Cannot see disk in Utility

Hi everyone,
A friend gave me a new external HD, which I reformatted to MS DOS (so Mac & Windows could see it -- was that the right format?). The HD shows up on my Macs when I plug it directly in each of them, but I don't see it showing up when I plug it into the Extreme (via the utility).
I tested one of my other external HD's and could see it fine in the utility. I believe they are both formatted the same too -- any suggestions? Also, any suggestions on the best format option for the external HD?

Create ASM Disk Groups cannot see Disk Path to select during installation

Hello Guys,
I am setting up 2 node RAC on 11gR2 and Linux.
I have configured all the pre-installation steps that are required to run Grid Setup as per my understanding.
I have configure SAN partitions using multipath.
I can see my SAN volume when i query multipath -l
Then i configured the raw partitions by oracleasm. Configured and then created mount points:
/dev/oracleasm/disks/
CRSVOL1 DATAVOL1 FRAVOL1
Later on I created the disks using oracle asm command:
/usr/sbin/oracleasm createdisk CRSVOL1 /dev/mapper/racdbp1 and so on...
I have run /usr/sbin/oracleasm scandisks
Cleaning any stale ASM disks...
Scanning system for ASM disks...
And when i list disk with command /usr/sbin/oracleasm listdisks
it shows the disk like this on both nodes:
CRSVOL1
DATAVOL1
FRAVOL1
BUT during the installation screen when it comes to create ASM Disk Groups It shows nothing in the add disk frame, I cant select the volumes I can list, like i did above.
Any hint please?
Thanks, Imran

Thanks but my problem is very specific. I feel that i have performed all the necessary steps to get complete the step i discussed above. As per different commands all is set. But i am unable to see Disks and Disks Paths during the installation screen. This is another output to verify if the installe user have rights on the asm devices:
[grid@racnode1 mapper]$ cd /dev/oracleasm/disks/
DATAVOL1 ETSCRS1 ETSVOT1 ETSVOT3 FRAVOL1
ETSASM1 ETSCRS2 ETSVOT2 EXTRADM
[grid@racnode1 mapper]$ cd /dev/oracleasm/disks/
[grid@racnode1 disks]$ ls -ltr
total 0
brw-rw---- 1 grid asmadmin 8, 1 Oct 2 16:47 ETSASM1
brw-rw---- 1 grid asmadmin 8, 5 Oct 2 16:47 DATAVOL1
brw-rw---- 1 grid asmadmin 8, 6 Oct 2 16:47 FRAVOL1
brw-rw---- 1 grid asmadmin 8, 7 Oct 2 16:47 ETSVOT1
brw-rw---- 1 grid asmadmin 8, 8 Oct 2 16:47 ETSVOT2
brw-rw---- 1 grid asmadmin 8, 9 Oct 2 16:47 ETSVOT3
brw-rw---- 1 grid asmadmin 8, 10 Oct 2 16:47 ETSCRS1
brw-rw---- 1 grid asmadmin 8, 11 Oct 2 16:47 ETSCRS2
brw-rw---- 1 grid asmadmin 8, 13 Oct 2 16:47 EXTRADM
I will appreciate if you can help me to get through this step... Is there anything else needs to be verified?
Regards, Imran

Cannot see "disks" con in airport utility

I have a MacBook Pro and AirPort Extreme base station(the one that looks like a UFO). I recently bought a 1.5TB Western Digital My Book to connect to the airport extreme. My problem is when I go into the AirPort utility and click manual setup I see the airport, internet, printer, and advanced icons but no 'disks' icon. The software for the airport is up to date because it automatically update when I set the network up as well as the Leopard that I am running on my machine. Also the hard drive has been properly formatted. Any ideas why this is doing this and how to fix it? Thanks!!

Hello kschulz. Welcome to the Apple Discussions!
I have a MacBook Pro and AirPort Extreme base station(the one that looks like a UFO). I recently bought a 1.5TB Western Digital My Book to connect to the airport extreme. My problem is when I go into the AirPort utility and click manual setup I see the airport, internet, printer, and advanced icons but no 'disks' icon.
Sorry, but the earlier 802.11b/g series of AirPort Extremes' USB port does NOT support USB hard drives.

