• Problem with XServe and XServe RAID via Fibre Channel

  Hello everyone,

  I have a problem with my blended Xserve RAID.

  I see in RAID-Admin and configure it successfully (via Ethernet). Connect with our Xserve via Fibre Channel, but the XServe and XServe RAID do not detect each other.

  The fiber on the Xserve channel LEDs are white on the Xserve RAID completely off and permanent.

  RAID-Admin status of Fibre Channel: 'No connection (1 table)' with a red square.

  If I try to open the utility of fiber channel I get the message: "card Fibre Channel is not found." Utility disk OS X can't, too.

  I changed the card connector cable, and made several reboots. But each time the same thing: they do not detect each other.

  Xserve (2009):

  -2.26 GHz Quad-Core Intel Xeon 5500

  -Map of Apple dual-channel 4 Gb Fibre Channel (LSI7204EP)

  XServe RAID:

  -RAID 5 in an array (only on the left with 5 x 500 GB)

  -1.5.1 Firmware

  -Cable Apple 4 Gb SFP - SFP

  Thanks for your help and sorry for my bad English!

  Hi Mpm-Mainz,

  Check if you have enabled LUN masking. To be able to see, you will need to download raid admin 1.5 not the 1.5.1

  Xserve RAID Admin Tools 1.5

  Have you also tried to use the other controller? Even if there is no disc in there, then it should appear in the preferences of fiber card system.

  Thank you

• Configurator error 'the hard size in the first string of RAID must be smaller than the drive selected in the second Raid channel'

  Hello, I hope this is the forum for this question rigth.

  I am trying to set up a new T330 for one of our customers, and I want to use a Raid 1 + Raid 1 configuration. First raid for the operating system and daily backups, second raid for a database.

  I tried the C15c configuration, but I always get the error "the size of the hard drive in the first RAID channel must be smaller than the selected hard drive in the second Raid channel".

  Is it really necessary to buy an SSD that is bigger than the HD used in the first Raid? The DSS may be relatively low, but I need more space for the backup.

  Is there an alternative solution to this?

  Thanks in advance,

  Stefan

  Yes. In fact, you can mix drive types on the SAME channel... they just cannot be mixed in the same virtual disk (table).

• Channel 10 3 RAID?

  On the VCM install guide 5.4 and 5.5 of the hardware requirements that it lists recommended raid 1 + 0 or 10, but also to each database is assigned to a different channel on 2000 + machines?  What are the channels are referring too?

  Its kinda of a reference dated SCSI.  Nobody is talking really about channels, especially not with modern paintings according to fiberchanne/iSCSI/etc.

  Replace the word "channel" with "LUN" and you should be good enough to go.  If you REALLY want to get complicated and optimize performance, make sure that defines each of the LUNS in each channel groups they mention are accessed through a different set of ports front end on the table.

• application of RAID a6750t

  Hello

  I get a new a6750t.  I know that there are 6 SATA channels and 2 bays for HARD drives and 2 bays of DVD.  I think the configuration of the system, w / additional spare parts, can you please share your insight on whether it is possible to do?  If this is the case, what are the steps to do it?

  The original system has:

  1 1 DVD in 5.25 Bay

  2 1 3.5 HDD bay

  3. 1 media portable drive in the 5.25 Bay

  4. 1 drive Bay HARD 3.5 empty

  5. 1 empty 5.25 bay

  Planned system:

  1 get support 5.25 to 3.5

  2. Mount the original boot HDD to the bays of DVD blanks, w / support above and use it as disk HARD boot/primary

  3. as I have 2 drive bays HARD 3.5 empty after that last, that move, I can put in 2 identical HDD and use this pair in RAID 1 for data

  4. now, I

  5 1 DVD in the 5.25 Bay, 1 HDD (boot) to 5.25 bay, 1 portable media to 5.25 Bay drive

  6. 2 HARD 2 3.5 drive bays

  The questions are:

  Is this possible?

  What to look out for in terms if you use a single boot HARD disk but 1 data disk HARD RAID 1 pair?

  What measures would you propose to pass me to set this up?

  Your ideas and suggestions are appreciated.

  Thank you.

  Well, I have finally all the parts I needed for this re-config for RAID.  Here's what I did.

  Hardware side:

  1 open the PC and out of the hard drive cage, the cage holds 2 hard drives.  Remove the original hard drive w / operating system installed.

  2 use a couple of 3.5 "Bay 5.25" in square brackets, was obtained from amazon.com for $7 and mounted the hard drive of origin on these media.

  3. fit this all in spare 5.25 "Bay.  Instead of using the mechanism provided in the PC, I used a couple of screws, safer for the hard drive.

