• Suggested Drive setup for new h8 - 1360t with SSD and Raid-1 array

  All,

  I need some advice on how to configure the drives in my new system (waiting for construction and delivery, sigh).

  I bought a plan to replace the 1 TB drive with a new drive SSD that I start from and H8 - 1360T (Win 7 Pro).

  I also have a Raid-1 array in an old HP 4999 T system (Vista) disks Western Digital Caviar Black 2x2TB

  By looking at the motherboard plug appear to be only SATA0/1 6 GB/s, the others are 3GBPS.

  http://support.HP.com/us-en/document/c03132942

  I was a little surprised by that and need some advice.

  1. If I put the SSD on SATA0 or SATA1, the quickest way?

  2 or do I put the drives Raid-1 array and move the SSD to path of 3 Gbps?

  I think this last (option 2), but wanted to get your entry in case missed me something.

  Thank you

  Joel

  Ruette,

  Thanks for your comments. Looks like I should start with Option 1 as a better starting point.

• Factory restore / Boot Order RAID 0 array?

  I have a 'mobile 'current enforcement office (laptop) XP Pro SP2 with dual hard drives in a RAID 0 array.  For various reasons, I want to put the machine in its factory out-of-the-box condition using discs of recovery/restoration of the manufacturer (essentially the application of Norton Ghost). I did my due diligence regarding the restoration of the machine and 'reconstruction' from there, but the machine does not start on boot from the restore disc CD.  I do not venture into the BIOS often... the existing boot priority order is as follows:

  1. USB FDC:

  2 PCISCSI: FTTX Ary1

  3 IDEO_M: QSI CD-RW/DVD-ROM

  4 IDEO_S: _NEC DVD + /-RW

  5. PCI LAN:

  6.

  7 etc.

  I don't have a built-in floppy drive. I want the machine to start from #3 (my first optical drive).  In the order of precedence of the BIOS Boot, I simply move #3 to the #1 or #2 position?  Will be other items then simply drop into their existing order?

  I do not know how does RAID 0 of the table is on the boot order selection, but I don't want to spoil anything.  I appreciate your help and your expertise.

  Hi Aravaipa,

  · On what CD drive you insert the disc?

  · The operating system was preinstalled on the computer?

  · If so, what the number and model of the computer?

  · If it was custom build provide the serial number and model of the motherboard?

  · Have you have saved data on the computer?

  I suggest you to back up data before performing the procedure below:

  1. If the computer is preinstalled on RAID 0 configuration then you might need to break the Raid by changing the variable speed drive (ATA controller) to Normal or IDE

  2. as you have two CD/make ROM DVD readers like the first and the second in the boot sequence and make the method of trial and error to see what DVD Rom detects the recovery disk

  Note: Change to the BIOS/complementary metal oxide semiconductor (CMOS) settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk. You can contact the manufacturer of the computer for better assistance.

• RAID 5 array on PERC6 / I offline

  OK, so we have a 2970 with a PERC6/i. 5 disks in a RAID 5 array and a hot spare. I apparently lost two readers today, one failed and the other started showing as a foreign config. I erased the foreign config and I replaced the drive, but now on my table, I show 3 disks and 2 marked pitches "missing." How can I make this table back online and ready to go without deletion and creation of a new VD? Thanks in advance...

  IMPORT

  Used ONLY when the array is offline (non-functional/failed). If you have a 3-drive RAID 5 and two disks are foreign (or a stranger, a failure or missing), RAID 5 is dead and off line. You must import it in this case. If you replace a drive has failed/foreigners with a new and a new is marked as foreign and you import, you will corrupt your data.

  CLAIRE

  Used ONLY when the table is online (upward and running, functional). If you have a 3-drive RAID 5 and a single drive foreign shows (which means that the disc is also offline), you must DELETE it (if it is an original or a replacement drive), and then assigned as a hot spare.

  In general, once you clear the foreign configuration, you do not get a second chance - the disc is in a ready state.

• RAID 1 array degraded; no option to rebuild

  I have a PowerEdge T110 server with a PERC S100 RAID controller (firmware / RAID of 'false').  Unfortunately, I had a little accident tonight while I was working on this machine.  In trying to clean up a mess of cable, I accidentally yanked on the wrong cable and disconnected the power supply of the server.

  When the server has been run through POST, he paused and said the RAID 1 array was degraded.  Entering the S100 configuration, it tells me that unit 0 is degraded, and the other is fine.  The server starts very well.

