• Satellite l.660-12 q - would the recovery disk rebuild the new HARD disk with a new recovery partition

  Talk about confusion. Does anyone know how to get a Toshiba C660 work after the HARD drive failed and the owner has stupidly NOT followed the instructions to make a recovery disk. Will be the recovery disk (if buy you one from Toshiba) rebuild the new HARD disk with a new recovery partition and install windows 7 (original OS) and accept the product key printed on the Windows license, attached to the base of the laptop. I have read a number of suggestions, but these have been considered incorrect by others.

  Surely, Toshiba must have a way to sort this problem.

  They read these messages?

  Hey Buddy

  I don't think it's really complicated, that I could find all the information about the recovery procedure in the user's manual

  The recovery disk must be created on the first day of purchase its recommended to create one in case something would be wrong with the HARD drive.

  The recovery disk contains an image. The image is a package containing Win system, drivers, tools and all the stuff pre-installed on the notebook.
  You bought the laptop and the system has already been activated so that you have need of t the key placed at the bottom of the unit.
  In addition, the use of the recovery disc formats the drive HARD integer (partitions too) and set the laptop in the same condition as at the first day of the purchase.

  There is also another option to recover the notebook called HARD drive recovery. This HARD drive recovery requires no recovery disk. The recovery disc HARD would be to use format ONLY partition C (System).

• the 'My Computer' folder will not show the disks in groups

  the my computer folder of work does not show readers in groups like he used to.

  for example, there is usually something like the files stored on this computer and the case of all documents then hard drives and it shows all disks ect.

  but now it shows just the icons, and I can't show the readers in the groups more. How can I show him again into groups

• Unlike RAID disk drives groups / virtual

  Hello

  What is the difference or the benefit of making the RAID groups or virtual disks for a RAID configuration? For example, what is the difference with the situation below:

  PERC controller:

  0, RAID 1 disk group

  -ID: 0, 1 virtual disk with 2 physical disks
  

  1, RAID 1 disk group

  - ID: 1, ramdisk with 2 physical disks

  OR

  PERC controller:

  0, RAID 1 disk group

  -ID: 0, 1 ramdisk with 2 physical disks

  -ID: 1, 1 ramdisk with 2 physical disks

  If it's 1 diskgroup with multiple virtual disks, each of these virtual disks will be distributed across all disks in the diskgroup.

  So I guess that you meant:

  Disk group 0, 1-2 physical disks Raid

  -1 single virtual disk size max

  Group 1 on disc, the 1-2 physical disks Raid

  -1 single virtual disk size max

  OR

  Group 0 of disk, Raid 10-4 physical disks

  -2 virtual disks of the same or different size

• two flash disks in a single disk group vsan

  Every morning.

  We had our second ssd flash not to shoot the entire disk group in vsan, not a problem all the resynced and recovered ok.

  I know that we can make groups of multiple discs for each host with its own flash ssd by group, my question, do we put two SSD flash in a single disk group? If so, if one of the two breaks down the entire disk group go offline? or will she continue to work ok until these two flash drives don't?

  Thanks in advance

  Band 2 will improve performance, the FTT2 will lower write back-end IOPS / s (perhaps a problem, perhaps not according to the back pressure and filling of the cache). In theory, it could improve read performance cache miss, but between the CRA, the system cache read-ahead for a absences from the cache and all the rest I do not expect much.

  Small groups of disks, etc. more flash. I would recommend you start observer VSAN and watch your hit rate Read Cache and see if another groups of disks (and Flash) would be a good idea.  You tend to get diminishing returns, trying to push beyond the 90% cache hit rate

  To keep in mind that, unless you have a balancing really bad object (it would take much effort to be honest attention creating VM and deletion and then affecting the PAF policies to create) you should see a heavy a lot to rebuild many (IE when a disk or group of disks is lost the pairs of mirror for these objects will be scattered across the cluster and they will rebuild in) free space of all other disks until mirroring policy is armed).  Keep in mind that the objects is already memorized block in new components never 256 GB (by default). Because of this design as the cluster becomes larger and more areas of failure (host, disk groups, readers) ads you expect actually rebuild performance better!

