The BIG-IQ VE virtual machine fails to successfully start up due to exceeding a 180 second timeout while starting udev. The error reads something like, "udevd: worker failed while handling '/devices/pci0000:00/0000:00:07.1/ide1/1.0/block/hdc'". Afterward the prompt hangs indefinitely at "Setting up Logical Volume Management".
The BIG-IQ VE virtual machine hangs indefinitely, until corrective action is taken.
The BIG-IQ Virtual Edition (VE) virtual machine fails to successfully start because starting the udev process exceeds a 180-second timeout. The prompt hangs indefinitely at 'Setting up Logical Volume Management'. The system posts an error similar to the following: udevd: worker failed while handling '/devices/pci0000:00/0000:00:07.1/ide1/1.0/block/hdc'. This affects BIG-IQ VE VM boot up on Hyper-V where the VHD virtual disk has not yet successfully completed a full first-time initialization. This occurs when a virtual IDE CD/DVD device also exists on the VM, but without valid media being mounted.
To mitigate this error, perform the following procedure: 1. Shut down the VM. 2. Remove the CD/DVD IDE device. 3. Restart the VM. The BIG-IQ VE should now complete first-time device start up successfully, as indicated by a BIG-IQ log-in prompt. Once all first-time disk device initializations have been completed, the CD/DVD device can be re-added using the following procedure: 1. Shut down the VM. 2. Add and save the changes. 2. Restart. The VM should start up normally from now on, even without valid media mounted on the CD/DVD device. Note: This condition might be a common scenario when using a manually created Hyper-V VM with a BIG-IQ VHD virtual disk to deploy a BIG-IQ VE, or when using a default Hyper-V VM template to do the same. The best way to avoid this is to remove the CD/DVD device from the initial VM device configuration or template definition.
