You may get the following error when trying to uninstall HP Client Security:

Error 1325: Hewlett-Packard is not a valid short file name.

The solution, albeit a very odd one, is to disable all CD/DVD drives on your HP system through Device Manager (Start → Run → devmgmt.msc).

After the uninstallation, you can re-enable the device.

When using Microsoft Fail-Over Clustering with Cluster Shared Volumes or Clustered disks which are on a HP EVA storage box, you may run into a problem about the disk/volume only being accessible from one of the nodes of the failover cluster, usually the node on which the disk/volume was added. When trying to access the volume from another node (e.g. by moving the role using that volume to another node), the role will fail and complain that the disk/volume is not accessible. Moreover, in Disk Management, the disk is not accessible and does not show the size of the disk. This makes the use of a fail-over cluster rather useless as the role can only run on the one node that does have access to t  ...

Resetting a HP 1810-24 or -24G to factory defaults is easy:

  1. With the switch powered on, using both ends of a paperclip (or two separate paperclips), press and hold down the Reset and Clear buttons.
  2. Release the Reset button, but keep the Clear button held down.
  3. When all three mode LEDs (Act, FDx, and Spd) begin to blink, release the Clear button as well. When the self-test completes, the switch will be reset to factory defaults. Its IP address will be obtained through DHCP, or if there's no DHCP, it will be set to The password will be blank.

You can check the warranty and support contract status of your HP products online. This includes the base warranty, support contracts and/or carepacks.

Backups with HP Data Protector may fail with the following error:

REQUEST SENSE call failed. Possible cleanme signal detection failure

First, attempt to perform a manual clean of the drive, then try re-running the backup. If it fails again, power-cycle/reboot the drive/library.

If the error still persists, start HP Library and Tape Tools and run a drive assessment. You'll need to load a tape into the drive first. If the test fails (i.e. it returns an error code, such as internal error), call HP for support.

No_Light means there's no link on the port. Usually this indicates a problem with the physical wiring, either a faulty cable, or the TX/RX have been swapped.

No_Sync means there's a link on the port (so technically, wiring is okay), but there's a problem with the actual communication. The most common problem is a mismatch in speed on the switch port and the HBA on the other side. Your best bet would be to set the port's speed (temporarily) to auto-negotiate and see what speed is selected. If this does not work, try manually setting the port fixed to lower speeds.

The HP Network Config Utility provides advanced network configuration tasks for HP servers. It allows to set up NIC teaming, VLAN and more.

Uninstalling this software (e.g. after a P2V) is not possible through Control Panel (Add/Remove Programs) because it's not in the list like other HP software components. The only way to uninstall HP Network Config Utility is through an NIC's properties:

Open the network properties for any Ethernet NIC (doesn't matter which one).

In the This connection uses the following items: box (where you also set up IPv4/v6 settings), you'll see the HP Network Configuration Utilty.

Select (click) it, then click the Uninstall button. At the following prompt, click  ...

This article briefly explains how to integrate a HP Procurve and Cisco in one network, and make sure the VLANs are correctly routed across the two switches. I avoid using the term "trunk" as the definition of a "trunk" differs greatly between Cisco and HP: a trunk on a HP Procurve refers in fact to a feature like Cisco's EtherChannel, something entirely different.

Note that for VLAN trunking to work between the two, you need to use the 802.1q protocol. Other protocols, such as Cisco's VTP and ISL do not work on HP Procurve, as they are both Cisco-proprietary.

Multi-port trunking is also outside the scope of this article, but the basics remain the same.

For both switche  ...

Newer generations of HP Proliant servers (I had this with an ML110 G6) no longer show I/O controller messages directly on screen. Instead, they are masked by a graphical status screen.

Not having these messages also means you won't know when you have to hit that certain key (F8) to get into the RAID controller's configuration BIOS, which can be problematic.

To get out of the graphical status screen and see all the I/O messages, you can hit Space on your keyboard during startup. For me, this usually did not work right away, and I had to hit the key multiple times before it got out of the status screen.

When done correctly, you'll notice the I/O messages and intialisation messages of the RA  ...

Before installing ROK licenses on your virtual machines on VMware, be sure to allow SMBios reflection of the host to the VM's. Otherwise, authorization will fail with a This system is unsupported message.

To do this, go to the settings of your newly created VM. Click the tab Configuration, then click General, then the button Configuration Parameters. Add a new row:

SMBIOS.reflectHost = TRUE

If you have an HP laptop with an unknown device with hardware-id HPQ6001, it's the HP wireless button driver. Apparently some models on their support website lack this driver in the download list (it was the case for a HP Envy Touchsmart 1230eb).

I've encountered several issues on different HP Elitebook Folio 9470m ultrabooks, after updating the BIOS to its latest version (F.46).

One series of ultrabooks with an Intel Hybrid HD (with SSD cache) suddenly stopped working with a BSOD and refused to startup. Reinstallation with the original DVD oddly failed as well, either during installation, or after installing drivers. We've worked around the issue by using a Microsoft (non-HP) DVD to install Windows 8, then download the latest drivers from the HP site.

Another ultrabook with an SSD had another problem altogether, but still related to the BIOS update. After the update, USB devices started to fail intermittently. Both the   ...

If you have an HP Officejet Pro 8500, and have issues with your prints not maintaining the page layout (portrait or landscape), try enabling Print directly to printer in the printer properties.

It's quite easy to accidentally disable the touchpad on a HP Probook 4520s: double-tapping the left-top corner of the touchpad triggers the enable/disable switch. A LED indicates whether the touchpad is on or off: when the LED is lit, it means the touchpad is disabled, and vice-versa.

Users who are not aware of this feature can be looking to re-enable the touchpad for quite some time. A customer had a similar issue, and I was unaware the touchpad switch was actually built in the touchpad itself.

To re-enable the touchpad, all he had to do was double-tap the LED in the left-top corner. From a design perspective, it's quite neat, but not really user-friendly, or do we really have to read t  ...
