Move RAC database - need to format the disk storage having RAC and ASM

Hello,
Short story:
I need to format the disk storage used by a two nodes RAC with ASM.
How can I have the database working the new disk storage.
Long story:
We decided to change the external disk storage formatting from RAID 5 to RAID 10.
Configuration is: 2 Solaris nodes having Oracle software installed on each node and running with ASM
- node1: ORCL1 database and +ASM1 asm instances
- node2: ORCL2 database and +ASM2 asm instances
Available is a NFS storage with plenty of space.
Please tell me which would be the easiest way to move the database?
Thank you

Thanks alot for your answer.
1) There is more trouble: I also have the Voting disk and the OCR on the same (and only) SAN storage. Do you know about steps to backup/restore and/or recreate these?
As I said I have a NFS file system available with plenty of space.
2) I will need to backup the database, which way would you recommend: RMAN or EXP ?

If the format is NTFS, which it likely is, then follow Ralph's advice, but youmay also want to partition it with GUID partition table.
In Disk Utility, select the drive, then Partiiton tab.
Choose 1-partition from the popup menu.
Click the Options button (it is only enabled if you change the partition layout, above).
Select GUID partition table.
Then, give the drive a Name and format of Mac OS Extended (Journaled).
If you wish to use the drive with Windows, use MSDOS or exFAT. MSDOS will limit files sizes to 2GB. Some think exFAT is flakey.

I can't empty the trash or format the disk on my macmini (2009)

Hi,
I'm hoping someone can help. I deleted some old timemachine backups from my external hard-drive.
Since then I have been unable to empty the trash. I've tried 'trash it!', option>empty trash securely, restarting the computer, the terminal. Nothing has worked and unfortunatley I have no space at all left on my startup disk. I can't rename the files left in the trash either.
Luckily my mac is backed up so I decided to format the disk. When I go into disk utilities and click on erase and select the HD all the fields are faded out i.e. i can't select to erase the disk.
So I repaired the disk, verified the disk & tried again... no joy.
Any ideas would be fantastic!

Okay, I solved the problem so for anyone who has the same issue, this might help:
The reason I couldn't empty the trash was because I had dragged timemachine backup files I no longer needed into the trash, which screwed everything up.
Here's a video on how to delete timemachine backup files properly.
So basically, I solved the problem by formatting the external hard drive in disk utilities through my mac mini.

I have Lion OS but I need to format my disk. How to do it?

Helpppp
I need to format my Mac book Pro
I have the OS Lion and it doesn't let me format the disk!

It is not necessary to create an external boot device.
Restart your computer while holding the option key. After the startup chime you will see your available boot volumes. Choose Recovery HD. (You might be able to start up with command-r to boot directly into the Recovery HD emergency partition, but I have found that only the most recent Macs will respond to this key combination.) Once boot is complete, look under the menu bar's Tools for Disk Utility. Start up Disk Utility, choose your main hard drive partition, and reformat to your heart's content.
You won't be able to perform certain partitioning tasks when booted this way, but you can do nearly everything that you could do if you were booted from an external device or optical disc.

Hello All. I am working on a form, but I need to format the leading in a multi-line text-field.

Hello All. I am working on a form, but I need to format the leading in a multi-line text-field. The options for the text-field only show a font size option, but no other styling options. Is there a way to format the leading? Thanks!

Not within ID, and I'm not sure it can be done in Acrobat afterward either.

I have an imac 2009 the disk drive is damaged and I have lost the passwords I need to reset passwords I tried booting with a macosx disk from an external hard drive but did not read the drive how else can I reset password ?

I have an imac 2009 the disk drive is damaged and I have lost the passwords I need to reset passwords I tried booting with a macosx disk from an external hard drive but did not read the drive how else can I reset password ?
I have a 2012 mac book pro can I use that to connect with firewire and load osx that way? and how woudl I do that?
Thanks so much!

To what password are you referring? Do you mean your user account's admin password? Or do you mean the master password for File Vault or do you mean a Firmware Password?
For an admin password:
Forgot Your Account Password
For Snow Leopard and earlier
     Mac OS X 10.6- If you forget your administrator password
For Lion/Mountain Lion
    Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     When the menubar appears select Terminal from the Utilities menu.
     Enter resetpassword at the prompt and press RETURN. Follow
     instructions in the dialog window that will appear.
     Or see Reset a Mac OS X 10.7 Lion Password and
     OS X Lion- Apple ID can be used to reset your user account password.
If you cannot do the above then try this:
1. Boot to Safe Mode by restarting and after the chime press and hold down the COMMAND-S keys until a black screen with white type appears.
2. At the prompt, type the following commands pressing return after each command line:
     /sbin/fsck -yf
     If you do not receive a "Filesystem OK" message then repeat this command until
     you do. If after seven tries you still do not receive a "Filesystem OK" message,
     then the system is corrupted and needs to be reinstalled.
     mount -uw /
     cd /private/var/db/netinfo
     mv local.nidb local.old
     rm ../.AppleSetupDone
     shutdown -r now
The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.
This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.
How to reset the OS X password without a startup CD:
Reboot into Single-user Mode. Enter the following and press RETURN after each command line
   1. Type fsck -fy
   2. Type mount -uw /
   3. Type passwd <username>
I have never tried this method myself.

My start up disk Macintosh HD is full on my McAir OSX 10.9.4 memory 4GB. I need to clear the disk so that I can update it with the new software IOS 10.9.5 requiring 2.05GB. Need guidance on how to clear space.

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

BootCamp Assistant Error : Your bootable USB drive could not be created. "An error occurred while formatting the disk."

