Bringing an internal drive back online without rebooting?

I currently have (4) internal 1TB drives, (3) of which are backed up via Time Machine (NAS connected via iSCSI). I'm in the process of adding a large external Raid-5 array and plan to use it in place of the internal drive w/o backup. This frees up one internal drive. I was thinking of using this as a bootable backup, cloned from the main boot drive with SuperDuper. When the computer first boots up, this boot drive clone is available in case the main boot drive fails. Once running, I want to take the clone drive off line to maximize it's life, reduce the heat load, etc. Problem is, how do I bring the clone drive back online for nightly SuperDuper cloning without rebooting?

NAS connected via iSCSI
Umm, if it's iSCSI, it isn't NAS, but that's beside the point.
how do I bring the clone drive back online for nightly SuperDuper cloning without rebooting
via either Disk Utility.app, or the command line equivalent diskutil
$ diskutil mount
Disk Utility Tool
Usage: diskutil mount \[readOnly\] MountPoint|DiskIdentifier|DeviceNode
diskutil mountDisk MountPoint|DiskIdentifier|DeviceNode
diskutil u[n]mount \[force\] MountPoint|DiskIdentifier|DeviceNode
diskutil u[n]mountDisk \[force\] MountPoint|DiskIdentifier|DeviceNode
diskutil eject MountPoint|DiskIdentifier|DeviceNode
Mount, unmount or eject local disks or volumes.
Unmount also works on network volumes.
MountDisk and unmountDisk will operate on all partitions of that disk.
Example: diskutil unmount /Volumes/SomeDisk

Bringing a Physical Standby database online without (a) tablespace(s)

Dear all,
Is it possible to create a kind of "dblink" in a physical standby database residing in a remote host (another host than the primary production database)? We want to make this standby DB to be online without one tablespace.
Our database consists of 2 parts: a core part (around 55 Gb) - stored in 2 tablespaces, residing in one mounted disk - and an "attachment" part (around 550 Gb) - stored in one tablespace, residing in 2 mounted disks. The attachment part is of less importance. We would like to make a standby DB for the core part and exclude the attachment part (because of its extensive size) to be online.
Currently we can not put this physical standby DB online, since it requires the attachment datafiles to be available.
Would it be a problem if we NFS mount these 2 disks on the host where the standby database resides?
The best solution would be if we can tell the standby DB that there is no need to update the attachment tablespace.
Thanx a lot for anyone reading, thinking and most of all give the solution for my problem...
Agape
Thanx in advance.

Hi Sybrand,
Since we only will use the standby DB in read only mode, maybe the use of a Logical one will be usefull afterall.
Can you please explain how to configure this need (having a standby DB without this one large TB) in a Logical standby DB?
Your help will be highly appreciated.
Thanx

Moving offline media back online

I have PSE 4.0, on an HP running Windows XP. My question is, I have a lot of photos stored offline on CDs that are already linked in my catalog (I originally used PSE to move them offline). Is there any way I can bring these files back online without opening each one in the editor?
Thanks!

Heather,
Do you by any chance have the "Organize Your Photos with Adobe Photoshop Elements 3" book by Michael Slater? It does apply to your version 4 also.
I think that page 37 of that book has the information you want -
"If you want to later convert offline photos to online by copying them to the hard disk, use the Move Files function"
If you have the book, there is more information on pages 61-62 about the Organizer File > Move command. If you don't have the book, I suggest that you look in the PSE 4 Help.
Then I would choose a few insignificant photo files to check your results before moving larger groups of photos.

If I close Firefox, I can't open it again without rebooting. It says that Firefox is still running.

I have Firefox 6.0.1. I am running it on a desktop with Windows XP. I have always loved it and need it for one program I use a lot. Lately, if I close Firefox for any reason, I can't open it back up without rebooting. It says Firefox is still running. I have deleted Firefox and reinstalled it several times with the same result.

2 Internal Drives 2 External Drives

I have two internal drives that I would like to backup to two external drives. I love Time Machine and have been using it to backup my primary (startup) internal drive to one of the externals. Now I'd like to backup the other internal to the other external drive, but I don't see a way to do this with Time Machine. Really don't want to go back to using Retrospect. Any ideas?
To clarify:
Drive A, my main internal drive, backs up to Drive B, an external drive, via Time Machine. I want to use Time Machine to backup Drive C, my secondary internal drive, to Drive D, another external drive.

