Add a vmdk to virtual RHEL5 server
To add a vmdk to a virtaul RHEL5 server, you first of all need to create the vmdk (d’oh!) – I won’t go into that here. Next, on the RHEL5 server do as root:
echo "- - -" > /sys/class/scsi_host/host0/scan (the spaces between the dashed are important)
This will cause the scsi bus to be rescanned and the new disk should be found. For the devicename check “dmesg”. Now you can partition the disk, add it to LVM or whatever.