I have a Windows 7 Ultimate .iso file saved onto a "Mac OS Extended (Journal)" formatted USB flash drive. I am trying to install it with BootCamp Assistant and I keep getting the error message : Your bootable USB drive could not be created. "An error occurred while formatting the disk."
I have previously installed Windows 7 on my Mac (and it worked flawlessly - same .iso file), but I uninstalled it because I didn't partition enough space on my hard drive. I have used several flash drive to try and install and none have worked.
Some help would be greatly appreciated.

My mac can't find the volume" Data" on Time Capsule. Also Ican't find with the disk utility program the hard disk in the Time Capule; so I can't format the disk again. What can I do?

My Mac can't find the volume " Data" on Time Capsule, Also I can't find with the disk-utility program the hard disk in the Time Capusule.
So I can't format the disk in the Time Capsule
Deconnevt and then connecting the power tp the Time Capsule gives also no solution.
What can I do?
Joe

I listed the commands.. that is how you manually mount the disk.. follow exactly the commands I gave you.
In finder use top menu, go, connect to server.
Type in the following.
AFP://TCname or AFP://TCIpaddress (obviously you replace with the actual name or the actual IP address).
If that fails..
try
SMB://TCname
Here is the screenshot.
tardis4 being the name of my TC.
It should then ask you for your credentials.
And it should remember them in the keychain and be able to then get TM to connect.

HT201250 I accidentally excluded the disk in time machine and need to bring it back

I got a new hard drive. Time machine wasn't registering it. Realized I needed to install the new External Harddrive software and did. Opened time machine back up and it would never let me choose the new disk (External Hard Drive) so I excluded it from time machine thinking I can "Include" it again to get time machine to register and allow me to choose it. Now Im stuck with a new hard drive and no way to use it. How can I get it back so I can use it!!!!????

It should be in your TC backup. If not, you will need to Reinstall OS X
Note that with Mavericks, you need to go to: /System/Library/CoreServices/Applications/Network Utility.app
(You can drag to your Dock, or make this an alias)

HT1529 I turned on my macbook and it says it needs to recover the disk

I turned on the macbookpro and it says it needs to recover the disk but there is no disk to recover from. How do I repair the disk?

Restart while holding both the Command and R keys, that will start from the recovery hard drive...then go to Utilities and Disk Utility and Repair hard drive. See if that is what it wants you to do.

My Mac keeps starting up to the disk utilities screen. Im guessing i need to repair the disk or load my backed up memory but i am unsure of how to do that. I have all my memory backed up on an external hard drive.

The Disk Utility screen has instructions right on it.
Just read them and follow the directions.
Readers can help if you get stuck.
It opens with something like, "select a disk, volume, or image".
You click on your drive in the left column, top item.
The next screen spells out how to do a ( Repair Disk ).
You have a Macintosh. It will not cut your hand off.
If something dangerous is coming, it will say stuff like, "this will erase all the data on your drive. Do you want to proceed?"

Need help with "The disk you inserted is not readable by this computer."

I have an external disk that I have not used in a while (an older G tech with FW800 ports). Recently I plugged it in and my 2008 iMac (10.8.5) reported, "The disk you inserted is not readable by this computer."
If I leave the external disk in, my iMac won't get past the white screen with the Apple logo on boot up.
With Disk Arbitrator, Disk Utility sees it but reports that it has zero bytes and the Verify and repair disk options are greyed out. DiskWarrior does not see it and if I start Disk Arbitrator up first and then Disk Warrior, everything but the cursor freezes and I have to hold the power button down to restart the computer.
I tried listening to the disk on start up and it makes a fan-like noise and has a slight vibration but I don't think I hear the click-ity click noise of the head reading the drive.
Any tips on trying to salvage its contents?

You may have ordered what you though was exactly the same thing as what you had, but the interface electronics in it are apparently NOT the same, rendering the drive unreadable unless you want to re-partition and re-format it first (wiping all the data in the process).

RAC and ASM with geographically seperated disks

We are planning to use RAC and ASM with four nodes. The two nodes will be at one location and another two nodes at different location. The ASM disks also will be available locally. Is it possible to configure ASM with geographycally serepared disks.
We are thinking of two RAC and ASM setups with two nodes each and streams replication between the RACs.
I want to know what is the best method to implement. Is it RAC with four nodes OR two RACs with two nodes each and streams replication between the RACs.

Apart from the latency issue, which has been mentioned by others, you also need to mirror your disks between the two sites and be very careful about split brain scenarios under node or site crashes.
You need to mirror the disks between the sites in case one site crashes completely and loses all network access. The only way the second site can carry on is if it has access to all the data disks, and the cluster control disks (terms vary for this, such as quorum or voting disk). If you do not mirror you simply do not have a resilient design. Resilience is about eliminating all single points of failures, which means duplicating everything i.e. mirroring.
And mirroring between two remote sites adds more volume to the data traffic between the two sites. And it would need to be synchronous rather than asynchronous to guarantee no data loss. And your commits for each transaction would be limited by the round trip time to write to the remote site and get the acknowledgement back.
Split brain is something you need to avoid with remote clusters, and local clusters too. If the network goes down between the two sites and both sites have local copies of all of the data and cluster control disks, which site becomes the primary and which one becomes the standby? You cannot have both sites coming back up as primary with active databases and accepting transactions! At this point you have split brain, and each side is processing transactions independently, and both databases are now deviating from each other with different data changes.
I don't think a 4 node RAC environment split across geographical distances is really viable, except under small transaction volumes, and where response time (transaction time) is not critical. If you have high volumes and need fast transactions then you need to only use local RAC configurations, and replicate between the two sites asynchronously. DataGuard is easier, but you need to decide if you need Streams and how to make it work for you.
