merging two raw disks

Hello,

From the following:
# newfs -F vxfs /dev/rdsk/c0t1d0
version 7 layout
71687369 sectors, 71687369 blocks of size 1024, log size 65536 blocks
largefiles supported
# newfs -F vxfs /dev/rdsk/c0t2d0
version 7 layout
71687369 sectors, 71687369 blocks of size 1024, log size 65536 blocks
largefiles supported

How do I put the 2 raw disks together without using vgcreate, vgextend, nor lvextend?

Thanks.

Jimmy

Cyanoacrylate?

What would you like to do with these disks
after you "put [them] together"?

Any reason for this restriction?

Is there some actual problem which you are
trying to solve? Is it a secret?

I don't know of a way to combine 2 disks together without adding them to a VG and having an LV span both disks.

It depends on what you wish to do. For some
purposes, creating a symbolic link on one
file system, pointing to a directory on the
other, may do enough.

With the proper hardware support (like, say,
a RAID adapter), two disks can be combined
(in more than one way) which would be
invisible to the overlying OS.

With no real problem specification, it's hard
to know what would solve the (unspecified)
problem (let alone what would best solve it).

And to you for the clear problem spec and the
prompt and informative answers to questions.