  I opened the OpenManage utility that displays the status of the Ramdisk to deteriorate as well.  However, despite the poster the State as being degraded, absolutely nowhere no it lists all option to rebuild the table.  I can't even check the consistency.  Under the drop-down list for 'tasks', the only available options are:

  1. Delete
  2. Having-right/remove the dedicated hot spare assignment
  3. Change of name

  That's all.  Of course, I don't want to do any of these.  The BIOS configuration utility seems also unnecessary.  Although it lists the specific physical drive that is deteriorating, I see no option to rebuild the coherence of the table.  Because the physical disk has failed and is not actually damaged, I don't need or want to replace it.

  So, why everything isn't rebuild option listed, and how can I rebuild this table without deleting all of the volume and restore a backup?

  I tried swapping cables, and while he was smart enough to realize that the disk has just moved, it has not affected the degraded disk.

  I decided to do bankruptcy and just remove the degraded and 'clean' drive by using DiskPart.  That has worked, and Windows 7 shows the drive as "not initialized".  I put back it in the server, and it has been recorded as being non RAID... was not even as 'new '.  Basically, it was like its own volume automatically.

  I kept starting in Windows Server to verify that I have screwed something up to put my nerves at ease.  Windows starts, I went in the virtual disks of OpenManage section and saw that the (rather old) 'new' drive appeared.  So, I chose "delete" in the list of available jobs.  He deleted successfully, disappearing from the list of virtual disks.

  At this point, I thought I could go ahead and assign a spare drive dedicated to the array degraded since the tasks available.  Nope. No disks available. What?

  Panic now, I went in the "physical disk" section of OpenManage, and he was there with his status as a 'ready' (opposite to 'online').  The title of his available tasks, it was 'global hot spare assignment. "  I did that, and the status of the RAID battery under 'virtual disks' changed to 'reconstruction '.

  [ADMIN NOTE: profanity removed by TOU], why was it so difficult?

  During the time I spent writing this, its reconstruction progress has reached 4%.  I'll update on the State when it is finished.

  EDIT: Everything worked successfully.  Reconstruction finished after a few hours and the RAID volume is re-reading in good health.

• Degraded RAID 1 array: PowerEdge 2800

  Hello to everyone. I hope someone can shed some light on this unusual situation.

  I have a PowerEdge 2800, which must be replaced before May this year, this is a great server and done an excellent job over the past 7 years.

  OK for the problem; The server administrator has been a failure on 0:0

  In the server, we have:

  0: Maxtor 36 GB 15 k 0 0:1 Fujitsu 73 GB 15 k something 1:2... 1:3 something...

  So, I jumped 0:0 and the server worked great with a range of gradations, and 15 seconds I inserted back to the PE2800. After about 45 minutes the RAID 1 array has been rebuilt, but it still says expected failure. So I thought that better order some new readers - I received today; 2 x 146 GB 15 k Seagate Cheetah.

  OK, so I jumped 0:0 drive and inserted one of the 146 GB Cheetah and the server crashed - wouldn't boot at all and gave me an error stating that the logical drive failed.

  Thus, in the PERC4i BIOS, I forced drive 0:1 online and the server is now back operational but with a range of gradations.

  So that's where I am, what choice do I have?

  Insert the old disk with a predicted failure, leave it alone or try the 146 GB Cheetah. I don't really want to do an any of them, but I will order another 73 GB Fujitsu in the meantime.

  I want to know is why the server crash after having inserted the cheetah disc? I traded to many-a-time pluggable hard drives in the past in several dell breaks and never experienced anything like this.

  Degraded running, any response would be massively appreciated.

  Thank you very much.

  "So, I'm now to square, where I have a RAID1 system with a disk failure planned.  What would you do from here on? »

  Another thing that many people do not know is with a disk of pf, should it be forced offline before replacing, if not the FP flag can be assigned to the new drive (until a real "rescan" is performed) and can result in strange behavior (the controller is more sensitive to potential readers of pf failure).

  "Common sense says I can't mix-match 10 k / 15 k TPM!

  You CAN / layout speeds and/or sizes (there's nothing wrong with him "technically"), but in real-world scenarios, you would ever want to mix speeds (depending on the configuration, it degrade the speed of the whole picture).  One thing you can't do is mix U320 SCSI U160 readers on a bottom of basket/controller.