  Have you experienced problems of performance on your reconstruction, and if so what are your flash/disc types and make the model of your server HBA etc.?

• Oracle 10g RAC + ASM + Data Guard: Question on the new disk group.

  Hello
  
  One of our clients is to have Oracle 10 g RAC + ASM + Data Guard. Database is the disk DATA_DG1 group and FRA is on FLASH_DG1. Data Guard is a single instance on ASM.
  
  To add more space, we can create another disc of the Group DATA_DG2 on Prod ASM and Data Guard ASM env, replication continues without any problem. Will be archiving logs shipped to the second disk DATA_DG2 group and applied without any configuration changes?
  
  Rgds,

  Yes, it sounds great.

  You should be fine with the implementation of these measures and the dataguard should continue on as usual.

  Just make sure that you are dealing with a physical standby that has not the conerts file name defined.

• How to assign several groups of home page tabs?

  I was hoping to make use of the tab function, but when I restart FF my groups all disappear except my home page tabs. Is there maybe an add-on that can save and rebuild groups of tabs?

  And is it just me or should FF have warned me that the creation of a group of tabs set my home page and remove my links?

  Also, I wouldn't need to tab groups if the new tab screen can be configured to contain more links with small vignettes - perhaps also a possibility to Add on?

  Thank you...

  Finally got a chance to try it - looks great so far. Configurable Super - lose the search bar, reduce the size of the tile while maximizing the police to name, create custom groups...

  There will be no problem to get everything I need on a single screen with scrolling - just wish I could reorganize and group in a single screen.

  I see no reason to set as my homepage though - there are several tabs, I always open so 'new tab' mode, that's exactly what I was looking for.

  Thanks for the help,
  CC

• swap disk failing on R510

  Sorry for the basic question, but I'm happy to be considered a fool if I can

  do things.  :)

  Error on LED is "E1810 HD 5 fault"

  This disk is part of a RAID-1.  Machine is running CentOS 5.  OMSA is not installed.

  R510, 8 car chassis.

  What is the recommended route to replace the defective drive?

  (1) hot swap by pressing the button delete drive, install the new drive, cross your fingers, automatic

  rebuild?

  2) starts at Dell Support Live, run OMSA who go and do the replacement of this way

  3) go into the BIOS and make the replacement here.

  (1) is easiest if it works, of course, but it's an important machine, so the safest way

  is the best.

  Thank you very much for your time.

  See you soon

  None of them are "safe".

  1) there are many reasons that may prevent disk rebuild automatically, if it does not rebuild automatically, without OMSA, so you'll need one of the other methods to clear foreign config or assigned as a hot spare to start reconstruction.

  Just make sure that you insert the ' hot' drive (not being able to replace).

• San virtual magnetic disk fault tolerance

  If I have several magnetic disks in the disk group a single host. Is VSAN will detect this failure and if so, how?

  Part 30 & #8211 VSAN. Difference between absence & amp; Degradation of components | CormacHogan.com

  See Cormac's great post on absence degraded components vs.  If a disk is detected as absent, vSAN will wait for 60 minutes (default value, this can be changed) to clean up.  If a drive is detected as degraded, reclamation will be immediate.

  He is magnetic only, a disability SSD will make the entire disk offline group.  Thank you, Zach.

• How to find the file on the disk of the ASM

  Hi all
  I'm looking for what dbf files are stored on a specific DRIVE of a DISKGROUP in an ASM instance.
  E.g. Diskgroup-> Group-> 1 + DATA

  I want to know what everything is stored on DATA_002?
  Can we get this info?

  You can't see the files at the level of the ASMDISK, this info is only available at the level of the DISKGROUP.

  Oracle ASM spreads data evenly across all disks in a disk group to optimize the performance and usage. So, the DATA_002 ASMDISK has a piece (extensions) of all files stored on the DISKGROUP.

