Copying the dump to Linux

Copy the dump from the z/VM® reader using the vmur command.

Before you begin

Ensure that the device node for the reader device is available.

# ls /dev/vmrdr*
vmrdr-0.0.000c

The command output of the example shows the default device node for the reader device.

If the device is not available, you might have to load the vmur module and set the device online.

# modprobe vmur
# chzdev -e -a 0.0.000c

For more information about vmur, see Device Drivers, Features, and Commands on Red Hat® Enterprise Linux® 9.2, SC34-7750.

Procedure

Find the spool ID of the VMDUMP spool file in the output of the vmur li command:

# vmur li
ORIGINID FILE CLASS RECORDS  CPY HOLD DATE  TIME     NAME   TYPE DIST
T6360025 0463 V DMP 00020222 001 NONE 06/11 15:07:42 VMDUMP FILE T6360025

In the example the required VMDUMP file spool ID is 463.

Copy the dump into your Linux file system using the vmur receive command.

To convert the dump into a format that can be processed with the Linux dump analysis tool crash, convert the dump using the --convert option:

# vmur rec 463 -c myvmdump
