ASM not mounting after reboot of external storage

I have a setup with 4 internal drives and 12 external drives(external storage, multipath). The diskgroup was orignally created on the 4 internal drives and then the disk group altered to add the external storage. Everything was fine until the external storage array got powered down. Then we rebooted both boxes and ASM did not come up. I also see the HEADER_STATUS as UNKNOWN for all the external storage drives.

Hi,
Verify if oracle software has read write privileges on raw devices, cause some Operating Systems changes owner to root after reboot the servers.

Ssd not mounted after reboot (mbp mid 2010)

I Have a question regarding an issue with my macbook pro mid 2010.
I Just reached home and opened my macbook and decided to restart it after a days work (normally i put it to sleep by closing the lid).
to my suprise, it won't boot anymore. First a grey screen with a prohibited sign, then after rebooting again the recovery is launched. When I check disk utility the SSD is recognized, but appears not mounted and renamed to disks2. I checked the sata connectors, which appeared to be fine.
macbook got 8gb ram; ssd=500 evo, which I installed about a monh ago without any problems. Clean installed yosemite last week.
Anyone an idea what is wrong and what can be done?

It would appear that the SSD is faulty. Replace it with another one.
Ciao.

RAC does not start after trying to move storage

Hello,
We have a two nodes RAC Oracle 10g and ASM groups defined on one external storage.
RAC does not start after we reformated the storage to RAID 10.

1) deleted the database
2) reformated the external storage to RAID 10 and defined needed volumes for OCR, VotingDisk and ASM
3) on both nodes

Problem is that the RAC is not healty, I know how to start it but now it doesn't start and I cannot find helpful logs.
You can see that cluster is not healty from cluvfy output.

My Airport Extreme and Time Capsule both cannot do not mount my Seagate USB external hard.

My Airport Extreme and Time Capsule both cannot do not mount my Seagate USB external hard.
I am running OS 10.7.5
Both the TC and AE are updated to 7.6.1
The Seagate drive in formatted: Journaled HFS+
I tried everything on Apple's Article: HT1331 and the basic reboots and restarts.
"Next"

It sounds like you may be confusing "mount" with "recognize".
Connect the drive to the USB port on the AirPort Extreme
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Extreme icon, then click Edit
Click the Disks tab
Does the AirPort Extreme "recognize" your hard drive? If yes, it will be displayed in the window.
See example below of a WD 500 GB drive connected to the AirPort Extreme.
If your drive is formatted HFS+ and it does not appear here, then you will almost certainly need to use a powered USB hub with the hard drive.....even if the hard drive has its own power supply. The USB port on the AirPort Extreme and Time Capsule is under powered.
Post back when the drive is "recognized" and we will next "mount" the drive.....although you likely already know how to do this.

Time Capsule not mounting after Restart

I have only used Time Capsule for 2 days. However, it does not mount after Restart. I have to manually go in to the Time Machine Preferences and choose it again as the backup disk. Is anyone else having this issue, or is that the way it is supposed to work? Please help.

I can see where you're coming from. I have just invested in an iMac with iLife08 , iWork08 and .Mac
I saw getting this Time Capsule as the logical last step in this splurge.
I still have an old Dell desktop WIN 95 vintage which is still chugging along, VERY slowly, its specs having been increased way beyond what its makers ever planned.
I think (hope) this Time Capsule saga is a bit of a blip, superimposed on software (Time Machine) which has not been fully ironed out yet.
As you say, "Works straight out of the box" and "one click and thats it" are statements one took for granted with Apple,but with a big push coming from the suits, perhaps things are shipped too early.
From what I had heard of Apple, I would have expected better.
It was amazing to read the frustrations of Mac veterans in their efforts to get the Time Capsule up and going - and they appeared to know what they were on about.
I have to admit that I wasn't quite sure at first what exactly I was installing, but settled for a wireless external drive on my existing network, which doesn't have any other Apple products.
Even that setup has gremlins.
I am hoping that soon one of the mags will devote a feature on clearing the decks and starting from scratch with DETAILED instructions. I found that the installation bumpf which came with this brick stopped at the point where things got tricky.
Keep the faith!

Could Calendar services not available after reboot be LDAP problem?

