Reconfigure virtual machine Device is a SCSI controller engaged in bus-sharing

When we were installing RAC on vmware, This error occured while adding already created hard disk with reuse option in vmware.
This happend because we created snapshot.
Solution is remove snapshot, add disk and after that if you want to have a snapshot take new one.

increase disk size in oracle linux on vmware

Here is video of these procedures

First of all our vmware guest operating system must be in shutdown mode.
we need to add hard disk to our box.
go to settings—>
click add, then choose hard disk.
check option use an existing virtual disk
then choose file which will expand.
add a new hard disk, go to settings and choose our disk, click utilities–expand and write new size.
power on virtual machine.

our guest system doesn’t see a new size
but fdisk shows  the new size

solution :
create new partition on /dev/sda

[root@oel6 ~]# pvcreate /dev/sda3
  Writing physical volume data to disk "/dev/sda3"
  Physical volume "/dev/sda3" successfully created
[root@oel6 ~]# vgextend vg_oel6 /dev/sda3
  Volume group "vg_oel6" successfully extended
[root@oel6 ~]# lvextend -L +18G /dev/vg_oel6/lv_root /dev/sda3  
  Extending logical volume lv_root to 43.60 GiB
  Logical volume lv_root successfully resized
[root@oel6 ~]# resize2fs /dev/mapper/vg_oel6-lv_root 43G
resize2fs 1.41.12 (17-May-2010)
Filesystem at /dev/mapper/vg_oel6-lv_root is mounted on /; on-line resizing required
old desc_blocks = 2, new_desc_blocks = 3
Performing an on-line resize of /dev/mapper/vg_oel6-lv_root to 11272192 (4k) blocks.
The filesystem on /dev/mapper/vg_oel6-lv_root is now 11272192 blocks long.

SOLUTION :¬†¬†¬†¬†¬† click¬† VM–> install VMware Tools :

copy this two file to desktop :

run .rpm file

then extract second file and  run vmware-install.pl file in terminal with its default settings

after that, you can share folder and see it in directory: /mnt/hgfs/
