How to add a disk to a VM in order to be seen as a raw device?

I am running Hyper-V in Windows 8.1 Pro with Oracle Linux installed in the VM. I am running in the Linux VM an Oracle database (for testing purposes). I want to add a SSD which is seen as a raw device by the VM. Is this possible? How?
As far as I understand in order to assign devices to a VM you need Vt-d, which must be supported by the CPU (i7-4771), motherboard (Intel DQ87PG) and by the hypervisor. Is this
correct? The CPU and the mobo both are supporting Vt-d last time I checked.
Thanks,
Codrut

you can add pass through disk to the virtual machine

How to add more disk space into /   root file system

I would actually question whether or not more disks increase the risk of a disk failure. One disk can break as likely as one of two of more disks.
Simple stats. Buying 2 lottery tickets instead of one, gives you 2 chances to win the lottery prize. Not 1. Even though the odds of winning per ticket remains unchanged.
2 disks buy you 2 tickets in The-Drive-Failure lottery.
Back in the 90's, BT (British Telecom) had a 80+ node OPS cluster build with Pyramid MPP hardware. They had a dedicated store of scsi disks for replacing failed disks - as there were disk failure fairly often due to the number of disks. (a Pryamid MPP chassis looked like a Xmas tree with all the scsi drive LEDs, and BT had several)
In my experience - one should rather expect a drive failure sooner, than later. And have some kind of contingency plan in place to recover from the failure.
The use of symbolic links instead of striping the filesystem protects from the complete loss of the enchilada if a volume member fails, but it does not reduce the risk of loosing data.
I would rather buy a single ticket for the drive failure lottery for a root drive, than 2 tickets in this case. And using symbolic links to "offload" non-critical files to the 2nd drive means that its lottery ticket prize is not a non-bootable server due to a toasted root drive.

How to add additional disks on vmware OEL4 and use it for Oracle 10gR2?

I created a virtual machine on vmware workstation 6 and installed OEL4.
during first install I created 20 GB disk but now I want to add more disks.
from vmware documentation I tried to add more 8 gb disk to the virtual host.
under devices I see two lines;
Hard Disk (SCSI 0:0) 20.0 GB
Hard Disk (SCSI 0:2) 8.0 GB
but I must be missing some step since I can not see 20 + 8 gb at df;
[root@antuhost ~]# df -h
Filesystem            Size Used Avail Use% Mounted on
/dev/sda1              13G 9.7G 2.3G 82% /

How to add a table layout in CRM Sales order?

dear all ,
anyone know how to add a table layout in CRM sales order customer tab that using the EEWB added?
can EEWB do this? i didn't find the appropriate business object......

Hi , Swapna
is you mail address right? can not send out.
first , you should have added one field using EEWB , then to EEWB , find the extension , double click on the task, there you will find a "object list" on the right, the list will give you many many very important information , you should look through .
then double click on the "screen: ..........EEW......." , layout , there you will find the field you have added in . and you can draw anything you want there , then back to the screen flow , write you flow logic in PBO and PAI .
about the global data definition, again to the "object list", you will find a "Report source code: ......................TOP". in there ,you can define all you data .
another thing if you want to save your input field to database tables that you draw (not by EEWB added)
two ways:
1. write update table directly in PAI module .
2. you can use this BADI : ORDER_SAVE , this is when you save the order to trigger the save action.

How to add ASM Disk to Disk Group that is shown as MEMBER?

HI,
We have a Production Oracle RAC on HP-UX. We have Two Disk Groups one for Arcive (ARC_DISK) and other for Database(DATA_DISK).
Today I wanted to add another 200 GB of Disk Space to the DATA_DISK Group.
I opened DBCA and could not find the new disk in the 'Show Candidates' option. But after the Unix admin changed the ownership and permission of the Disk, it was shown in 'Show Candidates' option. I selected this Disk and continued but got an error later as we didnt change the ownership and permission from the 2nd Unix server. After doing this, , when I open DBCA to add disk, nothing is shown in 'Show Candidates' option but when we click on 'Show All', the new disk is listed as MEMBER (header status) but not allocated to any Disk Group.
I would like to know how to allocate this Disk (which is already shown as MEMBER) to the DATA_DISK - ASM diskgroup. This is a production database system.
Rgds,
Thiru

