failure in RAID 6

I have NAS PX6 - 300 d with RAID 6, it records images from surveillance cameras this week one of the drives has failed and the cameras stopped working with RAID 6 should not continue to burn? the drive has been changed and now I can't access the shared folder

PS. Update Firmware for NAS will lose my data that is in the files?

Thank you

I have it
RAID it only protects data, but registration does not continue.

Thanks for the help

  • Pavilion Elite HPE (HPE-210y): Travel in RAID 0

    Hi all.

    Recently, I upgraded my hard drive of 1 TB to 2 TB. I bought two hard drives of 2 TB because I planned to run RAID 1, but after that I cloned one of the 2 TB drives and removed the old 1 TB, I decided to save in a different way.   I have most of the things I wanted to back upward again on the old hard drive and another method seemed to be a better route. My uses of son for a little game and RAID 1 seemed to be struggling against productive and not as safe.

    So, I'll be able to move my new drive 2 TB in RAID 0 with my other new 2 TB drive even if I use one right now?

    Else consider this computer Noob?

    Once more, I find myself at the mercy of the much more educated HP Forum members lol.

    Hello

    HP's instructions for configuring RAID using the AMD RAIDXpert. Read at least twice.

    Check your BIOS settings and make sure that the SATA is set to RAID.

    I suggest you connect hard drives to ports SATA 1 and 2 (blue and white). Among the old HP AMD motherboards we're picky about which ports SATA would be supported RAID.

    BTW - RAID 1 is much more secure that it will provide redundancy in the event of a hard drive failure and RAID 0 won't.

  • Kaboom's RAID

    Howdy.  I have a T720 with a PERC H810 configured as follows.  All the disks are SATA external (custom made) enclosure.  With two cables of SFF-8088 tuned on the disks. So you can not blink a light on a drive for ID.

    RAID 1 (OS):

    SATA 2 x 1 TB drives

    RAID 6 (DATA):

    6 x 6 TB SATA disks (red WD)

    I check this server every month to drive failure.  RAID 1 has no critical data.  RAID 6 is not critical, but painful recreate data that is on it, so I would save it.

    Yesterday, a drive started to make noise.  Sounded like accident bearings or the head.  omreport storage vdisk showed that RAID 1 is 'degraded' - and - RAID 6 was "degraded redundancy".  Check the status of the physical disk has shown however that poth 1 TB drives were very good, and has only a single disk in the RAID 6.  This seemed unusual given that the two vdisks were in a deteriorated condition.  While I have a lot of drives of 1 TB extra on-site I don't have a spare part 6 TB.  I had the next day Amazon a 6 identical to.

    This morning I opened the casing of the drive to identify the HOWLER.  It was one of the drives 1 TB in RAID 1.  Get more confusing that the status of pdisk showed still no 1 t disc failed. I decided to rebuild the RAID 1 first of all, if I traded that for a new 1 TB drive.  When I went into the setup PERC and looked at the foreign config, it showed two disks as foreign, the new 1 TB and one of the 6TBs (who were all original, no traded again).  Also, the RAID 6 showed a missing member.  My gut says it was just the bad disk lost disk config on show as well as foreign, and I wanted to study.  I powered down and checked the serial numbers, moved any cabling, other than to check the seats.

    Repower the RAID controller has lost all the config.  "All readers of your previous configuration are gone."

    I think I'm pretty well sprinkled here.  I plan to try to recreate the berries (without initializing) to get the data, but given that there are some questionable readers (but always enough redundancy), I don't know if this is the right tactic to take.

    If anyone has any other ideas, please let me know.  Thanks a bundle.

    You should have tried to clear the foreign configuration on the disks.

    I powered down and checked the serial numbers, moved any cabling, other than to check the seats.

    It is not normally advisable to turn off the system while the RAID array is in a degraded state and disks in a foreign configuration.

    First of all, try to start the RAID controller BIOS and see if you can be able to import the foreign configuration in order to recover your data. You can try to recreate the table with the original settings, but there is no guarantee that you will recover data required to the foreign State to some readers; and if you did, it may be damaged.

  • PC Doctor BIOHD-2 error code

    HP Pavilion FK484AV-ABA, model m4900t running windows 7 64 bit. The RAID-1 configuration.

    PC crashed. Cannot restart. Starting cold, received error message failure of RAID-1 and two hard drives. PC-Doctor ran and received the following diagnoses:

    Processor, memory, drives hard all OK.

