Issues with DRD on LVM

[Jayaprakash Subramanian]

Hello All,

I want to backup a HPUX root disk with DRD clone. The root disk is configured with LVM with 2 physical disks.

Here the ioscan output:

root@hpsvr # ioscan -fnC disk

/dev/dsk/c5t0d1 /dev/rdsk/c5t0d1

Now i added a new disk for 300 GB and tried to clone the root disk to the new disk using the following command -

/opt/drd/bin/drd clone -p -v -t -x overwrite=true /dev/disk/disk10

But the operation failed with the following errors. Can anyone provide me the details of this error.

root@hpsvr # /opt/drd/bin/drd clone -p -v -t /dev/disk/disk10

bit confused here, you say:
Now i added a new disk for 300 GB and tried to clone the root disk to the new disk using the following command -

But then you have:

root@hpsvr # /opt/drd/bin/drd clone -p -v -t /dev/disk/disk10

======= 08/20/10 06:47:57 PDT BEGIN Clone System Image Preview (user=root) (jobid=hpsvr)

So you have left off the -x overwrite-true as per the error message

Hi Melvyn,

Sorry, i mistyped the command. I Here the error message.

I used the following command :
/opt/drd/bin/drd clone -v -x overwrite=true -t /dev/dsk/c5t0d2

And the output is :

root@hpshop> /opt/drd/bin/drd clone -v -x overwrite=true -t /dev/dsk/c5t0d2

From error,
>>Converting legacy Dsf "/dev/dsk/c5t0d2" to "/dev/disk/disk10"<<

There is no /dev/dsk/c5t0d2 in your ioscan o/p.

post #ioscan -m dsf

Hi Bijeesh,

Thanks for your reply.

Here the output of "ioscan -m dsf"

The trget disk is present.But can you confirm the available space on this disk using #diskinfo.
Check the status of the disk using dd command.
Also what is the size of root vg?(#vgdisplay)

From error>>The total volume sizes in disk group: "drd_rootdg" exceed the available capacity by 56790Mb. >>
Is the current root vg size equals 56790Mb?

Compare the original LV size with the size showing in error message.
Also go through the drd log file /var/opt/drd/drd.log.