I followed this installation guide:
https://wikis.oracle.com/display/CommSuite7U2/Communications+Suite+on+a+Single+Host+%28Linux%29#CommunicationsSuiteonaSingleHost%28Linux%29-InstallingCommunicationsSuite7Update2Software
I have successfully installed and set up the Oracle UCS Sun7 update 2 server. Calendar works ( if I don't reboot the server ).
However, when I reboot the server, Calendar service is unavailable.
Important information for when I installed Oracle UCS sun 7 update 2 by following the installation guide:
I have noticed when browsing through the folders, that there was already a 'dsee6' folder for the Oracle Linux I started from. Following the example installation for the Oracle Linux 5 with GlassFish install, I was instructed to download a new Directory Server. Following the instructions on page 7 of the install guide listed above, I made another folder 'dsee7'. I am wondering if I should never have downloaded this new Directory Server as instructed on page 6 "Get the Software". The install guide actually does not mention where to get the Directory Server from, so I just went to the edelivery site and figured it out myself. Anyways, under the "Installing and Configuring Directory Server" section, #3, I was instructed to "mv dsee7 /opt/sun/directory". In this folder, /opt/sun/directory/bin, there will be "./dsadmin" utility that can be ran. This is used to do many things with the Directory Server including starting it. Here is how I started it:
cd /opt/sun/directory/bin
./dsadm create /var/opt/sun/directory/dsins1
./dsconf create-suffix "0=isp"
Also, I downloaded the Directory Server from edelivery - Oracle Directory Server Enterprise Edition 11gR1 Patch Set 1 for Linux x86-64
Then, I ended up running to get it set up:
./dsccsetup ads-create
./dsccsetup war-file-create
$ ./dsccsetup cacao-reg
./dsccsetup status
Then, it looked like the dcss agent is registered in cacao.
So, if we forward ahead to page 9 of the install guide, "Preparing the Directory", I ran this and prepared the directory. After I finished installation, I could restart the Directory Server with no problems, as long as I did not reboot the machine. I would restart the Directory Server like so:
cd /opt/sun/directory/bin
./dsadmin stop-domain domain1
./dsadmin start-domain domain1
However, if I rebooted the machine, I could still start and stop the Directory Server as noted. But, the Calendar Services were not available.
The only reason I wonder about this LDAP Server possibly being the cause of this is because I had at one point configured the services to start on boot. I followed these instructions:
https://wikis.oracle.com/display/CommSuite7U2/Start+and+Stop+Scripts+for+Communications+Suite+%28Linux%29
I am using a VMSphere client to host this set up. So, since that point of configuring the services to start up, I have rolled the snap shot back so that the services are no longer set up to start on boot. But, when they were, and I rebooted the machine, I could see ldap 389 errors all over the place. So, that lead me to roll my snap shot back in effort to try and fix the ldap errors. I no longer get LDAP errors since I rolled my snap shot back. But, like I said, I no longer have any of the services, including the LDAP, to start on boot as noted in the above link that instructs us how to do this.
After reboot, I run these commands to get the server up and running:
Start GlassFish server:
cd /opt/sun/SUNWappserver/bin
./startserv
Start web ( Messaging Server I think ):
cd /opt/sun/comms/messaging64/bin
./start-msg
Start LDAP ( Directory Server )
cd /opt/sun/directory/bin
./dsadm start /var/opt/sun/directory/dsins1
Start Mysql
cd/etc/init.d
./mysqld start
All of those commands complete without problem. I can log into the convergence web, I can hit the delegated administrator, I can log into the GlassFish admin console, and I can see my calendar folder when I hit it in the web ( http://myServer.com/davserver/dav/home/userName/calendar/ ).
So, in summary, I am wondering if anyone knows if this supposed second Directory Server is causing my problems since I started with Oracle Linux 5 and Oracle Linux 5 appeared to have the folder dsee6 already installed with it. Could this be why my calendar services are not starting after reboot but are working before reboot?
( Also, all of my posts keep getting deleted. Can someone please email me if someone from Oracle is deleting my posts and tell me why they are getting deleted? )

Not really a Time Machine question, but my wife, not realizing an external USB hard drive was connected to my macbook, pick up the laptop and the external drive dropped on it's corner...slight damage. It is a 320Gb hard drive with three partitions....two for storage and one for time machine backup. The two storage drives are mounting find and seem OK, but the time machine partition is not mounting. Disk Utility sees the partition but can't mount or repair it and gives me the error "Invalid sibling link, unable to verify or repair."
Any ideas on what I should do next (other than back up the other two drives)? Should I try erasing the disk and see if it'll mount?
Thanks,
John

If you have +Disk Warrior+ (4.1.1 or 4.2 only), or another heavy-duty disk repair app (that you're certain is compatible with Leopard), it might be able to repair the partition. DW is about $100, so unless you think you may need it for other things in the future, it may not be worth the chance.
Otherwise, if Disk Utility can erase it, it's probably ok. In this case, though, it would be worthwhile clicking +Security Options+ then +Zero Out Disk+ to be sure it can write to the entire partition.
Long term, though, I'd be a bit reluctant to trust my backups to it. (Perhaps a hint to Santa?)
Additionally, I am having trouble ejecting the two working partitions. It seems to eject them becuase they no longer appear on my desktop, but I get the "unable to eject...." error message. Not sure what this means.
See what happens after erasing the TM partition. That may clear it up. If not, try mounting them again.