  4. put 2 new drives in the HDD cage and replace the cage in.

  5. do all the connectors for SATA and power.

  Software side:

  1. Press F10 on boot up and make sure the SATA RAID controller has the value.

  2. press on ctrl + i and go into the settings of Intel Matrix Storage Manager ROM

  3. create RAID on 2 new hard drives and choose the good.  It will help if you know before hand those who are new before closing the box on the hardware side.

  4 reboot.

  Now, I have what I decided to do, using fully all the drive bays and maximize space from my hard drive.

  Thanks for reading.

• Qosmio G30 - 148 recovery: Raid configuration / mirroring error

• Xserve RAID - easy to use stand-alone unit

  Is it possible to use a unit of Xserve RAID just by himself plugged into a mac (e.g. Mac Pro) via ethernet or require a Xserve in fact as an interface between the table and the Mac?

  Thank you.

  It will not work as long as a unit of storage/registration to access the data via a ethernet cable. You use the cable for using RAID admin administration. An XServe RAID to work its intended such as data storage and first-time buyers, will require a compatible Fibre Channel host bus adapter (HBA) or Fibre Channel switch. You don't need a server hardware dedicated as an XServe or any other thing that would be considered a server such as a Windows Server. Any Mac or PC with an installed compatible Fibre Channel card will do.

  The XServe RAID unit is a class of units RAID, called also directly Attached Storage or DAS. It is not a network (NAS) RAID storage unit.

• W530 - should I RAID or not? + Disabling Optimus

  Long story short: recently placed an order for a W530. Just checked my order shipment status and I see

  "NO_RAIDof Internal RAID - not activated."

  Also had a look at the manual W530 and I don't see what follows, because I intend to install a 2nd HARD drive:

  Hard drive bay adapter
  Model non-RAID W530 T530, T530i,
  Model W530 RAID

  Wait, what? There is no option to choose when ordering from the laptop. So in fact have a W530 RAID model or not?
  Tried to call sales, sales directed me to tech, the tech directed me to sales that I didn't have the phone physically in my hands, but back another two times before that I dropped.

  Just saw this little presentation text also in the manual on the Optimus and Intel HD4000 in the laptop. Really? This has not been at all listed in the data sheet. I plan to do a new install of win 7 so I hope that this disables optimus and keeps the computer laptop running off the quadro anytime, but everyone here would be nice enough to develop their experience, if any, with deactivation Optimus?

  Thank you! Any help I could get hbere would be greatly appreciated, after the frustration both with the channels of support tech official.

  There are 8 weeks on the W530 with RAID + Ultrabay hdd.

• HP Elite Book 840 g1: change the RAID on AHCI on Elitebook 840 g 1

  I have an Elite book 840 g1. I'm changing to AHCI RAID and cannot get it done. I tried everything on the web regarding the registry settings and changes to the bios. Nothing has worked. Any suggestions?

  Solution to change RAID AHCI on an HP EliteBook 840g 1

  My EliteBook 840 g 1 does not have a CD/DVD drive, so I put my software available on a USB stick and this worked great.

  1. back up your PC or important documents.

  2 put the software available on CD/DVD or USB depending on one you plan to use.

  3. close all programs and restart your PC.

  -C' is where it gets difficult.

  4. enter in the Bios by pressing the ESC key

  5. make sure you change your boot order / put USB or CD/DVD first in order - depending on what you are going to use

  6. once in the BIOS go to the 'Advanced tab' and then 'Device Configurations '.

  7. go to RAID/AHCI and switch to AHCI

  8 save the settings and exit.

  -C' is where it gets trickier.

  9. THIS CRITICISM IS - after save and exit the BIOS of the PC will start start - don't let it throw - back in the BIOS before it starts

  10. once in the BIOS, go to the boot options and select the option that you put your software available.

  11. now booting from USB or CD/DVD, you have your software available on

  12. your PC will now go through the re-imaging process and when it's done, you'll be in AHCI.

  13. you can check by going to "Device Manager" > double-click on ' controllers IDE ATA/ATAPI "and below you see"Intel 8 Series Chipset Family SATA AHCI Controller '.

  14. He verifies that you are in AHCI

  15 take advantage of the improved performance

  The extent of the change RAID on AHCI by using registry settings I couldn't get it work. I changed the starting value of several channels (msahci, istorA, istorV, etc.) and couldn't make the change happen. From my experience, I had to reimage my PC for that change to AHCI RAID. If someone has a proven solution, changing to AHCI RAID in registry settings without having to do a reimage would be what they please report them.  Thank you and I hope that all this information is useful.

