vmkdump - VMkernel dumper<br />
<br />
SYNOPSIS<br />
vmkdump OPTIONS<br />
<br />
COPYRIGHT<br />
VMware ESX Server is Copyright 2004-2007 VMware, Inc. All rights reserved.<br />
<br />
DESCRIPTION<br />
vmkdump manages the VMkernel dump partition.<br />
<br />
==== Usage ====<br />
vmkdump -d --devname /dev/<Linux device name><br />
-z --zdumpname outputName (optional)<br />
-n --newonly (optional)<br />
-s --slot slotnum (optional)<br />
Extract the log from a compressed dump:<br />
vmkdump -l --log zdumpname<br />
<br />
<br />
==== OPTIONS ====<br />
-d, --devname deviceName<br />
Specify the Linux console device that should be used to read the VMkernel dump. <br />
Note: This option should not be used after the dump partition has been set with the -p option. <br />
If the partition has been set, you need to stop and reset the VMkernel before using this option.<br />
<br />
-n, --newonly<br />
For each VMkernel dump that is produced, a count is kept of the number of times the compressed <br />
dump file has been read off the dump partition. When this option is specified, the compressed <br />
dump will only be read off the dump partition if the read count is zero.<br />
<br />
-z, --zdumpname compressedFileName<br />
When reading from the dump partition, this option specifies the name of the file to create with <br />
the compressed dump. By default the name is vmkernel-zdump.#, where # is a unique number.<br />
<br />
-s, --slot slotnum<br />
On dump partitions that reside on shared storage, multiple machines can share the dump partition. <br />
Because of this, the dump partition is split up into multiple slots. Generally, when retrieving a <br />
core dump, the physical machine's UUID is hashed into a slot number based on the total number <br />
of slots, and the compressed dump is automatically read from that slot. <br />
<br />
However, there may be situations where the machine that dumped core is no longer able to retrieve <br />
core dumps. In those cases, this option can be used to override the normal UUID hash algorithm <br />
for determining a slot. Note that the slot used during a core dump will be displayed on the PSOD.<br />
<br />
-l, --log compressedFileName<br />
Extracts the vmkernel log from the specified compressed dump file.<br />
<br />
<br />
==== Examples ====<br />
* Specify linux device to read the dump<br />
#vmkdump -d /dev/sda5<br />
<br />
Creates a file name vmkernel-zdump. # contained a compressed dump. # is 1 if no other compressed dumps are in the current directory, otherwise # is the lowest unused integer (ie, if up to vmkernel-zdump.5 exist, then it would create vmkernel-zdump.6).<br />
<br />
<br />
* Extract the zdump from the dump partition<br />
<br />
#vmkdump -d /vmfs/devices/disks/mpx.vmhba1:C0:T0:L0:2<br />
<br />
singleslot coredump<br />
<br />
<br />
created file vmkernel-zdump.1</div>
