Can't replace failed disk in RAID1 set

I had disk fail in a mirrored set (2nd disk still works). Disk Utility shows the set as "degraded."
All the documentation says to simply drag the new disk into the existing RAID set and then click "rebuild." However, there is a padlock icon next to my RAID set and no changes can be made. All options are grayed out and dragging the new disk into the set is simply ignored.
I guess I am dumb because I can't figure out any way to unlock the set, and numerous searches here on the support site have yielded no solutions.
Help?

I believe you must first "remove" the failed drive from the computer and install the new one. It must be prepped for use:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
I believe then you can "add" the new drive back to the original RAID set and rebuild the RAID.

Replacing failed disk on hardware Raid 1 mirror

Hello all,
I have an old T2000 Server with a hardware Raid1 mirror. The secondary disk failed and I purchased a new one. Its hot swap so I plugged it in and when I do a #radctl command it shows that it is in SYNC status but it never gets back to optimal. I am unfamiliar with this process. What needs to be done to get the new disk to be synced properly? I waited hours to see if it would succeed but never did. Any help is greatly appreciated.
Thank You

It may take several hours depending on system activity and on disk size.

Transferred activation, before replacing Failing Disk,

we had to use a tombstone backup to prevent corruption from propogating to new Disk
the problem is the only good backup image available had an activated install of both AA2 and AA3
the last time I had to do that was on another system
and I was presented with a "repair activation" window
now on this system I get a full activation window for both AA2 and AA3 which doesn't function on either
normally when I change a disk
I transfer the activations first
then take the image and restore to the new disk the unactivated product
this normally works
but we had no choice in this matter as the disk was just about fried
would uninstalling and reinstalling allow the activations to proceed?

"the activation process doesn't just look at the disk but the motherboard too... and it's sneaky"
in most instances this would be considered a ROOTKIT
Un-install - Re-install doesn't work
I didn't change the MB
I didn't change the processors
I didn't change the video card
I didn't change the NIC
I didn't change the sound card
I didn't change the OS
only the FRIED HDD
at my home Office I use Symantec Backup Exec
at the company Office Acronis is used
a full restore at my house to another disk gives a "repair activation" window
a full restore to the same disk gives no change in activation status
a full restore to the same disk at the company office gives no change in activation status
a full restore to a replacement disk doesn't give the repair activation window
rather gives the following
"activation information is invalid"
(which occurs when launching previously installed product recovered from backup image)
then after uninstall re-install sequence
"yer 30 days is up"
and the following dialog is presented when attempting activation in either case of new HDD
here's the dialog I get when trying to activate after restore to new disk
before uninstall and after uninstall - reinstall procedure:
internet connection not detected is a lie because I just posted this from the system in question

Replacing a failed disk (SATA drive) on UCCX (MSC-7825)

Hi,
I discovered a failed disk drive on the UCCX server (non-HA mode). Now, my task is to get this disk replaced. What are the typical steps to follow and what precautions should I take care besides backing up the config data)? Since thsi would be my first time doing this, I was hoping for some detailed steps to follow while doing this replacement.
The Model we have is the MCS-7825 -H4 CCX - premium. I have received the HD form HP.
I have found only data sheets on the cisco portal & hence was wondering if there is any other guide that can walk me through the steps.
Thanks,

This is pretty standard hardware "stuff".
I suppose the SATA drives are configured in a RAID1+0 array through HP's Smart Array controller. You can open the HP Smart Array tool in Windows and ask it to show you the status. If it indicates the drive has failed, it will help you replace it and mirror up while the box is running.
This is a little scary if you have never done it, so I appreciate your caution.
The best thing to do is to try this on your lab machine. There is NO substitute for experience at this level.

Geoff

How can i made a snapshot of a disk and replace the disk on another server solaris 11?

Helo! I am trying to replace a disk on my solaris 11 with a snapshot of another server. I did the snapshot, but how can i send it to another server? I have try somethings, but It didnt work. Look:
#first tentative
zfs send /rpool/vdisk/srvdth05-ldom1.hdd0@snap1 | ssh 192.168.4.52 zfs recv /rpool/vdisk/'srvdth05-ldom1.hdd0'
cannot open '/rpool/vdisk/srvdth05-ldom1.hdd0': invalid dataset name
#second tentative
root@srvdth03 # scp [email protected]:/rpool/vdisk/srvdth05-ldom1.hdd0@snap1 .
Password:
scp: /rpool/vdisk/srvdth05-ldom1.hdd0@snap1: No such file or directory
#third tentative
zfs send -i rpool/vdisk/srvdth05-ldom1.hdd0@snap1 | ssh 192.168.4.52 zfs recv "/rpool/vdisk/snaps"
cannot receive: failed to read from stream
#fourth tentative
zfs send -Rv rpool/vdisk/srvdth05-ldom1.hdd0@snap1 > /rpool/snaps/vdisk-hdd0.snap2
scp [email protected]:/rpool/snaps/vdisk-hdd0.snap2 .
in the other host
zfs receive -r rpool/vdisk/vdisk-hdd0@snap < /rpool/snaps/vdisk-hdd0.snap2
cannot receive: can not specify snapshot name for multi-snapshot stream
I dont know what to try anymore. Someone can help me please?

