Unable to make tWo concurrent logins to the firewire Hard Disk from RHEL 3.

Hello
I tried setting up a firewire(shared storage) ORACLE 10 G RAC CLUSTER using OCFS/ASM using your install guidelines
but this failed.Below is the scenario.
Hardware : compaq intel PC's with 1 GB RAM
Members in the cluster : Two
Operating system : RHEL AS 3 / FEDORA CORE -3 (both being tried one after the other)
Oracle 10G RAC version : 10.1.0.3.0
HDD : Maxtor one touch II 250 GB with combo interface Firewire/USB 2.0
N/W Adapters : Two public interconnect,Two private interconnect thru 10/100 internet Hubs/switches
Firewire card details: FireWire (IEEE 1394): Agere Systems (former Lucent Microelectronics) FW323 (rev 05)
Failure Description
I successfully loaded the drivers for the Maxtor one touch II in the two Linux (RHEL 3) boxes. But after a restart, at any point of time,
the disk is detected only by one node. It is detected in the other node only if the first node is powered OFF. On investigating we found the
following error message by running "dmesg | grep sbp2" command as root
ieee1394: sbp2: Query logins to SBP-2 device successful
ieee1394: sbp2: Maximum concurrent logins supported: 2
ieee1394: sbp2: Number of active logins: 1
ieee1394: sbp2: Error logging into SBP-2 device - login failed
Please do suggest where i was wrong and how to proceed next.
Thanks & Regards

Hello All,
I work as the system admin for Raghavan. Thanks to all those who took time to reply to our queries. Sorry for the lengthy mail. Let me go through the whole sequence of what we did initially.
1. Installed RHEL 3 with Agere PCI Firewire cards.
2. Installed Firewire Kernel kernel-2.4.21-27.0.2.ELorafw1 on top of it.
3. Modules were loaded properly and the Firewire hard disk was accessible from both the nodes.
4. Everything went fine during OCFS and ASM installation.
5. We were installing the CRS and that too went fine till 99% and the final step of running the root.sh in one of the nodes gave an error message as follows
"Failure at final check of Oracle CRS Stack
0"
6. So we thought of reinstalling CRS and deleted the Voting disk file directly from the shared disk. We deleted the file manually from one of the nodes using the "rm -rf" command and that too before uninstalling OCFS.
Now both the disks went out of sync. The voting disk and CRS file was still visible from the other node. So we did a reboot of both the nodes one by one. After this MYSTERIOUS reboot at any point of time only one node was able to detect the hard disk.
Finally after nearly two months of head scratching (really lost lot of my hair in this :)) we were able to get concurrent logins from both the nodes now! Thanks to the reply by Member no 279089. I bought and installed a TI(TSB43AB23)card on one node and a VIA chipset card on the other. And finally the magic worked. I am able to partition the disk and the partitions are visible from both the nodes.
But now we have a new problem. When we invoke the OCFSTOOL from one node (VIA card node), the previous OCFS partion (the one which was done before the MYSTERIOUS reboot) is still shown. I removed the /etc/ocfs.conf file and still it is being shown in the ocfstool. I tried to ignore this and continued creating the OCFS partition from the other node (TI card node) using the mkfs.ocfs command. That too ran fine without any error messages and was able to mount it under /u02/oradata/orcl. When I try to mount the partition from VIA card node it is giving me the following error
# mount -t ocfs /dev/sdb1 /u02/oradata/orcl
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, or too many mounted file systems
I get the following in /var/log/messages
Jun 29 21:16:40 testrac1 kernel: SCSI disk error : host 2 channel 0 id 0 lun 0 return code = 8000000
Jun 29 21:16:40 testrac1 kernel: Current sd08:11: sense key None
Jun 29 21:16:40 testrac1 kernel: I/O error: dev 08:11, sector 69
I tried googling with the above error message and they seem to point hands towards VIA chipsets. But I am not sure. Please guide us on what needs to be done to resolve this issue if you have faced it before.
Thanks in Advance
Jei

Unable to establish two-way communication with the printer

I have a HP Photosmart B8550 large format printer, but failed recently to print the whole page, but only one third of the page. The OS is Window 7 in my commuter. I downloaded the driver from HP website, but it is not working. The result of the failure is "The computer is unable to establish two-way communication with the device." One of the reasons I guess is that I failed to register my printer because I had no way to finish the registration, because there is no further process even if I put my printer name or number into the required block. Anyhow I failed recently to print anything in the printer. I am seeking the support after a lot of tries. Thanks.