    Diagnosis of startup path

    Error code: BIOHD-2

    ATTENTION: No disk is detected.

    Suggestion: Turn off the system and check the drive cables are attached firmly.

    Given that the PC-Doctor verified that both drives are OK, I'm assuming that the cables were also OK. Any suggestions on what may be the problem?

    Thanks in advance for your help.

    Go into the BIOS to see if the discs are recognized. Post your results here.

    This is an unusual condition for PC Doktor to report. Normally a BIOHD-2 error code means that a hard drive has failed, but I have no doubt that both drives failed at the same time.

  • Remove the W510 RAID1?

    Hi all.

    These past 'issues' with my W500 has me shopping for a new.  PCMall W510... Best sellers

    in stock, etc.  I can really play with computer reliablity, so I bought one.

    He has shown with 2 hard drives in RAID1.  I'm debating remove a HARD drive or not and

    install an optical drive.  RAID1 might be best for reliablitiy long term, but I'm used to make frequent

    backups and would like the optical (by machine) onhand when I need.

    Wonder, since its RAID1, it would be as easy as just turn off the RAID in the bios and taking into

    on the 2nd HARD drive?  or it's much more complex than that?

    (the w510 is of course different from that of the 500.  feels much lighter! -He showed up with a cracked LCD screen and

    goes back... but that's a different question.  with the holidays, I am interested in the resolution of Tuesday... I hope

    PC Mall is well... I was disappointed because I was looking forward to playing all weekend)...

    Thank you all!

    Tony

    Hi outofstepper,

    Sorry to hear about the broken LCD screen

    It is quite easy to remove the raid, but the data will be lost. Take a look at this link which will describe the procedure:

    http://www-307.IBM.com/PC/support/site.WSS/document.do?sitestyle=Lenovo&lndocid=MIGR-75086

    RAID 1 will usually IO a little faster that a single HD RAID 1 is not an option that will replace the need for a backup. You are protected HD failure using RAID 1, but will not be protected against data corruption because corrupt data will be mirrored to the two HARD drives, so even with RAID 1 is a good idea to take a backup of your system. If you always make sure you backup your data, I guess that you can fine without RAID 1, but in the case of a failure of HD, you will need to replace the HD, run a restore and all changes after the last backup will be lost. Using RAID 1, you can continue to work and just replace the drive HARD failed when you get a new one. Two HARD drives will consume more energy as well if the battery life is important to you.

    I got a W510, do not use RAID functions, perform frequent backups and got an optical drive. Need the optical drive so I would have picked that instead of RAID in all cases. I also replaced the HARD drive by an Intel SSD that really gave me a performance boost.

  • Unreadable sectors MD3000i

    Greetings!

    We have a MD3000i that has been in operation for some time. It is configured with SAS 15 x 750 GB disks, and recently we experienced some failures of drives, including 1 on the 2 discs of relief in the chassis.

    Initially, this chassis has been configured with:

    -RAID 6 array (called RAID6-1) with 5 discs - slots 0,1,2,3,4

    -Table RAID10 (called RAID 10-1) with 4 discs - slots 7,8,9,10

    -Table RAID10 (RAID10-2 named) with 4 discs - slots 11,12,13,14

    -2 discs labeled as spare - slots 5.6 disks

    A few weeks ago, we had a drive failure in RAID 6 Bay. What is interesting is that neither the automatically replaced hot spare disks the drive failed in the RAID 6 array. As a precaution, migrate us all the data out of the matrix RAID 6, deleted the virtual disk and re-created as a RAID 10 array.

    This left us with a configuration of:

    -Table RAID10 (called RAID 10-1) with 4 discs - slots 7,8,9,10

    -Table RAID10 (RAID10-2 named) with 4 discs - slots 11,12,13,14

    -Table RAID10 (RAID10-3 named) with 4 discs - slots 1,2,3,4

    -2 discs labeled as spare - slots 5.6 disks

    location - failed drive - 0

    Today, I started to receive warnings about a 10-2 failed RAID array. In this case the hot spare in the slot 5 came as failed and the 2nd disc of alternatives to slot 6 become active to rebuild the 10 failed RAID array.

    So now, we look at 3 failed disks in the array

    but this isn't really my question... just in general information.

    During the process of rebuilding RAID 10-2 I started to receive warnings about the unreadable sectors. A report shows 38 unreadable sectors that have both a failure of logic and physical type. Here's where I'm a bit confused...