Hi.
This form is correct :
zfs send rpool/vdisk/srvdth05-ldom1.hdd0@snap1 | ssh 192.168.4.52 zfs receive rpool/vdisk/'srvdth05-ldom1.hdd0
Dataset name do not content first "/" at starting name.
You can check what datasets available with command:
zfs list
On system 192.168.4.52 you should preparare dataset.
ssh 192.168.4.52
zfs list | grep rpool
zfs create -o mountpoint=none rpool/vdisk
in case dataset rpool/vdisk/'srvdth05-ldom1.hdd0 on 192.168.4.52 olready present, you need add "-u" for recv
Read manual about zfs command for section send and recieve.
man zfs

Nik.

Replacing a failed disk in storage space ! unable to remove a retired disk

Hi Folks
Not really asking for much !! we are using windows 2012 R2 storage space ; one disk failed
and marked as retired.
today we received replacement disk ; added that to storage pool - fine.
then I repaired all Virtual Disk - process was very quick and went to 100% like a flash.
then I tried to remove faulty disk by using following commands :
$DeadDisk=Get-PhysicalDisk -FriendlyName PhysicalDisk-1
FriendlyName CanPool OperationalStatus HealthStatus Usage
Size
PhysicalDisk-1 False Lost Communication Warning Retired 185.5
GB
Remove-PhysicalDisk -PhysicalDisks $deaddisk -StoragePoolFriendlyName storagePool
this errored out ; basically saying that the above disk is still in-use !
Any suggestions ? does repair job take some time ? it looked very fast ; when I did get-storagejob ; it showed 100 percent completed .

Hi,
Please reboot the server then set the failed disk to "Retired" and remove the retired physical disk.
You could refer to the thread below to troubleshoot the issue:

never had this before download of Mountain Lion.

As others have stated, this is a potentially catastrophic event. Consider yourself lucky, as hard drives usually just fail wihtout warning. Your disk could die at any time. This is a mechanical / physical failure, not software related.
Going forward, I would suggest utilizing a utility that monitors SMART status, which you obviously don't have, such as SpeedTools.

RAID1 set shows Apple_HFS partition, although disks had GUID partition

I am trying to build a RAID1 set for backup purposes from 2 external disks (Firewire connected). Disk 1 has one partition with GUID. Disk 2 has 2 partitions with GUID, number 1 of these partitions with the same size as disk 1 is used for the RAID set. When I build the RAID set with Disk Utility, the set gets Apple_HFS partition, and the 2 volumes have partition type "Apple_RAID". The set cannot be used as a bootable disk for an Intel Machine. Is this a bug?

The Intel® Mac uses a different hard disk format scheme than the
PowerPC Mac. Reformatting to GUID is said to work with FireWire
drives, and not necessarily as good with some USB 2.0 units.
TMO Quick Tip - Format a Drive to Boot Intel Macs:
http://www.macobserver.com/tip/2006/08/16.1.shtml
The Apple Partition Map and HFS+ have certain limitations in an
Intel® Mac configuration where an external hard disk drive is set
to boot and run a computer from a viable clone or backup scheme.
Since I don't do all that fancy stuff, I am not experienced enough
to further comment; mine use CCC to HFS+ formatted FW HDD
and I make manual clones of my entire computers to partitions;
bootable copies of everything, when I get around to doing it!
Good luck & happy computing!

I recently got a new iPad from Apple, everything was stored to the cloud now I have set up new iPad i have nothing. Apps can b replaced pics cannot. Can anyone help me please?

Sorry to read about this. A relative had a similar experience. Just a few things she was told to do. Hopefully one will get your content back. Make sure you are logged in to the same Apple Account the last iPad was. You should have a recent backup that can be downloaded to have your new iPad look like the one you replaced. When I changed from one iPad to another I used my last backup and all my apps and photos reloaded with no issues. This was done over wifi.
Another way is connecting your iPad to a computer that is logged into your iTunes account. It will show what backups you have available to download To your iPad. Again hopefully a recent backup was made of your iPad with all your most recent content.
In my cloud settings I made sure any photos I took were uploaded to the cloud to be downloaded automatically to my iPhone and visa versa.
If you had your photos setup to be uploaded to the cloud they should still be there. You just need to be logged into your Apple ID and your new iPad and I see no reason you cannot access them. Hopefully it is a simple fix.
good luck. Jeff

Soundbooth (CS5) fails to load a set of .aif files (that other programs can happily open)

Soundbooth is failing to open a set of .aif files, has anyone had a similar problem? I have tried loading these .aif files in other programs, but every program in CS5 fails to open them.
Does anyone know why this is happening, have any similar experiences or know if and when this is going to be resolved?
Considering I paid for this I am very disappointed that I've been having so much troubles loading aif and wave files that so many other programs open without any issues - and I've not heard a word in response to my actual problem that I have been reporting on for a few months now.

