Full Discussion: Move a LUN from one server to the other

Move a LUN from one server to the other
I have NetApp LUN that was presented to a Red Hat Enterprise Linux Server release 5.7 (Tikanga) machine.
But this LUN has already data, because it was being used on another server.
I can see the new LUN when running fdisk:
Code:
fdisk -l | egrep '^Disk' | egrep -v 'dm-' | grep -v identifier
Disk /dev/sda doesn't contain a valid partition table
Disk /dev/cciss/c0d0: 450.0 GB, 450064605184 bytes
Disk /dev/sda: 32.2 GB, 32212254720 bytes

so I think the new LUN is /dev/sda

But how do I go about mounting as a file system?
I cannot make a file system on it... because there is data already on it...

NAME

       chs - IBM ServeRAID PCI host adapter driver

DESCRIPTION

       The chs driver is the IBM ServeRAID PCI controller driver.

PRECONFIGURATION

   Known Problems and Limitations
       To  prevent  data  loss,  a  SCSI disk drive that is not defined as part of any physical pack within a logical drive will not be accessible
       through the Solaris operating environment.

CONFIGURATION

       Auto-configuration code determines whether the adapter is present at the configured address and what types of devices are attached  to  it.
       The IBM ServeRAID is primarily used as a disk array (system drive) controller.

       To  configure the attached disk arrays, you must configure the controller (using the configuration utilities provided by the hardware manu-
       facturer) before booting the Solaris operating environment You use the configuration utilities to set RAID levels, stripe parameters, cache
       mechanisms and perform other functions. For more information, see the user manual supplied with your hardware.
