Scripting the Removal of Physical disk from VM

Hi all
I have read this thread here which has helped me so far to create a script for the removal of a VM Hard Disk Drive
http://social.technet.microsoft.com/Forums/windowsserver/en-US/7f00687c-aa8b-4125-a10c-2730ee473e78/auto-add-remove-physical-disk-from-hyperv-vms?forum=winserverhyperv
So far the script I have knocked up is as follows:
Remove
PS C:\Users\Administrator> remove-vmhardDiskDrive -VMName 2012r2 -ControllerType SCSI -ControllerNumber 0 -ControllerLocation 0
Re-add
PS C:\Users\Administrator> add-vmhardDiskDrive -VMName 2012r2 -ControllerType SCSI -ControllerNumber 0 -ControllerLocation 0
This gets me this in the Hyper-V settings:
I need the script to add the VM Hard Disk drive in with the physical hard disk selected automatically.
Is there a way to do this?
As you can see I am not a powershell expert, im not even an "expert"
Thanks - Dan

All done
The script I used for the removal and then re-adding of the physical disk is as follows:
remove-vmhardDiskDrive-VMName2012r2-ControllerTypeSCSI-ControllerNumber0-ControllerLocation0
Add-VMHardDiskDrive-VMName2012R2-ControllerTypeSCSI-ControllerNumber0-DiskNumber1-Passthru
I then automated it with task scheduler to trigger at 6pm everyday (30 minutes after rotation time)
The ISCSI controller type allows you to run the command whilst the VM is on.

Storage Spaces - Remove Physical Disk from Simple layout

I am running Server 2012 RTM with a single storage pool containing 4 drives - 2.73TB, 1.36TB, 465GB and 148GB. There is a single virtual disk created, with thin provisioning, using the Simple layout, with a current maximum size of 2.73TB, and with 1.32TB
allocated. I want to remove the 148GB drive and replace it with a 465GB drive. When I right-click the 148GB disk and select Remove, I get a warning that Windows will attempt to rebuild any virtual disks that store data on the disk I'm trying to remove, and
that in order to succeed, the storage pool must have enough free space to accommodate the data from the disk I'm trying to remove. There is more than enough space in the virtual disk to accommodate whatever files may be stored on the 148GB disk - over 1TB
unallocated. However, when I confirm that I want to remove the disk from the pool, I get the following message:
This physical disk is used by one or more virtual disks that use the Simple (no resiliency) layout. To remove this physical disk, delete the following virtual disks: Simple
Surely the fact that it's a simple volume (rather than mirrored/parity) shouldn't affect the ability to move the data off the disk? It appears that disk removal is implemented as a simulated drive failure, forcing a rebuild of the resiliency data, rather
than by simply moving the data off the disk onto other available disks.
Additionally, after I've attempted to remove the disk, it's now been marked as 'Retired'.
Is there any simple way to remove this disk?

Same problem here, but I have some workaround for the problem.
But, even in Windows Home Server with its awesome disk extender (predecessor of Storage Spaces) you had to take the shares (meaning volumes in our case) offline so you could take out the disk from the pool.
Agree that it would make more sense to be able to remove disk from the pool online and the technology is most likely is already there: online cluster moves with defragmentation API was there for years and ReFS moves clusters online when it detects disk errors.
Anyway here is the process that may work for you if taking volume offline is an option in your case:
Try to remove physical disk in Server Manager - it will fail with abovementioned error, but the disk will go into "Retired" state.
Now provision a new Virtual Disk and a volume of your choice. Most likely you will pick the same disk and volume type as you already had, but this is the chance to change the topology. You should be able to do this since you have a lot of physical disk
space, especially if you used Thin provisioning.
It looks like at this point retired physical disk is not included into the new Virtual Disk provisioning, but it is still accessible via existing virtual disk.
Copy over all files from your old volume to a new volume.
Now delete old Virtual Disk.
If you want - change disk name and volume letter of new virtual disk that you created and new volume to what you had before.
Now in Disk Manager take failing physical disk offline.
Replace failing disk, initialize new disk and add it to the pool.
Note: for me sometimes removing disk in via Storage Pool management GUI does not mark it as "Retired". In this case you can open PowerShell as Admin and assuming you want to remove PhysicalDisk2 - run the following command:
Set-PhysicalDisk -FriendlyName PhysicalDisk2 -Usage Retired

thanks for your prompt response.
I am aware of that we can't use any free spaces where the VM is installed.Hence the additional storage added to the server.
1. Install VM Server on 80GB HD ( /dev/sdb)
2. Later, i added 500GB to the storage ( no installation - just the disk ) ( /dev/sda)
Same configuration worked fine in 3.0, now i am not able to identified the additional disk which was added later with 3.2.1.

Can I move the OS X boot disk from a core 2 duo mini to a new i5 mini and have it boot and run normally? Some info suggests I can.