• Reference Dell MD3000i and degraded physical disk channel

  Nice day

  We have a Dell MD 3000i with an extra box storage. And today, there are two mistakes in the journal:

  1 physical disk channel set to gradient

  In this case recovery guru say "you must contact your technical support representative to correct this defect. Do NOT try to fix this problem yourself. So, how we can receive technical support recommendations and try to repair this failure?

  If you need more details, we can put any storage array profile output.

  Hello UtkinE,

  Yes, you will need to stop all iSCSI traffic so that you can update the NVSRAM.  With the timeout error you get all came from controller 1 & he had only discs 1 & 5.  The current version of NVSRAM you version 4 and the last one which is for the MD3000i is version 13.  With who have older firmware it was improvements to correct your problem in the latest versions of firmware.  I also had one of our analysts will confirm as well just to make sure that it is the best fix for your problem.

  Please let us know if you have any other questions.

• Alienware 17 R2 RAID 0

  Nice day

  A year ago there's response in a video on YouTube (youtube.com/watch? v = GCemSCC_QaQ - this official support channel video Alienware) that RAID is not available for this laptop

  For today, is it possible to create RAID 0 of 2 SSD m2?

  Thanks in advance

  Hello

  The value of R2 AW17 has not the RAID option in the BIOS. If a RAID 0 array is not possible.

• EqualLogic configuration and restrictions of RAID

  We realize that there is NO way we can remove the existing RAID array so that we can replace several drives at once only to rebuild a new RAID. Feedback from the Engineer Support of Dell that if we act with this, we will need to use a connection series for reset and reconfigure the EQL scratch all on again once. Is this true?

  Is there really no way to replace several drives in EQL without having to reset the entire system?

  We meet also restart and EQL will stop when he was not able to rebuild the RAID, taking the storage offline without giving any possibility to proceed. So we are forced to connect return old hard disks and wait for it to rebuild the RAID. And despite having zero data and zero volume, reconstruction takes always the hours to complete.

  Low-end NAS allow to remove the RAID and replace all disks while keeping the existing configuration. However, it seems that high-end EQL has no way to retain the existing configuration if need to replace multiple disks or RAID could not rebuild.

  Is there a way we can save the existing configuration, we can restore?

  Finally, it will be good if EQL could show what channel/RAID 50 each hard drive is a place where we can replace up to 4 HDDs without bringing the RAID rebuild process to a halt and cause a stop and restart again.

  A connect as that of grpadmin?

• C210 M2, questions RAID, impossible to see readers

  Hello

  We have a server C210 M2, unfortunately the LSI RAID controller was not in order.  We bought a LSI MegaRAID 9261 - 8i separately as well as 2 x 0.75 m SFF-8087 cables to connect x SAS 5 readers, that we have to the server.

  We cannot get the RAID card to recognize all readers.  They are loaded into the drive bays 1-5 and the two channels on the LSI card is connected to the ports ' discs 1-4 "and"disks 5-8"to the Board of Directors.". "  I assured the integrated controller is set to ENHANCED within the BIOS and tried the RAID card in several locations.

  The card LSI or different cables to the Cisco card brand?

  Thanks in advance

  AS

  I had situations similar to what your experience solved using the Cisco cable provided.

• Controller SCSI Raid ESXi 5.5 recommendation

  I'm moving the ESXi 5.5 to another server by using the following:

  
  

  Server Dell R610 with 12G of ram and a Dell PowerVaul 220 s Raid 5 with 12, space 1, 5 - T HD sata

  The Raid Controller is a Intel SRCU42E Ultra320 SCSI PCI-Express X 8 with ext 2 x 68pin ports.

  
  

  I get the error ' call 'HostDatastoreSystem. " 'Of object' CreateVmfsDatastore 'ha-datastoresystem' on ESXi when you try to add storage. I even installed 5.1 but with the same results.

  
  

  Later, after much research and troubleshooting, as well as headaches, I discover that the SCSI Raid card was not compatible with ESXI 5.1, 5.5 only with 4.1 or 4.0

  I begin to scan the cards SCSI RAID but difficult to get one with the above specifications that could be compatible with ESXI 5.5

  
  

  Run out of tricks and do not have the ability to turn the Dell PowerVault 220 s

  May suggest a SCSI Raid PCI - e card with a port Ext. 68pin compatible 5.1 to 5.5? All of the recommendations, difficulty, work around?

