• I would like to migrate from Aperture. What happens to my masters that are on a RAID array and then what should I do with my safe which is located on a separate drive please?

  I'm sorry, but I'm loud understand what happening to my master original RAW files, I keep offline on a RAID array and then what I do with my safe that, like all my photos modified? Sorry for this simple question, but would someone help please my lift the fog?

  Thank you

  One of the major downfalls of Aperture is that it shows you where are your pictures. They always favored it as a feature (even as a ' new paradigm'), but it's not so wonderful when you need to do something about Apple never intended. Then, it sounds really like it led to you not knowing where your files or files that correspond to which elements of the UI opening. I suggest that you need to nail for yourself - images from Aperture to right click and choose Show in Finder, until you know where everything is.

  Otherwise, make sure you have plenty of available disk space, stop asking questions and just see what happens when you run plugin import LR with the options I suggested. It won't damage the opening.

• Best Configuration for optimal IO RAID parameters and ESX 3.5 vmfs volumes

  Hello

  We currently have ESX 3.5 update 3 installed on a HP DL585 and connected to a HP MSA 1500.  ESX is installed on the server in a RAID 1 2 x 72 GB configuration.  I tried to determine the best possible configuration for the VMFS partition on the MSA 1500 (or more), but it seems to be getting some mixed reviews between RAID 1, RAID 5, and RAID 10.  That's why I thought I post the question and I hope that some people have recommendations.  Even if the disk size and type may be the best available and we can add to write the memory cache to the MSA then let me know the following... I'm coming looking with better i/o performance overall as well as redundancy (number of readers and size is not limits so if we had better available so how would he).  Assuming that VM will perform a high volume of reads/writes:

  1 size Max of LUN to optimize i/o performance (I have read 250 GB but perhaps it can be more)?

  2 for the LUN RAID configuration (RAID 5 or RAID 10, as well as all others who may still be better)?

  3. number of disks to span as appropriate?

  4. the amount of memory to install in the table itself or if anything be installed within the guest card and/or fiber ESX?

  Thanks in advance

  I'd say go with RAID 10

  Number of disks and the size depends on the VMs that spins the discs,

• 9.2.0.6 moving database files and redologs using the dd command.

  Hi all,
  
  I need to know if someone have take a cold copy of database (data file and redologs) using the unix dd command.
  The problem is related to the value to be assigned to "bs" in the DD.
  
  For the data file, I know to do the same thing of block_size for the tablespace. I'm not sure of the value to assign to "bs" to the redologs.
  
  Any suggestions are appreciated.
  Thanks in advance

  PS. I'm pass raw partitions of the data files and of redologs from HP - UX 11.11 RISC on SYMM8830 for HP-IA64 using lvm on HP XP24000 with veritas.

  as to the "bs" to command "dd"?

  DD if = of = bs = 1000M

  If your raw device is in GBs, you can give a higher as 1024M... Sometimes the operating system does not have higher values as 1 GB... in this case, you can give all the values as 1024 K, 100 M, 500 M... Like this...

• z820: looking for a software raid manage and view the status of disks hard raid

  HP z820 workstation,

  product # D3J63UT

  I'm looking for raid management software

  

  Thank you.

  I suggest that you follow the steps listed in the HP Document: "Z - series Workstation detection and fixing a hard drive failure within the RAID Controller utility" in the URL: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c04474148#N10829 you can find instructions how to enter each State type of RAID (Intel RST, 2308 LSI and LSI 9260-8i controller - It's the main RAID controllers usually associated with the HP Z820 workstation according to the particular configuration you ordered). Note that in most of the cases described in this document, you need to access the configuration of RAID controller during computer startup steps, by pressing CTRL + I (for Intel RST) or CTRL + C (for LSI 2308) or CTRL + H (by LSI 9260-8i). The installation program uses the RAID controller firmware and does not require to install complex inside Windows software, because it is done outside of the Windows operating system before starting. Find more details in "HP Z220 SFF, CMT Z220, Z420, Z620 and Z820 workstations maintenance and Service Guide" in the URL: http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c04205252-1.pdf , in the devices of annex b: Setup RAID (pp. 161-171) all types of RAID controllers that are relevant at the workplace Z820 are discussed.

• LSI Logic SCSI Ultra320 RAID Firmware and the BIOS utility. Cannot make the diskettes.

