Cloning 18.2Gb drive to 36.4Gb drive on Tru64 4.0G How ?
I have successfully cloned the 18Gb drives in the past using dd if=/dev/rrz1c of=/dev/rrz2c bs=1024k. However although this appears to work fine onto a 36.4Gb drive, I am worried that I will not have the correct disk label on the drive. (I do not need the extra space.)
Do I need to worry? will this cause me problems down the line ? If so, can someone please suggest a more suitable method for cloning to a dissimilar drive. Do I need to disklabel the new drive, mark AdvFS partitions, then use some kind of vdump - | vrestore - method to transfer the data?

That's what I'd do. I can't think of a way
that the crude copy scheme would fail, but
I'd feel better about having a disk label
which agreed with reality.

Then do the clone using dd, and apply the disklabel to the new disk using the template immediatley after the clone.
This gives me a verifible set of advfs partitions and a larger spare 'h' partition, whilst retaining a correct disklabel.

Do you have normal (ufs or advfs) file systems or some raw partitions?
In case of file systems it is very easy to migrate data using vdump | vrestore.
If you want, I can make a procedure how to do that. Just give me more informations about file systems on that disk.

Re: Cloning 18.2Gb drive to 36.4Gb drive on Tru64 4.0G How ?
For info, referring to the above questions, I am using Tru64 4.0G Unix (old I know.)
with AdvFS partitions.
I am 'cloning' the disk, as the task is to refresh the disk hardware.
The dd method with application of the corrected disklabel afterwards works fine for me, but this is only good if you know of and retain all of the existing partition sizes. (I do not need the extra space of the new disk.)
