Although the patch set was installed on the target guest domain in Patch the Target Guest Domain, the patch set must be installed again so that the newly created boot environment is properly patched. This ensures that the non-global zones are up to date with the latest required patches.
In this example, the installpatchset command and the recommended patches are installed from the shared storage.
root@TargetGuestDom# cd /ovas1/Downloads/10_Recommended_CPU_2018-10 root@TargetGuestDom# ./installpatchset --s10patchset
root@TargetGuestDom# shutdown -i 6
