PowerEdge R510 - expand RAID5 with additional disks

Hello

I have an ESX5 VMWare hypervisor running of PE R510 (embedded) on SDs in the mirror.  We currently have SAS 5 x 146 GB drives in a RAID5 configuration that provides approximately 1.6 gross TB of storage for the VMFS data store.

I'm trying to understand whether it is possible to add additional disks to this configuration RAID5, so expand the virtual disk, without the need to destroy/loose data in place?  If so, what steps would be to do this?

Thank you

Chris

Yes, it's called Online Capacity Expansion.  You can reconfigure your 5 RAID 5 disks to include more records by adding them to the table.  It is non-destructive and can be done online.  You can use the service reconfigures the software OpenManage for do this, either by adding the VIB ESX or boot from a disk Live OMSA.

Once you have added the records in the table, you need to resize partitions in ESX.  Also, I think that 5 + uses default TPG, but keep in mind that if it is not the case, then your picture will be limited by ESX 2 TB of usable space.  This would likely only (potentially) be a problem if you have gone to some other version 5.x.

  • PowerEdge R530 - expand Raid 5 by adding disks

    I have a R530 PowerEdge with Perc H330 mini with currently 3, 300GB sas hard drives configured as a virtual disk.  VMWare ESXi 6 is installed with a couple of running virtual machines and I'm out of room.  I installed a Supplement 3 of the exact same hard drives and wants to expand the virtual disk with 2 of the discs and the other as a spare drive.  Using OMSA I put the hot spare, however before you reconfigure the virtual disk, let me know if I'm doing it correctly.

    Within the OMSA.

    (1) select my virtual drive, select "reconfigure" and run

    (2) (check two additional disks to add to the virtual disk, press to continue (step 1 of 3))

    (3) raid level default switch to Raid-0 for RAID-5 current and desired and press continue (step 2 of 3)

    (4) check the settings and click Finish (step 3 of 3)

    I can do this without closing to the right of my VM?  This will not destroy my data this?  I have backup, but would prefer not to have to restore.

    Thanks to confirm or point out my mistakes.

    Yes, it is intended to make online and is non-destructive.

  • Expanding RAID5 on PowerEdge R720

    Hi all, I have a R720 Poweredge server configured with 2 virtual disks, one for the operating system (RAID 1) and one for the data (RAID5 with 3 drives 1 TB each). I plan on expansion of raid5 with another disc.

    The drive has been added and is currently recognized by the OMSA as loan. From what I understand now, I need only to use the task some "reconfigure" on the VFD of the data.

    I have only a few doubts:
    1 - is this 'reconfigure' task is to clear all data?
    2 - can be performend online or I need to bring down the system? Is the reboot needed?

    Thanks for your help

    Hello.

    gnegnegne
    I have only a few doubts:
    1 - is this 'reconfigure' task is to clear all data?

    Reconfiguration of a table does not erase existing data; It influences only the performance disk until the reconfiguration operation.

    gnegnegne
    2 - can be performed online or I need to bring down the system? Is the reboot needed?

    Of reconfiguration is done only online and even once the operation is completed, no reboot is necessary.

  • Impossible to create a RAID5 with Advanced Wizard

    I have an MD1000 attached to a Poweredge 2900 (Windows 2003 Std R2 SP2) via a PERC 6/e. I am trying to create a table of 8 drives RAID5 physical usng OpenManage advanced drive the virtual assistant. I am able to execue the first of two steps, selecting the RAID level, and then all 8 drvies. When I get to the third stage, where I should be able to enter a table name, size, etc..., I rather just get a white screen.

    I tried to create other levels of table as (6, 10, 60) using the Advanced Wizard and the same thing happens. When I use the wizard Express, there is no problem, but of course I can't create a disc of 8 RAID5 with the express.

    Anyone know why this is happening? The contoller firmware is 6.3.0 - 0001. All the disks are SAS 146 GB 15 K Seagate Cheetah 10.

    Thanks in advance.

    I suggest trying a different browser or play with the security settings in your current browser. The blank page looks that the browser does not display, which can lead to a different browser.

