Attributes for nss

6.10 z/VM guest

You can find the attributes for re-IPL type nss in the /sys/firmware/reipl/nss sysfs directory.

name: Name of the NSS. The NSS name can be one to eight characters long and must consist of alphabetic or numeric characters. The following examples are all valid NSS names: 73248734, NSSCSITE, or NSS1234.
parm: If the NSS contains a Linux® instance, a 56-byte string of kernel parameters that is concatenated to the kernel parameters in the boot configuration. (Note the difference in length compared to ccw.)
A leading equal sign (=) means that the existing kernel parameter line in the boot configuration is ignored and the boot process uses the kernel parameters in the parm attribute only.

Note: You cannot load Linux kernel 4.13 or later from an NSS. The NSS must contain a Linux distribution with shared kernel support or another mainframe operating system, for example, CMS.
