boot loop with message zfs_parse_bootfs: error 22 and panic vfs_mountroot: cannot mount root after patching (Doc ID 1662047.1)

Last updated on DECEMBER 21, 2015

Applies to:

Solaris SPARC Operating System - Version 10 9/10 U9 to 11 [Release 10.0 to 11.0]
Information in this document applies to any platform.

Symptoms

If after the installation of patches the system shows a panic like this (and might be continuously trying to boot in a loop)...

Unfortunately this error in itself isn't very helpful,  but once the system is booted from some alternative media an analysis of the root pool and its file systems and boot enviroment can be carried out.

Changes

Installation of one or more patches.