ASM with Oracle10 cannot see disks on Solaris

Hi,
I just installed Oracle10g on Solaris-64 and first thing I tried was to create database using ASM. Seems, ASM cannot find any disks though all 6 of them are available. I tried different ways, but there is no result so far. Any idea what am I doing wrong?
-Dmitri

Ooh, ooh. I did. :)
I had the same problem. Permissions and ownership were set correctly. The path to the disk was set. I could see and touch the disk as the oracle user. But, dbca saw nothing. Connecting to the adm instance and using the gui to create the diskgroup failed to see the disk. After MUCH searching on Oracles sites (otn & metalink) I found this note Create Partitions in Solaris and add them as disks in ASM 271621.1 metalink. It is not really clear way there needs to be 500 MB in slice 0 on a Solaris partition, I tried it at 10MB and found it worked with either slice 4 (the recommendation from the note) or slice 6 (the one that almost everyone working with Solaris [other than this notes author] uses). The size may be much smaller. Oracle must be doing something in slice 0, but I dont know what it is.
Anyway, after partitioning the disk and reserving 10MB in slice 0, the disk did show up in dbca. I am about to reinstall Oracle and try from the beginning.
My next challenge is how do I place the control files and online redo logs on a different diskgroup than the main database. I did not see a way in dbca to manage this.

Format cannot see disks but probe-scsi-all can

Hi Folks,
I have attached a Storedge with five disks to an external SCSI card and can see all the disks via the probe-scsi-all command at the OBP. However when I do a boot -r I would expect to see all the disks with the format utility but I only see the internal disks.
Has anyone had this problem? If so am I missing something obvious?
Thanks in advance.

Hi
check the scsi-initiator-id in printenv on OK prompt .If it is 7 change to 6 and check whether u can see the hard disks through format command. and also u can run these three commands on root prompt to detect the hard disks
1) # drvconfig
2)# disks
3)# devlinks
Best Luck
Regards

Upgrade to 10.4.6 - fail to boot - cannot see disk anymore

G5 20 flat panel with 150 gig hard drive. Running 10.4.5
Downloaded 10.4.6 upgrade and system rebooted. Came up with grey screen, no apple icon. Let it sit for a couple of hours.
Rebooted using install disk. Went into disk utility and my 150 gig drive is no longer there!
Rebooted in single user mode. Attempted to run fsck - nothing.
Rebooted in firewire drive mode. My laptop does not see any hard drive either.
Attempted to perform a re-install - and it does not show any destination drives.
Question: How can I re-establish the presence of the hard drive? Is there a firmware level command set I can use? Terminal commands?
Or am I dead?

When I run re-install, it asks for the drive. Problem is, no drives are shown. It is like I have a bare board with nothing attached.
No matter what I try - disk utility, re-install, single user mode, target mode, DiskWarrior, none of them indicate that there is a drive attached to the motherboard.
Somehow, must re-establish that yes, there really is a hard drive out there.

Cannot see disk in J4200 by "format" command - Solaris 10

Dear all,
I have a Sun SPARC T2000 server and a J4200 array connected to each other by SAS cable. The T2000 server was installer Solaris 10u8.
I installed CAM 6.5 software in my server and I successfully registered the J4200 array, after that, I can see all disks in this array.
However, when I issued the "format" command, I didn't see any disk in my array. I've got the same result after performing a reconfiguration boot.
I do not know how to do now to see the disks in this array.
Please help me in this case.
Thank all of you very much.
HuyNQ.

Folks,
Interesting info as I tried with SPARC base runing Solaris 10 OS. The daemon is auto imported the unit without I have to issue the OS scan device "devfsadm".

Solaris 10 on Newisys 4300 - Cannot see disks.

Dear All,
I am trying to install Solaris 10 on this machine but after going through the initial install screens (indentify host/network setup) it quits the install process complaining that no disks are found.
The machine has an LSI Logic MegaRaid SCSI 320-2 Controller with 4 disks each of which has been initialised.
Fedora Core 3 (64bit) installs no problem on to the machine and sees all 4 disks.
The machine is a dual Opteron with 8Gb RAM. (the Newisys machines are essentially the v20z and v40z machines)
I have tried everywhere to get drivers for Solaris 10 but to no avail. Can anyone suggest where I might get drivers or where I am going worng?
Many Thanks,
Philip.

Dear All,
I am replying to my own message here as I have discovered the problem.
The issue was with the raid card which is the standard card for a Newisys 4300. This is an LSI Logic card for which there are currently no solaris 10 drivers.
In the end we had to buy a raid card from Sun and replace the original LSI Logic card. This now works fine and sees the disks.