    The report of unreadable sectors is indicating that unreadable sectors come from a virtual disk that is on the RAID array 10-2. It is the table that rebuilt today. Readers of this table are now - slots 11,12,13,6 (with 6 being the hot spare)

    * BUT * the unreadable sector report is indicating that the location of the physical disk is enclosure 0, Slot 7

    Storage profile report:

    # RAID 10-2

    0.14

    0.12 [a mirrored pair with the physical disk at the enclosure 0, slot 11]

    0.13

    0.11 [a mirrored pair with the physical disk at the enclosure 0, slot 12]

    0.6 [hot spare physical drive is sparing for disk 0, 14]

    0.14

    ####

    So I have a few questions:

    1. the report of the sectors is unreadable reports numbers of slots that start at 1 instead of 0. This would make the spare drive which comes in the use of the reader with unreadable sectors

    2. the storage profile report does not show a mirror to crack 0.13 this disc has been implemented mirror on the disk in the slot of 0.14 shouldn't 13 and 6 be mirrored between them now?

    To be on the safe side, we are migrate all data out of the RAID array 10-2 of the recently created RAID 10-3 matrix. We are also thinking to remove the RAID array 10-2 and making a RAID 1 array, so that we can use the remaining disks under chassis hot spare parts (pending the delivery of replacement of drives we already ordered).

    Perspectives or suggestions on this are appreciated.

    Thank you!

    Gene

    After reviewing the support bundle the problem you are dealing with is a puncture of the VD. The minimum thing, I would recommend to resolve this would be to back up data and remove the Group of disks. Replace all failed drives. When it says disc 7 the failed drive is actually HARD 6 disc. Then recreate the VD with the new drives. You will need to then enter and update the firmware on controllers and firmware on the drives.

    Now that I fully would you recommend to do is backup all the data of the entire table and reconfigure with a wide range of RAID. Then just break up with virtual disks rather than each has its own RAID level. You will see better performance when you have multiple disks in the disk, rather than having to group that he divided the way it is currently in place.

    Please let me know if you have any other questions and I'd be happy to help you.

  • Understand our server system

    Hi all

    I'm sorry for the long question, that it is. I wonder if someone can help me understand how our system of hard drives and servers are configured. Our main server is a Poweredge 2950 with five physical hard disks. Three in a Raid 5 configuration and the other two on Raid 1. The Raid 1 virtual disk size is 1.86 Tb. Which is what Managing Open Server Administrator said that the physical disks are two discs with each to 1.86.

    The size of Raid 5 is Go 930 and OMSA says it's three discs each 465 GB. Do I understand correctly that, in a Raid 5 configuration, three disks are required, but the size is only made up of two discs? If not, where did the another 465 GB?

    Thank you

    Magnus

    Nitman,

    That's right, Raid 5 requires at least 3 drives. With the reduction of the size, it's because of the parity. Raid 5 striped blocks and distributed parity. This means that parity is going through and is stored on all readers. Unlike Raid 3, who had completely separate players who stored parity. So, essentially when you set up the table, the parity will be an equal percentage % of the installed readers. If player 3, a 1/3 of the space is designated for parity. 4 discs 1/4 of each drive is used and so on. The reason for this is so that if any single drive has failed, and then the remaining disks have complete information on the remaining disks. What makes the redundant table for a single drive failure. Raid 1 is basically a mirror, where both discs have the same data, so if one fails, all the data are kept.

    Let me know if it helps.

    Hello, yesterday, we experienced a card failure hardware Raid on one of our servers Dell which runs the virtual Center. The raid card has been replaced but the blue screens of windows at startup upward, Dell currently studying, but I I wonder this incase question must be rebuilt.

    Is it easy or difficult is it to re - install Virtual Center, we currently have 3 x ESX hosts running can be re-imported in virtual Center etc.

    I have a backup of 2 databases, although they are a few weeks old nothing has changed from pools of resources, users, etc.

  • PERC H700 RAID 5, 3 disks, 1 Reporting failed and 1 predictive failure

    Hello:

    I have a PowerEdge T410 with a PERC H700, RAID 5 with 3 disks.  The controller reported a failed drive so I replaced the week last with a drive of new/refurbished.  Now only 1 week later it reported another drive has failed and the drive replaced as predictive failure.  Looks suspicious, i.e. I am doubting the controller card.

    I think updating the firmware of the controller first, but not sure if I should replace the faulty drive first, i.e. If updating the firmware could cause table failure.