i have been looking for same answers, but i think depending on your usage you CAN do what you need, only you need to look at it with less user control - i.e. specifically being able to back up ONLY A to B and ONLY C to D.
what you can do though is, You can 'join' drive B and D as concatenated under disk utils. so for example if A, B, C, D, are all 250Gb drives, you join B&D to become a single 500Gb concatenated disk set called "BD", and set time machine to use "BD" as it's disk. then select both drives A & C (your two internal drives) to be 'backed up' using time machine.
assuming all goes well, you'll rarely need to call on time machine anyway. If A or C have a problem, you will be able to source the files from the externals using time machine as normal and if neccessary, replace A or C and get back up and running from "BD".
and if B or D fail at any point, they were only the 'back-up' anyway. and same issue is there for all TM users.
so all would be as apple intended, with the possible exception of size / storage / usage issues, IF your external drives are same size or smaller than the internals. Apple suggest 2.5x the storage for TM back-ups, but i think that assumes heavy disk usage, large files and never invoking any (too long ago to back up) problems using TM. but even same size drives offers at least daily back ups and even more assuming you don't run your internal drives at more than 75% capacity?
you could even take a Clone of your Boot drive using something such as CCC or Super Duper once a month or whatever suits (using a separate or smaller/cheaper external) then exclude a whole bunch of big files that don't change often (such as applications folder) from taking up space on "BD" / time machine.
anyway, i think i've talked myself into it, and i'm off to fettle with my huge array of currently wasted disk space!
p.s. if anyone running into this thread knows what happens if Concatenated disks fail. i.e. "can you extract data from one disk if the other dies?" might be handy to know...

when i say 'daily' i mean, if TM is set to back up daily, you may use you entire TM space each day, and only every be abel to go 'back in time' by one day. it's a recent and reliable back up none the less.

I have a 2009 MacBook Pro. How do I do a backup on the new internal hard drive using my existing LaCie external drive without re backing up the entire internal drive. Just want to backup most recent changes

I have a mid 2009 15" MacBook Pro. The existing internal drive was about to fail so I had it replaced with a 500GB western digital drive. I have been backing up my system with a LaCie 500GB external drive. I want to perform a new backup using Time Machine but I only want to backup any changes from the last 30 days or so. I want to avoid doing a total system backup thus duplicating most of the data on my external drive and pretty much filling it up. Any suggestions appreciated

Look at this web site devoted to Time Machine:

I suspect that this portion will address your situation:

Backing up images on external hard drive and restoring to new internal driv

I recently purchased a new external hard drive and a new internal hard drive. Before installing the new internal drive, I backed up the old internal drive on the external drive. Then I installed the new internal drive to my Macbook Pro. However, when I tried to access and print my Aperture images on the new internal drive, I received an error message saying "versions with unavailable master images cannot be printed." I clicked on 'show referenced files," but couldn't determine how to recover my master images. I checked the forum and under "referenced files go offline after restore from a backup" it said to go to "File>manage referenced files" but nothing else. How can I recover my master images? Please help - I have nearly 6000 images that are lost without recovering the master images. And no, I was ultra stupid in not placing everything in a vault = but I'm relatively new to Mac OS and thought a backup would be sufficient. Thank!

The volume name of the new hard drive needs to be the same as the old hard drive - rename it if you have to - then they should be fine.
If you cannot seem to make this work then you will have to reconnect them with locate referenced files under the file menu. Select all the files that are disconnected before going into the dialog.

How to bring a disk back online on a T3B system

Storedge T3 firmware 3.2.3
Hello,
I have a disk that appears as offline (fru stat), I have reseat, rebooted the T3B but it stays offline (the disk's LED is green).
I've checked the documentation, googled for it, but I can't find a way to bring the disk back online.
Any ideas?
cheers,
G.

If the enable does not work, another trick is to pull the disk, wait for a few minutes until you get the warning message about the 30 minute time frame, then do a couple of fru stats and then put the disk back into the array.
Assuming the disk is part of a volume, what do you get from vol stat and that particular disk? If you are using disk 9 as the hot spare, has it taken over the offline disk as part of the volume?
Cheers
Stephen

HT3275 My Time Capsule has been backing up without any problems and all of a sudden it stops reading on my computer. The external hard drive beeps three times and the motter wont run within. What happened?

My Time Capsule has been backing up without any problems and all of a sudden it stops reading on my computer. The external hard drive beeps three times and the motter wont run within. The light that usually blinks while in use is no longer blinking and is on constant. What happened?

Sorry we are unclear as to the external hard drive and its connection to the TC..
For instance the light that blinks.. is that the TC or external hard disk or what.
Did you try just rebooting / restart the whole network in correct order.. modem.. router / TC.. external drive.. clients with 2min gap between each.
Are you actually running Snow Leopard as the profile states?
How old is the TC?

Can the iMac G5 be used without an internal drive?

