3 Specify the type of diagnostic partition.
Option Description
Private local
Creates the diagnostic partition on a local disk. This partition stores fault
information only for your host.
Private SAN storage
Creates the diagnostic partition on a non-shared SAN LUN. This partition
stores fault information only for your host.
Shared SAN storage
Creates the diagnostic partition on a shared SAN LUN. This partition is
accessed by multiple hosts and can store fault information for more than
one host.

5 Select the device to use for the diagnostic partition and click Next.
6 Review the partition conguration information and click Finish.
Verify a Diagnostic Partition
Use the esxcli command to verify whether a diagnostic partition is set.
In the procedure, --server=server_name species the target server. The specied target server prompts you
for a user name and password. Other connection options, such as a conguration le or session le, are
supported. For a list of connection options, see Geing Started with vSphere Command-Line Interfaces.
Prerequisites
Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Geing Started with
vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.
Procedure
u
List partitions to verify that a diagnostic partition is set.
esxcli --server=server_name system coredump partition list
If a diagnostic partition is set, the command displays information about it. Otherwise, the command shows
that no partition is activated and congured.
What to do next
To mange the host’s diagnostic partition, use the vCLI commands. See vSphere Command-Line Interface
Concepts and Examples.
Set Up a File as Core Dump Location
If the size of your available core dump partition is insucient, you can congure ESXi to generate core
dump as a le.
Typically, a core dump partition of 2.5 GB is created during ESXi installation. For upgrades from ESXi 5.0
and earlier, the core dump partition is limited to 100 MB. For this type of upgrade, during the boot process
the system might create a core dump le on a VMFS datastore. If it does not create a core dump le, you can
manually create the le.
N Software iSCSI and software FCoE are not supported for core dump le locations.
Prerequisites
