Create/assign new disk in Proliant-server and ESXi

Download SPP…wait…create USB-stick…wait…boot server on USB-stick….wait….launch ACU..create array…wait..boot server…


If you used the HP ESXi ISO while installing ESXi (you did wrong if you didn’t) it’ll also install the hpssacli tool wich can make the above process in a couple of minutes. Just follow the steps:

  1. Enable SSH on host
  2. Login to SSH
  3. Run command: /opt/hp/hpssacli/bin/hpssacli ctrl all show config
  4. Look for the unassigned disk
  5. If single (or RAID0) disk, run: /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 create type=ld drives=<YOUR DRIVE ID> raid=0
    If RAID1 run: /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 create type=ld drives=<YOUR DRIVE ID>,<YOUR SECOND DRIVE ID> raid=1
    If RAID5 run: /opt/hp/hpssacli/bin/hpssacli ctrl slot=0 create type=ld drives=<YOUR DRIVE ID>,<YOUR SECOND DRIVE ID>,<YOUR THIRD DRIVE ID> raid=5

New HP USB Key Utility image tool

To create images of (primarily) HP Proliant Service Packs – now 2016.04 you need a tool from HP to do this. If you search for it, you’ll always get to the 1.7.0 version, which is not supportet for new SPP images.

Here is where you find the new USB Key tool to create bootable disks from SPP images, filename cp028009.exe.

vMotion fails after dvSwitch upgrade

I upgraded my vMotion switch from 5.1 to 6.0 and turned on enhanched LACP, somehow this “failed”. Didn’t think more about it right then, but DRS/vMotion started to generate alot of errors saying:

Migration [-1062718448:1458298954171534] failed to connect to remote host <> from host <>: Host is down.
vMotion migration [-1062718448:1458298954171534] failed to create a connection with remote host <>: The ESX hosts failed to connect over the VMotion network
The vMotion migrations failed because the ESX hosts were not able to connect over the vMotion network. Check the vMotion network settings and physical network configuration.
The vMotion failed because the destination host did not receive data from the source host on the vMotion network. Please check your vMotion network settings and physical network configuration and ensure they are correct.

What I had to do was to go in to the switch, assign old adapters to the newly created LAG interfaces and configure them as the only uplinks. vMotion_LAG_LACP

And off we go! 🙂

This change didn’t cause any network interruptions for me.

Move Management from dvSwitch to vSwitch vSphere6

This was a little tricky, so I thought I should share my way to do it:

  1. Migrate or shut down all guest systems on the host
  2. Put the host to maintenance
  3. Take notice of the dvSwitch configuration
  4. Disconnect the host from vCenter
  5. Log in directly to the host
  6. Add standard (vSwitches) with correct VLANs but don’t assign adapters
  7. Remove dvSwitches (you will now be disconnected from host)
  8. Log in to DCUI
  9. Configure Network: Network adapters – make the correct one active
  10. Configure Network: IP Configuration – insert your “old” IP from dvSwitch, add netmask and GW
  11. Log in directly to the host again
  12. The adapter will probably be in standby now, so just add another random network adapter, make that one standby and remove it again. It looks sexier now 🙂
  13. In vCenter – remove the host from the dvSwitch – or it will try to create it again.
  14. Reconnect the host in vCenter
  15. Exit maintenance mode
  16. You are now up and running with a “migrated” Management network.

HP ProCurve USB Console, HPN Serial Port

In the neat little “Quick setup guide” that is included when you buy a switch from HP with USB Console it says:

Note: You can also connect a console to the switch via the USB console port (cable not provided). For more information on using the USB console port, see the switch Management and Configuration guide. The manuals are available at

However, if you read the Management and Configation guide, you can’t find anything related to the USB console port, at least not in the 2920-guide.

If you connect your regular micro-USB-cable to a computer, you will see a “HPN Serial Port”. It’s this one we need a driver for. Download the driver here under “other”. This driver works with all HP ProCurve switches with USB console.

Just download install this one (x86 or x64 depending on your OS) and take a look what COM it gets assigned.

Use Putty (or your favourite serial console software) to connect to that COM-port.