    Also, if I install OpenManage on a virtual machine (host is ESXi 4.1), OM sees the controller?

    There is no method of recovery for RAID 0. You need to delete and recreate the table to replace the drive. If you need to store data, then you will need to back up before deleting the table.

  • H200 RAID 1 predicted failures

    Hi all

    I seem to have a strange problem with a RAID 1 array on a Dell R410 server. I urgently need some quick, if possible responses. It'd be so grateful.

    After the blue Server armored one Sunday evening I started to study and found that according to Dell OpenManage console drive 0 was a "predicted Failrure. The indicator light for drive 0 on the front of the server was also orange flashing, probably to indicate this problem. Also, when I checked my backup logs, I see actually between 3 and 4 reported CRC errors.

    I called Dell support and after have run me a DSET report and a Diagnostic test readers online they arranged for a replacement drive. We replaced the wrong disc, waited for the RAID rebuild and subsequently found to our amazement that Drive 1 has now reports a "predicted failure.

    I called Dell again, and they said that it could just be a coincidence. I thought that this is not an unreasonable thing to say, so we arranged to drive 1 to be replaced also. As you have guessed, we have replaced the Drive 1, waited for the RAID to rebuild and here, now drive 0 reports still "predicted failure.

    Then of course, we now know that something's wrong here. We thought that maybe he actually not related correctly as faulty disks, so we made an update of the BIOS on the server, but also updates to the Firmware on the iDRAC 6, as well as the controller of H200 himself. But it has not made a difference.

    Naturally I called Dell again, and they have now made arrangements for the controller RAID itself to be replaced, but also at least one drive (but maybe both, if necessary).

    My question is:
    (1) what could be the cause?
    (2) is the last solution offered by Dell, the best and the most logical next step to fix this, or could it be something else they did not examine replacing yet?
    (3) if the problem is caused by bad sectors, bad sectors can't jump / migrate from one disk to another, they can?
    I guess the worst thing that can happen is that whatever data resident in these bad sectors is now unreadable and unrecoverable, even from my backups? (since there now resynced to the two discs) Or are there other things to consider?

    Having never troubleshoot-performed a H200 heard, I can't tell what you'd find in a newspaper of controller - or if there even is (ex-SAS 6/iR have not one), but you probably have a range of corrupt or damaged.  He may have started with a drive bad - or even two - but if the table has a missing or damaged part on one disc, and he can't read this location even the other player to fix, it signals a problem.  There are two types of failures predicted - physical (drive reports it has a problem and is only a matter of time before, he is asked to do something, he can no longer do - disks will fail diagnosis) and logical (data in the table between the members is unavailable/irreconcilable and it's only a matter of time before a location is requested that the controller cannot provide specific information for causing read this disk failure - drives pass Diagnostics) (if healthy).

    Unfortunately, there is no 'solution' to this otherwise than to drop the table and re-create it.  Running periodic consistency checks can help to mitigate the consequences of these types of errors.

  • XPS9100 disk RAID failure

    One of the drives of 500 GB SATA 150 7200 RPM RAID is dead.   When starting, I get a message "ARRAY0" degraded and takes forever to start up.   Using the configuration of F2 at startup option SATA2 is not detected and SATA3 shows a hard drive.   I guess that SATA2 is the defective drive and HDD1 in the chassis.   What is the procedure to replace the drive with a new drive?

    What type of RAID?  If you have a table striped, RAID 0, you must save any data you want to stay on an external, remove the RAID (assuming you want to keep the player which is ok), replace the defective disk, create a new RAID 0 and perform a manual of your operating system and all applications that you want to use.

    If the RAID is RAID 1, a mirror, you can recover by replacing the disc which is a failure and the RAID ROM will rebuild the table using the right disk.

    Hello, hope you can help me with this.

    I have a desktop 710 PIXELS that has been giving me problems with raid. I completely formatted and installed windows vista 64 bit on it. Since then, I had to format it about 8 times since I bought it. every month or 2 months to the more, he starts sends problems in which everything slows down, then when I reboot, it stops the start and gives me errors of raid and windows vista gives me a little the message down to the right that says Raid access failure and when this happens, the computer hangs a little and everything that I spent mess up (obviously)

    I'm sure it's just a bad hard drive right? I already bought two identical hard disks and just waiting for them to get here so I can rebuild my Raid 1 with new hard disks. (Thank God I have everything backed up continuously)
