Mount a LUN on a Virtual Machine

I have one more question . I want to mount a LUN on the Virtual machine , is there a way to do it ?

Using vCenter i was able to add this LUN as a Hard Disk 2 ( Mapped Raw LUN )
I have LUN which contains some data on it , I want to mount it on a Virtual Machine .

i did add the LUN ( in vCenter ) as hard disk . below are the steps ,
Summary -> Edit settings -> Add Hard Disk 2  -> Raw Device Mappings  -> and selecting the appropriate LUN -> Store with Virtual Machine  -> Physical Setting -> Virtual Device Node .

When i reboot the machine .

I can see the partition in cat /proc/partition .

My question is how do i mount the partition . i dont want to format the partition as it had data on , Is there a way i can mount it ?

Bad approach. In that way you can't acces the FS of the LUN.

Need to know: Type os SAN (iSCI, FC), model of HBA ( if used ) release of VMWARE

yeah that is the same problem . i am not able to mount the lun as it does not recognise the filesystem

FC SAN ... HBA is Qlogic .. VMware is 4.1 .

thanks

NPIV (N_Port ID Virtualization) is the way to go. Too complex to detail here. Long story short, you assign several wwn to the same hba, then those wwn are taken by the VM's . Sadly it depends heavily in your HW but i think you wont have problems.

Please check these papers:

http://www.vmware.com/resources/techresources/10125 ( an example with wlogic and brocade switches, but i think it catches the idea)
