Appendix B: Using vm-support on VMware ESX Server
VM support is the command tool used to aid in diagnostics and/or troubleshooting of the ESX server. This
service tool is supported on ESX 4.0, 3.x, and 2.x. For VMware ESXi, use VI Client’s Export Diagnostics
Data option to get vm-support files.
The following procedure outlines the steps executed on the ESX 4.0/3.x service console. Enter the vm-
support command on the ESX service console. This script generates a .tgz file in the current directory.
Extract this file using the following command:
tar –zxvf “Vm-support file name”
Note that WinZip cannot be used to extract vm-support script output. You have to have a Linux machine to
extract these files. Once these files get extracted, a folder with the version of vm-support is created.
Important files to look at within this folder from the storage point of view are as follows:
• /tmp/vmware_xxx.txt – ESX version and patch information
• /var/log/messages – For hardware BIOS versions
• /tmp/chkconfig.*.txt – Confirm naviagent is installed
• /proc/scsi/lpfc or /proc/scsi/qla_2xx – HBA driver versions
• /tmp/esxcfg-swiscsi – Software iSCSI initiator information for ESX 4.0/3.x only
• /tmp/esxcfg-mpath – ESX path information for ESX 4.0/3.x
• /tmp/vmkmultipath – ESX path information for ESX 2.x
Additional information related to the vmkernel configuration can be found at:
• vmkpcidivy – Device configuration information available only on ESX 2.x systems
• /proc/vmware/config – For additional SCSI, disk, and file system configuration information
• /home/vmware/ – Contains VM configuration files information
• var/log/vmkernel and /var/log/vmkernel.1 – For additional troubleshooting information
