• You can develop a local raid set?

  I think to expand my local raid set on my esxi host 5.0 hp dl380? Currently 12 x 144 GB drives adding 4 x 144 GB more. Is it possible for me to add four additional disks in my Raid6 array?

  HP SmartArray controllers can usually reconfigure RAID if BBWC/FBWC is present and fully charged.

  After developing the RAID you may need to create a new logical volume for rather than developing the existing. VMware does not support them raise a datastore local VMFS from the GUI and you will have to do it manually from the command line, if you decide to increase the volume in any case (see for example http://communities.vmware.com/thread/335302).

  Please keep in mind, because of a driver problem, you can still be limited to a logical volume size of ~ 2 TB with some SmartArray controllers (although ESXi 5 supports up to 64 ~ to). See http://kb.vmware.com/kb/2006942

• SAN / RAID / vCenter number

  Interesting day today.

  We have a virtualized environment 5.1 mixed with light clients Sunray and Solaris 10. We have load-balanced Terminal servers and the virtual machine running the load balancing software was inadmissible, as the domain controller. In fact, 4 of our 10 guests were inadmissible. No one could connect so we have to try to determine what it was. First tried to get guests in the data center. After a lot of troubleshooting and a few reboots, we managed to get the hosts back in and operational things. Except that we found that a number of servers is grayed out and "inaccessible". Fortunately, we had backups VMDK so they have been restored and troubleshooting more has taken place.

  It seems that the data store containing the load balancer and the DC went offline at 03:30, and some time later re-presented as a disk empty. I re-read the HBA and the storage and then tried to readd and was the screen I've met:

  

  .. and after reviewing the events, I found this:

  

  Our SAN is a Fujitsu DX90 and I have a ticket open with Fujitsu but I reason to assume that this is a problem with the RAID on the SAN? I'm sure that's not CF related that we would see a host of other problems of connection. I followed this KB on the identification of records and trying to access the volume through SSH: http://goo.gl/QHJV1 - but, so far, I have managed to get the volume. Which leads me to believe that he is in fact a question RAID.

  My other question is the SAN are smart enough to do something if a RAID goes down? Should not be some sort of redundancy? And if not what you might find on a newer SAN?

  Or was it due to vCenter and something wrong at 03:30 thus wiping the RAID?

  Problem solved. I think that we had a reservation for SCSI.

  Restarted guests, out of the reserve of LUN on the interface graphics of SAN, reread and we're back in business.

• How can I remove a hard disk to the raid set default and replace it with a new one

  Last Friday apparently began one of my raid drives failing.

  As I said on this forum I started having continuous beep.

  I was finally able to get the raid works at a degraded level.  I ordered a replacement hard drive, that happened today.

  (In the meantime, I made twice daily backups of my work...)

  At any given time when I did the checked the browser interface, I have seen the message failed and degraded

  As I said, I was able to work this weekend on the degraded system.

  This morning I had the new tone and made the rescue and now I use a "full raid" without the advice that a raid was 'free '.

  In all cases, the new drive arrived today.

  Should what precautions I take to integrate the new drive in the raid system.

  I have an OS disk

  and raid 4 TB drives.   One needs to be replaced with the new one I get today.

  Thank you

  Rowby,

  You currently have your background priority set to 20% IIRC, so it will take time to rebuild, but probably a lot less than 24 hours as for new construction. Even with 20% defined, I guess that it will be done in less than 12 hours, but you can set the background priority to 50% and it will be much faster at the expense of access to your raid. Reconstruction of the background is designed to give you access to all your data files and to continue the work, while the data is being rebuilt. You can continue your work, so if it takes 8 or 12 hours to find the full data intergrity isn't all that relevant. Your aura a functional slower than with a raid reaction complete, but has more speed than a single disk.

• ASM vs San raid which to adopt

  Hello
  
  We have a system using ASM and San drive. San has a hardware raid, while the DSO has also do the same thing. Because according to my understand its function. Strip and any mirror. Do you think we have several raids in the system and we should disable hardware raid. Also I thing hardware raid is raid 4. Please correct me if I'm wrong
  
  concerning
  Nick

  RAID 1 + 0 or 0 + 1 is an implementation of striping and mirroring.
  RAID 5 is an implementation of aggregation by band with parity (where the parity strip is scattered between the discs, with RAID 4 parity stripes are on specific disks)
  See: http://www.baarf.com

  Please, mind, than the baarf Web site focuses on the decrease in performance (writing) of the use of RAID levels with parity. Even with the SAN, it is still quite true. (it is inherent on the way to parity is implemented)

  ASM normal redundancy is essentially a mirror application. The implementation of normal redundancy ASM subtly different way works mirrored RAID.

  This means having RAID 1 + 0 / 1 + 0 on SAN level is a way of mirroring, and having normal redundancy ASM is another way to have copies mirror blocks, which would mean that having RAID mirroring on the normal SAN and level of redundancy at the ASM level means you have 4 copies on the same storage box.