I have a 2.53ghz core 2 duo mac mini. I just purchased an i5 2.5ghz mac mini (with amd 6630m graphics).
Can I simply ermove the OS X boot disk from the core 2 duo mini and put it into the i5 mini and have the it boot up and run fine?
Some info I read suggests I can do this and it should be no problem and will work fine.
I am running 10.9.3 of OS X.
Thanks.

- I would connect the two via FireWire
- Boot the new one Target Disk Mode
- Boot the old one in Recovery
OS X: About OS X Recovery
and then uses disk utility to restore the HD on the new computer from the starup disk of the old one.
You could also boot the old one normally, download SuperDuper and the clone the old one's startup disk to the new one.

Is there anything that I can do to remove a stuck disk from the cd drive?

I have an install disk that will not eject from my Macbook Pro. Is there anything that I can do myself?

Force eject a stuck cd/dvd
First try the normal methods to remove the disc. Drag its icon to the Trash can in the Dock or select 'Eject' from the File menu.
If you are running a virtual machine, e.g. VMFusion, ensure that the CD is disconnected from the virtual machine. This will sometimes allow the CD to now show up in Mac OS X.
Shut down the computer and start up whilst holding down the mouse button. This may take some time, but keep your finger on the mouse button right up until the disc comes out or the log-in screen has appeared.
If you have Toast Titanium installed on your computer, choose EJECT DISC from the menubar.
Sometimes you can successfully use the eject disc button in iTunes even if the disc is not visible to the Finder
Open Disc utility and choose the disc you wish to eject in the left-hand pane, then click on the Eject button.
Some Macintoshes have a paperclip hole that you can insert a straightened paperclip into, manually triggering the eject mechanism.
Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray.
If your computer has an eject button on the keyboard, restart the computer holding down the Option key. When the startup disk selection screen appears, let go of the option key and press the keyboard's eject button.

Is it possible to automate/script the removal of workflows from workflow archive?

We don't allow our CQ authors to activate content directly. They must activate their content by executing a custom approval workflow we'd developed as part of our first CQ project. As you can imagine this workflow is run very often. So much so that when it came time to upgrade from CQ v5.4 to CQ v5.5 there were too many for me to purge the workflow archive and leaving all those workflows in place caused the upgrade process to run for a very long time. At the time I was provided with a package for the CQ v5.4 environment that once installed provided a component (/apps/tools/components/purgewf/run.html) that I could then then leverage to kick off a process that given enough time would purge all of the workflows from the workflow archive.
Now that we are on CQ v5.5 I'd like to be proactive and develop a script that I can schedule to execute on a regular basis that would basically do the same thing as that component from CQ v5.4. Does anybody know if there's an easy way to do this with CQ v5.5? Could I simply install the same component that I was given for CQ v5.4 and then leverage curl to kick the process off as I've done that sort of thing before to kick off JMX operations such as runDataStoreGGarbageCollection. This wouldn't be a JMX operation but I'm thinking it migh actually be easier to use curl to kick of something like purgewf/run.html though I'm not really sure what I'm basing that on other than instinct.

This has proved very helpful thank you.
Although I've one point of clarification I could still use some help with. The document provided by Sham, HC mentions within that it's possible to clean up workflows that have had a status of RUNNING for more than 1 day but it seems to be saying its neccessary to create a list of those workflow models you want this feature of the purge mechanism to act on. I've looked the Felix configuration over and I can't see that any of the properties there would accept a list of workflow model names and I've tried all of the various modes that are available for the process and none of them do this automatically by assuming any sort of default value for this list. Is this capablity really there? Not that I see the ability to purge RUNNING workflows as critical functionality for the purge process as the number of problem workflows with this status tends to be managable but if yet if there's a way to make it do it in addition to clean out the archive it would be nice.

Time Machine - how to remove a dead disk from Preferences?

Time Machine Preference pane shows me 3 disks to back up to. One of these, Drive1 , has not been backed up to for months. It always shows as waiting to backup. That is because it is dead. It has been replaced by Drive3. Preference Pane shows Drive1, Drive2, Drive3.
How can I delete Drive1 from Preference Pane? It will always give me the Time Machine Error: "the backup drive is not available"
Can't see a way of doing this.
All suggestions appreciated.

Eric, thank you. That looks exactly like what I want to do. But .. I can't see how to do this.
Here's a screen shot of Time Machine Preferences. I want to delete "Vault1" because I lost the disk 2 months ago. I can't.
You show an action that I don't have available to me. My set up is Software OS X 10.8.2 (12C60)

Time Machine;cannot remove my backup disk from exclude list

So I had to recently back up my computer in order to get a new hard drive for my 2009 macbook. When I went to put everything back onto computer I accidentally said "don't use this backup".Now it's stuck on exclude list in Time Machine.It's greyed out and I cannot take it off!
(ps. I know there was a previous topic on this but it's closed and didn't have helpful information;yes I went to disk utility and did Command+I not helping)
I have school documents on there so I need to be careful on what I do!