  I downloaded the pack sp29637 for Firmware LSI Logic Ultra320 SCSI RAID and the BIOS utility to my Workstation xw 8200. I'm doing a disk from the downloaded file. I runs the file, but when it tells me to put a floppy disk in the A: drive and I confirm, the window closes and the diskette is not made. Looks like the copy in the file program is corrupted.
  Does anyone have this already developed package files so I can copy them to a floppy disk?
  The files are supposed to be the following:

  Yes you are right. Then, I realized that I could open these files using Winzip or Winrar. I thank very you much for responding to my post.

• Reuse a RAID disk and hot spare procedure

  My questions are for a PE R720xd with the PERC RAID internal H710P controller.

  I have replaced several RAID drives in the past, but I never did this before, so I was hoping to confirm my procedure for hard drives hot swap. A drive failed on one of my live servers. In the past I would always bring back the server during a maintenance window and replace the drive by using the configuration utility to make sure everything went correctly. This particular server has become a system of very high availability, so I was hoping to use for hot spare option do without bring down the server.

  The other issue is that Dell is not in stock on the disk, I need so I intend to use a same car I replaced recently on a server off-production that has already been fixed in a RAID1 in another Dell R720 Server table. Any time, I have never replaced a RAID drive, I always used a new drive out-of-the-box, so I'm also not 100% on how to prepare the drive to use for a new RAID array.

  I thought I am brings the donor server down and come off the drive I want to enjoy this the RAID array server using the configuration utility. So a question is - is there anything else I need to do preparation used in car for use in the new table?

  With respect to hot-swapping which lead to the new array, is it really as simple as just popping one out and put a new in? Can I do to confirm it has taken - apart from just confirming that the lights blink like crazy during synchronization?

  Thanks for your understanding!

  C.Short,

  You can switch the drive, but it will be not just to rebuild there is data on the hard drive. So when this disc is inserted, it will show foreign. You will need to do is to boot to the controller (Ctrl + R) and then CLEAR the foreign Configuration. Once completed, then you will be able to rebuild the disk on the virtual disk, you can do the BIOS of the controller, or from the OpenManage web interface (depending on the operating system).

  Let me know if it helps.

• General on the raid controller and hardware

  Hello

  I have that the hard disk controller or controller raid (0,1,5) does not work on a computer, if I add hollow PCI slot a wil raid controller or hardware, computer, or the raid not works normally?

  Johan

  Hi Johan,.

  Thanks for posting on Microsoft Community Forums.

  Ideally it is dependent on the PCI slot you use, if the PCI slot supports the hard disk controllers and RAID controllers so it will work with the computer. Almost all modern PCI slots supports the hard disk controllers and RAID controllers.

• Instance recovery fast and redolog file size

  Hello
  
  Could you please explain to me how redolog file size allows to retrieve the instance more quickly?
  
  Thank you
  KSG

  Soon, I'll try to say.

  The answer lies in the relationship between the number of buffers Sales necessary for recovery. Buffers dirty necessary for recovery is limited by the checkpoint process when DBWR is ping some of them writing in the data file. So with a log switch, you'll hit a control point. So if the size of the log files to be smaller, frequency control would be great, which makes written buffers more aggressively in the fikles of data and limit the duration of the reocvery instance. Her biger make you, it would take more than the checkpoint occurs and so in the case of instance recovery, it would bemore time required. That said, using a log file of small size would also lead to "cehckpoint inicomplete" error as well, because it can happen that DBWR will not be able to match with his own writing speed and the speed of the current generation gate of event.

• MD3200 (SAS) Raid controllers and VLAN

  I have a MD3200 (SAS) and the host running ESXi 5 U2. Is it possible to configure the VLAN tagging on the management ports of the MD3200 outside the standard IP gateway configuration and the subnet mask?

  I don't see one either. Textbooks mention also the option to label the management ports.

  Based on the absence of mention of this in the manual, I feel confident in saying that you can not use VLAN tagged on the management ports.

• Create RAID 1 AND RAID 5 berries T330 PowerEdge

  Hello

  Is there a way to create a RAID5 located with a pre-existing RAID1 of the OMSA? I don't see anything that would allow me to do. I have 2 3 to disks, do nothing, but are not available for RAID5, just 0 or 1.

  Thank you

  If one of the 2 TB drives is currently defined as a backup, you will need to cancel the award until it is available to be put in a new table.
