Manage Core Dumps with vicfg-dumppart
You can use vicfg-dumppart to manage core dumps.
The following example scenario changes the diagnostic partition. Specify one of the options listed in
“Connection Options for vCLI Host Management Commands,” on page 19 in place of <conn_options>.
Procedure
1 Show the diagnostic partition the VMkernel uses.
vicfg-dumppart <conn_options> -t
2 Display information about all partitions that can be used as diagnostic partitions. Use -l to list all
diagnostic partitions, -f to list all diagnostic partitions in order of priority.
vicfg-dumppart <conn_options> -f
The output might appear in the following format.
Partition name on vml.mpx.vmhba36:C0:T0:L0:7 -> mpx.vmhba36:C0:T0:L0:7
3 Deactivate the diagnostic partition.
vicfg-dumppart <conn_options> -d
The ESXi system is now without a diagnostic partition, and you must immediately set a new one.
4 Set the active partition to naa.<naa_ID>.
vicfg-dumppart <conn_options> -s naa.<naa_ID>
5 Run vicfg-dumppart -t again to verify that a diagnostic partition is set.
vicfg-dumppart <conn_options> -t
If a diagnostic partition is set, the command displays information about it. Otherwise, the command
informs you that no partition is set.
Configuring ESXi Syslog Services
All ESXi hosts run a syslog service, which logs messages from the VMkernel and other system components
to local les or to a remote host.
You can use the vSphere Web Client, or use the esxcli system syslog command to congure the following
parameters of the syslog service.
n
Remote host and port - Remote host to which syslog messages are forwarded and port on which the
remote host receives syslog messages. The remote host must have a log listener service installed and
correctly congured to receive the forwarded syslog messages. See the documentation for the syslog
service installed on the remote host for information on conguration.
n
Transport protocol - Logs can be sent by using UDP, which is the default, TCP, or SSL transports.
n
Local logging directory - Directory where local copies of the logs are stored. The directory can be
located on mounted NFS or VMFS volumes. Only the /scratch directory on the local le system is
persistent across reboots.
n
Unique directory name prex - Seing this option to true creates a subdirectory with the name of the
ESXi host under the specied logging directory. This method is especially useful if the same NFS
directory is used by multiple ESXi hosts.
