Adding space to ESX 3.0.1 after RAID5 expansion

Dear friends,

I've done a RAID5 expansion via IBM raid manager on a Vmware esx 3.0.1 machine and added a new 143Gb disk to the RAID5.

After that I've used esxcfg-rescan, esxcfg-vmhbadevs and fdisk to create a new partition in the empty space.

Now my fdisk -l looks like this (I've also a /dev/sda but that's not important):

Disk /dev/sdb: 586.7 GB, 586764255232 bytes

255 heads, 63 sectors/track, 71336 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot    Start       End    Blocks   Id  System

/dev/sdb1   *         1     53502 429754783+  fb  Unknown

/dev/sdb2         53503     71336 143251605   fb  Unknown

Now, the /dev/sdb1 is what I see in Vmclient as a Storage1 and where I put all my vm.

I need to create a Storage2 using /dev/sdb2 and see it in Vmclient as Storage2 for storing new vm.

Is it possible? How do I do that?

Regards,

Claudio.