Answering "No" to that prompt doesn't prevent you from using the drive as a backup disk; it just stops that from happening automatically. I suggest you watch a video to familiarize yourself better with Time Machine:
Mac OS X: Time Machine Basics
Any other questions you have should be answered in this support article:

Remove 8 cm disk from drive?

I get it now. Using anything other than 12 cm disks won't work. The 8 cm disk is stuck. None of the suggestions work (like restarting with eject button held down; using a paperclip on the ? reset button while computer sleeping). I can't get the smaller disk out. Am I looking at a trip to the repair store? .... any help would be much appreciated. Thanks.

From what I remember from upgrading my ram, the drive is sealed. If you can't shake it out (gently!) and want to preserve your warranty, I would take it in.
Sorry

Removing a minature disk from disk drive

I tried inserting a minature dvd / cd into my Mac Book Pro' s drive and the drive never grabbed it nor will it push it out. Is there a way to force the drive to eject?

You can't use that type of CDs on a MacBook Pro.
Although I think you won't be able to eject that disc, open Terminal and type:
drutil eject
If it doesn't work, press the trackpad while your computer is starting. If nothing works, take the Mac to an Apple Store to get the SuperDrive replaced

How to map ASM disk path to physical disk on AIX?

Hi Everyone,
I am working on a plug-in for Oracle Enterprise Manager 10gR2 on AIX 5.3 which provides monitoring of storage arrays and supports ASM databases in addition to the 'emrep' database. One of the metric of that plug-in is populated by the result from a korn shell script. The script directly runs on the AIX host (connected to the storage array by FC cables via HBA ports) and retrieves the mapping for -- Physical disk - Logical Disk - LUN - ASM Disk.
Now, I was able to get the mapping for Physical Disk – Logical Disk – LUN, but could not map ASM Disk. I googled a lot for any clue but did not find the answer to this specific problem.
Now, I have the list of physical disks used for ASM by the command—
lspv
hdisk0 0001c22ac8d664ca rootvg active
hdisk1 0001c22aa51f496a Oracle active
hdisk2 0001c22ac478263a scratch active
hdisk3 0001c22ac472549a Oracle active
hdisk4 0001c22ac4725d6a Oracle active
hdisk5 none None
hdisk6 none None
hdisk7 none None
hdisk8 none None
hdisk9 none None
hdisk10 none None
hdisk11 none None
hdisk12 none None
hdisk13 none None
hdisk14 none None
hdisk15 none None
hdisk16 none None
The disks hdisk5-16 are ASM disks and there are no PVID’s present.
I also have the list of ASM disks by the command—
ls –l /dev | grep oracle
crw-rw---- 1 oracle dba 22, 6 May 12 00:02 asm_rd10_1a
crw-rw---- 1 oracle dba 22, 10 Apr 21 07:27 asm_rd10_1b

crw-rw---- 1 oracle dba 22, 11 Apr 24 07:34 asm_xbb2_rd10_1b
crw-rw---- 1 oracle dba 22, 13 May 09 13:53 asm_xbb2_rd10_1c
crw-rw---- 1 oracle dba 22, 16 May 12 00:02 asm_xbb2_rd5_1a
crw-rw---- 1 oracle dba 22, 14 Apr 24 07:34 asm_xbb2_rd5_1b
crw-rw---- 1 oracle dba 22, 15 May 09 13:54 asm_xbb2_rd5_1c
Now I am looking for a way to map these two lists with each other, and had no luck so far.
Does oracle provide this information somewhere in the OEM installation structure or is there a command in AIX which could give some way to map the ASM disks to the physical disks?
Any help on this is greatly appreciated. Thanks in advance…
FYI: ASMLib driver is not present on the system.

The view you are talking about here gives the ASM DISK NAME (like DGRXBB_0001) and ASM DISK PATH (like /dev/asm_rd_10_1a) and I am already using it, but this is not what I asked in mt original post. If you read carefully, I want to establish a mapping between the ASM DISK PATH (like /dev/asm_rd_10_1a) and the AIX Physical disk (like /dev/hdisk5) and did not find any view giving this info. If you know of some views which could help establish this mapping or some AIX commands or files that could help do this using shell script, it is most welcome

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.

The Elements 12 Mac disk works fin - I also have a Dell, and the Windows disk will not run at all, sounds like it's grinding, and is almost impossible to remove from the hard drive. I cannot find any place to tell me who to CALL to ask for a replacement!

Hi Samcat,
You can use a download instead of the disk as an alternative: Adobe - Download free trial version Adobe Photoshop Elements 12 | Adobe you can license with your serial
Please test the disk in another windows machine to check if it's caused by the drive or the disk. If you tested with 2 drives please start a support case, i assume Adobe will only provide downloads at this point. They are the same as the trials. If you still need a disk you can burn the trial to a disk as a backup disk. Good luck!