ADDENDUM:-
When I say "I have tried loading these .aif files in other programs", I mean outside of CS5, and they open the files without any trouble.

Disk utility false "failed" disk errors

Hello, I'm really hoping someone can help me solve this problem.
I have an iMac (see specs below) connected via Thunderbolt to a LaCie 2big RAID drive (with two 3TB internal Seagate drives set up as mirrored RAID slices). Both the iMac and the LaCie drive were purchased brand new in 2012 and worked flawlessly until April 2014. In April, one of the LaCie's two internal drives failed and could not be rescued using Apple's Disk Utility. Since the LaCie unit was still under warranty, LaCie replaced the affected internal drive at no cost. Since then however, Apple's Disk Utility has been giving me a "failed" disk warning on the same internal drive about once a month. The first time, LaCie simply directed me to reformat the drive and the problem went away. But the same problem has appeared roughly every month since then.
I sent the entire unit back to LaCie for diagnosis and they told me that the drive is perfectly fine. In other words, it's a software failure, not a hardware failure. I was told that Disk Utility was giving me false errors, possibly caused by the iMac going into sleep mode and not ejecting the disk properly. They said they've seen it before, but Apple has not yet released a patch for it. Since receiving the drive back from LaCie, I've changed the iMac's energy saver settings to prevent it from going to sleep after any inactivity. However, the same drive failed again this morning.
The only solution LaCie has given me is to wait for Apple to release a patch and in the meantime, reformat my drive whenever the "failed" warning appears to clear the problem. However, I have more than 2TB of data on this drive and the process of backing it up, reformatting the disk and copying all of my data back again typically takes more than 20 hours. I simply cannot afford to keep doing this every month. LaCie seems to have washed their hands of this and pointed their finger at Apple's Disk Utility. My questions is, has anyone else had similar problems? And if so, what is the solution?
Hardware Specs:
27-inch iMac, Mid 2011 (3.1 Ghz Intel Core i5, 12 GB RAM)

Thanks,
Mike.

Permissions you can ignore on 10.5 and 10.6:
http://support.apple.com/kb/TS1448?viewlocale=en_US
Using 'should be -rw-r--r-- , they are lrw-r--r--' as an example, you will see the that the permissions are not changed, but the | indicates a different location. This is because an update to Leopard changed the location of a number of system components.
As long as you see, "Permissions Repair Complete" when it's finished... you're done.

Open it up. Buy a new replacement drive. Install Mac OS. Then give it to them if you still have trouble.
As for the install failing,
I never do the older "archive and install"
I format and initialize first, even zero the drive, and only then install.
of course all the data is lost.
Data Rescue 3 demo can scan a drive but you need to have setup a 2nd boot drive to work from, AND you would need part of that 2nd drive partition for recovery of data. 30-50GB system partition and 150% the size of the drive you want to recover.
TimeMachine I never adopted or liked but 350% and would only use as secondary backup with cloned copy of your drive.
Backups can be scheduled, run at night or weekend or both, a weekly clone and daily sets.
Disk Warrior 4.2+ is another $100 (DR3 is about same but demo is free to try).
A spare external drive case $30? and TWO hard drives, a replacement and backup/recovery $100 each?
Just some ideas to throw out there....
Bootable clones though you will find are very useful, handy.
I like the small 40GB emergency boot partition - put one on your TimeMachine drive etc.
LION: the one good thinig: it has a recovery mode partition and new Macs have "net install" feature and minimal hardware diagnostic over the internet to do Apple Hardware Test. Lion $30 and might actually want to install it on external.
So DO try installing OS X on one of your external drives - create 40GB volume just for that - if you can please.

Directory Damage, what can be used for Disk Repair and Virus Detection?