I have two HP computers and two HP Photosmart B8550 printers. A month ago printers were not working. I tried in vain in two computers to download new HP software and driver from internet and got the HP Solution for install error - Windows 7. Based on this Solution on desk, I tried many many times to follow every step, but the result is the same: Fatal error during the installation.
By using other tools like HP Printer Diagnostic Tools, HP Print and Scan Doctor, I failed too because the diagosis or the choices are not accuate. For example, the printer is disconnected. It is wrong even if I changed ports and USB calbe again and again. The control panet can prove that there is communication, but the printer cannot work as directed. There is no way to test the printing as Doctor requested, saying the computer is unable to establish two-way communication with the device, which is not helpful to go ahead with the solution. There is no way to register the printer because there is no such a model HP Photosmart B8550 in its list after search.
It is even worse that the new window dialogue asked me to find HP Photosmart Essentials in my computer to install it again and again, and I could not concel the request whenever I open my computer.
I guess the HP printer software and driver has something wrong in its root design, which leads me to failure in installation so that the computer could not recognize my printer. In short, the new HP software and driver makes my printer not functional.
By the way, my two printers can work internally in printing sample paper and report and two computer are working in perfect condition.

Sometimes and this is network dependant if they suspect the phone to be lost or stolen as in this case with change of Sim card and provider then the origonal network can and some will block the phone untill you have rang them and proven it's not the case or if you have bough this 2nd hand then the origonal seller may have stopped paying the contract bill and thus the phone is blocked

Unable to change or disable the KNOWN Hard disk password in BIOS

Hello,
I am having few problems with my new TP W500. I have enabled BitLocker Encryption in Vista Ultimate SP1 after I got my laptop and disabled it later. After a while I noticed that HD password option along with the passphrase option in the BIOS got grayed out and I cannot make any changes to the HD password. I know the HD password, system is booting up after I enter the HD password but very same password for the same hard disk is not working when I plug the Hard Disk into my TP T60p.
Called Lenovo support in Atlanta but they could not figure it out. They think HD got stuck encrypted eventhough I decrypted with BitLocker and formatted. Also called Hitachi and they don't have any idea about it. I also cleared and turned off the TPM in addition to clearing and disabling the security chip but non of these actions were helpful to disable or change the KNOWN HD password. I wonder if reflashing the BIOS would solve it.
I would appreciate if anyone has an idea about this issue.
Thanks.
Solved!
Go to Solution.

Just wanted to get back with this issue in case someone else is having the same problem. Lenovo finally decided to replace the mother board on my laptop and this issue finally got fixed. Now I am able to remove/change my hard disks passwords.

Whow that is a long time ago. If I remember well, even then bookmarking was enabled by default, Resume Data were sent. Did you try it out on the LMS? Because even though all claim to be SCORM compliant, they don't always have all the functionality

Unable to access TC hard disk from PC

I have been unable to access the TC wireless and hard disk from my PC. I have both a Mac and a PC...the Mac works fine. I'm not using the TC to access the internet I just want to use it for back up and file storage for now. The message i get from the pc when i try to access the airport disk is "could not connect to the disk. Make sure NetBIOS is enabled and try again (53)."
I have tried to add the IP Address to my Norton software, I have even disabled Norton and that didn't help. I have tracked down the secret location of the NetBIOS and made sure it was enabled...but i get the same message.
Anyone have any other ideas? I love the TC for MAC but i need it to work for both systems or I'm going to have to take it back! Please help!

Ok...I stumbled onto the solution after being told by several people to have windows rebuilt and almost charged $130 from Dell Tech Support!
While attempting to share files from my Dell to back up on my Mac in order to reformat windows...yea it was getting to that point...Windows had me run the network setup wizard. During the set up there is a "file and printer sharing" choice to make and the default is of course "turn off file and printer sharing" which is of course the key to accessing the TC.
I did complete the setup for a new network, renaming the workgroup and making sure the other settings jived with all the TC settings I have thrashed through for nearly two weeks.
I hope this saves someone a little time and a lot of frustration. Thanks to all the other posts about this issue, it was good to know that other people face the same type of problem and there were a million ways around it.

