Checkpoint: Gaia on ESX – “No Hard Drives Have Been Found” Error

 

This article describes how to fix the error “No Hard Drives Have Been Found” when installing Checkpoint Gaia on ESX.

This is a simple one – I used to work round it by implementing an IDE drive instead of SCSI but actually it’s just due to the SCSI controller type. It happens when you choose a Red Hat machine which in turn sets the SCSI controller type to VMware Paravirtual as shown here below:

 

Gaia - Change SCSI Controller Type

All you need to do is go into the VM Settings, SCSI Controller, and change the SCSI controller type from “VMware Paravirtual” to “LSI Logic Parallel” or to “LSI Logic SAS.”

Job done! Screenshots available in SecureKnowledge here.

VMWare: Installing ESXi on HP ProLiant DL360e Server with RAID Controller B120i

Scenario: New HP ProLiant server Gen8 with B120i RAID controller, logical drive created on a RAID 1 array

Installing from a stock ISO, I came up against the error that “one or more disks have the same UUID” – this was after installing successfully and rebooting. Using the boot parameter “overrideDuplicateImageDetection” I was able to boot and use the vsphere client – this showed that both disks were visible to ESXi and were not being presented as a single logical drive.

After much wailing and gnashing of teeth and references to the controller not being supported, I came across a post suggesting that VMware has custom images. Indeed, I found the below:

HP Custom Image:

https://my.vmware.com/group/vmware/details?productId=327&downloadGroup=HP-ESXI-5.1.0U1-GA-25APR2013

Lo and behold, we now have a single logical drive instead of 2 separate ones:

VMWare: Backup ESXi Host Config Using vCLI

This process uses the vmware command line interface tools to backup your ESXi host configuration – a must have for disaster recovery when your ESXi host has to be rebuilt / cloned etc. The tools from the link below have been tested on all versions of ESXi from 3.5  onwards.

Note: This *DOES NOT* back up your virtual machines!!

1. Download the vCLI:

The installer will install the tools and also the ActivePerl sdk – the download link is currently here:

https://my.vmware.com/web/vmware/details?downloadGroup=VSP510-VCLI-510&productId=285

2. Use the esxcfg-cfgbackup.pl to backup your host configuration:

vicfg-cfgbackup.pl –server <server_name> -s <backup_file_name>

Example:

C:\Program Files (x86)\VMware\VMware vSphere CLI\bin>perl esxcfg-cfgbackup.pl — server 192.168.100.1 -s C:\Users\admin\Desktop\192.168.100.1.bin
Enter username: root
Enter password:
Saving firmware configuration to C:\Users\admin\Desktop\192.168.100.1.bin …

3. Use the esxcfg-cfgbackup.pl to restore your host configuration to a host:

esxcfg-cfgbackup.pl –server <server_name> -l <backup_file_name>

Note: this will cause the host to reboot once the process is complete.