  • PowerEdge 2900 (and 2950) with PERC 5i - extend Raid 5

    Hello

    I have a Dell (PowerEdge 2900) server with a Raid PERC 5i (with BBWC) controller and 4 SATA drives installed (a virtual disk Raid 5, Windows 2008).

    Now I have an extra drive (same capacity, same speed) and installed on the server.

    I tried to expand the existing virtual disk (and the disk group) with the new physical disk drive in the BIOS of the controller and openmanage server administrator (managed node) running on windows.

    But it is not possible to do with this Raid Cntrl?

    Is there a way to do this without loss of data and maintenance of raid 5 redundancy?

    The same procedure I need to do on a PE2950 (PERC5i)

    Thank you and best regards,

    loop11

    What have you tried exactly, and what has happened or what have you seen?  You did not mention anything that leads me to believe that you tried this in the right place :)

    The PERC 5 / I can do without a doubt:

    With the disc, go to OMSA, PERC, case/bottom of basket, storage, physical disks and make sure your drive shows ready.

    If ready, go to the OMSA, storage, PERC, virtual disks, select Reconfigure in the drop down menu to your RAID 5, follow the wizard to add the disk.

    If the record shows the foreign, go to the OMSA, storage, PERC, Information/Configuration (link at the top of the page), click on foreign/clear in the dropdown menu, then follow the directions above.

    Hello.

    I am trying to use one of the four usb ports on a Dell PowerEdge R510 inside an ESXi 4.1.0 260247 host for a XP Prof invited. I have the following PCI devices:

    http://communities.vmware.com/servlet/JiveServlet/downloadImage/10539/esxi41.jpg

    With each of the devices ID 00:1 a. 0 00: 1 d: 3 comments XP correctly will not start. When I attach the 00:1d.7 device boots comments, but then there is a problem with the device driver. I tried the chipset drivers for W2003 from dell (http://support.euro.dell.com/support/downloads/download.aspx?c=de & cs = debsdt1 & l = a & s = bsd & releaseid = R269378 & SystemID = PWE_R510 & servicetag = & os = WNET & osl = GE & deviceid = 17195 & devlib = 0 & typecnt = 0 & vercnt = 2 & catid = 1 & impid =-1 & formatcnt = 0 & libid = 27 & typeid =-1 & dateid =-1 & formatid =-1 & source =-1 & 396483 = starts) , but no luck.

    I know that there is now a direct usb support in ESXi 4.1, but my usb device is not supported through this new feature.

    In addition, I'm looking for a PCI Express RS232 serial card that works on this server equipped with passthrough for a XP guest.

    Thank you

    Michael

    Try to ignore this ridiculous list, it's a bad joke for devices on the external bus like SCSI and USB.

    I've successfully used the USB feature in 4.1 for a device not on the list (in fact, he was a device of type modem/serial port), more precisely a key entropy of Simtec.

    So anyway, try your device with the USB function before mingling with the much more fragile PCI passthrough feature.

    Additional CPU: Intel Xeon X 5675 (3.06 GHz, 6 C, 12 Mb cache)

    64 GB of RAM by 2CPU (LV double rank of 8 x 8 GB RDIMMS) 1333 MHz

    We want to upgrade servers with 128 GB of RAM.

    What is the most appropriate way to do it?

    Can I order 8 modules with 16 GB of RAM and replace?

    Thanks in advance for your help.

    Enzorik,

    You can order and use the 16 GB DIMMs in the R510. You can see the directives of the population by proc on page 117 of the guide, located here. Before the memory upgrade, however, you must be certain that you have the server to update BIOS, Drac, lifecycle controllerand Raid Controller. This is to ensure that the server remains stable.

    Let me know if that answers your question.

    can I burn the recoery CD?

    Read the General information below on the recovery of Partitions and recovery discs and contact the manufacturer of your computer.

    How to get Vista recovery Media and/or to use the Vista recovery Partition on your computer.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    You can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

    They will tell you how to do this.

    Every computer manufacturer has their way of doing recovery disk/s.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  • Dell poweredge R510 128 GB of RAM

    Hello.

    I want to upgrade my Dell PowerEdge R510 with 128 GB of RAM.

    Can I use the 16 GB of RAM x 8 double row? Like this a broken link has been removed from this post by Dell>

    Or I need memory command quad rank for my upgrade? And if so, Dell provides this type of RAM?

    Thanks in advance.

    Enzorik,

    The 16 GB x 8 DIMM you mentioned here

    are indeed certified replacements for the R510. They would be the DIMMs to use.

    I hope this helps.

  • How to expand your virtual hard disk while host hard disk space is not enough?

    People,

    Hello. I use VM Player 3. My host computer is Windows 7 and VM is Oracle Linux 5. I need to expand the virtual hard drive Oracle Linux 5 from 100 GB to 150 GB. When I click on VM > Settings > hard drive > utilities > expands...

    The error message:

    There is not enough space on the file system for the selected operation.

    To after my understanding, we have enough room to store the VHD original more expanded VHD.

    This means that the free space on the host needs to be 100 GB + 150 = 250 GB

    The total size of the hard disk of the Windows 7 host is 284 GB. The VM already occupies 100 GB of 284 GB. The maximum free space is 184 GB less space and boot OS. This means that I can't develop the 100 GB to 150 GB VHD.

    But I have to expand the virtual hard disk! I don't know if there are other ways to expand the virtual hard disk.

    My question is:

    Folk understand some ways to expand the virtual hard drive ranging from 100 GB to 150 GB drive hard host is only 284 GB?

    Thanks in advance.

    You explained, it is the behavior with monolithic virtual disks, which is a unique hard file. Because the file requires more space for its metadata at the beginning of the file, all the blocks of data must be copied to a new file. With the format of sparse file 2 GB virtual disks can be extended without the need to copy the data into a new file hard, because each the hard contains its own metadata. In case you don't have at least ~ 100GB of disk space you can use vmware-vdiskmanager convert/clone the virtual drive command line utility in a format of 2 GB sparse file, delete the original virtual disk (after saving), then use vmware-vdiskmanager again to rename the new virtual disk to the old name. Once done, you will be able to expand the virtual disk as required.

  • PowerEdge R510 recognizes only the 32 GB of RAM (of 64Gb total)

    Hello

    I have a server poweredge R510 1 processor (Intel (r) Xeon E5630 2.53 GHz CPU)

    He used to have 12Gb (3x4Gb) of ram, but I decided to do an upgrade.

    I bought these modules:

    8 x 8 GB PC3L - 10600R DDR3 1333 ECC Reg, is a total of 64 GB

    Unfortunately, the system recognizes that the 32 GB.

    I also tried to use only 4 modules on slots next to the empty space of the cpu, but the system didn't start because he couldn't see any ram installed.

    Can you please help?

    Thank you in advance.

    Completely, absolutely, positively and definitely sure. Dell support was wrong and they should have known better.

    The memory controller is on the processor, not on the system map, so without a processor memory locations cannot be used. The only way to get 64 GB of RAM with a single processor is 4x16GB. There is a lot of documentation.

    Running ESXi, I don't know why you wouldn't have two processors anyway...

  • Photos of virtual machines with multiple disks on different LUNS - Question

    I have some questions on how to manage the snapshots of virtual machines with multiple disks on different LUNS.  First of all, the LUNS are VMFS.  We are just starting to add virtual machines with dedicated for data storage format VMFS LUNS.  I don't think an extra space must be made for snapshots, as well as at least 100 GB LUN is required to store the data, and then say, add about 25 to 50% of this amount?  Set the 100 GB vmdk file but have the GB from 25 to 50 additional disk space for snapshots, if necessary (rather than just to get a unit number logic needed 100 GB of data and devote all of the 100 GB to the vmdk file).  In addition, if a virtual machine has several files vmdk on different LUNS, which will be a problem to take a snapshot, and is it possible to do just a snapshot of a disk of a virtual computer (as the volume of the BONE)?

    Thanks for any help.

    Snapshot files are created in the home folder of the VM by default for all virtual disks, no matter on what data store they are. You must make sure you have enough free disk space on the data store for snapshots.

    If you want to exclude a virtual disks of taking snapshots, you can set it to 'Independent' - 'Persistent' machine virtual settings to the HARD drive.