AEBS cannot see both disks in 2 disk enclosure set to JBOD

I have a MacPro 3.1 and AEBS, the computer runs 10.6.8 and Win 7. All most recent updates installed on both OSes and the AEBS. I have a generic (bought at Fry's) HORNETTER, 2 disk external USB enclosure containing two (2) 500GB hard drives, both formatted to FAT32 for easy sharing purposes with win, which is connected to the AEBS via its USB port.The enclosure is set to JBOD (Just a Bunch of Disks), so I can see each one individually. The enclosure is externally powered. I have had problems in the past with this set-up off and on. Now it is VERY tempermental, sometimes it works, most times not and now over the last couple months it has stopped working for all intents and purposes.
The problem I get is that the AEBS does not see both drives, only one. This happens in OS x and Win 7.
I get an error saying there is a problem with the disk, connect it to the computer directly and run Disk Utility to check for errors. So I do this every time and it returns no errors. Both disks can be mounted no problem if connected directly to the computer. But if I unplug it from the computer and plug it back into into the AEBS it stops working again.
I have this same problem with my HTPC Mac Mini 2.1 (C2D 2/0Ghz). I tried connection it with the same config and got the same problem, only one disk shows of the two in the enclosure.
Is there anything I could do to resolve this? I have searched high and low for a direct answer, but only see confusing responses and nothing direct on point. I apologize if this is a common issue.
I am not trying to do any Tim Machine backups, just using it one drive to store my media (music, video) and the other drive as a extra storage/share volume/hand backup of important files. I like having it available off the AEBS so I can access the music and video from my HTPC Mac Mini and my DVR Windows machine, as well as using them both as a easy swap for mac files I drop there for when I'm booted into Windows.
Any help would be appreciated.

UPDATE: I read some tips on other related issues, and so I tried connecting a POWERED USB HUB (a Targus brand 4 port AC powered USB hub I had lying around) to the AEBS and then the external enclosure to the hub.
No success, and two different problems.
In OS X I can now SEE both disks (where before only saw one disk), but the problem now is even though I can see both disks I can only access one (the one I could NOT access before). The disk I could access before is not visible but when I try to double click on it to mount it, i get a spinning blue circle and eventually the request times out with an error which makes no sense, but says:
"There was an error connecting to the server “Lou's AirPort Extreme”. Check the server name or IP address, and then try again.
If you are unable to resolve the problem contact your system administrator."
When dismissed this is followed byt eh additional error message:
"The operation can’t be completed because the original item for “BACKUP” can’t be found."
On Win 7, I now cannot see the AEBS at all, and neither disk is visible.
*sigh*
Back to square one......
SECOND UPDATE: Connected a USB thumb drive to the Powered HUB and it shows up fine. So now I am just totally confused.

Moving TM disk from Network to USB: cannot see previous backups

Hi,
I have decided to move my external USB disk from the Airport Extreme USB port to my computer USB port to speed up backups and restores.
Unfortunately it seems that I cannot see anymore previous backups in the disk using TM.
The disk was accessed through the network and it was setup to have user level access to it: each user have his folder on the disk.
So, what I have done is to move back the disk to my computer, I have run disk utility to check and fix the disk since when the drive is attached to the AE with user privileges, it will report errors once you connect back to the computer. Once that permission errors were addressed, I have moved the time machine backup to the disk root and I have told TM to use this new disk as backup location.
Then I have made a new backup to the disk and it seems that TM was able to detect the previous backups because it has added only few GB to the backup.
Then I have moved to a random folder were I have made changes, and I have started TM: when I do that, TM window will switch me back to "MyComputer" where I can see all drives.
I can move around but I am unable to move back in time, like there are no other backups.
TM backup file is about 140 GB and I can fully access it by using finder: I see that all previous data is there, but TM cannot see it.
I have not changed computer name,
I have tried to use the TM option to "open other TM disks" but It doesn't show any other disk in the select window.
Does anybody know what is happening and how I can try to fix?
thanks!

Thanks for the replies,
I would like to move from a wired network TM backup to a local firewire/USB backup.
So the first error I have made is to have deleted the user directory in the Airport Extreme external USB disk: I have moved the TM sparse bundle file to the new location but I didn't noticed that other hidden files were there.
Second, I was unable to browse the older TM backups using TM and it seems that I cannot "browse other TM backups" using such TM option because the window were not showing me any drive.
I have then realized that I have to mount the sparse bundle to see it in such TM option: then it seems to work perfectly.
So there is no need for me to find a solution to use again the same backup with the local disk: if I need something in future I will use the TM option to browse other backups and I think I will be able to recover any file from there. May be I cannot recover mails in this way.
I think it is also possible to fix by using the procedure listed in the previous link: I didn't try just because I don't want to spend more time on this issue and because I have not enough free space on other drives... but...
...it should be enought to:
1- connect a new drive to the computer;
2- mount the old TM sparse bundle image;
3- use SuperDuper to copy all contents of mounted sparse bundle image into the new attached drive;
contents of the sparse bundle image seems to be equal to the structure and names used by a new fresh backup on a local USB disk, so I suppose that it could work... if someone wants to try a tell if it is so... thanks!

