After a Unified Communications server node is rebooted for any given reason, it will not boot the operating system (OS) back up. A reboot or power cycle of the server node will not boot the server node back up nor restore its services. The server node will remain offline and Applications Services will not be reinitialized.
Cisco has identified an issue where, after a successful VMware Tools upgrade, the initramfs image located in the boot partition is corrupted in varying degrees. This corruption of the initramfs image does not lead to a VMware Tools upgrade failure and the Unified Communications application continues to operate without exhibiting any issues. However, the next time the server node is rebooted for any reason the Linux BootLoader fails to load the initramfs image, which prevents the OS from booting back up.
After a planned or unplanned restart of a Cisco Unified Communications server node, its Virtual Machine Console will be stuck on a blank screen or display one or both of these errors:
Probing EDD (edd=off to disable)… ok
FATAL: Could not load /lib/modules/2.6.32-573.18.1.el16.x86_64/modules.dep: No such file or directory
Workaround for Cisco Unified Communications Manager, Unity Connection, Cisco Unified Communications Manager IM & Presence, and Session Management Edition
Customers can use these instructions in order to rebuild the initramfs image file. It is recommended that customers perform a full system backup prior to any server reboots.
ls -la /mnt/part1
ls -la /mnt/part2
The folder with the newest files in it identifies the active partition. Take note of which folder contains the active partition.
chroot /mnt/part1 or part2 (whichever one is identified as the active partition)
setenforce 0
/usr/bin/vmware-config-tools.pl -d
Note: The output of this command shows an error, which is normal and can be ignored.
Creating a new initrd boot image for the kernel.
Initctl: Unable to connect to Upstart:Failed to connect to socket /com/Ubuntu/upstart: connection refused
Unable to start services for VMware Tools
Execution aborted.

The removal of VMware Tools 9.10.5 build-2981885 for Linux completed

Solution
Customers are recommended to upgrade to the latest version. However, in order to prevent the issue from occuring prior to a recommended upgrade, customers can install ciscocm.CSCvq17528_vmtools_initramfs_v1.2.cop.sgn on each node in the cluster.
Note: Applying this COP will not resolve the issue after it has been encountered, but will prevent its occurrence.
Cisco highly recommends that customers upgrade to these Unified Communications application releases:
