Block Device Mapping
I'm been given a driver that is 90% complete.
It is 'block' device that can support many partitions. It is identified as a 'scsi' device even though it does not remotely look like a scsi device.
Currently, the single instance of the device controls upto 8 partitions.
When the minor device is created ddi_create_minor_node (that maps to a partition) with the DDI_NT_BLOCK_CHAN it creates a device with the names:
/dev/dsk/c2t2d190684ts0
/dev/dsk/c2t2d190684ts7
if the node is created with DDI_NT_BLOCK then it creates a device with the
names:
/dev/dsk/c2d2s0
/dev/dsk/c2d2s7
The device appears under the pci2f,4000/scsi device node, with scsi as part of the naming.
My questions are:
1) does a block device have to be known as a scsi device?
2) if does what additional properties must be supported. Are properties to be associated with the minor device numbers or instance of the device?
Well, I guess this may be thw wrong place to ask, as people in here tend to have already issues with their OVM installations and they probably don't know anything about OpenStack at all…
…I guess that's why you don't get any answer - wouldn't make sense for anyone to just reply, that they don't know OpenStack, would it?

accidentally we lost the rawdevice mapping file /etc/sysconfig/rawdevices. since we do not have OS backup we could not restore this file.
without this file ASM could not mount diskgroups....
Is it possible to find the device mapping from anykind of OS or Oracle Log/Trace files?
Oracle alert log contains only /dev/raw/raw1....Hi,
If the raw devices are still bound to the block device and you haven't rebooted since you lost you rawdevices config file then you could identify the major/minor numbers using /usr/bin/raw -qa
The example below shows that dev/raw/raw1 is bound to /dev/sdb1
[root@foo]# raw -qa
/dev/raw/raw1: bound to major 8, minor 17
[root@rmukvm214 dev]# ls -l sdb1
brw-rw---- 1 root disk 8, 17 Jun 17 16:14 sdb1
I'm not sure if this is the most elegant or safest way of piecing this information back together, as mentioned you might want to raise an SR with Oracle support.

Hi ChrisJ4203,
I see you didn't comment on editing the numbers in the keypad, I believe you have that problem too but you forgot to click "I have this question too".
By the way I've sent a couple feedback messages to Apple already and thanks for reminding me, I guess I'll have to be doing that more often.
Enjoy your day -

SOLARIS 10 with iSCSI Problem "not a block device"
Hi Guys.
I almost reached it to build an iscsi connection with a Netgear readynas 2100.
But I have still one Point which makes me a Problem!!!
Everything works, except mounting the device....
It always Sais me: "not a block device"
At the bottom you can see an output of the whole configuration that I did.

thanksHi,
To create Oracle ASM disks, there are some steps to do:
- Have raw Disks, and you don't have then you can create a pseudo disks with the command dd us yours.
- Install ASMLib
- Use the /etc/init.d/oracleasm to configure, create ASM disks
The command dd creates a pseudo-block disk, and this a solution: Create virtual RAW disks for Oracle ASM on Linux with single Hard Drive
# dd if=/dev/zero of=/asm/disk4 bs=1M count=2000
# losetup /dev/loop4 /asm/disk4
# /etc/init.d/oracleasm createdisk ASM4 /dev/loop4
After the creation, you should scan your ASM disks: Wadhah DAOUEHI - Creation of ASM disks on Oracle Linux using ASMLib
# /etc/init.d/oracleasm scandisks
# /etc/init.d/oracleasm listdisks

Can't have ASM mark a NFS file as an ASM disk : -is not a block device
Hello,
I’m trying to experiment with ASM for learning purpose. Because I don’t have access to a SAN, I am trying to use NFS files but I can’t manage to have ASM mark those files as ASM disks.
[root@localhost /]# /etc/init.d/oracleasm createdisk ASM_DISK_1 /mnt/asm_dsks/dg1/disk1
Marking disk "ASM_DISK_1" as an ASM disk: [FAILED]
The oracleasm log says: File "/mnt/asm_dsks/dg1/disk1" is not a block device
OK, more context now:
I am trying to install ASM on a RHEL5 virtual machine (on vmware).
[root@localhost /]# uname -rm
2.6.18-8.el5 x86_64
I followed this document:
http://www.oracle.com/technology/pub/articles/smiley-11gr1-install.html until I got stuck at the following command:
/etc/init.d/oracleasm createdisk ...
Now, the NFS filesystem comes from a Solaris 10 system (the only one that's available) running on a physical sun box (this one is not a virtual system).
I have tried many combinations. I tried creating the files on the linux VM, using dd. As root, as oracle. I tried creating them on the Solaris side, using mkfile... no matter what I try, I always get the same issue.
I tried to follow this document: Creating Files on a NAS Device for Use with ASM (http://download.oracle.com/docs/html/B10811_05/app_nas.htm#BCFHCIEC)
But nothing seems to work.
Any idea, recommendations?
Thanks,
Laurent.Hi buddy,
I guess the metalink note 731775.1 should help You.
In fact the procedure is:
- Create the disk devices on your NFS directory (using dd)
- Adjuste the permissions over those files (in this case, oracle:dba)
- Adjust the ASM_DISKSTRING at the ASM instance and setting the NFS directory in the discovery path
- Verify if they are available at v$asm_disk view
- Create the diskgroup using the the NFS disks that You have created.
Hope it helps,