I cannot see all the data in target disk mode

I have an issue where my MacBook pro is not booting into the Yosemite. I see the progress bar hangs at about 45% on the startup screen. I called Apple support and they asked to use the target disk mode to connect to my mac and then copy data like that. I am using the same technique but I am not seeing all the data under users. My data under the folder users had another users data that I cannot see.
How can I see my data for all the other users? Help please!!!

Could be that the the data or directors on the HD are corrupted.
- Copy all data you can
- Try cloning the whole disk to another disk before you attempt recovery methods.
- Try repairing the HD via Disk Utility
- Try a data recovery program

Disk Utilty Cannot See HD

I have been getting the 'flashing question mark' folder for a couple of days.
If, when I try and reinstall Tiger, Disk Utility cannot see my hard drive does it mean that my hard drive is dead??
I need to know before I decide on my next course of action.

Andy Moore-
That is why the collective support group is here. We
feel your pain brother!
If you think about it, your hard drive is a
mechanical device that does see a lot of movement
during it's lifetime.
It may be only a computer, but it is such a sweet
computer (;>)
Luck-
-DaddyPaycheck
Thanks DaddyPaycheck. I do feel more cheerful now.
I hate to backtrack, but when I was trying to start the iMac up in Target mode earlier on, I was pretty sure I could hear what sounded like the hard disk's read/write heads clicking.
I don't want any false hope at this stage, but is that anything like a good sign?

Cannot see encrypted disk image in ML

I created an encrypted disk image (password protected folder) through Disk Utility in Snow Leopard. However, now that I have upgraded to Mountain Lion, that folder appears to have vanished or is invisible. All my other file are intact but I just cannot see this encrypted folder anymore.
Anyone else having the same experience or able to offer some pointers?
Thanks,
Peter

There would be no reason for Mountain Lion to hide it. That's not normal behavior. Mountain Lion follows the same rules in this regard that Snow Leopard did. But, you can certainly check to see if it has somehow become accidentally hidden by entering the following command into the Terminal (but don't press return yet):
ls -al
Make sure there's a space at the end, and then drag the folder in which the .dmg file used to reside onto the Terminal window. This will enter the path to that folder in the command. Now switch back to the Terminal and press return. Do you see the .dmg file in the listing? If so, copy and paste the Terminal output into a message here, and I can give you a command that will show that file again.
If it's not there, it must have been accidentally deleted. (Again, not normal behavior, so most likely either it was accidentally deleted by you or someone else who uses that machine or the hard drive is badly corrupt and files are going missing.) Do you have a backup of that file?

I can no longer access my Airport Express Base Station. When I plug it in, it keeps flashing orange. I cannot see it in the Airport Utility.

I can no longer access my Airport Express Base Station. When I plug it in, it keeps flashing orange. I cannot see it in the Airport Utility.
How do I fix this

If you're comfortable resetting all settings, unplug it, hold down the reset button and keep holding it in as you plug it back in - keep holding it for another 10-20s until the amber light flashes
Then, open airport utility, now you should be able to see the device either on-screen or in the upper left under 'other wi-fi devices'

I have upgraded my OS into Mountain Lion and now I cannot see any net storage disks. may someone help me? thanks

I have upgraded my OS into Mountain Lion and now I cannot see any net storage disks. may someone help me? thanks

Hi kiwirudy,
I've had the same problem more than once since I started trying to download my 14 April purchase of OS X Mountain Lion.
I found a property list called manifest.plist in my ~/Library/Application Support/AppStore folder which had a Boolean property called failed checked. I unchecked it and afterwards I was able to resume my download.
Here are some steps I've found useful:
Close the Mac App Store.
make a copy of the ~/Library/Application Support/AppStore folder. For some strange reason the Mac App Store likes to just delete it in some circumstances, which will mean that one has to start one's download again from the very beginning.
Double click on the manifest.plist in one's ~/Library/Application Support/AppStore folder.
This should open it in Property List Editor.
Expand all the nodes (holding down the alt key and clicking on the highest collapsed node should do it.
Find a key called failed of type Boolean and uncheck it.
Save the manifest.plist and close it.
Open the Mac App Store.
The red message "an error has occured" should now be gone and one should be able to resume one's download.
In the event that the ~/Library/Application Support/AppStore folder gets deleted:
start the download again (it will start from the beginning), pause it and close the Mac App Store.
copy your backup copy of the pkg file back to its sub-folder (it's a numbered folder in the ~/Library/Application Support/AppStore folder).
Open the Mac App Store and resume your download.
It should continue from where it left off.
This has worked for me so far. I'm holding my breath. Don't know if I'll still be alive when it's finished.
Regards
Nic