I tried on two macbook air, same situation.
This never happen on 10.10.2 or previous version. (The HDD light will off and it will stop running after I ejected before.)
I feel unsafe to unplug the external hard disk when its still light up and running.
I am using Macbook book air 2012 and 2013 with seagate backup plus....
Anyone have same problem? how to fix it?
or its ok to unplug the HDD while the HDD light is still on and running?
MacBook Air, OS X Yosemite (10.10.3)

I have a G-Tech external hard drive that continues to spin after I have unmounted it and if I disconnect it while it is spinning it makes a very nasty sounding clunk noise. In my case it started doing this after I enabled FileVault a couple of years ago. I have found that if I unmount it and then wait 6 minutes it will stop spinning. It is inconvenient but I only use it once a week and the clunk sound is scary enough that I put up with the wait.

HT201269 I am trying to save memory on my iPhone 4S/ ios6. Can I back up all photos to icloud and the external hard disk I normally use for photos? If I then delete photos from the iPhone do the get deleted on iCloud?

I am trying to save memory on my iPhone 4S/ ios6.
1) Can I back up all photos to icloud and the external hard disk I normally use for photos? If I then delete photos from the iPhone do the get deleted on iCloud?
2) Can I back up the newsstand to iCloud and save memory on the iPhone?
3) Can I back up the bookshelf to icloud and save memory on the iPhone?

1. What format is the external drive? It sounds like it's ina format that Macs can't write to. Is it a NAS or NTFS?
2. Easiest thing: just move your iPhoto Library to the external
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

HT201250 i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. do i keep my files in the portable hard disk when I connect it again with the macbook or the time machine will era

i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. Am i keeping my files in the portable hard disk when I will connect it again with the macbook or the time machine will erase all?
I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard drive

Welcome to Apple Support Communities
Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.
If you want more information about Time Machine, read the Pondini's site > http://pondini.org

Is it possible to upgrade the internal Hard disk drive on the iMac

Is it possible to upgrade the internal Hard disk drive on the iMac?

Yes but it's definitely not advised. If you have a machine newer than 2009 Apple uses drives that have integrated heat sensors. This makes upgrading much more difficult but not impossible. If you have a machine still under warranty then definitely DO NOT do this yourself as you may void the warranty not to mention it isn't for the faint of heart. Take the machine to an AASP to have the work done, you will need to find one in your area willing to do so.
If you are considering a new machine then simply buy the configuation you need.

Disk Utility Unable to Repair External FireWire Hard Disk

Hello all.
This is the External FireWire Hard Disk that has been giving me problems for days, it is a Backup/Clone Disk of my sis's Mac mini Core Duo, and may explain why it was so hard and took so much pain to copy some of the data out, at times it failed to mount, and I manage to rescue some data after using Disk Warrior, but Disk Warrior was also unable to replace it with a new directory.
Anyway, so I (was able to) mount the hard disk, and I was successful in erase and reformating it.
But when I (try to) repair it with Disk Utility's First Aid, this report is what I get:
(The usual 'Checking...' text lines, text in BOLD indicates RED colour text)
Checking HFS Plus volume
Checking Extents Overflow file
Checking Catalog file
Checking Catalog hierarchy
Checking volume bitmap
Volume Bit Map needs minor repair
Checking volume information
The volume Untitled could not be repaired after 3 attempts
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Repair attempted on 1 volume
1 volume could not be repaired
Then a window dropped down from the top says:
First Aid failed
Disk Utility stopped repairing "Untitled" because the following error was encountered:
The underlying task reported failure on exit
(OK Button)
I guess this hard disk is really a gone case?? I am quite OK just to replace it with a brand new one... maybe all the trouble I had in the beginning is because I may already have a faulty backup drive to begin with???
Thanks and cheers

