NSS4000 Volumes not showing up after powerfailure

Hello,
A little background info.... my NSS4000 had the internal firmware damaged with a reboot/powerloss within a few months of receiving the machine back in 2007... so I do use the external USB Boot loader to start the box; and it has been working great since.
   My reliable IT staff moved my UPS and my NSS4000 went through a few unexecpected power cycles in the freak snow storm last week in Connecticut.    When power was stable, I noticed my shares were no longer accessible.   Logging in to the device I see the following on Storage/Status page:
I was able to save the configs to a USB drive and it shows my missing volumes in fstab (maybe there is more to it when mounting volumes from a raid device):
/dev/RAIDA/privatevol               /mnt/RAIDA/privatevol          xfs          defaults,usrquota,grpquota          0 0
/mnt/RAIDA/privatevol/d               /mnt/ftp_dir/d          none          rw,bind          0 0

/mnt/RAIDA/homevol/.autohome/               /mnt/ftp_dir/homes          none          rw,bind          0 0
I am not sure what to look for in the log files... but I do see messages that seem like there may be other problems... in dmesg and messages I see the following type of errors:

I don't know if these type of messages existed before my problem... they certainly don't look good to me.      My thoughts were to try booting up with a drive missing (but which one should I take out)... or looking for another NSS4000 on ebay and putting the drives in it.
Any ideas?
Thanks
Mike

To anyone that may find themselves in the same situation...
I think it is back up and running.  I wasn't sure if the NSS4000 was dead... so I did the following:
1. made one "Save of the current configuration"
2. powered off
3. popped out the drives (labeling the position of course)
4. powered up with a new drive to test creating a new jbod array and volume (which failed with the same type of errors in my original post.)
5. Restored All Settings to Factory Defaults
6. Rebooted
7. Was able to create new JBOD Array on single drive with volumes (tested CIF and FTP.. worked this time)
8. Restored the configuration that I saved on Step 1
9. I let it fully reboot... and powered it off (still had wrong drive in)
10. Put original drives back in
11. Back in Business!!!!
I'm not sure why restoring factory defaults cleared out the problem... but I am glad I didn't lose my files.
Mike
PS... how do I mark this conversation as Answered and no longer a question?

  • External Volumes not Showing up after Security Update

    Here are the basics: i have a first generation PPC mac Mini (10.4.11) that has a Ministack external harddrive/hub attached to it. I installed the latest Security Update via Software Update with the drive attached (bad idea, i know) and now the drive won't mount on the desktop, does not show up in System Profiler, and doesn't even show up in Disk Utility. It DOES show up when I do a Volume listing in Terminal, so it appears to me that at some level the computer still recognizes that it's there. Also, I attached another external drive that I have and I get the same results with that.
    The additional ports on the hub portion of the drive continue to operate without any problem.
    So far I've tried repairing permissions, resetting the PMU and PRAM, even archiving and reinstalling the OS to no avail.
    Any ideas?

    Hmmm, I've heard about the worry of disconnecting externals during an update, but my Mini/PPC was updated to 10.4.11 with a Ministack v1 connected without trouble!?
    Seems you've tried about everything... how about Pulling the RAM, trying to Boot, then reinstalling the RAM?
    How about booting off the Install Disk, does it show in DU then?
    How about Does it boot into Open Firmware with CMDOption+of ?

  • OHS 11gR1 web-page not showing up after creation, registration of webgate

    Hello there,
    The OHS webpage on host:7777 is not showing up after I created, registered the webgate on oam 11g console. I copied the 2 artifacts into the ohs proxy server box in the webgate/config folder and restarted OHS instance but now, the ohs page won't show up. The opmn status says its alive but it doesnt show up in the browser.
    I have oam 11.1.2 installed with webgate 11.1.2 and ohs webtier 11.1.1.6.0. Am I missing any step? Do I need to create a authentication scheme before I check it? Please advise to the earliest convenience.
    Thanks!!

    Hi,
    You need to create authentication scheme. also create resourse for index.html page in OAM console and add it to protected resourse list. So when you will access OHS with 7777 port it will redirect to OAM SSO page, after successful login it will take you to the home page of OHS.
    mark, if this helps.
    Regards,
    Kishore

  • The templates are not showing up after I select them???

    the templates on pages are not showing up after I select them....unless I highlight the entire page and select a particular colour.  That leaves all the colours in the photo off.  Any help would be so very helpful.   

    CeraG - It will help to answer if you supply your system version, pages version and if you lately have done anything to the computer (installing, uninstalling etc)
    I think you have forgotten to do a Software update or it could also be a font problem but more info from you is needed!

  • Why is it not showing anything after I plugged in my USB hard drive? I cannot locate the drive in my macbook. FYI this happened after few times using it.

    I need help as I am new to IOS.
    Currently it is not showing anything after I plugged in the hdd to my mac book.

    I had the same exact issue, which you can see in another forum.
    I "killed" both my MBP and my wife's MBP by plugging in my iPhone and getting a  message about USB drawing too much power.
    It was not fixed by using an SMC reset.
    I DID fix it by unplugging the battery, I left it unplugged long enough to remove the RAM, HD and put some RAM and HD back into place. (I initially swapped the RAM and HD from my MBP into my wife's MBP.
    After that everything was good, although upon first boot, some apps crashed because of the "system date" being set to a date before 2000. I forget the exact date, but it will be some time in 1984, the birthdate of the Macintosh. It is not a big issue, just correct the date and time.
    If you are curious about that date, copy a large file on your drive and look at the CREATED/MODIFIED date....it will show this same date, until the copy is complete, at which time you will see the correct one.
    Once again, try to disconnect your battery, very carefully by lifting up the connecter evenly on both sides to avoid damaging the connector or the board.