External Hard Drive will not mount after upgrading to Yosemite

After upgrading to Yosemite, my external 3TB hard drive will not mount... can't see in Finder, but does appear in Disk Utility. Follow steps to Repair disk, but get a message that D.U. cannot repair disk.

LaCie external HD does not mount after lion 10.7.2 upgrade

After the upgrade to Lion 10.7.2, my external LaCie 2big Quadra (connected through FW 800 to a MacMini late 2009) was no more visible to the system.
This has not been the first issue with this disk since I have Lion: after the upgrade fron Snow Leopard to Lion, the "Ignore ownership" flag of the volume was resetted to "marked" (which was a mess because I had my whole home folder on it).
After the 10.7.2 upgrade, I had no chances to re-mount the volume with Disk Utility (dimmed button) but, using the terminal I was able to find it in the /Volumes mountpoint and to recover my home with the ditto command to the MacMini internal drive.
After this I reformatted the disk and now it seems to beave properly but I have seen on the web plenty of troubles regarding FW management under Lion and I am not sure if it is a good idea to trust it again.
Does anybody have suggestion or news?

My Lacie ethernet mini is not working after Lion upgrade.
Finally got an admission from Lacie that the login software won't work with 10.7 and they suggested going back to Snow Leopard . . .
Apparently the login software cannot be changed or overwritten so now Lacie drives are obsolete when using Lion.
I wish there was a way to wipe it clean and use it without the login software, but they couldn't suggest a way.
I note you may have had better luck but I don't know how to use terminal, so I may have to junk it, or possibly take out the drive and buy a caddy for it?

External drive not mounting after crash

I had the finder lock up on me and I had to force a restart.
At the time an external USB2 drive was plugged in. Since the forced restart the external drive is not mounting. It won't mount via USB2 or Firewire. It is formatted as Mac OS Extended.
Upon booting the computer notifies that it can't be read and asks to initialize, ignore or eject.
The system profiler sees it. Disk Utility sees it but it won't allow the options to verify or repair to be used.
Disk warrior, Drive 10, and Disk Rescue won't allow the drive to be fixed unless its mounted. In fact the drive won't even appear as an option in those programs without mounting.
So what do I have left to try?

After trial and error and moving the drive around to various enclosures I had Disk Utility open up the options to verify and repair.
It wouldn't actually fix it or go through the whole process of fixing it but that was enough to let a boot from the Disk Warrior CD see the drive as an option.
I only recovered about 60% of what was originally on it after DW redid the directory but it was at least something.
One question though what sort of issues could my boot drive's directory have that would effect the external ones? Is the corruption the fault of the internal drive?
I ask because although I've been assured that it will work fine I am running a 160G drive in a machine that only sees the first 128GB as the boot drive. I am not 100% positive that won't have some side effects but everyone around here seems to tell me its all good and that I shouldn't worry about that. Its this belief that makes me use the external drive as my torrent media drive since there is so much more reading and writing being done to it.

External hard drive not mounting after Leopard install

Installation seemed to go ok, but when I switched on my Maxtor One Touch II drive nothing happened. Doesn't appear in Disk Utility but I can see that it is attached when I look at System Profiler. Any ideas what to try next?

After giving up on the upgrade of leopard I decided to do a clean install (to get rid of all the junk) My Lacie 800 and 400 fire wire drives mounted with no problem. It turns out my seagate fw 400 drive daisy chained off my would not mount and cause the other drives not to respond in the finder till I removed the Seagate drive and then the other two drives worked fine. I daisy chained my Firelite 400 and it mounted fine and its being used for time machine. So far haven't been able to solved this problem, the Lacie and Firelites work fine.

