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:

Android: Updating Nook Simple Touch (NST) to Software Version 1.2.1 (UK)

So I just bought one of these from Currys for £29 but trying to update it to the latest version of firmware wasn’t happening.

You put the update.zip into the root directory of the NOOK and apparently it falls asleep then does an update; problem is that nothing appears to happen, you check the version and it’s still 1.2.0 and your update.zip has disappeared from the root directory.

Turns out that this is a software update from the US site and doesn’t want to be installed – you can force the issue by downgrading to version 1.1 of the firmware and then applying the US firmware file for 1.2.1 but you will then be on US firmware and I don’t know what that’s going to do for you.

So!

  • Grab the UK firmware update from here and copy it into the root directory
  • Turn off the NOOK by pressing the button on the back once
  • Wait for 20 or 30 seconds – you should see the update process starting
  • NOOK will reboot and when you log in you should have a bubble message on the notification bar telling you that you’re on the latest and greatest version!

Linux: Add a New HDD to a VM Without Rebooting

Add a New HDD to a VM Without Rebooting

This article describes how to add a new HDD to a VM without rebooting – handy if you need consistency of service and don’t have a redundant solution.

 

Solution:

Add a hard disk as usual through the VM settings. Check dmesg to see if the kernel has detected it automatically, if not:

echo "- - -" > /sys/class/scsi_host/host0/scan
fdisk -l

You should see something like:

Disk identifier: 0x00004fff

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048    30076927    15037440   83  Linux
/dev/sda2        30078974    31455231      688129    5  Extended
/dev/sda5        30078976    31455231      688128   82  Linux swap / Solaris

Disk /dev/sdc: 429.5 GB, 429496729600 bytes
255 heads, 63 sectors/track, 52216 cylinders, total 838860800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/sdc doesn't contain a valid partition table

/dev/sdc is the disk you just added, all you need to do is “fdisk /dev/sdc” to partition it and “mkfs.ext3 /dev/sdc1” to format the partition.

Job done.