  Thank you

  ESXi 5.5 system requirements

  When you install or upgrade to ESXi 5.5, ensure that the host meets these minimum hardware configurations supported by ESXi 5.5:

  1. Your equipment is compatible on the VMware Compatibility Guide. This includes:
  • Systems compatibility
  • Compatibility I/O (network adapters and HBAS)
  • Storage compatibility
  • Backup software compatibility
• You have a 64-bit processor. VMware ESXi 5.5 only installs and runs on 64-bit x 86 CPU servers. He argues also that LAHF and SAHF CPU instructions.
• You have a computer with at least two hearts 5.5 ESXi host.
• The NX/XD bit is set for the CPU in the BIOS.
• Your processor is supported. ESXi supports a wide range of x 64 of multicore. For a complete list of taken processors supported,
• You have 4 GB of RAM. This is the minimum required to install ESXi 5.5. Provide at least 8 GB of RAM to take full advantage of the features of ESXi and run virtual machines in typical production environments.
• Support for hardware virtualization (Intel VT - x or AMD RVI) is enabled on x 64 CPU (to support 64-bit virtual machines). For a complete list of operating systems that are supported with ESXi, hosts running virtual machines with 64-bit operating systems have these hardware requirements:
  • For AMD Opteron systems, processors must be Opteron Rev E or later.
  • For Intel Xeon systems, processors must include support for Intel Virtualization Technology (VT). Many servers which may include processors with VT support VT disabled by default, so you have to manually enable VT. If your CPU support VT, but you do not see this option in the BIOS, contact your provider to request a version of BIOS that allows to enable VT support.

    Note: to determine if your server has 64-bit VMware support, download The utility of Identification of CPU on the VMware site.

• You have one or more Gigabit or 10 GB Ethernet controllers. For a list of network adapter models supported, refer to the VMware Compatibility Guide.
• You with any combination of one or more storage controllers are:
  • Basic SCSI controllers. Adaptec Ultra-160 or Ultra-320, LSI Logic Fusion-MPT and most NCR/Symbios SCSI.
  • RAID controllers. Reference Dell PERC (Adaptec RAID and LSI MegaRAID) RAID HP Smart Array or IBM ServeRAID controllers (Adaptec).
• You have a SCSI drive or a local, off-grid, RAID LUN with unpartitioned for VMS space.
• For Serial ATA (SATA), a drive connected through taken SAS controllers supported or supported integrated SATA controllers. SATA drives are supposed to be remote, no premises. These discs are not used as a partition to scrape by default because they are too far away.

  Note: you cannot connect a SATA CD-ROM device to a virtual machine on a host ESXi 5.5. To use the SATA CD-ROM device, you must use the IDE emulation mode.

• You use a supported storage system. ESXi 5.5 supports the installation and start-up of these storage systems:
  • SATA drives. SATA drives connected behind the SAS controllers supported or SATA controllers support built-in.
    • LSI1068E (LSISAS3442E)
    • LSI1068 (SAS 5)
    • IBM ServeRAID 8K SAS controller
    • Smart Array P400/256 controller
    • 5.0.1 Dell PERC controller
  • SATA drives. Support SATA edge include:
    • Intel ICH9
    • NVIDIA MCP55
    • ServerWorks HT1000

  Note: ESXi does not support using SATA internal disks local to the host server to create VMFS stores of data that is shared between multiple ESXi hosts.

• You have disks Serial Attached SCSI (SAS) supported for ESXi 5.5 installation and to store virtual machines in VMFS partitions.
• You have dedicated disk SAN Fibre Channel or iSCSI.
• You have USB devices supported for ESXi installation.
• You can install and start ESXi a FCoE LUN using VMware software FCoE adapters and network with FCoE adapters discharge capacity
. See the documentation for storage for more information about installing and initializing ESXi with vSphere FCoE software.

• For ESXi 4.1 - 2805 Adaptec RAID controller?

  Hello.

  ASUS is not come through one of the PIKES are delivering controllers, I am looking for an another SAS/SATA Raid Controller supporting at least 6 disks and Raid 1 + 0, what I also learned as ESXi requires that it be a H/W Raid Controller.

  I'm looking on the Adaptec RAID 2805 controller specifically.

  It is one of the adapter entry level Raid controllers, then it is offered at a low cost and whereas it will be a small "House" use server runs a number of images of Windows/Linux, I don't think it would be as sensitive as the price difference is to choose an Adaptec RAID 5805 controller instead.

  It is, does anyone have any experience with the Adaptec RAID 2805 controller? Since it is not listed on the compatibility guide, however the Adaptec RAID 2405 is and as far as I can tell the difference is the number of channels op. the 2405 would properly cover my needs as well if I could find a retailer for her near me.

  So, the question, because any who have experience running VMware ESXi 4.1 on a Raid 1 + 0, using SATA disks with any of the listed controllers?

  OK, found a Danish dealer who could acquire the LSI card.
