If a VCMP guest is configured to be Provisioned or Deployed to multiple blades in a VIPRION chassis, and one of those blades is replaced or has a new installation of BIG-IP installed, the VCMP guest may fail to be Provisioned or Deployed to the newly installed/reinstalled blade. A message similar to the following may be logged to the LTM log (/var/log/ltm): <date> <time> slot# err vcmpd[#####]: 01510004:3: Guest (GUEST_NAME): Install to VDisk /shared/vmdisks/GUEST_IMAGE_NAME.img FAILED: Child exited with non-zero exit code: 255 When this issue occurs, the blade where the VCMP guest image fails to be installed is found not to be running the KVM kernel module: [root@CHASSIS_NAME:/S1-green-P::Active:Standalone] ~ # clsh 'lsmod | grep kvm' === slot 2 addr 127.3.0.2 color green === kvm_intel 179624 68 kvm 603109 1 kvm_intel irqbypass 13503 1 kvm === slot 3 addr 127.3.0.3 color green === kvm_intel 179624 0 kvm 603109 1 kvm_intel irqbypass 13503 1 kvm === slot 4 addr 127.3.0.4 color green === <<<<<<< no 'kvm' module shown for affected blade === slot 5 addr 127.3.0.5 color blue === === slot 6 addr 127.3.0.6 color blue === === slot 7 addr 127.3.0.7 color blue === === slot 8 addr 127.3.0.8 color blue === === slot 1 addr 127.3.0.1 color green === kvm_intel 179624 68 kvm 603109 1 kvm_intel irqbypass 13503 1 kvm
The VCMP guest fails to be Provisioned or Deployed to the newly installed/reinstalled blade.
This may occur if: -- VCMP is provisioned, and one or more VCMP guests are provisioned/deployed in a VIPRION chassis with multiple blades. -- One of the blades is replaced with a new blade (such as from an RMA replacement). -- The newly installed/reinstalled blade has a version of BIG-IP installed that does not match the BIG-IP version installed and running on the existing blades in the chassis. -- The newly installed/reinstalled blade must reboot multiple times to complete the installation of all required BIG-IP versions to match the existing blades in the chassis. -- One or more VCMP guests are configured to be Provisioned and/or Deployed to the newly installed/reinstalled blade's slot. -- The newly installed/reinstalled blade does not automatically reboot after successfully provisioning VCMP after the automated installation of the final (matching) BIG-IP version.
To work around this issue when it occurs, reboot the affected blade. -- From the console of the affected blade: reboot -- From the console of another blade in the chassis: clsh --slot=# reboot (where # is the slot number of the affected blade)