Hi,
My eMac is acting up. Yesterday I started getting these messages that I needed to restart my computer (message was in a brown box window with an icon of a start up button in background).
I did the disk repair using Start up CD and it came back with "invalid key......." or something like that, and when I tried to repair it, it tried to repair the B-Tree's but then said it could not repair the problem.
I have Diskwarrior 3.03 Build 39, on a CD and on my FW Ext HD, which has a clone of my Mac HD.
Diskwarrior could not produce a graph of Mac HD because the directory was damaged. When I did a rebuild it hung on step 9 comparing directories, said there was 7 million + tests. ( I let it hang on step 9 for 15 hrs. to see if maybe it was just taking a long time due to corrupt directory). I finally clicked on Skip and got to the report page. I could do a preview, but the replace button is greyed out. When I was comparing the sizes of each folder, in both preview and original, I got a can not calculate error message on a few of them. The size of Mac HD in preview compared to the one in Original was different by 4 gbs. A week ago I repaired the Mac HD and did a Diskwarrior directory repair on all my HD's.
Before I do any reformatting of HD or other drastic measures, I was wondering what is safe to use for disk repair and virus detection. I know there is Norton System Works 3.0, Norton AntiVirus and TechTool, are these the only ones? Are these safe to use? Are there any other programs that can repair directory damage?
Thank you in advance,
Deb

The long-standing rule of thimb has been that if Disk Warrior can't repair a mungled disk directory, then you're looking at reformatting or replacing the hard drive. Since this is a week-old hard drive, I'd suspect the replacement hard drive is itself bad. It might save you grief in the long run to contact the vendor who sold you the drive and inquire about their warrenty. You might want to first run the file system check utility fsck as described in Using Disk Utility and fsck
Directory repair and antivirus protection are different critters. Norton AV is mostly safe (if you don't mind it's track record of false positives) and is used by the IT department at the lab where I work. Norton SystemWorks, AKA Disk Doctor Kervorkian, is most assuredly NOT safe. For every poster reporting something nice about it, you'll find at least 2 dozen cursing it. It has a known track record of detecting problems no other utility finds and of "repairing" drives such that nothing can then read or repair the drive short of low-level reformatting (and occasionally even that fails).
Tech Tool Pro 4 has a good reputation, as does Drive Genius. Tiger OS X 10.4.2 and later include a version of Disk Utility that can for the first time also make effective B-tree and keys out of order and overlapped extent repairs. Still, my personal gut feeling is that if Disk Warrior is choking on the hard drive, you're looking at reformatring while zeros the drive (zeroing should detect and map out bad physical secotrs).
You can also refer to Disk First Aid: What to do when it finds an error and to Handling "overlapped extent allocation" errors reported by Disk Utility or fsck

I I have a late 2005 power PC G5 that I want to bring back to life. I need to replace the original hard drive, a Maxtor 250 GB Sata. Can I replace it with modern drives, SATA 5-6 etc?

I have a late 2005 power PC G5 that I want to bring back to life. I need to replace the original hard drive, a Maxtor 250 GB Sata. Can I replace it with modern drives, SATA 5-6 etc?

I knew I should never get rid of my old G5's. By the way, there is a browser still supported for the PPC, TenFourFox, if you're not using it already. Go to the Floodgap website (they author it) download it for free. The only thing it doesn't support is the Flash plugin, but the browser works great. Other video types are supported. It's based on Firefox, and runs most of the plugins and add-ons. It's very fast, and beats all other browsers on the browser compatibility and speed test. That's now my default on my G5's. Firefox and Safari are no longer supported. As far as the OS, both Tiger and Leopard were solid for me. The reason, as I stated before, was iMovie. The version in Tiger with iLife was far superior to what Apple changed it to. They 'dumbed it down' for the masses. Even the newest iLife 11 on my Mac Pro quad isn't is good, in my opinion. So Leopard should be fine for you. It's a much larger browser in terms of sheer megabytes and disk space, but it's fine. As far as getting an OS disc, I'm seeing Tiger for about $45.00, Leopard for $50 - 60.00 on that famous auction site. As far as RAM, I have 8GB in my G5 2.3, but you should check Activity Monitor when you are running your apps. See how much green slice you have left (unused RAM). You might find you don't need eight. A Mac Pro will grab more free RAM than a PPC machine will. I have a hard time maxing out use of my 8 on the PPC. Not true with the eight on my Mac Pro. The OS doesn't hesitate to grab and use it. You might be OK with 6GB on your PPC. More will not make you faster, as long as you still have free RAM available. As far as backup on your resurrected machine: look for a firewire enabled backup if can. Use CCC (Carbon Copy Cloner) and make a clone backup. Next time your PPC machine wipes out the hard drive, just take your Firewire drive and plug it into another PPC machine, and you can select it as your boot drive. You'll be back and running in five minutes. You can also take the physical drive out of your enclosure, and put it in your tower to replace the failed drive, and you'll be back to where you were in less than ten minutes, OS and all. The PowerMac has an 800 port, so you can do the 800 on the machine to an 800 port on your backup. A firewire 800 to 800 cable is only about $8.00. It runs nice and fast through the 800 port. I like the OWC Mercury Extreme enclosures. They use USB, Firewire 800, and eSATA, so all your options are open.