Hi,
Due to huge difference in Disk Size which I am trying to add to the existing Disk Group which has 1024 GB of Disk, would it be a better idea to create a new Disk Group with 200g GB Disk? Will this command work as the header_status is already MEMBER?
SQL>CREATE DISKGROUP DATA_DISK1
EXTERNAL REDUNDANCY
DISK 'disk path';
Thanks.Yes, you can create new diskgroup (DATA_DISK1). Just make sure all datafile in DATA_DISK autoextend off, then create all your new datafile to the new diskgroup DATA_DISK1. The command will not work as the header_status is MEMBER. You'll receive ORA-15018 & ORA-15033 error. As I mentioned before, you need to use FORCE option or format the disk using dd* command before perform above command.
1st Option : (Format the raw disk using dd command creating new diskgroup. Header_status MEMBER -> CANDIDATE). E.g.
1. dd if=/dev/zero of=/dev/rdsk/c2t1d0 bs=8192 count=1000 //any rac nodes
2. # chown oracle:oinstall /dev/rdsk/c2t1d0 //perform on both node. This apply if using LVM or direct access to raw
3. SQL> create diskgroup data_disk1 external redundancy disk '/dev/rdsk/c2t1d0'; //any RAC node in ASM instance
4. SQL> alter diskgroup data_disk1 mount; //try to mount on the other node
2nd Option : (Using FORCE option when creating the new diskgroup. Header_Status = MEMBER)
1. # chown oracle:oinstall /dev/rdsk/c2t1d0 //perform on both node. This apply if using LVM or direct access to raw
2. SQL> create diskgroup data_disk1 external redundancy disk '/dev/rdsk/c2t1d0' force; //any RAC node in ASM instance
3. SQL> alter diskgroup data_disk1 mount; //try to mount on the other node
Just be careful when using FORCE option or DD command. If you perform this operation on existing ASM disk groups disk, it may destroy existing disk groups.

ABAP: How to add a Price Condition Item to an order item

Hi experts,
Is it possible to add a Price Condition Item to an order item by BAPI or Function in sap crm? (like: 0k04 10 USD 1 EA)

Hi,
You need to use CRM_ORDER_MAINTAIN and have to use structure IT_PRIDOC to update or add new pricing data.
But do remember, you have to call FM 'BAPI_TRANSACTION_COMMIT' once you are done with call to FM CRM_ORDER_MAINTAIN, else all your updation will remain in buffer and will have no effect in Database, which will let u feel as if things are not working they should be.

Solaris 10x86 and grub, bootloading and how to add new disk

In the latest version of Solaris 10 (1/06) it now uses grub to do the bootloading.
I cannot get grub to create a new partition on my new second disk.
BIOS sees my disk.
At first "format" would not see the disk. I ran "reboot -- -r" to fix this.
Now, I go into the grub shell with /boot/grub/bin/grub and attempt to run "partnew" -- the grub command to add partitions. It fails.
One of the arguments for 'partnew' is TYPE. However, I've googled my fingers to death, and nowhere can I find out what number I should use in type. The grub docs only say it should be a number between 0 and 0xff.
I want to multi-partition the second disk for linux/solaris/and or windows.
What if I take out disk1 containing solaris, move disk2 into that slot, then insert the windows installation cd and let it partition the disk.? Then put it back in slot 2....

Why are you trying to partition the disk with 'grub'? Since you've completed the installtion you can use 'fdisk' directly.
However I wouldn't bother. I'd just let the installer of whatever OS you're putting on do the right thing. Either Linux or Windows could partition it as you're installing.
Then you could go back and edit grub if you needed to so that they would boot properly.
This page talks about multibooting some different operating systems. You dont need to use it as a recipe, but you might find some of the concepts handy.

How to add Server disk on the Sidebar?

Hi,
I use the sidebar alot but I can´t figure out how to put a unmounted server disk in the side (to be opened later - as a shortcut). It will not go there. I can put folders from the disk on the sidebar but not the disk itself. Any ideas?

you can't do it with an unmounted disk directly. make an alias to the mounted disk and put the alias in the sidebar.

How to add an virtual disk device

I remember i have seen one doc describe how to add an virtual disk device in solaris system, but I forget it now, can somebody help me?

not sure what you are trying to achieve...
However you should not be referring to Luns via their logical device i.e. c0t0d0, but using the unique did device or the /global device. refer to scdidam -L which will list all the did devices across all nodes and map them to the logical device path.