Hi Kappy,
I knew there was something about "not mixing" PPC and Intel versions of dealing with the external drive.
The drive was originally prepared on an Intel Mac mini Core Duo. But it should also mount normally on a PPC mac as an external hard drive right?
Here's the sequence of events:
1. Tried to boot from the Back Up/Clone Drive of the Mac mini Core Duo, through my MacBook Core 2 Duo, but failed to boot up
I had to shut down the MacBook (prolonged Bluescreen)
2. When I reboot the MacBook, and tried to mount the ext drive as normal, nothing happens, I knew something was wrong
3. Able to reach the vendor, use the Mac mini again to erase and reformat the drive, then check with DU, everything is OK
Clone with SuperDuper
After that check again with DU, not everything is alright, there are errors.
4. Brought the drive home, try to mount on my iMac G5, nothing happens.
I did a check on this forum, and the reply was that I should be able to use Disk Warrior 4 (Universal) on a PPC to fix an Intel-based ext drive. I was very specific and detail in my post/question
5. So anyway, I have no other option, I ran Disk Warrior 4 from my PPC iMac G5 and scan the ext drive, trying to fix it.
It reported the drive is too damaged to be replace with a new Directory, but gave me a Preview Mode. I use this to copy some data out.
But not sure if the data is OK or not.
6. After that, I was able to mount the drive in my iMac G5, so I just use DU and erase and reformat the drive, with Zero Data
7. Ran DU again, and that's where I am now, at the very first post, getting error messages that I cannot fix the drive
Thanks and cheers

How can i install windows 7 on my second hard disk while the first hard disk running with windows 8.1

I have Toshiba laptop P-75 model :
this model have two slots for the hard disks , on my first hard disk i am running the default windows 8.1 which came with the original condition (when i bought my laptop) , since i am a civil engineer many of my field programs is not working on the
windows 8.1 version and the rest programs barely works appropriate!
I want to download windows 7 on the second hard disk, thus having dual boot in order to chose which windows i want to use.
thanks in advance
ENGR. Saeed Al-Khaled

You need to consult with Toshiba as this is a hardware specific problem and you may not be able to install Windows 7 dues to lack of hardware drivers and/or the laptop being configure for Secure Boot which Windows 7 does not cope with either.
It is your responsibility to do the research for this project to ensure compatibility and needed hardware drivers.

Networking a firewire hard drive from a Mac and access the drive from a PC

I'm trying to network a firewire hard drive from my Mac and access that hard drive from a Windows XP PC. I can see the main internal hard drive but I cannot see the firewire hard drive. Does anybody have a solution or work around?
Many thanks,
Roy

Thanks SO MUCH! Not only does it work, BUT IT IS FREE!!!!
See, I have two firewire (external) HDs, connected to a Mac, connected to a PC, connected to a USB external HD... now I can share files from the USB HD to the firewire HDs!
Gotta love technology!

The storage where the virtual hard disk is located does not support virtual disk sharing

Hi everyone,
I deployed 2 hyper v vitual machines a while ago, and i did that because I needed to test my current game Project, which is an
online game. However, i've had some problems with my Windows installation then I had to reset the pc by making it a refresh
install. I still have the hyper v virtual disks, but i cannot attach it to a new hyper-v virtual machine. it pops up this message:
"the storage
where the virtual hard disk is located does not support virtual disk sharing". I dont know anything about virtual machines, so I
didnt know I had to make the disk sharable. How can I force to attach the hard disk to a new hyper-v? I dont want to go t
hrough the whole proccess of installing the operating system all over again and updating it....
Any help is greatly appreciated!
Thanks in advance,
Romulo Romero

Hi MrDebugging,
>>
When I Try to add a SCSI Controller, and then I click browse to add a UNC I get this:
C:\Users\Public\Documents\Hyper-V\Virtual hard disks\ClienMachine.vhdx
but I tried placing in different location, and the same problem occurs!
By the way, Im not on a server , I am a domestic user and I am running it on my
Windows 8.1
According to the error message , it seems that it is not a permission issue .
The VM is Gen 1 or Gen2 ?
Generally the error message occurs when you enable "shared vhdx" on standalone/client hyper-v host :
Please try to attach the VHDx file to IDE controller if it is a Gen 1 virtual machine (because only the SCSI controller has the option "virtual hard disk sharing" and Gen 1 VM only can boot from IDE )
All in all , please do not use this feature without CSV or Scale-Out File Server with SMB 3.0 on file-based storage .
If it is not the case , please detail steps what you did .
Best Regards,
Elton Ji