  "What would you do from here on?

  I guess from here depends on what you feel more comfortable making.  There is a chance that the pf reader works fine until you are finished with the server (or until you can get another replacement - if you feel another replacement would be better than those you currently have), even if it might cause additional problems if his condition deteriorates.  There is a chance it could happen again if you try to replace it, but I think it's unlikely to happen.  If it was me (and it is important to remember that this isn't :)), I force disk 0 offline and replace "hot" by the other 146 GB drive.  Another thing you could do, who feel probably less risky, is simply to insert the disc of 146 GB in an open slot, assign as a relief, then force offline disk 0, which results in a regeneration start automatically with disk 0.

• 4.0, ESXi and 3Ware 9650SE Raid 10 array - now what?

  Hello-

  I installed ESXi 4.0 on a new server with the above mentioned RAID 10 array and that you have installed vSphere Client on a separate computer. Under storage cards, I see the following:

  Mobo is a supermicro X8DAH + controller 3Ware is a 9650SE SATA 8LPML (8 ports) with 4 disks preconfigure RAID 10

  How can I get ESXi to see table so I can start installing VM?

  Also, leading me to http://kb.lsi.com/KnowledgebaseArticle15548.aspx

  Yes, this link seems to have enough detailed instructions on how to install the specific driver under ESX and ESXi.

  When I run Setup ESXi 4.0 DVD, there no option anywhere to load additional drivers?

  According to the article, your RAID device can only serve as secondary storage under ESXi.    If this is the case, I would be first to install ESXi to a small local SATA or USB.  After the initial installation, you can then follow the instructions in the article linked to download/install the driver for your RAID controller.  Then you can use your RAID array to store your guests on.

• PERC H330 and Raid 5, try adding another SATA drive raid 5 array

  Hi all

  I have one server PowerEdge T330 with 8 slots of disc and have currently 3 SATA drives running a raid 5 configuration.  I have a virtual disk configured for Raid (must).

  The operating system recognizes the disk and is able to use the resources...

  My desire is to add another hard drive to the table (hard disks of the same size, same brand, etc.) with 4 disks without losing any data.

  I looked in the settings of the iDrac and the only adjustment was to add the new disk as a global hot spare or a hot spare dedicated to the virtual drive.

  I also looked in the BIOS and do not see a way to add the new drive.

  Does anyone know how to increase capacity?  I can blow the virtual drive if necessary and start over without problem.  I intend to gradually accomplish this Act until adding 8 disks. (5 times).

  Help!

  Hello.

  Management controllers RAID and tables is not made in the BIOS iDRAC or systems. For the management of the RAID (virtual disks) arrays, you have OpenManage Server Administrator (OMSA). If not installed, see the link: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=TK61C once installed, go to-> Storage->-> H330 PERC controllers-> virtual disk--> sub tasks available-> select reconfigure and run-> then check a box to add the fourth disk on the next page. Follow the prompts and allows you to extend your range of RAID 5.

• Upgrade the disks in RAID 6 array: what is the best

  I have a Dell PowerEdge 2900 running Windows Server 2008 R2 and 6 x 75 GB 10K SAS drives.  PERC 6 / i controller RAID 6 with 5 drives + HS 1 (total 6 discs)

  I have 6 x 300 GB 10K SAS drives ready to trade.

  I read everything I can on hot swapping etc and what I can't find is any method to close the front discs actually pulling them.  Supposed to be via Computer Manager-> storage but not here?

  Restarted, Ctrl + R, in the controller BIOS, nothing there either.

  I have therefore 2 options:

  (1) go for it, just pull up a disc and put in a new and let them rebuild.  Repeat x 5

  (2) stop, change the music, etc.  I don't like to stop a perfectly functional server...

  Looks like #1 would be better, but without the stop disk option I'm not sure...

  Then there is the whole operation in general.  It is best to:

  (1) hot-swap & rebuild

  (2) make a backup to disk image, on all readers of a sudden and restore?

  Looks like #2 would be better... but I don't still need to re - install the software on the array of naked?

  Hello

  budcarlson

  I read everything I can on hot swapping etc and what I can't find is any method to close the front discs actually pulling them.  Supposed to be via Computer Manager-> storage but not here?

  The operating system has no control on the disks. The drives are controlled by the PERC. You must use either a software that allows the management of PERC as OpenManage Server Administrator or boot directly on THE controller's BIOS.