I bought a used iMac G5 1.9GHz as a second computer for my wife. It was a steal but it also came with some issues. After spending a few days trying to install the OS without any luck I'm not sure what my options are. The Apple Hardware Test that comes on Tiger reports a Mass Storage Error. I've gotten 2 different ones with 2 different hardrives: 2STF/4/3: S-ATA Bus 0 - Master and 2STF/8/3: S-ATA Bus 0 - Master. However when I put both hardrives in a USB box and test them on my other mac, they both come out clean and error free.
While trying to install Leopard I get a little ways and then get a Kernel Panic - "You must restart your computer..." I'm suspecting the issue might be the HDD controller.
Can this computer be run without an internal HDD and only a firewire one? I was thinking of just removing the internal drive altogether and buying a firewire box. Is this possible?

I opened it up for umpteenth time, unplugged the hardrive and it started beautifully. I think (visualize me typing with my fingers crossed) I've solved ALL my other problems as well. It no longer gives me kernal panic errors, firewire works consistently and I finally managed to get the OS installed.
I'm actually thinking that I can install a drive in there with a small firewire controller board I have (there is room for in up in the top corner). Take the SATA power cable, change the plug on it and wire it into the IDE drive and firewire controller then run a short fw cable through the bottom of the case, around the back and just plug it into the fw in the back. Then I wouldn't need to purchase a fw case.
Thanks for all the help.

Internal hd down, replaced with external, two weeks later I rebooted and internal is back up!!

I don't know if this has happened to anyone else, but after using a late 2006 20" iMac for the last 5 1/2 yrs. it decided to give me a folder with a question mark in the middle of the screen when I tried rebooting a few weeks ago. After reading multiple forums and tech support advice, I learned that my hard drive bit the dust. That's what the question mark meant, it was nowhere to be found. I decided to get a new 3.5" SATA hd. (A friend of mine just happened to have one unopened!! What luck!!) Instead of going through the hassle of tearing my mac apart, I just bought me an enclosure shell and plugged it in. I did a recovery off of my Time Machine backup and now I'm back in business. Here is the strange thing... I shut down my mac and went to church. When I got home I started it up and my internal drive happen to start working again. The only thing I could figure is that maybe it got too hot or something. Now I have two hd's, internal and externa, (plus my Time Machine backup)l. This seems to be presenting a problem with Time Machine. Does anyone have any advice as to what I could do as far as the internal drive is concerned? I hate to use it as my main drive and have it crash on me again. And can Time Machine backup two hard drives at the same time? I've been wondering about using RAID but am not that familiar with it. What's the difference between concatenated RAID and striped RAID? Any advice would be appreciated.
Oh, BTW, I am using Lion as my operating system. I know they said it wouldn't work on anything before 2007, but it has been working since July of 2011.

I am migrating to a new iMac via TimeMachine back up. My iPhoto libraries are on external drive. I'd like to migrate only the internal hard drive data to the new internal Drive then just plug in iPhoto library drive. Is this going be a problem?

I am migrating to a new iMac via TimeMachine back up. My iPhoto libraries are on an external drive. Both drives are backed up on Time Machine. I'd like to migrate only the old internal hard drive data to the new internal Drive and then just plug in iPhoto library drive to the new iMac. This would save having to transfer several hundred GBs of data. Will this work using Set Up Assistant?

Your user account on the new Mac must have a different UID than on the old one. See the pink box in Problems after using Migration Assistant for an explanation.
You'll need to change the permissions on the iPhoto library on the external HD. Do a Get Info on it, click the padlock at the bottom of the Sharing & Permissions section of the Info window and enter your Admin password.
Then click the plus sign, select the user account you want on the next screen, and click Select. Then change Read only to Read & Write for that user via the little arrows. Finally, click the "gear" icon and select Apply to enclosed items. That may take a few mintutes on a large library.

Time Machine won't back up to internal Drive through AFP?

Hi All!
Heres my Problem.
I have a Mac Pro system with 4 Hard Drives installed inside the internal Bays. I wish to use one for Time Machine for the Clients.
On the clients i get the error about it not having the correct AFP version. (I know this is a common problem within Lion).
Although surely if the hard drive is inside a Mac Pro Server running Lion then the client should be able to back up through it to its INTERNAL drive.
Or does this still count as NAS?
Thoughts?
Dan

We are going to need more information from you in order to help.
What kind of hard drive is this?
How is it formatted?
Where is it connected? Directly to your Mac?
How is it connected? USB? Firewire?
What have you tried so far?
What error messages have you received?

Paragon even has non-destriuctive conversion utility if you do want to change drive.
Hard to imagine using 3TB that isn't NTFS. Mac uses GPT for default partition type as well as HFS+