Hi,
I want to write a block device driver in user mode so that the read and write calls from the FileSystem comes to user mode component than a regular kernel mode driver.
why i want to do this ... because I want to pass on the data coming to another apps and the data is near real time and large. So, I can't keep the block driver in kernel mode and do transfer of data from kernel mode to user mode.
Can this be done ... ? I have been looking at various things but nothing comes close. Any hints will be helpful.
Thanks
Tarrot .Well. The 2 user apps cannot talk directly as User APPs2 only understands block I/O requests as input so it has to have a FS over it which is ext3. User APPs1 is an application that runs over FS and writes to it like windows explorer.
The Problem is I am not able to find a way to write a user mode block driver. Why I want this to be user mode so that I can interface to Virtual disk below which is a user mode application, i.e. User Apps2.
I can write a kernel mode block driver there but it would not be efficient as I will have to push it from kernel mode to user mode for userapps2.
I hope it explains.... -
[SOLVED] /dev/root is not a valid block device
After trying to boot my system after a few days of it remaining off, it fails to boot with:

You are now being dropped into an emergency shell.

How to set permissions on devicemapper block device
I'm setting up a new RAC on RHEL5.1 using device mapper for multipath functionality.
How should I set the permissions for the block devices I'm going to use for ocr, voting and asm?
/dev/mapper/ocr1
/dev/mapper/voting1
etc.
Regards
Jon-Arne StorelvMarkus,
You are right about udev changing drastically between RHEL 4 and RHEL 5. The paper I referred to does include some guidelines for setting permissions for RHEL 5 as well. Here are some relevant extracts from the same pdf document:-
# From udev.permissions section
This file was obsoleted in later versions of the 2.6 kernels such as SLES10, RHEL5 and
Oracle Enterprise Linux 5 (OEL5), that functionality was merged into the rules files, which is explained later in this paper
...and later you will find this example in the document
For RHEL5, OEL5, SLES10
• Create a file /etc/udev/rules.d/99-raw.rules with the following content
with the following content
KERNEL=="raw[1-2]*", GROUP="oinstall", MODE="640"
KERNEL=="raw[3-5]*", OWNER="oracle", GROUP="oinstall", MODE="660"
/etc/udev/rules.d/50-udev.rules on Centos 5 gives plenty of examples of settings for all different types of devices. We really need to specify OWNER, GROUP and MODE for devices that RAC will use in a rules file.
Thanks,

Oracle VM Migrating virtual disk images to physical disks (block devices)
Hi,
For performance reasons, I'd like to migrate my .img file based virtual disks into physical partitions for VM's.
What is the safest possible way to migrate all partitions (including / partition) from a virtual disk to a block device?
Thanks,
Onurhobeygo wrote:

Your VMs need to be offline while you do this. Once you've done this, you can use Oracle VM Manager to remove the original .img file and replace it with the physical block device copy. This is low-risk, as the .img file will still be there if the new block device doesn't work.
Keep in mind that you will need a unique block device for every .img file you have. -
Mount: not a block device
i have created a solaris lun and trying to view the same from my solaris console. i want to perform i/o operations on the lun; how do i mount it? 'coz mount command gives "not a block device" error.
It depends on the specific driver, but you usually want to mount the 'dsk' device and not the 'rdsk' device.

Kernel 3.8.8-1 can't find any block device
After last kernel upgrade boot process stoped at "wait for root device".
There is nothing about initializing disk drives in dmesg and no block devices listed in /dev. There is no /dev/disk directory too.
I do have 3 disk drives. The devices are connected and present in bios. I am pretty sure they are fine.
Any idea what is going on?I didn't notice any errors on the upgrade. Fallback image is dead too. Where is my usb stick...

I wrote a filter driver over block device.
HI,
I wrote a virutal volume driver over block device , simlar with LVM,
I call it "vraid" ,I can create PV,VG,LV,it's working well.
However I cannot acess the sector over 2G , I can use the system
command "newfs -s XXXX /dev/vlun/rdsk/vlun0" to create a 2G filesystem.
If I use newfs /dev/vlun/rdsk/vlun0 to create the file system in the whole LV size,I found
If LV>2G ,the sector beyond 2G will not be located correctly. output as below.
seek\:XXXXXX Invalid argument.
So I use the system c ommand "truss" to trace the command mkfs (newfs invoke mkfs finally) ,
I found the llseek() is the matter,
When llseek() is invoked, I trace d all system callings,I found if I use llseek() to
locate some sectors, however there is no any callings ocurred in my drvier besides the
calling open() and close()/
I wonder to know why I always failed to acess the sector over 2G .
thanks and happies.

I have finished installing a 11g RAC on RHELv5 using EMC block devices for storage.
During installation i had partitioned the disks and changed ownership to oracle:dba
However everytime i reboot the server, the block devices ownership is reverted back to root and hence CRS doesnt fails to come up. So i end up doing a manual change in ownership and permission to bring up the CRS, ASM and finally the database.
Is there any way, i can automate this?
Thanks in Advance.You can setup this in udev permissnion file. In OEL5 it looks like:
[root@rick oracle]# tail -8 /etc/udev/rules.d/50-udev.rules
KERNEL=="sdb1", OWNER="root", GROUP="oinstall", MODE="640"
KERNEL=="sdc1", OWNER="oracle", GROUP="oinstall", MODE="640"
KERNEL=="sdd1", OWNER="oracle", GROUP="dba", MODE="640"
KERNEL=="sde1", OWNER="oracle", GROUP="dba", MODE="640"
KERNEL=="sdf1", OWNER="oracle", GROUP="dba", MODE="640"
KERNEL=="sdg1", OWNER="oracle", GROUP="dba", MODE="640"