Time Machine disk not mounting after sleep

Greetings,
I am having a problem with the external USB disk (500GB Iomega) that I have set up for Time Machine not remounting after my iMac wakes back up. Nothing I have tried, short of rebooting, seems to cause the Mac to notice the drive. I have tried turning the drive off and back on, but that didn't work, and neither did unplugging and re-plugging the USB cable. (I suppose obviously) Time Machine won't do any backups and complains that "The storage location for Time Machine backups can't be found." Time Machine Set Up says "Next Backup: When Disk is Connected." If I reboot, the disk will show up and Time Machine will commence backups, but then, after the machine sleeps, I have the same problem again.
When I first plugged the drive in last night the computer immediately recognized it, mounted it, and asked me if I wanted to use it for Time Machine. I didn't have to do anything. I then successfully started Time Machine and it did its initial and several hourly backups as expected. Then the machine went to sleep and the disk never came back (short of a reboot).
The computer is a brand new 24-inch, 2.8Ghz, iMac with Leopard installed from the included DVD immediately after opening the box - I did nothing before installing Leopard.
This is my first Mac (I am a Unix refugee) so I may very well be doing something entirely stupid, but surely external disks should still be mounted (or automount) after the computer returns from sleep. What am I doing wrong? I also don't see any way to force Leopard to mount the drive, but I probably just don't know where to look.
To be completely clear... the drive is plugged directly into the iMac on USB, no external hub. There is no networking involved with this disk. I didn't make any kind of settings to the disk (either to the disk itself- there aren't any, or on the iMac when I plugged the disk in). The only thing I did was answer "Yes" when Time Machine popped up a window asking if I wanted to use the new disk for backups. Last time the disk was mountet (before the computer went to sleep again) I ran the Disk Utility and it said the drive was fine.
Thanks,
Mark
P.S. I'm sorry if this has been discussed elsewhere but I couldn't find it. Like I say, I'm new to the Mac and to these forums, so please forgive me if this post is redundant.

Ok, I went into console, and forced my iMac to sleep to see what the console would show was actually happening. I am not a very computer savvy person, but this is what the console said:
Nov 8 21:50:27 steve-freunds-computer kernel[0]: USBF: 48332.754 AppleUSBEHCI[0x52ab000]::Found a transaction past the completion deadline on bus 0xfa, timing out! (Addr: 3, EP: 2)
I believe this may be related to the problem. The AppleUSBEHCI appears to identify the offending driver/controller as the EHCI controller (Enhanced Host Controller Interface), or the controller that handles usb 2.0 High Speed (usually usb 1.1 and 2.0 Full Speed are handled by something that would be called a UHCI or Universal Host Controller Interface) USB High Speed is the fastest of the three usb speeds and although the interface is compatable with the slower speeds, works rather differently than the other two. Beyond that I'll have to look into what this message means (I'm brand new to the Mac - I've only had this one a couple of weeks).
*Could others that are seeing this problem please post how many usb ports on the computer, not total devices connected to hubs or anything, but actual, physical ports on the computer that they are using?* Experimenting a little, on mine at least, I have not had the problem discussed in this thread when only two (out of the three available) of the physical USB ports on the Mac are used. Again on mine at least, it also doesn't seem to matter what, with the exception of external hubs, is plugged into the ports. Replacing the external drive with a flash drive or iPod Touch produces the same results, so it doesn't appear to have anything to do with the Iomega drive that I started seeing the problem with - it may be that that was just the third thing I plugged in (or not - I realize that I am a sample of one).
It also seems to be that things connected to an external hub continue to work after the other two ports have failed. This is probably why most keyboards (mercifully) keep working - they are usually hubs (Apple's external ones are). I can't guarantee this however because I haven't really tested it - just observed it so far to be the case for me so far. Hubs do work differently than ordinary usb "functions" as the usb spec calls them.
Lastly...
If you have Xcode installed (assuming you have it installed in the default /Developer location) there is a tool in /Developer/Applications/Utilities called "USB Prober" that can provide some useful USB information.
In my case, once a device stops working I see the status of the non-functioning devices reported as:
High Speed device @ 2 (0xFA200000): ............................................. External HD (did not respond to inquiry - 0xe00002ed, might be Suspended)
High Speed device @ 3 (0xFA400000): ............................................. HP Color LaserJet 2605dn (did not respond to inquiry - 0xe0004051, might be Suspended)
And indeed the usb ports in question do appear to be behaving as if the host (the Mac) has them suspended - but I can't be entirely sure. I will try to look into this some more later if I can.
Thanks,
Mark
P.S. To save questions: I've tried all the easy stuff: Switched cables, swapped out the hub I have on one of the ports, tried different devices in the ports (so far an HP printer, Iomega external disk, iPod Touch, and Sony usb flash drive). Nothing resolved the issue. My keyboard and mouse are connected to a 2.0 High Speed hub. I've tried using another hub, but it didn't make any difference.

Z400 Discs with EFI partition not mounting after Win 7 Pro upgrade

HP z400: After a repair/upgrade of Win 7 Pro (64) sp1, any external disc with an EFI partition will not mount. Drive will be present in BIOS and Disc Management, though without a letter. Unable to assign a drive letter. All other discs mount correctly. Drives with EFI partition will mount on other PCs. All drivers appear to be current and fuctional.
This question was solved.
View Solution.

I figured it out... after two weeks of head-scratching, I finally found the cause.
I run MacDrive 8 so i can read discs with HFS+ formatting. That program needed to be fully uninstalled and re-installed after the upgrade. I had de-activated it prior to the upgrade, but it needed more than that. Everything works now as expected.
But wouldn't it be ince if Windows would read mac discs natively?