  So I would say that there is little benefit to have normal redundancy ASM on top a stripeset mirrored.

  As an adviser what to do: most ASM implementations use external redundancy, which means the redundancy of the San is used. I think it makes sense.
  With the help of normal redundancy makes sense when you use local drives (non-RAID), or when having multiple SAN.

• Setting up RAID 0 onboard

  I used the Intel Matrix Storage Manager on my motherboard ASUS to set up 2 of my 5 drives in RAID 0 and now I can't start.  The system disk is not part of the RAID set.  I can boot Knoppix and always see the data on the system drive.  At first I thought I might be able to use the repair function on the Windows 7 installation DVD to rewrite the boot sector, but I noticed that the BIOS lists not all readers when I go to the boot selection sequence so I doubt that would do any good.  Is it possible to set up a RAID Motherboard after Windows is installed, or I'll have to reinstall everything again?

  Roy

  My problem with the BIOS to not booting from a hard drive has mysteriously disappeared.  I was doing notes on all my changes to the BIOS before I made a Clear CMOS for everything reset, and when I got to the boot order, the hard drives were back to the list.  I chose, saved, restarted, and everything goes well (including RAID).  The only thing I can understand is maybe save the BIOS (F10) and restart was not actually save everything and it took a full power down to do it.

• Virtual disk on an iscsi SAN

  I have a question about virtual disks and how they actually read and wrote on the physical disks on a San.   Lets say I have the Exchange virtual server and a virtual SQL Server on the same RAID set on the SAN.  As you know, Exchange writes on the disc at random while MS SQL server writes sequentially.  Each app just write randomly and successively on their respective virtual disk?  If so, VMware wrote how physical disk with regard to how the application has written to the virtual disk?  For example, if Exchange writes randomly on the disc, which is technically the virtual disk on the ESX host file, VMware writes the changes to virtual disk random file on the physical disk?

  It depends on your performance needs - usually it's a good practice (virtualized or not) in order to isolate the workloads that shouldn't be able to influence the other.

  So, you can choose to create small groups of raid for the individual applications.  This has the advantage of better insulation, but at the cost of reduced performance for this application (and reduced the efficiency of storage capacity).

  It depends on your business needs.  If your SQL server server have been got nutso and eats all your IOPS / s, it would be OK that the Exchange has become terribly slow until you figured it out?  If so, then of course keep 1 large group.  If this isn't the case, then it split and bite the bullet on the cost.

• Best Senario distributed virtual machine between SAN LUNS and replication fail over Senario

  What the best best Senario for the installation of virtual machines on Big LUN or each VM on LUNS dedicated:

  We planninig to implement 70 virtual machines on Esx 3.5 servers with replication LUN usisng CA of HP 7.

  using 4 Big 800 GB data store on SAN RAID 5 Lun (each LUN will be contains 16 VMS)? or each VM will be deployed in separate small LUN 50 GB data store on SAN, RAID 5 and that this effect on the failure during the procedure on the DR Site if we choose BIG LUNs, also if this virtual machine includes 3 disks (store them on each disk on the different data store or the same data store)

  Thank you

  Remember that the virtual machine is a set of files and these files directly in your data store.  If you have a large store of data with multiple virtual machines, you must replicate the full data on the alternative site store in order to get to that data.  You can't really use greater SAN replication for just the simple vm in a data store.  SAN replication is not really aware of what is stored on it, she replied just blocks he knows.  You can copy the vm files individually as well, but it's more than a copy and not replication.  Otherwise, if you are concerned about vs some other vm, then using a small LUN would work better for you, or warehouses of data at multiple levels allows you to replicate the vm that are important to you and put the rest in a larger data store.

  FCIP/FC/IP doesn't really matter.  Until a table can talk to each other, you're fine.  Our secondary site is hundreds of miles away, and replicate us very well during the period of INQUIRY, from one table to the other.

  Yes, without SRM, you will need to manually register a virtual machine at the time, or write a script to work through all the.

• synchronization of the RAIDs at 2 different locations

  I recently started to work in 2 different places and must find a way to keep my 15 TB + of the continually changing and growing data (in RAID 0 training photoshop files) practice at both locations at any time.

  My best idea so far is to get a 15 TB portable working drive that I bring with me back and then continue to a RAID of TIME stationary MACHINE at each location who save permanently this portable work in car...

  If anyone has a better idea, please advise.

  Keep your valuable data on a striped RAID is dangerous. Sometimes interlaced RAID adds speed, but in case of disk failure, is likely to result in a total loss of all data without hope of a partial recovery.

  Put data of Time Machine on a mirrored RAID is a loss of readers.

  Time Machine can alternate automatically readers to keep two (or more) independent backup series. Just add the second drive and it automatically alternates.

