System is virtual RedHat 4 Elsmp on VMWare. I have a new volume created and attached to the virtual server - RH4 ELsmp.  Is there a way to get the virtual OS to recognize the new disk so I can run fdisk etc then mount the new volume?

Login using root and run the command "kudzu"

kudzu detects and configures new and/or changed hardware on a system. When started, kudzu detects the current hardware, and checks it against a database stored in /etc/sysconfig/hwconf, if one exists. It then determines if any hardware has been added or removed from the system. If so, it gives the users the opportunity to configure any added hardware, and unconfigure any removed hardware. It then updates the database in /etc/sysconfig/hwconf.

That did not work. I've attached the fdisk -l and hwconf files
hwconf071509.txt
fdisk071509.txt

What is a Denial of Service (DoS)?

A DoS is a malicious attempt to prevent the normal operation of a computer system. You may frequently see the terms 'DDoS' (Distributed Denial of Service) and 'DoS' used interchangeably, but there are some subtle differences.

The fdisk.txt shows Six HDDs. Have you attached Six VMDK files to the Virtual Machine ?

Also have you added the new VMDK file to the VM ?

Yes. That the issue. the vmdk is added to the VM but fdisk -l will not see the disk until a server reboot. After reboot all works fine. I have been trying to find a solution for this for a year. In RH3 I could do the the ech0 "scsi add-single0device etc. but that does not work in RH4. there has go to be a way. The VMWare web sit ehas no answer.
