problem Creating LUN

[vmmax2479]

Hello All,

I have one ESX server with local storage. Vvhmba0:0:0 has 300+ GB available. trying to create a LUN with 20 GB and getting this message:

error during the configuration of the host: failed to update disk partition information. see attached for more details.

not sure if this helps but here is more info

# vmkfstools -P /vmfs/devices/disks/

This happens on occasion and I'm not really sure why. You may need to make the filesystem manually from the command line.

/usr/sbin/vmkfstools -C vmfs3 vmhba0:0:X -S <vmfs label>

You didn't display enough of your partition table in your screenshot to determine what X should be. But if you scroll down it should have type VMFS, or if you do

sfdisk -l /dev/sdX ( non compaq/hp )

sfdisk -l /dev/cciss/c0dX ( compaq / hp )

You can see which partition has type 'fb'

This actually looks kinda strange to me, if you look where the blocks start and end, it seems that there is a hole from 935 to 43938 which is where the majority of your drive space is. It looks like you've partitioned it in a way that is likely unrecoverable since you already have 4 primary partitions.

Did you take the defaults when you installed? Or did you custom modify the partitions?
