How to configure iLO on ESX-servers

Physical access it not necessary to configure ilo, I do it all the time with the hponcfg utility.... which in some ways is very scary that you can get physical access to the host from inside the host, but since the capability is there you might as well take advantage of it.

First you need to download and install the hponcfg utiltity from HP:
hponcfg 1.6.0-1 (linux)


Then you need to install it via rpm
#>rpm -ivh hponcfg-1.6.0-1.linux.rpm

Next, you will need to craft a .xml file to change your ip information and possibly your passwords. Note that you don't have to know the admin password to change the admin password and/or network settings. I'll post a sample one here which covers most of the basics. If you want to auth ilo against AD you'll have to do some more work. Download the attachment that I added, change to match your variables. Then you just need to apply the .xml

#>hponcfg -f configure_ilo.xml

configure_ilo.xml (994 bytes)

UNetbootin create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions

Introduction


UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on both Windows and Linux. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.

Extend'ing disks in WMware

http://www.penguinpunk.net/blog/?p=12

If you’re working in a VMware ESX environment, you should normally be able to use SAN-based disk expansion technologies, combined with diskpart in Windows, or vmkfstools in VMware ESX, to achieve the desired result.

In Windows, run the following commands to extend a basic volume:

diskpart

list volume

select volume x (where x is the number of the volume you wish to extend)

extend

exit

In VMware ESX, run the following command to extend a vmdk disk file:

vmkfstools -X 50G disk.vmdk

Note that the 50G value is the new size of the disk, not the extra space you require.

If you find yourself needing to extend a boot volume in Windows Server 2003, diskpart won’t be any help. Before you reach for the gparted ISO file, think about combining vmkfstools with another (test) Virtual Machine. Here are the required steps:

1. Backup your VM (VM1).
2. Shutdown VM1 and run vmkfstools against VM1’s disk file.
3. Attach the disk to a second guest (VM2).
4. Run diskpart on the volume (in this case it will probably be D: or something similar).
5. Once the volume is extended, shutdown VM2 and remove (but don’t delete) the disk from VM2’s config.
6. Attach the newly expanded volume to VM1.
7. Boot VM1.
8. Profit.

I hope that’s provided a starting point for further investigation into basic and dynamic disks. Remember, before converting every volume in sight to Dynamic, think very carefully about the ramifications of doing this.
