Solution Verified - Updated -

Environment

  • Red Hat Satellite 6.x

Issue

  • How to list errata for multiple hosts?
  • Query a Host Collection to list errata for the hosts.

Resolution

  • To list installable errata for multiple hosts, run the below command on the Satellite CLI,

    # for i in `hammer host list| sed -e '1,3d'|sed -e '$d'|cut -d' ' -f 1`; do echo -e "Errata details for:\n" `hammer host info --id $i|sed '2!d'`;hammer host errata list --host-id $i; done

    The output is of the below format,

    Errata details for:  
Name: Host1
2812 | RHSA-2018:1453 | security    | Critical: dhcp security update                                               | true       
1264 | RHSA-2017:1100 | security    | Critical: nss and nss-util security update                                   | true       
652  | RHSA-2017:2836 | security    | Critical: dnsmasq security update                                            | true       
Errata details for:  
Name: Host2
Errata details for:  
Name: Host3

    If there is no errata applicable, the the hostname is simply listed and it moves on to the next one.

  • The below script will list errata for hosts that are a part of a particular Host Collection by querying it as follows,

    # hammer host-collection list                        || Note the ID 
# for i in `hammer host-collection hosts --id <Host-Collection ID>| sed -e '1,3d'|sed -e '$d'|cut -d' ' -f 1`; do echo "Errata details for: " `hammer host info --id $i|sed '2!d'`;hammer host errata list --host-id $i;done

    Note: Replace <Host-Collection ID> with the noted ID.