  For example, if there are six disks in a disk group, and then pieces of each Oracle ASM file are written in all six disks. These pieces are called extensions. In this scenario, these pieces are in blocks of 1 MB. When a database file is created, it is striped (divided into degrees and distributed) through the six diskettes and allocated disk space on six discs increases uniformly.

• You can use local drive as the mapped drives raw groups

  We have a new host with vShere4U1 installed on a couple of mirrored disks.  The host will initially run a SQL server and the operating system will be SAN (fibre) as all of our other machines are virtual host.  We do not have enough space on the SAN or the budget to upgrade to allow us to run the newspapers/Db SQL, then the host was purchased with an extra 14 discs (much less expensive) who were divided into two disk RAID groups 1 + 0 (410Gb & Go 540)

  I can attach disks locak to the host, but it is shaped as a vmfs and the dbo wants to use these discs as raw as he wants to use the size of the set and is limited to 256GB VMDK in the vmfs.

  Is there a way to present records in vSphere while they give me the opportunity to fix to the virtual machine as raw disks similar to the san, or in any other way.

  I'm a pretty confident user of ESX without being an expert (admin typical average closed sys - too many hats) and basic linux would be appreciate some comments/help.

  Home - HP DL160 G6

  See you soon

  If you remove the data store and then choose a block size, you can have a data store up to 2 TB in a single LUN. If you need you can extend the data to 62 to using extensions store.

  You really want to use raw disks. I don't know if it is possible anyway.

• ASM disk management

  Hello
  
  In the concept of the ASM, we have a separate user to manage the asm instance. It belongs to the osasm, osdba, osoper groups.
  My doubts, it is who will manage disks and groups of disks. is it by user sys or asm special.
  
  Thank you!

  You are confused in the ownership of the devices and the Management of the ASM IMO. Ownership of the ASM devices would be with the user which of 11g, must be a different user on the o/s than oracle , for example the grid . This would have the property on devices and the asmadmin group would be to have the Group property. The device management in the form of disk groups and the ASM instance in general will be with the Sys account using the role of Sysasm of 11.2.

• VS SAN storage. The internal server disks

  What are the Pro and Con is to use a network SAN or disks on internal server as storage for database files.

  user771256 wrote:
  If we have a RAID disk array and then she would be able to configure the following separate volumes 1-3 and 4-6 discs and it will not be controlled by a San.

  Physical disk 1 |
  Physical disk 2 +---> lvol 1 - mounted on /ora01
  Physical disk 3 |

  Physical disk 4 |
  Physical disk 5 +---> lvol 2 - mounted on /ora02

  Thank you-

  Once more, multiplexing of the files is a matter of oracle , and has Nothing to do with the fact that you are on a San, a local RAID or the local disks of discreet. If the directories where you put files are on separate disks, files multiplexes will be on separate disks. If the directories are not on separate disks, files will not be on separate disks. Oracle does not know or care if they are on disks separate or not, as that are totally abstract by the storage system.

  I thought that the foregoing was clear enough... So let's continue, assuming that the above has been put in place...
  Assumes that the value for ORACLE_SID = orcl

  oracle> mkdir -p /ora01/oraredo/$ORACLE_SID
  oracle> mkdir -p /ora02/oraredo/$ORACLE_SID
  

  Then in sqlplus:

  ALTER DATABASE ADD LOGFILE GROUP 4 ('/ora01/oraredo/orcl/redo4a.rdo',
                                      '/ora02/oraredo/orcl/red04b.rdo')
  SIZE 51200K
  /
  

  red04a. RDO will be placed on the /ora01, which is mounted to lvol1, which uses disks 1-3.
  red04b. RDO will be placed on the /ora02, which is mounted to lvol2, which uses disks 4-6.

