to o/s and kernel support. -
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.Unfortunately the v$asm_file does not have the entire file name or path it just gives you the follwing...

This really stinks I wish I didn't have to work with 10gr1 at all but the database I am trying to move to a ew server and new storage is running this version and we did not want to upgrade the existing database first before attempting the migration because it is reliant upon tape backups which I do not have alot of confidence in... -
Hi guys, I have a big issue to solve: I work on Solaris OS and Oracle 10.0.2 with ASM.
I can't delete a new (no tablespace are expanded till now) disk added to diskgroup (DGFC).
This is my situation:
select name, state FROM V$ASM_DISK where name like 'DGFC%';
NAME STATE
DGFC_0000 NORMAL
DGFC_0001 NORMAL
DGFC_0002 NORMAL
DGFC_0003 NORMAL
DGFC_0004 NORMAL
DGFC_0005 NORMAL
DGFC_0006 NORMAL
DGFC_0007 NORMAL
DGFC_0008 NORMAL <---- This is the last disk added (I would remove it)
Maybe this could be important: DGFC_0008 was dropped from another diskgroup and header_status has changed from CANDIDATE to FORMER, then I added to DGFC diskgroup in the classic way.
Sending ALTER DISKGROUP DGFC DROP DISK DGFC_0008; the situation change into
NAME STATE
DGFC_0008 HUNG
and log file alert_+ASM.log contains:

Anyone could help ??? Thanks a lotThanks a lot Levi,
The answer was into the Log: disk exhausted. Original diskgroup was quite full and asm can't rebalance correctly the data on the new disk (which datas??!!).
I solved adding a new disk (16GB) and alterering diskgroup DGFC. New space ready and disk dropped correctly.
Thanks a lot

Reinstalling Oracle 11gR2 RAC Grid Problem - ASM Disks Group
Folks,
Hello.
I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer.
I have been installing Grid Infrastructure using runInstaller in the first VM rac1 from step 1 to step 9 of 10.
On the step 9 of 10 in the Wizard, accidentally, I touch the Mouse, and the Wizard is gone.
The directory for installing Grid in the 2 VMs is the same: /u01
In order to make sure everything is correct, I delete entire directory /u01 in the 2 VMs and install Grid in rac1 again.
I have understood it's not the right way to delete /u01. The right way is to follow the tutorial
http://docs.oracle.com/cd/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
But I have deleted /u01 and need to fix one by one. I install Grid again and get the error message on step 5 of 9 as follows:
[INS - 30516] Please specify unique disk groups.
[INS-3050] Empty ASM disk group.
Cause - Installer has detected the disk group name provided already exists on the system.
Action - Specify different disk group.
In Wizard, the previous Disk Group name is "DATA" and its Candidate disks (5 ASMDISKs) are gone. I try to use a different name "DATA2", but no ASMDISKs come up under "Candidate disks". For "ALL Disks", all ASMDISKs cannot be selected.
I want to use the same ASM disk group "DATA" and don't want to create a new disk group.
My question is:
How to have the previous ASM disks and its group "DATA" come up under "Candidate Disks" so that can use it again ?
Thanks.Hi, in case this helps anyone else. I got this INS-30516 error too was stumped for little while. I have 2 x 2-node RAC which are hitting same SAN. The first-built RAC has a DATA diskgroup. When went to build second RAC on new ASM disk new DIskgroup (but same diskgroup name DATA) got INS-30516 about diskgroup name already in use etc. Finally figured out all that was required was to restrict diskstring using button in installer to only retrieve the LUNS for this RAC (this was quick and dirty - all LUNS for both RAC being presented to both RAC). Once diskstring only searched for the LUNS required for this RAC only, e.g.
ORCL:DATA_P* (for DATA_PD and FRA_PD)
the error went away.
I also have DATA_DR and FRA_DR presenting to both RAC. Apparently it scans the header and if it finds a diskgroup name that is already in use based on the diskstring scan it will not allow reuse of the diskgroup name since it has no way of knowing that the other ASM disks are for a different RAC.

Error Msg - There is no disk in the drive. Please insert a disk into drive
Okay, I have been using itunes w/the same ipod for quite a while. Recently my computer died so I just bought a new one. Before getting rid of the old one I logged onto windows and moved all my files to an external drive. I am now using this external drive for all my docs, music, etc. on the new computer and did a "move" of "my documents" (including "my music" contained therein). I installed itunes and my ipod using the software disks that came with my ipod. I inserted the ipod and it worked fine but it did make me associate the ipod with this new computer and had to reinstall all my music on my ipod. So far so good. Then when I went to play a purchased song itunes informed me that I had to upgrade to the most recent version of itunes to play the song. I then dowloaded the update and installed it. After installing the updated itunes, itunes then basically re-associated itself with my ORIGINAL profile (I'm not sure if profile is the correct word to use here) and once again deleted everything on my ipod and reinstalled all my songs. Now this is where I began having this problem. Now, everytime I run itunes (with or without my ipod connected) I get 12 of the above-mentioned error messages. The top of the box says "Windows - No Disk" and the main part of the box says "There is no disk in the drive. Please insert a disk into drive." I am given the choice of "Cancel" "Try Again" and "Continue." I hit cancel for a total of 12 times. I've tried with disks in both of my cd/dvd drives and get the same message. The funny thing is that I have about 12 or so card readers (scene by the computer as drives) and I'm thinking that maybe itunes is trying to access those drives or something, but I'm not sure. So, that's it in a nutshell. Any help by someone w/knowledge of this issue would be greatly appreciated. Thanks.
This can also be caused in iTunes 7 by "dead tracks": songs that iTunes is expecting to find in a certain place but the song file isn't there.
I recently upgraded to version 7 and got this message every time I started iTunes. I used the iTunes COM SDK for Windows with JScript to find all the dead tracks in my library. Then I fixed them by either deleting them from the library or else correcting the library's idea of where the song file was. Once I did this the message went away.
Another way to look for dead tracks is to parse the iTunes library XML file and look for invalid file paths. I did this in Perl without too much trouble.
(I'm cross-posting this to several threads about the same problem.)