  • I am trying to update a chart in Pages that I created in Numbers, but the refresh button does not show up after I save the Numbers file. Thoughts?

    I am trying to update a chart in Pages that I created in Numbers, but the refresh button does not show up after I save the Numbers file. Thoughts?

    It is hard to exactly understand what you have  done or not by you one sentence description. My thought is have you read in the Pages User Guide? Here is what it says about updating a chart in Pages:
    Updating a Chart Copied from a Numbers Document
    If you’ve created a chart in Numbers, you can copy it and paste it into your Pages document. After it’s been pasted into Pages, the chart remains linked to the data tables it references in Numbers. To change the chart data, open the original Numbers document and edit the data there, save the Numbers document, and then refresh the chart data in Pages.To update a chart after you’ve updated its linked Numbers table:
       Select the chart on the page and click the Refresh button that appears.
    Note: You must save the Numbers document before copying and pasting your chart into your Pages document and after editing the Numbers data tables that the chart references.
    I hope it has helped you.

  • Table not showing data after refresh

    Hi gurus ,
    A unique problem We have added a field in the custom table . once moved to quality system it is not showing up the data whwn when we do a select query on that table in se16 . say total entries are ten thousand four of them are checked and when display not checked i.e eq space we get just 100 entries on number of entries ..i asked to regenerate the table in quality system but it did not help .The Quality system was refresh 1 month ago and we see it not working after it ..please suggest the correct steps we need to perform  to recover the data . Adjust database with keep data has already been done ...

    Hi Anjaneya Bhardwaj,
    If I understand well, your issue is that you have a SELECT in your program, saying newfield is your newfield, something like:
    SELECT ... FROM ztable INTO ... WHERE newfield = space.
    and it doesn't return the records that existed in quality before newfield was added.
    It it because, by default, when you add a field to an existing database table, with records already present, they are assigned the NULL value, which is different from space.
    They can be retrieved using WHERE newfield IS NULL.
    Usually, to avoid this issue, when we add a new field, we tick the "no null value" checkbox for this new field, in SE11 transaction. That will initialize the field of existing records, to the initial value (space for characters, 0 for numeric fields, etc.) Note: maybe it can be counter performant for big tables...
    Solution for your issue, run this code once:
    UPDATE ztable SET newfield = space WHERE newfield IS NULL.

  • My imported backup html files from another computer do not show up after import

    I am currently transferring files from my macbook pro to a pc netbook. I already exported my firefox bookmarks via an external drive and accessed the html file on my new netbook. After importing the html on firefox on my new netbook, the bookmarks do not show up on my bookmark list.

    Please see this article on how to move your bookmarks and settings from one computer to another: [[Moving your Firefox bookmarks and settings]].
    Caution: Restoring bookmarks from a backup will overwrite your current set of bookmarks with the ones in the backup file.

  • Mail not showing accounts after ios 7 update on iPhone 5

    After the ios 7 update to my iPhone 5 mail does not show my accounts. Specifically there is nothing below the word Accounts. The rest is working fine and still connected to my three accounts. However it no longer shows accounts.

    thanks for the suggestions, i tried the ideas you suggested but i dont even get a camera showing for the rear camera, i also noticed the torchlight no longer works.  i did all the steps but no luck.
    So I took my camera to the genius bar this weekend as well as walking through various steps with the apple guys in ohio support over the net. 
    With the guys at the genius bar, after i insisted that it must be software as the rear camera stopped working only after the softwre update, they continued to assure me it was hardware and talked me into letting them replace the camera,  they then took it to the back and tried fixing a camera and 30 minutes later came out and said the rear camera is no longer being detected and wanted me to replace the motherboard for yet more money.  im glad they didnt charge me for the new camera though as it still didnt work.
    anyway the motherboard idea i rejected as it was just 2 months out of warranty and had only stopped working the day after the release of 7.0.2, so im going to wait until the next few releases to see what happens, as i dont believe for a second its hardware.  i expected a stock answer from apple and its exactly what i got even after my explanation of how it was working the day before the release.  not overly impressed with the whole process.
    i wanted to back down to 7.0.1 to confirm the camera still works but they said no chance so i cant even see if it still works ouside 7.0.2.  anyway will update if i get any further progress.

  • Texts are not showing up after upgrading to version 11

    Could someone help me with why some of my texts are not show up on my Flash project? Before the upgrade, everything is fine. However, after upgrading to version 11, my texts are disappearing.
    Before (version 10.3.183.7...)
    After (version 11.0.1.152...)
    The texts in the boxes will disappear, when I hover mouse cursor over it. Those boxes with texts in them are created with an external AS file, and the texts are dynamicaly changed/put in with an external XML file. There is a mask on the boxes, show only 4 at a time.
    Demo: www.ethanslin.com/portfolioWorks/flashWorks/demo/
    You will see the changes with Flash player version 11, and everything working fine with older versions.
    I use iMacs with Snow Leopard and Lion, and this happens on all of the browsers with Flash Player version 11.01.152. I also tested on Windows 7, and it is still happening. Is this a Flash Player bug or something changed that I am not aware of? Is there a work around for this?

    This is a known issue and we have a fix for this in our next release. Thanks for posting.