  You should have an option available for the physical disks offline before removing a table. Which will allow you to remove a disc without causing data corruption.

  The best practices and the method supported is to back up the data, create a new RAID array with new drives, reinstall, and then restore the backup.

  Hot swapping and reconstruction are the best way to do this, but the simplest is not the best way. If you choose to rebuild and hot-swappable, you will also need either to create a new RAID array (sliced table) to use the new space or change the markup for the table.

  You should be able to just replace the drive and rebuild automatically.  That said, before you do anything, make sure that your system is fully backed up.  RAID is redundancy - NOT a substitute for a backup current, functional, verified.

• PowerEdge 2850 - Perc 4e/Di - status of the RAID-1 array

  I'm trying to give a sense of the info in OMSA 2.1.0 for a RAID 1 virtual disk on a server Poweredge 2850 + Perc 4e/Di.   Array disk 0:0 died at an unknown point in the past.  Info OMSA before replacing the drive:

  

  

  We have added another 0:0 drive, he rebuilt successfully automatically and this is the current info:

  

  

  

  So the State of the virtual disk RAID-1 is is more "degraded" and yet it is still showing only 0:1 Hitachi disk array and not the new 0:0 Seagate.  How this should be interpreted?  We also have another virtual disk raid 10 on this same server with discs model even who had also a drive down and replace this trained player the new Seagate drive not appearing in the table of Raid-10 list as expected.  the difference was that the Raid array-10, the original disk was displayed in OMSA as 'impossible', while on RAID-1 above, no other player has been listed.

  It should show the other disk.  A few things to try:

  • Refresh the screen VD
  • Closing/re-open OMSA
  • Stop/re-start services OMSA (DSM)
  • Clear the ESM/Hardware log in OMSA
  • Restart the server
  • Updating system firmware (BIOS, ESM, PERC (first pilot), HARD drive)

  All the foregoing may work, but it's probably caused by obsolete OMSA and/or firmware/drivers.

• Economic construction - RAID and Fans Questions

  I am considering the following construction to an editing room (badly used as reference guide). I don't know how many fans, if necessary, I have to buy. The case comes with 4 x 140 mm fans, and I don't mean to overclock the CPU immediately, but plans of OC'ing to 4.4 GHz in the near future.

  Also, would a RAID 0 configuration agree with 4 hard drives? The disc only I'd be willing to lose risk would be the drive of files/export output. So, any combination of table 2 disk could lead to catastrophic data loss. 'Economic version' of harm recommends raid 0 for a 5 hard drive configuration, so it seems that 5 hard drives is a sine qua non for RAID 0. Any comments would be helpful I have realized recently that you can do with RAID configurations. Thanks in advance.

  I'm not familiar with the case and do not know the air flow. If you are worried about the time, you can consider a larger case allowing a better air circulation. If you selected now is not very wide, so adding the fans on the side can be difficult due to the height of the fans and the height of the video card. The case has it air balanced, positive or negative? Dust filters are used on suction fans? There are so many questions, which make impossible the respondent.

  When you have generated your system, measure the different temperatures at stock speed. If they are acceptable, even under a load of stress, it shows that the coolant is OK. Now overclock and do the same test. If temperatures rise to say more than 10 degrees C, then you have additional fans and you have to study the airflow more closely.

• Migration to a RAID 0 array

  I'm looking to use the drives in my current RAID array of desktop computers (see my signature) inside my next House construction. It would be just a whole case of formatting of the RAID array and move the hard drives in the new office and placing them in the same SATA ports?

  Or it would imply the setting up the RAID array again?

  
  

• W520 - RAID / hard drive questions

  Before I discovered, I received a replacement W520, I bought an SSD 128 GB to Lenovo (a student discount, it was not too bad). I bought it because it's a SATA II interface, what my current W510 can support. But now that I'm a W520, that supports SATA III I should probably send the SSD back and get something else, right?

  In addition, I don't know much about RAID, but I won't need to use a secondary HDD in my ultrabay slot I'm going? What about the mSATA... If I have three drives in storage at the same time, will that require RAID?

  Regarding the 128 GB SSD, which really depends on what you paid, return the shipping charges and restocking fees.  I would never buy a SSD from lenovo.com.  You don't look at newegg.com?

  About the RAID, no doubt whatever.  Unless you had it on your W510, W520 replace will not have it.  RAID is not necessary to use on three storage devices in the W520.
