To rescan your scsi disks (to look if a disk has been added) you can reread your scsi device by giving the following command:

<pre>
echo "- - -" >/sys/class/scsi_host/host0/scan
</pre>

It's very handy if you added a disk in VMware, don't want to reboot and have no flashy thingy disk-tools.

If you added space to your first disk you need to rescan your disk with:

<pre>
echo 1 > /sys/block/sda/device/rescan
</pre>

If you resized your disk with fdisk for example, but the disk was still busy for some reason and the partition table could not be rescanned you can use partprobe, but the following command also works to update your partitions:
<pre>
hdparm -z /dev/sdX
</pre>
If this gives you a "BLKRRPART failed: Device or resource busy" because some partitions on the drive are currently mounted, if you really don't want to reboot, you can try:
<pre>
partx -a /dev/sdX
</pre>
This will force partitions to be added and such.
