raw device mapping not showing

[phillbl]

Hi,

I have just created a 300gb disk on our san and presented it to our esx servers (3.5) and did a rescan. under configuration - storage adaptors the vmhba is correct and shows the lun id and capacity. The raw LUN is presented to all hosts

When i try to add the disk while the machine is switched off it does not show under 'select and configure a raw lun'

Any ideas??

Thanks

Remember when adding a Raw LUN you need to select the VMFS datastore where the RDM (the pointer to the RAW LUN) will be stored -the next step is where you select the RAW LUN to use -

i deleted and recreated my lun and the LUn then appeared. If i add the lun as a rdm to one machine should I also be able to add the lun to a second machine?

Is it possible to share the LUN to two vitrual machines allowing them to see the disk, without using clustering software i.e. MS Clustering

thanks
