Including service levels of the hardware and the hypervisor

Red Hat Enterprise Linux 9.2 LPAR mode z/VM guest

The service levels of the different hardware cards, the LPAR level, and the z/VM® service level are valuable information for problem analysis.

If possible, include this information with any problem you report to IBM® Support for Linux® in LPAR mode or Linux on z/VM.

A /proc interface that provides a list of service levels is available. To see the service levels issue:

# cat /proc/service_levels

Example for a z/VM system with a QETH adapter and an FCP adapter:

# cat /proc/service_levels
VM: z/VM Version 7 Release 2.0, service level 2101 (64-bit)
qeth: 0.0.bdf0 firmware level V721
zfcp: 0.0.1916 microcode level 20600123

The service level information is automatically included in the DBGINFO file that IBM Support might ask you to generate when analyzing a problem for you.
