- Red Hat Enterprise Linux 5.7 and newer
- Red Hat Enterprise Linux 6.1 and newer
- System registered using Red Hat Subscription Manager (RHSM)
rhn_check -vcommand fails on system registered using Red Hat Subscription Manager (RHSM):
# rhn_check -v ERROR: unable to read system id
- There is no substitute command, but following command can be used to check the available updates for a system registered using RHSM.
# yum check-update
rhn_checkcommand is used to pick up erratas,package scheduled through RHN Classic portal for system registered under RHN Classic. This command is executed by
rhnsdservice on systems manged through RHN Classic.
- In subscription manager there is no option to schedule package updates through portal . So system managed through Subscription Manager rhsnd service and rhn_check command is not available.
rhn_checkcommand does not work with Red Hat Subscription Manager.