  In fact, at least on my SAN, it has another layer of abstraction: physical disks are grouped (in which raid configuration chosen) in a "disk group. Several groups of disks can then be grouped into a logical volume (lvol).

  disk 1    |
  disk 2    +--- Dgroup 1  +
  disk 3    |              |
                           +---  Lvol 1 ---> mount to /ora1
  disk 4    |              |
  disk 5    +--- Dgroup 2  +
  disk 6    |
  
  disk 7    |
  disk 8    +--- Dgroup 3  +
  disk 9    |              |
                           +---  Lvol 2 ---> mount to /ora2
  disk 10   |              |
  disk 11   +--- Dgroup 4  +
  disk 12   |
  

  In this new scheme, all files written in any directory under /ora1 can be written to any drive in dgroup 1 or 2 - disc 1-6. If a striping RAID config is used, the file will be broken into pieces and written to all the drives from 1 to 6.

  but I wanted insurance with people with experience as you go this drive on differnet LUN will not impede performance.

  A LUN is a logical unit - it may be a single physical disk. It may consists of 20 physical drives. If the LUN itself does not determine the performance. Performance is determined by the parts in movement under it.

  Multiple LUNS to the same diskgroup using or the volume of file system is a common practice. If this would be a problem (performance or otherwise) depends on the cloth under the LUN.

  For example, a logic unit number could be RAID5 and another logic unit number can be RAID0 + 1. Mixture of different RAID levels is not really a good idea.

  A LUN can be a storage on a San and accessible via the fiber channel. Another logic unit number could be an iScsi device, accessed through intellectual property. Mix very different storage architecture and storage protocols are not a good idea.

  A LUN can be RAID0, through fiber double channels connected to a switch, for the storage of 1 storage server. Another logic unit number can also be RAID0 and accessible through the same fiber channels and switch, but since the storage server 2. Whereby the RAID levels are the same and the storage Protocol and infrastructure the same - and that will not only make a compatible mix, but can actually increases the redundancy if you use these as disk mirrors ASM (which means that ASM can lose the server storage 1 or 2 and still works).

• Cannot remove HARD disk configuration PERC 6i with use of the SAS drives foreign. Existing data are not important. Scratch reloading to redeploy the server.

  Dell Poweredge 2950 III with serial number note from the Admin: have the label removed according to the TOU > receipt readers traded since an identical poweredge almost eliminated. In the configuration of the PERC controller 0 6i utility, disk groups show as foreigners. Messages following the procedure to import the configuration, then remove before was not effective. The prior configuration appears in the menu.

  I would like to simply clean configurations of VD for the readers and the controller. After it is deleted then next step is to set up a configuration I want. My new Setup is not relevant for this post. The goal and the only question is how to clear existing shared disk configurations.

  VD0 clear addition to figure 2 SAS PD/hard drives as virtual disk unique. RAID levels 0, status is offline, SMART status not = no error, County VD = 1, PD = 2 count, operation = none

  Is a similar to VD0 VD1

  other berries are currently empty.

  For initial troubleshooting I have removed all the HARD drive except a single disk on the server. This disc shows also as stranger.

  In the PERC 6i config utility:

  VD MGMT doesn't show CONTROLLER0 - no configuration is present. Choice of the F2 are Config. Foreign config based on availability. (Create new VD and manage preserved Cache are greyed out) Right pane of the screen indicates "foreign Config present, controller prop.: DG = 0, County VD count = 0, County of PD = 1".

  PD MGMT shows only the formatted Mo 139 K SAS single, foreign = State, SMART status not is no mistake, operation = none

  VIEW FOREIGNERS shows DG0 = foreign, Virtual disk 255 with DG count = 1. County of VD = 1, County of PD = 1

  I installed 3 of the disks individually rotating as a single HARD drive with similar results.

  WITH 2 HDD SAS installed only difference is VD Mgmt shows County DG = 0, County VD = 0, County of PD = 2.   View foreign shows VD255 prop: Raid 0, Raid = foreign status, size = na, operation = none. | Disk prop group. : VD Count = 1, County of PD = 2, Ded HS = 0 (because it does not exist).

  Thanks Chris. Problem is solved. I would like to Flash the firmware as precautionary measure? Still confused why initial in the VD Mgmt tab procedure has failed.