  As always, you can use AppleRAID or an external RAID enclosure for the construction of a concatenated RAID set that resembles a drive for Mac OS X.

• Qosmio G20: Question on the status of RAID

  Small question. I want to determine if the RAID is completely disabled on my G20 (2 x 100 GB hard drives).

  When I reinstalled the operating system from the recovery disks in the RAID set up, I chose the option of two independent hard drives so they now drive C & D with Mac on C and D data on.

  If I go to the RAID console, it says "Can not get status", so I guess that the RAID is completely disabled but I wanted to just make sure.

  Thank you.

  Yes, you are right. You need at least 2 disks for a raid configuration to choose two independent disks made (off since raid), and your raid is not enabled. Good day.

  HOW TO SOLVE THE PROBLEM?

  Hello

  Ok. You have changed the RAID settings in the BIOS.
  In my opinion, you can use the CD of restoration with the default RAID settings in the BIOS.
  I mean that the RAID driver on the recovery cd was preinstalled and you have changed the settings RAID in the BIOS for the recovery CD did not work properly.

  Do not mix the original Windows CD from Microsoft with the recovery CD. The CD-ROM of Microsoft the RAID driver is not, but on the recovery CD.

  I checked the Qosmio manual I found on the Toshiba site.
  If you want to install the original WinXP you must safe the RAID driver on the floppy.
  In addition the in table settings BIOS RAID, make sure that the built-in HDD is set to 1RAID-0.

  The RAID in the BIOS configuration settings are described as follows:
  JBOD - parameters without RAID, Windows cannot be installed on this drive except by using the recovery CD/DVDs.
  1RAID-0 - compatible set RAID. Windows can be installed on the drive
  2RAID-0 - 0 for 2 hard drives RAID set
  RAID 1 -RAID-1 set for 2 hard drives (current only)
  UNKNOW - State RAID except the State and settings (State only) above
  No. Drive - no hard drive connected

  If you accept the settings you must type a string: 1,2,3,4 then enter. At the end you must save all change in the BIOS.

  You have suggested that you have the German language. If you want to read the manual in English you can download it from the site.

• 2008 mac Pro Apple Raid card problems, help!

  Hello, I have a mac pro 2008 with a raid set up. I want to get rid of all old raid together upwards and instead put a new ssd in the first Bay. The computer cannot read it because I think that it is always configured as a raid. Does anyone know how to make the available drive bays to new readers? You're help would be highly appreciated. I want to take the Apple Raid card so I can have an additional PCI port and I also want to get out the discs four raid. Just so I can put in a single ssd! Thank you very much.

  When you remove the Apple RAID card, readers who were searched will be unreadable. You need to make backups before time, because there is no way known to them read differently.

  There is a data cable, called the iPass cable connected to the motherboard to the RAID card. You must remove this cable when you remove the RAID card and reconnect the plug corresponding on the motherboard. Once you do this, you get four bays returned as SATA bays and can install any drives that you like. The problem with a lot of SSDS is that they are 2.5-inch form factor drives and may not fit on a standard sled. Users have used an IcyDock (in the 2008 version and earlier versions) or the newer technology adaptadrive:

• MOBO battery died, replaced, went sata/raid drive.

  The computer has win - xp, 32-bit. It had been updated. At sp3. Asus P5wd2 mobo. The system worked very well. The C - mos battery died then. I replaced it. Now, there is only the C:\ drive and a drive partition L:\. It is therefore more H:\ by car (at home). The drive H:\ was the raid set before the battery is out. I don't know how to get it back. When xp came back upward, it is requested to install (recommended) some readers of the unit, so I did. The drive did not return after the reboot.

  I went into the BIOS, go down to 'IDE CONGIGURATION'--> Select "RAID" not "SATA" Press F10, Save and Exit, re - start - found the player.

  Don't go in the RAID itself - just the BIOS!

  Hello

  How did you come to the conclusion that your motherboard is toast?

  If you disconnect the SATA drive connectors hard and any other external device except a keyboard and video output and then it turns on, what is she doing?

  You must have a motherboard that was identical in all respects to recover a RAID set or pass (as you now now) crazy amounts of $$. Even with an identical motherboard (storage controller identical Intel and chipset) the RAID set may not be recoverable. You can not move readers to another motherboard and wait for everything to be good again. RAID is a special case and it simply does not work out like that.  If the RAID set has been the RAID 0 then the data are spread over two discs. This means no redundancy. When a drive goes down your data has disappeared. If the drive was RAID 1, then replace the failed disk can be done. The RAID set can be re-created by the Intel Matrix storage software solution.

  Here is a Wikipedia article that has a reasonable explanation of the many types of RAID and their advantages and disadvantages.  The acronym RAID means redundant inexpensive disk array. Redundancy in Information technology is the "repetition of critical elements" or functions of a system with the intent to increase the reliability of the system, usually in the case of a backup or fail-safe.
